Articles marked * have been bought in the market, or were raised 

 on the laud of the station, and there can be no reasonable doubt 

 about fair sampling. The remainder was sent on with name recorded 

 above. Complete records of analysis will be published in our next 

 annual report. 



A careful examination of the preceding partial analyses of current 

 commercial feed stuffs cannot fail to show the existence of most 

 serious variation in the amount of the two most costly food constituents 

 — in case of the same kind. The differences noticed in that 

 direction affect in many instances in a marked degree, both the food 

 value of the particular article, as well as its comparative money 

 value. Some of these variations may be due to differences in the 

 processes at the time employed in the parent industry. The fact that 

 the majority of this class of feed stuffs are waste or hy products of other 

 industries renders them in an exceptional degree liable to changes in 

 composition. This feature in thir production deserves a most careful 

 consideration from a financial point of view., on the part of the buyer. 



Commercial fet^d stuffs are usually bought for their high percentage 

 of either nitrogen containing organic matter, or fat, or both. They 

 are used to enrich the daily diet of various kinds of farm live stock 

 iu both directions. This course is generally adopted on account of a 

 well known deficiency of most of our home raised coarse (odder 

 articles in regard to both food constituents — in particular of nitro- 

 genous matter. Farmers that do not raise a liberal proportion of 

 clover-like fodder plants are, in a particular degree, iu need of con- 

 centrated commercial feed stuffs rich in nitrogenous food constituents 

 to turn the excess of the non-nitrogenous food constituents, which 

 most of our current home-raised coarse fodder articles contain, to the 

 best possible account. 



The liability of pecuniary losses on the part of the buyer, in conse- 

 quence of exceptional variations in the percentage of nitrogenous 

 organic matter, crude protein, or fat, or of both is quite frequently 

 greatly aggravated by most unexpected serious fluctuations in the mar- 

 ket cost of leading feed stuffs. 



As we buy, in the majority of cases, the concentrated commercial 

 feed stuffs on account of their large proporton of nitrogen-contaniing 

 food constituents, it becomes of special interest to know at what cost 

 a given quantity oj nitrogen containing food constituents can be bought 

 in the form of different feed stuffs equally well. adapted under exist- 

 ing circumstances. A change in the market cost of one and the
