234 MY FARM.

 do not know how I could put the matter more 



strongly. 



With respect, to gypsum, and in close of this 

 special topic, I may say that I have found it some 

 times of service upon young clover, and sometimes 

 of no service at all. Upon old pasture land, it has, 

 with me, uniformly counted for nothing ; and again, 

 I have never failed to find an appreciable increase of

 the trenches at planting. It is certain that we have 

 no right to condemn the salt, simply because we 

 cannot detect the precise mode of its operation. That 

 mode, I am inclined to believe very complex, and 

 that no uniform law will ever meet the requirements

 flocculent precipitate of truth. 



Science and Practice. 



I REMEMBER once, in company with a crowd 

 of interested auditors, listening to a justly 

 distinguished pomologist, who, in the course of his 

 peroration in praise of scientific study, suggested the
