under to the depth of six inches ; the bone being applied in 

 the hill, and mixed with the soil as much as practicable. 



The corn came well, but ( with the exception of some 

 places where manure heaps had formerly been put,) it grew 

 generally very slowly indeed, and some hills not at all. The 

 worms destroyed some plants, and other plants, which were 

 not molested by them, seemed to die out for the want of 

 nutriment to keep them alive, so that the vacant hills were' 

 quite plenty and were filled by planting white beans. 



On a small portion of the field no bone manure was ap- 

 plied, and no appreciable difference marked the crop on this 

 portion. On another part unleached ashes, at the rate of 25 ' 

 bushels per acre, was applied in the hill at the time of plant- 

 ing, without bone. Here, I think, nearly double the quantity 

 of corn grew, it having started very well in the spring and 

 continued a good growth through the season. On another 

 small portion, " Gould's Muriate of Lime," at the rate of 600 

 pounds to the acre, was put in, on which the crop produced 

 was about the same in amount as on the other parts of the 

 field to which an application of bone was made. 



In this trial I could perceive no difference between "Day's 

 Bone Manure" and the "Flour of Bone" procured in Boston. 



I planted another lot of one acre; one-half with corn and 

 the other with, potatoes, having ploughed the sward under to 

 the depth of seven inches and spread and harrowed in about 

 four cords of compost per acre. I used Day's bone manure 

 at the rate of 500 pounds per acre in the hill for corn, and in 

 drill for potatoes, leaving a row in each lot in which none was 

 applied. I had a fair crop of corn and potatoes, but could 

 discover no inferiority in the crop by measure, from the rows 

 in which no bone was applied, as compared with the re- 

 mainder of the lot. 



The result of these trials satisfies me that I cannot afford 



to buy bone manure for these crops ; as you will perceive it 



failed entirely to start the corn earlier and more vigorously 



than it would have done without its aid, and I failed to dis-
