"The actual cost in many, if not all, of these cases has Food for 

 been very considerably reduced by special rates which are a 

 given where a number of farmers give a cash order for a car 

 lot or more. 



"The average cost of materials in these home-mixed 

 fertilizers has been thirty-four dollars and twenty-three cents 

 per ton delivered at the purchaser's freight station. Two 

 dollars will fully cover the cost of screening and mixing. 

 (From a dollar to a dollar and a half is the estimate of those 

 who have done the work.) The average valuation has been 

 thirty-four dollars and eighty-five cents per ton. On the basis 

 of these figures the average difference between cost and valua- 

 tion has been less than six per cent. In factory-mixed goods it 

 has averaged in round numbers eighteen per cent. 



"There is no longer any question as to the expediency of 

 home-mixing in many cases. From such raw materials as 

 are in our markets, without the aid of milling machinery, 

 mixtures can be and are annually made on the farm which 

 are uniform in quality, fine and dry, and equal in all respects 

 to the best ready made fertilizers."

Jersey and Holstein grades in milk were 

 kept in their places during the whole twenty-four hours, 

 and the manure carefully collected as it was excreted, and a 

 sufficient quantity of bedding and absorbents of known com- 

 position and weight were used to make the collection com- 

 plete. 



The cows consumed 114 pounds of hay, 893 pounds of 

 ensilage, 186 pounds of beets, and 154 pounds of a mixture 

 of 12 parts wheat bran, 9 parts cotton-seed meal, 3 parts 

 corn meal, and i part malt sprouts. The other details of 

 the experiment are shown in the table :
