W. G. WYMAN'S STATEMENT. 



Being requested by last year's Committee on Experi- 

 ments to notice and publish the condition of my field 

 this year, I offer the following statement of the contin- 

 uation in 1861 with grass, of my experiment com- 

 menced in 1860 with wheat, on the effects of different 

 kinds of fertilizers, as compared with none. The 

 division of the field into lots, and the numbers of them, 

 are the same as in 1860. 



The weight of clover hay and rowen, when thor- 

 oughly dried, on an average rod is as follows : 



No. 1, — hay, 41 lbs,; rowen, 21 lbs.; total, 62 lbs. Bate per acre, 4 tons and 1920 lbs. 



" 2 " 37 " " 12 " •« 49 " " " 3 " " 1840 " 



" 3 " 33 " " 21 " " 54 " " " 4 " " 640 " 



"4 " 28 " " 8 " " 36 " " " 2 " " 1760" 



At $10,00 per ton for the hay and rowen, the value 

 of the fertilizers for the present crop, per acre, is as 

 follows : 



Stable manure on No. 1, $20,80 for 2 tons and. 160 lbs. increase. 

 Ground bone " " 2, 10,40 " 1 " "'" 80 " 

 Superphosphate " " 3, 14,40 " 1 " " 880 " 

 As compared with no manure on No. 4. 



By comparing this with last year's statement, pub- 

 lished on the seventy-eighth page of the Report for 

 1860, it will be seen that the value of the fertilizers 

 for the two crops, — wheat in 1860, at $1,25 per bushel, 

 and hay in 186l/at $10,00 per ton, — is as follows: 



Stable manure, $25,80 pr. acre; cost, $18,00; net gain, $7,80 pr.acre. 

 Ground bone, 12,07 " " 7,50 " 4,57 " 



Superphosphate, 17,73 " " 6,25 " 11,48 "
