An extra price was paid for this in order to have it ground 

 finer, that the effects might appear sooner. At no part of the 

 season could any difference be seen. The yield of corn was 

 not at all improved by the bone dust; the part where none was 

 used being quite as good as the others. The field yielded 160 

 bushels of ears to the acre. Several hundred bushels of bone 

 dust have been used on grass land, and round fruit trees, but 

 no perceptible good has been derived from it. 



A small experiment with poudrette was tried on turnips. It 

 was a failure. They did quite as well side by side without 

 manure, and yielded four times the quantity where compost 

 was used. 



We have used salt from 15 to 25 bushels to the acre ; 

 have found it useful in destroying the cut worm, but never 

 thought it increased the crop, except sea-kale or asparagus, 

 which are both maritime plants. 



Liquid manure has been tried on grass, but the result was 

 not so favorable as anticipated. It appears to make the grass 

 grow very unevenly in bunches. 



The experiments we have made with lime are not yet ma- 

 tured sufficiently to determine the result, and my experience 

 with it is rather limited. 



From experience I know that the effect of manures is so 

 variable on different soils, that what is beneficial on one farm 

 is of no use on another ; as in the case of bone manure Avith 

 us. I have known land where no manure could be used with 

 a quarter of the benefit that bone dust was, and its not having 

 the desired effect on this farm ought not to militate against it 

 in the least. By chemical analyses of soils you can come gen- 

 erally to the result at once, and I believe it to be the only 

 true way of determining the propriety or expediency of one 

 application or another." 



To this I deem it useful to add some remarks of E. Phinney, 

 in a recent letter to me : 



" I am satisfied there is great economy in having a year's 

 stock of manure beforehand. Stable manure, when put upon the
