56 On Gypsum. 
1804. April. Rolled the seed corn of two hundred 
acres in like manner, leaving eight rows across the field, 
so as to mtersect with flat, hilly, sandy, stiff, rich and 
poor land. ‘Their inferiority was so visible, that from an 
eminence in the field, a stranger could point out the 
eight rows from the time the corn was three inches 
high, until it was all in tassel. In this the eight rows 
were a week later than the plaistered corn. The plais- 
tered corn stood the best, was forwardest, and produced 
the greatest crop. Its fodder dried about ten days sooner. 
1805. April. Plaistered as above the seed corn of 
30 acres of rich moist land, leaving eight rows. Corn 
injured by too much rain. No difference between the 
eight rows and the rest. 
May 7th. Replanted my corn on the high land, which 
had been much destroyed by mice, moles and birds, 
mixing two quarts of tar well, with one bushel of seed 
corn, and then plaistering it as above. The best reme- 
dy I ever tried against those evils, and the plaister as 
usual, accelerated and benefited the corn. 
April 25th. Plaistered three bushels on three acres of 
clover just up, sown alone on Jand half manured with 
coarse manure. A good crop. 
May 9th. Seven bushels on seven acres of forward 
wheat and clover. Wheat heading; land thin; the 
clover exceeded what such land had usually produced. 
No benefit to the wheat. : 
May 10th. Six busheis on six acres of very bad clover 
sown last spring. Clover just beginning to bloom. The 
season became moist, and it improved into a fine crop. 
May 10th. Last spring I left an unplaistered strip of 
20 feet wide quite across a field of clover. It was all cut
