124 PRACTICAL FARM CHEMISTRY. 



in that of kainit, at the rate of 100 pounds of kainit 

 to every 500 or 600 pounds of carcass. It is advis- 

 able to add a little kainit even to the flesh -manure 

 compost, and the further addition of 100 pounds or 

 so of some simple phosphate, as bone black or floats, 

 may be desirable for the purpose of rendering the 

 proportion of plant foods in the compost more 

 evenly balanced. At any rate this compost will be 

 very rich in nitrogen, far richer than the very best 

 of ordinary composted stable manure. 



Where fish and fish waste is readily procurable 

 at almost nominal rates, as in many places along 

 the sea shores, a cheaper source of nitro- 

 compost. ^^^ ^^^ phosphoric acid need not be look- 

 ed for. The material may be composted 

 in somewhat the same manner as described for car- 

 casses; but the compost will be comparatively richer 

 in phosphoric acid. Some kainit, say 100 pounds 

 to each 400 pounds of fish, will make a good addi- 

 tion. I would advise the very liberal use of muck, 

 both in the bottom of the compost heap and as a 

 covering for it. The finest piece of tomatoes I have 

 ever seen was grown on land heavily manured with 

 such fish compost.
