Thomas Jefferson to Charles Clay, 14 December 1812

To Charles Clay

Poplar Forest Dec. 14. 12.

Dear Sir

I go certainly tomorrow, wind & weather permitting, and both have abated considerably. I promised you some sprout Kale seed, which I now send. I do not remember to have seen Salsafia in your garden, & yet it is one of the best roots for the Winter. some call it the oyster plant because fried in batter it can scarcely be distinguished from a fried oyster. I send you some seed. it is to be sowed and managed as carrots & to be taken up at the same time & put away for winter use.

A supplement to your method of weighing Eng. & Portugal gold.

for French & Spanish gold, weigh & calculate as for English, and then deduct a cent & an half from every Dollar.

To calculate interest on Dollars at 6. per cent

Call them cents & multiply by 6. for a years interest.

halve the cents for a month’s interest.

third that half, & call them mills for a day’s interest. for example

required the interest of 246 . D. for 1–1–1.
say 246 cents
Multiply by  6 D C
gives  14.76 say 14. 76 for 1. year
halve them  123 or 1. 23 for 1 month
third that half  41 or 41. mills for 1 day Y M D
16. 0311 or 16.2 D. 3 Cents 1 mill for 1–1–1
Affectionately yours

Th: Jefferson
