MISLEADING EVIDENCE. 



We have recently received several samples of fertilizers with 

 requests that we would express an opinion as to the manure, 

 because their colors created suspicion ; indeed, there are hacen- 

 dados who judge manures almost entirely by appearance and 

 smell, and are thus liable to make serious mistakes. 



Appearance, smell, or color are no guides ; the only true test 

 in buying fertilizers is chemical analysis, although ^ the best test 

 is made by the crop itself. 



Nitrate of soda in appearance does not differ much from coarse 

 impure salt, and can be relied upon, when imported from the 

 mines in Chile, to contain approximately 16% of nitrogen. 



Sulphate of ammonia is a substance which is very variable in 

 appearance, it may be gray or white, or yellow, or blue, without 

 any real dift'erence in the quality ; it contains more nitrogen than 

 nitrate of soda, but being less soluble than the latter, it is conse- 

 quently less valuable. 



Superphosphate may be light gray, or a dark gray or brown ; 

 its tint simply depends on the color of the raw material from 

 which it is manufactured. The hacendado need not trouble about 

 the tint so long as the percentage of phosphate of lime is up to 

 the guaranteed standard. — Exchange.
