the difference between ground dunged at the Rate of 5 load or 200 bushels to the Acre and ground undunged." This experiment is typical of a great many others and it resulted, of course, in better yields on the manured ground and showed that two bushels of seed were preferable to four.

But if he ever set down the result of the experiment as regards the varieties, the passage has escaped me.
While at Fredericksburg this year visiting his mother and his sister Betty Lewis he learned of an interesting method of raising potatoes under straw and wrote down the details in his diary.

A little later when attending the Federal Convention he kept his eyes and ears open for agricultural information.

He learned how the Pennsylvanians cultivated buckwheat and visited the farm of a certain Jones, who was getting good results from the use of plaster of Paris.

With his usual interest in labor-saving machinery he inspected at Benjamin Franklin's a sort of ironing machine called a mangle, "well calculated," he thought, "for Table cloths & such articles as have not pleats & irregular foldings & would be very useful in large families." This year he had in wheat seven hundred acres, in grass five hundred eighty acres, in oats four hundred acres, in corn seven hundred acres, with several hundred more in buckwheat, barley, potatoes, peas, beans and turnips.
In 1788 he raised one thousand eighty-eight bushels of potatoes on one plantation, but they were not dug till December and in consequence some were badly injured by the frost.
