On the mlphuret of Lime as a Manuf^e. 81 



the corn thai grew on each row, the result was as 

 follows : 



One row, sulphuretted, gave - - 157 lbs. 

 One row, not sulphuretted, next adjoining 



the other, - - - - 117 



Gain, 40 lbs. 



One shorter row on a looser soil, sulphuretted, 95 lbs, 

 Oj)e adjoining, not sulphuretted, - 69| 



Gain, 25^ lbs. 



One adjoining, sulphuretted, - - 96 lbs. 



One near the same, not sulphuretted, 71 



Gain, i5 lbs. 

 In this field were 81 long rows, gain on each 



row, 40 lbs. - - 3240 lbs. 



38 short rows, gain on each, 25 lbs. 950 



Gained on the field, 4190 lbs. 



91 lbs. of ears give one bushel of shelled corn, and 

 4190 lbs. will give 46 bushels gained on a small field, 

 which produced, by a supposition of ihe quantity in each 

 wagon load, 172 bushels, and which, without the sul- 

 phuret, would have been 126 bushels. The greater part 

 of the soil of this field was a heavy white clay, broke up 

 the autumn preceding, and, what is singular and unex- 

 pected, the sulphuret had the greatest effect on the stiffest 

 clay. I think the cost of sulphuretting this field did not 

 exceed two dollars in the price of materials and labour.
