Notes on the Above Analyses. 



(1) The somewhat low percentage of protein in the case of all the 

 hays is explained by the ripeness of the grass before cutting. 



(2) The cooking (steaming) of potatoes did not affect materi- 

 2.\\y either their weight or composition. Samples XXX and XXXII 

 are from the same lot of potatoes, the former being anal^'zed before 

 boiling and the latter after. The quantity of potatoes cooked by 

 ''steaming" them was 1000 grams, which after cooking and while 

 hot weighed 1022 grams, and after cooling 995 grams, the loss being 

 due to evaporation of water while cooling. Tlie composition of 

 the dry substance of the raw and boiled potatoes is seen to be 

 practically the same. 



(3) A number of inquiries have been received as to the relative 

 value of cotton-seed meal and linseed meal, as now found in Maine 

 markets, for feeding purposes. With a view to answering these in- 

 quijies several samples of these two cattle foods were collected from 

 lots offered for sale in the State, the analyses of which are given 

 above. 



These analvses indicate that these two feedinoj stuffs as now sold 

 in this State are of good quality. The linseed meal is evidently "old 

 process" in which quite a percentage of oil still remains. 



The two meals differ chiefly in the amount of protein or nitrogen- 

 ous material which they contain, the cotton-seed meal having an 

 average in these cases of twelve (12) per cent more than the lin- 

 seed meal. The fat is about the same in both, but the linseed meal 

 contains more carbohydrate material (starch, sugar, etc.,) this 

 largely taking the place of the excess of protein in the cotton-seed 

 meal. Nevertheless, both foods are highly nitrogenous, and take 

 practically the same place in the ration. Both are valuable as a sup- 

 plement to the home raised foods that are poor in protein, such as 

 straw, poor hay, corn fodder, etc., the cotton-seed meal having some 

 advantage over the linseed in this respect. 



(4; The beef and pork scraps are seen to be highly nitrogenous, 



i. e., they contain about 57 per cent of albuminoids. Such waste 



products are valuable as a poultry food and at the price paid for the 



lots from which these samples were taken, viz., 2^ cents per pound, 



they can be purchased with profit. 



(5) The Koyal stock food cattle cake was sent to the Station for 



analysis by Messrs. E. W. Bhitchford & Co., Chicago, 111. This 



cake appears to be a sweet, clean food, prepared by mixing several
