three parts, and ftrewed fix bufhels of French Gypfam on No. 

 1 ; the fame quantity of the American Gypfum^ brought from 

 the Bay of Funda, on No. 2 ; and left the intermediate fpace 

 No. 3, without any. On cutting the firft crop, that year, litde 

 difference could be obferved ; the fecond crop, produced 

 double the quantity of grafs, where the Gypfum had been put ; 

 and the fucceeding year, the difference was flill greater in favor 

 of this manure. Early in Oftober, 1787, the clover lay was 

 ploughed once, about four inches deep ; was fowed with rye, 

 and in that rough ftate was harrowed. The rye was of a fuperior 

 quality, and double the quantity on No. 1 and 2, of that on 

 No. 3. After harvefl, the rye-llubble was ploughed, and 

 fowed with buck-wheat, when a llriking difference was Hill 

 obfervable in favor of the Gypfiimy and which continues in the, 

 prefent crop of Indian corn. 



2d. In April, 1787, I fowed three acres of potatoe-ground 

 (a light loam) with barley and clover. Jull as the barley was 

 above ground, fome Gypfum was ftrewed diagonally acrofs the 

 field, about eight feet wide. Litde or no difference could be 

 obferved in the barley ; but in the month of September follow- 

 ing, there was a ftriking difference in the clover, in favour of 

 the manure, which would have afforded a good crop of hay, 

 whilft the remainder of the field v;as but indifferent. I have 

 frequently put Gypfum upon grain, without obferving any 

 immediate diflereuce in the appearance of the crops.
