D. Farmyard Manure. 



The first essential is a liquid manure tank. 

 It is the liquid manure which contains most 

 of the volatile ammonia which is so valu- 

 able, and which can be preserved only in 

 an hermetically sealed tank. Therefore all 

 farm buildings should have a system of 

 drainage to lead the liquid manure to its 

 place of storage. 



In regard to the solids they should always 

 be kept in a covered yard. Yorkshire board 

 roofing is quite effective, and is the cheapest. 

 Strictly speaking, there is no doubt that the 

 most effective use of manure is not to store 

 the solids at all, but to put them on the land 

 each day, and plough in as soon as possible. 

 This practice is in vogue on many large 

 American dairy farms where the cows are 

 stall fed throughout the year. The yield 

 from manure so treated is greater than that 

 from manure kept even in a covered yard, 

 which in its turn is about twice as valuable 

 as manure from an open yard. Where cattle 

 are wintered in yards there should be a 

 liquid manure tank somewhere about the 

 middle of the yard, and from time to time
