122 On Sulphuret ofBarytes as a Mmiure. 



1. In the beginning of May I sowed with the sulphu- 

 ret a strip of wheat, about three perches in length and 

 three yards wide, in a short time the wheat assumed 

 a much deeper green, than that adjoining, and appear- 

 ed to grow with greater luxuriance, so that it could 

 be plainly distinguished at 15 or 20 perches distance, 

 and held its superiority until some time in June, when 

 there came a severe hail storm, that cut down all my 

 wheat, and totally destroyed the crop, and spoiled the 

 result of this experiment ; however, the young clover 

 felt the effect of the sulphuret, and grev/ with greater 

 luxuriance than I had ever experienced from plaster 

 of Paris, on the same ground, being a clay soil. 



2. About the same time, I sowed about 12 square 

 yards of clover, (a clay soil : ) it was a misty day, and 

 with a small sieve, I sifted near a pint on that quantity of 

 ground. In a day or two on examining it, I found most 

 of the stalks of clover, that had. grown four or five 

 inches high, and the weeds and garlick, to which 

 the sulphuret adhered, ^vere killed ; and nearly two 

 weeks of cool, dry weather having followed, it had an 

 unpromising appearance, but moist weather succeed- 

 ing, it recovered, grew rapidly, and when mown, gave 

 a greater crop than the adjoining grass that was plas- 

 tered. The second crop shews the effect more fa- 

 vourable, it appearing to afford double the quantity, 

 and growing with great luxuriance, while that adjoin- 

 ing is small and ripening the seed. 



3. When planting corn I put in each of 30 hills, (a 

 clay soil,) about half a table spoonful of the sulphuret, 

 dropped the corn on it, and covered it as usual ; it 

 came up well, and appeared to exceed what was plas-
