On Gypsum. 57 



except this strip, which was so bad as not to be worth 

 cutting. This spring on this day (clover beginning to 

 bloom) the strip was still much inferior to the adjoining 

 clover, which was good. I plaistered it at a bushel to 

 the acre, leaving the rest of the field unplaistered. It 

 equalled the adjoined clover in one month. 



May 16th. Sowed 23 bushels on 23 acres of corn in a 

 large field. Ploughed in part immediately, harrowed in 

 part, and left part on the surface ten days before it was 

 worked in. Corn four inches high. Weather moist. 

 No difference between the three divisions. The seed of 

 the whole field had been rolled. These 23 acres exceed- 

 ed the adjoining corn 25 per cent : its blades and tops 

 also dried sooner. 



June 15th. Plaistered at three bushels to the acre a 

 strip of goose grass or English grass — no effect on land 

 or grass. 



August 10th. Sowed 50 acres of thin sandy land in 

 corn at the time, in clover, and 40 bushels of plaister on 

 the seed, harrowing both lightly in. A moderate show- 

 er in four days, succeeded by a severe drought. Clover 

 sprouted and chiefly perished. A good cover of bird- 

 foot clover followed land so visibly improved, that a 

 stranger could mark the line of the plaistering by the 

 growth. That and the adjoining land in corn in 1808. 

 The difference visible in favour of the plaistered land. 



September 17th, to the 5th, of October. Sowed 88 

 busliels of yellow latter bearded wheat ; 171 of forward, 

 mixing half a bushel of plaister with one of wheat, a 

 little wetted. One bushel of forward, and three pecks 

 of latter wheat were sown to an acre. All among 

 corn. Two slips of 30 feet each were left across the
