Re: The amount of times...
Hmmm, 100C is where the vapor pressure of pure water is the standard atmospheric pressure at sea level. At 1 to 1.5km of elevation, the drop in temperature at where the vapor pressure of water is equal to the ambient pressure is enough to require adjustments to recipes when baking. The more natural point for 0C would be the triple point in water. Fahrenheit's scale was 0F being the coldest achievable temperature with water ice and NaCl, with 100F being core body temperature. A real SI scale fr temperature would be eV...

For doing thermodynamic calculations, the appropriate scales are Kelvin and Rankine, and there really isn't much difference in usability between K and R as all sorts of conversions need to be done to get answers in Joules or MWHr. Another "fun" problem is dealing with speed involves Joules being watt-seconds, while vehicle speeds are usually given in statute miles, nautical miles or kilometers per hour. A fun factoid is that 1 pound of force at one statute mile per hour is equal to 2.0W (1.99W is a closer approximation).

As for feet, a fair approximation is that light travels 1 ft/nsec, too bad the foot wasn't ~1.6% shorter as a light nano-second would be the ultimate SI unit of length. The current definition of an inch, 25.4mm, was chosen in the 1920's to allow machine tools to handle inches by having a 127 tooth gear instead of a 100 tooth gear.

FWIW, Jefferson wanted to base his unit of length on a "second's" rod, i.e. e pendulum whose length would have exactly one second period when measured at seal level and 45º latitude.

Don't get me started on kilograms of thrust.

Re: The amount of times...
From somewhere in the later half of the 19th century to ~1920, the US inch was defined as 39.37 inches equals 1m. According a ca 1920 issue of Railway Mechanical Engineer, the machine tool industry was making a push to defining the inch 25.4mm so that by using a 127 tooth gear to replace a 100 tooth gear a lathe could be set up to produce metric and imperial threads.

One problem with converting the US to pure metric is that almost all land titles use feet, not meters. The US legal definition of a foot was 1/66 of a chain, a mile was 80 chains (66x80=5280), a section of land under the Northwest Ordnance of 1787 (passed under the Articles of Confederation, NOT the Constitution), which was 6400 square chains and the acre being 10 square chains (640 acres per square mile). The surveys for the Townships (36 sections) didn't really start until ca 1796, so if the arrival of the metric standards had not been delayed by the storm and the English, the US might have re-written the 1787 law to use metric measurements.

Another problem with the US converting to metric was Herbert Hoover's success as Secretary of Commerce in setting national standards for pipes and other hardware.

One final note about metric versus imperial is that a nautical mile is defined as 1 minute of longitude at the equator, so works well with the degrees, minutes and seconds customarily used for angles. Metric navigation would favor a decimal system for expressing angles, i.e. the gradians.

Re: The amount of times...
"Fahrenheit's scale was 0F being the coldest achievable temperature with water ice and NaCl, with 100F being core body temperature."

Wrong on both counts. On Fahrenheit's original scale, 0 was the freezing point of a solution of ammonium chloride (NH4Cl), not table salt (NaCl). As neither compound is used directly on roads, the point at which it is not useful depends on which specific salt is being used in the area, and more importantly on where the compound has been applied and whether it has been moved or not. The temperature of the human body was not 100. It was 96. Of course, neither value is considered average for body temperature (and body temperature is incredibly variable in any case, whereas boiling points of things at a specific fixed pressure is stable). This is because the modern scale abandoned both limits by instead fixing 32 and 212 as the values for water freezing and boiling, moving both of the original bounds slightly and making use of the original scale inaccurate to modern users.

Re: The amount of times...
In 1700 it was much easier for a scientist to calibrate a home made thermometer using ammonium chloride cooling bath and a docile dog. The temperature of boiling water required a barometer at higher altitudes and calibration tables. The human armpit temperature of about 96 allows hand drawn hash marks in repeated halves. Many very early Fahrenheit thermometer are often marked every 3 degrees.

Re: The amount of times...
More importantly, for Fahrenheit the reference temperatures aren't 0 and 212; they're 32 and 96. 96 minus 32 is 64. And 32 and 64 are ... stay with me here ... powers of 2.

Fahrenheit based his scale on powers of 2 so that thermometers could be graduated by successive bisection (and then reflected to extrapolate outside that range, on the assumption that the mechanism was sufficiently linear within the desired range). That's an actual engineering reason, unlike "duh humans like powers of 10". There really isn't much reason to favor Celsius.

Kelvin, of course, is the one that matters. (Yes, Rankine works too, but for some SI operations Kelvin is more convenient.)

Celsius is today as much flavor-of-the-month as Fahrenheit is. The original justifications for them are no longer relevant; they're just a matter of taste.

Re: Hooray for Avoirdupois and pounds, shillings and pence
Auvoirdepois has nothing to do with pounds, shillings and pence. Precious metals are measure using the Troy system that has 20 ounces to the pound. That is why a pound of gold weighs more than a pound of feathers. 1GBP was originally worth a pound of gold hence 20 shillings to the pound.

In 1793, French scientist Joseph Dombey sailed for the newly formed United States at the request of Thomas Jefferson carrying two objects that could have changed America. He never made it, and now the US is stuck with a retro version of measurement that is unique in the modern world.

The first, a metal cylinder, was exactly one kilogram in mass. The second was a copper rod the length of a newly proposed distance measurement, the meter.

Jefferson was keen on the rationality of the metric system in the US and an avid Francophile. But Dombey's ship was blown off course, captured by English privateers (pirates with government sanction), and the scientist died on the island of Montserrat while waiting to be ransomed.

And so America is one of a handful of countries that maintains its own unique forms of weights and measures. //

When the UK settled in the Americas they brought with them a bastardized version of weights, measures and currencies. A Scottish pint, for example, was almost triple the size of an English equivalent until 1824, which speaks volumes about the drinking culture north of the border.

British measurements were initially standardized in the UK's colonies, but it was a curious system, taking in Roman, Frankish, and frankly bizarre additions. Until 1971, in the UK a pound consisted of 240 pence, with 12 pence to the shilling and 20 shillings to the pound. //

The French government felt that the newly formed nation wasn't being supportive enough in helping Gallic forces fight the British in the largely European War of the First Coalition. In something of a hissy fit, the French government declined to invite representatives from the US to the international gathering at Paris in 1798-99 that set the initial standards for the metric system.

Jefferson's plans were kicked into committee and while a form of standardization based on pounds and ounces was approved by the House, the Senate declined to rule on the matter.

McCullough says that it was Washington and his army that won the war for American independence. “He was not a brilliant strategist or tactician, not a gifted orator, not an intellectual. At several crucial moments he had shown marked indecisiveness. He had made serious mistakes in judgment. But experience had been his great teacher from boyhood, and in this his greatest test, he learned steadily from experience. Above all, Washington never forgot what was at stake and he never gave up.” Without Washington, there would be no America.

There are many things to celebrate during our nation’s semiquincentennial celebrations, and many men to honor for their part in our country’s birth: Thomas Jefferson, John Adams, Alexander Hamilton, Benjamin Franklin, and John Hancock among them. But no one looms larger than George Washington, who today seems almost mythical. At Washington’s funeral, Henry “Light-Horse Harry” Lee famously eulogized Washington as, “first in war, first in peace, and first in the hearts of his countrymen.” In 2026, it is our duty to ensure that honorific remains as true as when it was first spoken.

After some time, the VAX crashed. It was on a service contract, and Digital was called. Laura Creighton was not called although she was on the short list of people who were supposed to be called in case of problem. The Digital Field Service engineer came in, removed the disk from the drive, figured it was then okay to remove the tape and make the drive writeable, and proceeded to put a scratch disk into the drive and run diagnostics which wrote to that drive.

Well, diagnostics for disk drives are designed to shake up the equipment. But monkey brains are not designed to handle the electrical signals they received. You can imagine the convulsions that resulted. Two of the monkeys were stunned, and three died. The Digital engineer needed to be calmed down; he was going to call the Humane Society. This became known as the Great Dead Monkey Project, and it leads of course to the aphorism I use as my motto: You should not conduct tests while valuable monkeys are connected, so "Always mount a scratch monkey."

Laura Creighton points out that although this is told as a gruesomely amusing story, three monkeys did lose their lives, and there are lessons to be learned in treatment of animals and risk management. Particularly, the sign on the disk drive should have explained why the drive should never have been enabled for write access.

Watch as Freedom 250 transforms the iconic Washington Monument into the world’s tallest birthday candle in honor of our Nation’s 250th birthday. From New Year’s Eve through January 5th, 2026, a six-night projection-mapping spectacle will illuminate the Monument, creating an immersive, luminous canvas that narrates our Nation’s discovery, expansion, independence, and vision for the future. This Washington Monument illumination is the opening signature moment of a year-long series of marquee national events celebrating the triumph of the American spirit.

Acts will play every hour on the hour.

My y2k horror story.
I sat in a lonely office in Redwood City for a couple hours before and after midnight, playing with Net Hack[0]. My phone didn't ring once. As expected.

The cold, hard reality is that I and several hundred thousand (a couple million? Dunno.) other computer people worked on "the Y2K problem" for well over 20 years, on and off. Come the morning of January 1st, 2000 damn near everything worked as intended ... thus causing brilliant minds to conclude that it was never a problem to begin with.

HOWever, in the 2 years leading up to 2000, I got paid an awful lot of money re-certifying stuff that I had already certified to be Y2K compliant some 10-20 years earlier. Same for the embedded guys & gals. By the time 2000 came around, most of the hard work was close to a decade in the past ... the re-certification was pure management bullshit, so they could be seen as doing something ... anything! ... useful during the beginning of the dot-bomb bubble bursting.

As a global company, Sun had an early warning system for any Y2K problems: Its Australian office was 11 hours ahead of the UK office, so if any problems struck there, the company would get advance notice.

Which is why, as midnight neared Down Under, Rob's boss called Sun's Sydney office … then heard the phone line go terrifyingly silent as the clock ticked pas midnight. Rob said that "scared the hell out of my manager" – at least for a few moments, because the phone soon rang.

Yakisugi is a Japanese architectural technique for charring the surface of wood. It has become quite popular in bioarchitecture because the carbonized layer protects the wood from water, fire, insects, and fungi, thereby prolonging the lifespan of the wood. Yakisugi techniques were first codified in written form in the 17th and 18th centuries. But it seems Italian Renaissance polymath Leonardo da Vinci wrote about the protective benefits of charring wood surfaces more than 100 years earlier, according to a paper published in Zenodo, an open repository for EU funded research. //

Leonardo produced more than 13,000 pages in his notebooks (later gathered into codices), less than a third of which have survived. //

In 2003, Alessandro Vezzosi, director of Italy’s Museo Ideale, came across some recipes for mysterious mixtures while flipping through Leonardo’s notes. Vezzosi experimented with the recipes, resulting in a mixture that would harden into a material eerily akin to Bakelite, a synthetic plastic widely used in the early 1900s. So Leonardo may well have invented the first manmade plastic. //

The benefits of this method of wood preservation have since been well documented by science, although the effectiveness is dependent on a variety of factors, including wood species and environmental conditions. The fire’s heat seals the pores of the wood so it absorbs less water—a natural means of waterproofing. The charred surface serves as natural insulation for fire resistance. And stripping the bark removes nutrients that attract insects and fungi, a natural form of biological protection.

Big anniversaries are coming up in 2026: 200 years since the deaths of Thomas Jefferson and John Adams, 250 since the signing of the Declaration of Independence, 250 since Adam Smith published “The Wealth of Nations.”

But an anniversary this month deserves special attention, too — Dec. 16 marked 250 years since the birth of Jane Austen, one of the greatest novelists who’s ever lived.

She’s still read today, and millions of people who’ve never so much as peeked into the covers of “Pride and Prejudice,” “Sense and Sensibility” or “Emma” know Austen’s stories from their film and television adaptations. //

Like the Declaration of Independence and “The Wealth of Nations,” her works have stood the test of two centuries and more for a reason.

They are grounded in truths about human nature, and those truths are expressed in ways that enchant as well as instruct.

When Chevrolet introduced the Suburban in 1935, it didn’t just release a new vehicle. It invented an entire segment. The original Suburban wasn’t a pickup or a station wagon – it was both. Built on a light truck chassis and fitted with a wagon-style body, it carried passengers and payload with equal ease. No other vehicle on the market did that quite as well or looked quite like it.

Tocqueville made this point in “Democracy in America” by distinguishing between instinctive patriotism, rooted in custom and a sense of belonging based on place and personal loyalty, and reflective patriotism, based more on the opinions of free citizens, who understand their common liberties and their shared responsibilities with their fellow citizens.

This latter, more thoughtful form of patriotism, Tocqueville argued, is shaped by the exercise of individual rights within republican institutions and by what Tocqueville called “self-interest well understood.”

Indeed, one of the reasons Tocqueville admired America so much was that it bred both types of patriotism, a spirited attachment to American self-government as well as a reasoned devotion to the general principles of natural right and human liberty.

Tocqueville concluded that a patriotism in which particular loyalties and universal purposes reinforce each other was the source of the community bond and national cohesion needed to perpetuate democratic societies.

Without patriotism — instinctive patriotism for sure, but especially reflective patriotism — democratic peoples would become preoccupied with narrow, private concerns and come to neglect their civic duties.

The result is social division and civic apathy, as formerly self-governing citizens become themselves passive subjects in a modern, impersonal nation-state.

Without this dual patriotism of both the heart and the head, America’s thriving republic, Tocqueville famously warned, would be overtaken by a new form of democratic despotism that flattens the human spirit.

Today, patriotism is often misunderstood and criticized as an unthinking allegiance to chauvinistic urges.

Yet it is a love of country that is thoughtful as well as passionate — not “the impostures of pretended patriotism” Washington warned us against — that stands confident against the cultural relativism that plagues our society and undermines the defense of liberty by its disingenuous embrace and tendency toward despotic self-assertion.

Patriotism, rightly understood, has always been the civic antidote to what C. S. Lewis called “the poison of subjectivism.” //

Having rejected the Old World’s rule of accident and force in favor of government by reflection and choice, the Founders understood education — heretofore an elite privilege of the upper class and often a tool of state control — to take on a new civic role in service to popular government.

In a republican regime, built on equal rights and the consent of the governed, education not only shapes the private character that allows the individual to govern the self but also imparts the principles necessary for those individuals to practice the arts of self-government.

The student is transformed into the citizen through the expansion and deepening of the natural attachments as well as the cultivation of the civic knowledge necessary to perpetuate free government.

“The Education of youth is, in all governments, an object of the first consequence,” Noah Webster wrote in opening his 1788 essay on the topic. “The impressions received in early life, usually form the characters of individuals; a union of which forms the general character of a nation.” //

Education begins at home, when the habits and manners are established, first by parents, who have the primary responsibility for the upbringing of their children, and then by family, church, community and the first lessons of early instruction.

Like in the great nations of Europe, Webster maintained the formal educational system to be adopted and pursued in America should focus on the foundations of knowledge: reading, writing and arithmetic, as well as a basic understanding of the sciences and the outlines of geography and history.

But in republican America, Webster argued popular education must also “implant, in the minds of the American youth, the principles of virtue and of liberty; and inspire them with just and liberal ideas of government, and with an inviolable attachment to their own country.”

At a young age, this inculcation was especially to be done by teaching history: “every child in America should be acquainted with his own country. He should read books that furnish him with ideas that will be useful to him in life and practice. As soon as he opens his lips, he should rehearse the history of his own country; he should lisp the praise of liberty, and of those illustrious heroes and statesmen, who have wrought a revolution in her favor.”

Thomas Jefferson and James Madison concurred in a report they authored as commissioners of the University of Virginia.

Beyond improving the faculties and morals, the objects of a general education should be for the student “to understand his duties to his neighbors and country, and to discharge with competence the functions confided to him by either,” and “to instruct the mass of our citizens in these, their rights, interests and duties, as men and citizens.”

The objects of “the higher branches of education” — the colleges and universities scattered around the country — were “to develop the reasoning faculties of our youth, enlarge their minds, cultivate their morals, and instill into them the precepts of virtue and order” and “to form them to habits of reflection and correct action, rendering them examples of virtue to others, and of happiness within themselves.”

American higher education should “form the statesmen, legislators and judges, on whom public prosperity and individual happiness are so much to depend.”

Colleges and universities, too, had an obligation to make good citizens.

And the document around which this citizen education was to be constructed, the creed of America’s civic life and political identity, its temporal scripture and its epic poetry, was the Declaration of Independence.

The Declaration is the defining act of the great drama that is the American founding.

When Jefferson and Madison outlined an educational curriculum with “especial attention to the principles of government which shall be inculcated therein,” their first reading was the Declaration, which Jefferson called “an expression of the American mind.”

It is what the ancients described as the prelude to the laws, meant to define the regime and animate what is to come.

Although a “merely revolutionary document,” the Declaration of Independence contains, as Abraham Lincoln wrote on the eve of Civil War, “an abstract truth, applicable to all men and all times,” put there “that today, and in all coming days, it shall be a rebuke and a stumbling-block to the very harbingers of re-appearing tyranny and oppression.”

Lincoln also said once that public opinion “always has a ‘central idea,’ from which all its minor thoughts radiate.”

America’s central idea is the Declaration, and everything else radiates from that. //

By defining our common loves — our native country and our common commitment to republican government based on equal rights, political liberty and the consent of the governed — the Declaration unites our hearts and our minds in a civic friendship of enlightened patriotism.

We must know the Declaration if we truly are to love America.

From the new book “The Making of the American Mind: The Story of our Declaration of Independence.”

On Christmas morning, General Washington issued orders that the Continental Army was going across that river to kick some Hessian butts. He ordered rations cooked for three days, fresh flints to be put in every musket, and he also ordered that even the musicians and officers were to arm themselves, not with the usual swords and pistols, but with muskets. The Continental Army was betting everything. Bear in mind that in 1776, most of these men couldn't even swim; further, when this happened, the North American continent was in the throes of the Little Ice Age.

General Washington crossed with the first wave. He was leading his men, as a good commander should. By daybreak, the crossing was complete. //

When it was all over, the Hessians had suffered 22 killed, including the commander, Colonel Johann Rall, along with 83 wounded and almost 900 captured. The Americans suffered two killed and five wounded. By noon on the 26th, Washington's forces, with the Hessian prisoners, had crossed safely back across the Delaware into Pennsylvania.

Historian David Hackett Fischer later wrote of this event:

Until Washington crossed the Delaware, the triumph of the old order seemed inevitable. Thereafter, things would never be the same again.
Unlike the battle of Midway, the attack on Trenton wasn't the turning point - but it was a turning point. After Trenton, after that nighttime crossing of an icy river, in the depths of one of the coldest winters in written history, American determination and capability were never again in doubt.

Computer History Museum software curator Al Kossow has successfully retrieved the contents of the over-half-a-century old tape found at the University of Utah last month.

UNIX V4, the first ever version of the UNIX operating system in which the kernel was written in the then-new C programming language, has been successfully recovered from a 1970s nine-track tape drive. You can download it from the Internet Archive, and run it in SimH. On Mastodon, "Flexion" posted a screenshot of it running under SGI IRIX.

https://archive.org/details/utah_unix_v4_raw //

The very first version of Unix, later known as the "Zeroth edition", was hand-coded in assembly language by Thompson in 1969. He wrote it for a spare PDP-7 at Bell Labs, a Digital Equipment Corporation minicomputer from 1965. The PDP-7 was an 18-bit machine: it handled memory in 18-bit words. This was so long ago that things like the eight-bit byte had not yet been standardized. PDP-7 UNIX was reconstructed from printouts between 2016 and 2019.

It did well enough that a few years later, Thompson got his hands on a PDP-11. Thompson rewrote his OS for this 16-bit machine – still in assembly language – to create UNIX First Edition. At first, the machine had a single RS11 hard disk, for a grand total of half a megabyte of storage, although the rebuilt source code is from a later machine with a second hard disk.

Latest results from a recently discovered ancient Roman construction site confirm earlier findings.

Back in 2023, we reported on MIT scientists’ conclusion that the ancient Romans employed “hot mixing” with quicklime, among other strategies, to make their famous concrete, giving the material self-healing functionality. The only snag was that this didn’t match the recipe as described in historical texts. Now the same team is back with a fresh analysis of samples collected from a recently discovered site that confirms the Romans did indeed use hot mixing, according to a new paper published in the journal Nature Communications. //

Then archaeologists discovered the remains of what was once an active construction site in Pompeii, with tools and piles of raw materials scattered about, a half-built wall, completed buttresses, and even mortar repairs to an existing wall. Masic described it as a veritable “time capsule” holding even more secrets about how the Romans made their concrete.

Masic et al.’s latest isotopic analysis of samples taken from the site confirms that the concrete had the same lime clasts as those used to build Privernum. Intact quicklime fragments showed they had been premixed with other dry raw materials—a crucial early step in a hot mixing process. Furthermore, the volcanic ash used in the cement contained pumice, and those pumice particles would chemically react with the surrounding solution over time to create new, strengthening mineral deposits. As for Vitruvius, Masic suggests that the historian may have been misinterpreted, pointing to a passing mention of latent heat during the cement mixing process that might indicate hot mixing.

Thirty years ago today, Netscape Communications and Sun Microsystems issued a joint press release announcing JavaScript, an object scripting language designed for creating interactive web applications. The language emerged from a frantic 10-day sprint at pioneering browser company Netscape, where engineer Brendan Eich hacked together a working internal prototype during May 1995.

While the JavaScript language didn’t ship publicly until that September and didn’t reach a 1.0 release until March 1996, the descendants of Eich’s initial 10-day hack now run on approximately 98.9 percent of all websites with client-side code, making JavaScript the dominant programming language of the web. It’s wildly popular; beyond the browser, JavaScript powers server backends, mobile apps, desktop software, and even some embedded systems. According to several surveys, JavaScript consistently ranks among the most widely used programming languages in the world. //

The JavaScript partnership secured endorsements from 28 major tech companies, but amusingly, the December 1995 announcement now reads like a tech industry epitaph. The endorsing companies included Digital Equipment Corporation (absorbed by Compaq, then HP), Silicon Graphics (bankrupt), and Netscape itself (bought by AOL, dismantled). Sun Microsystems, co-creator of JavaScript and owner of Java, was acquired by Oracle in 2010. JavaScript outlived them all. //

Confusion about its relationship to Java continues: The two languages share a name, some syntax conventions, and virtually nothing else. Java was developed by James Gosling at Sun Microsystems using static typing and class-based objects. JavaScript uses dynamic typing and prototype-based inheritance. The distinction between the two languages, as one Stack Overflow user put it in 2010, is similar to the relationship between the words “car” and “carpet.” //

The language now powers not just websites but mobile applications through frameworks like React Native, desktop software through Electron, and server infrastructure through Node.js. Somewhere around 2 million to 3 million packages exist on npm, the JavaScript package registry.

The Three Bible Timelines: Why and How They Differ
February 25, 2013

Last updated on November 3rd, 2015 at 01:48 pm

The three most widely used Bible Timelines are:

• Ussher’s Chronology: included in the margins of the Authorized King James Bible is based on the Masoretic text of the Hebrew Old Testament. The Masoretic text had an unbroken history of careful transcription for centuries.

• Thiele: a modern Biblical chronologist whose work is accepted by secular Egyptologists as well as biblical scholars – often used by modern Evangelicals.

• The Septuagint: on which the Catholic Bible is based, is the Koine Greek version of the Hebrew Bible translated between 300 BC and 1 BC.

Most people who try to compute a Bible timeline are faced with the same dilemmas. The Rvd. Professor James Barr, a Scottish Old Testament scholar, has identified three distinct periods that Ussher, and all biblical chronologists had to tackle:

• Early times (Creation to Solomon). Anyone who starts out reading the Bible with Genesis, as many people do, can easily compute the years from Adam to Solomon.

• Early Age of Kings (Solomon to the destruction of the Temple in Jerusalem and the Babylonian captivity). Now we have gaps in the record.

• Late Age of Kings (Ezra and Nehemiah to the birth of Jesus). Here events are just mentioned with no possible way to link or calculate time frames. Historians use well known secular kings or events mentioned in the Bible (i.e., Nebuchadnezzar) to calculate the Bible dates.

What does appear to be true is that in 1902, when young Archie was just eight years old, he did sneak a tree into the White House and kept it upstairs in a closet. He supposedly had White House staff members help him find lights and ornaments, and he added a gift for each of his family members, including the Roosevelts' pets. On Christmas morning, he finally shared the surprise with his family, who were delighted by it. The president even let his children continue the tradition after that.

Here's what Roosevelt wrote in a letter to a friend about that Christmas:

Yesterday Archie got among his presents a small rifle from me and a pair of riding boots from his mother. He won’t be able to use the rifle until next summer, but he has gone off very happy in the riding boots for a ride on the calico pony Algonquin, the one you rode the other day. Yesterday morning at a quarter of seven all the children were up and dressed and began to hammer at the door of their mother’s and my room, in which their six stockings, all bulging out with queer angles and rotundities, were hanging from the fireplace. So their mother and I got up, shut the window, lit the fire (taking down the stockings of course), put on our wrappers and prepared to admit the children.
