STATEMENT OF DAVID CHOATE. 



Statement of experiments made with Bone Flour, manu- 

 factured by the Boston Milling and Manufacturing Company. 



As requested by the Trustees at their late meeting, I sub- 

 mit the following statement : 



I received one barrel of the Flour of Bone, manufactured 

 as above, on the I5th of May last; and on the 19th, and again 

 on the 2od, I applied it to Indian corn as follows, viz. : — 

 premising, however, that the whole field had been manured 

 uniformly from the barnyard, the manure having been spread 

 and harrowed in. I took six rows, each 36 hills in length ; 

 and upon the first two, which I call lot No. 1, I applied one- 

 third of a pint to each hill. The corn in all six of the rows 

 was just coming up. 



The two middle rows (say No. 2) had no bone at all. 

 Upon the remaining two rows, No. 3, everything being equal 

 as before, except that it was four days later, I applied one- 

 sixth of a pint to each hill, just half the amount put in the 

 case of No. 1. The quantity applied to No. 1, was at the 

 rate, very nearly, of 17 bushels per acre, of 3240 hills; and 

 upon No. 3 just half that amount, or more exactly, 8.43 bush- 

 els per acre. 



The mode of cultivation through the season was the same 

 in all six of the rows. 



The crop was harvested on the 29th of October. I should 

 have added, that no one, whose attention was called to the 

 experiment, could satisfy himself that the bone flour either 

 hastened or retarded the growth or maturity of the crop in 

 any degree whatever. 



The weight of the corn was as follows : 



In rows, No. 1^ with 17 bush, bone to the acre, 109^ f>ounds. 

 No. 2, with no bone, 98 f " 



No. 3, with 8.43 bush, bone to the acre, 100^ "
