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 intersect 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 land half manured with 

 coarse manure. K 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 lOth. Six bushels 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
