loam. If stored in a shed or in barrels there should be al- 

 ternate layers of loam (not sand) and manure in the pro- 

 portion of about 2 inches of the former to 1 inch of the 

 latter. 



There are other methods of preserving the fertilizing 

 constituents of the manure. One is to use gypsum. It 

 is a pretty good plan to sprinkle the dropping board with 

 gypsum and then mix more of it with the manure when 

 stored. In experiments at the Maine Station it was found 

 that t ' from the dung stored by itself or with sawdust, more 

 than half of this had escaped during the summer. The lot 

 stored with 40 pounds of plaster lost about one-third, while 

 the lot stored with 82 pounds plaster and 15 pounds saw- 

 dust suffered no loss/' The best preservation was secured 

 with kainit and acid phosphate, both with and without saw- 

 dust. For a flock of one hundred hens a good method of 

 preserving the manure would be to use about thirty pounds 

 of acid phosphate or kainit to about half a bushel of saw- 

 dust. Good dry earth or muck will take the place of saw- 

 dust. Lime and wood ashes should not be mixed with the 

 manure as they accelerate the loss of nitrogen.
