46 BOAED OF AGRICULTURE. 



of roots, and very little leaf; but on that part of the field 

 where the wool-waste had been applied, the plants had gone 

 almost entirely to leaf, rather than root. The lesson to be 

 derived from this is, that these chemical fertilizers, applied 

 wrongly, can bring no profit. As applied to grass, the wool- 

 waste had produced a profit, but as applied to turnips, it had 

 produced no profit ; in fiict, it had resulted in loss, because 

 the turnips were not so good for it. 



Mr. Slade, of Somerset. Did I understand the Doctor to 

 say that he applied the nitrogen to the surface for the corn-crop ? 



Dr. Stueteva^t. I would recommend applying nitrogen 

 to the surface. 



Question. How much corn can Professor Stockbridge 

 grow with seventy-five dollars, which he admits he paid for 

 his manure ? 



Prof. Stockbeidge. I do not know. I can only answer 

 the question by referring to the experiments reported. Mr. 

 H. C. Comins says, "I bought twenty dollars' worth of 

 materials. I applied it to one acre of land, and got ninety- 

 three bushels of shelled corn." Give me land enough, and 

 with seventy-five dollars I can grow four times that amount 

 in value of corn. 



Mr. Slade. I suppose there is not a gentleman here who 

 does not intend to ask Professor Stockbridge for his formula, 

 and I ask him if he will give it now. 



Prof. STOCKBEroGE. I see by Mr. Slade's manner of 

 remark, that there is a feeling here that there is some secrecy 

 about this matter. There is no secrecy whatever about it. 

 It is all just as plain and open and as common, to a large pro- 

 portion of men, as it is to know of the use of barn-yard 

 manure or muck. There is nothing secret, there is nothing 

 behind it. The inquiry is made for the formula. I did not 

 expect that I should be asked to give the formula here, but to 

 meet this want of the farmers of New Ensfland, all the formulas 

 from which I have worked will be published in the report of 

 the Agricultural College to the legislature, and go broadcast 

 throughout the Commonwealth. I am willing to criye to this 

 audience my formulas, but I am not willing that the reporters 

 should put them down, or that they should be published in
