I was never much good at math. I liked patterns and making the calculator make words if you loaded in a certain formula. "Esso Oil" could appear on the small LCD screen if you knew the right numbers. So I never became an accountant or an engineer. I was reminded of this when I came across this 1674 entry in the minute books of the Hudson's Bay Company in London, part of that year's provisioning of that year's expedition to Canada's Arctic coast. I understand that 17 men x 28 days x 3 months x 3 quarts = 5 tunns. Or 4284 quarts. But is it true that 4284 quarts equals 5 tunns? What is a tunn? Is there 4284 quarts ÷ 4 quarts in a gallon ÷ 5 tunns mean there are 214.2 gallons to a tunn? This would be a measure way off the pottle chart of the 1840s. Unless I have the math wrong.
Which is exactly the point at which I try to make words appear on my Texas Instrument solar powered pocket calculator in early 1981 or look out the classroom window daydreaming of Friday nights, past or future.
