FISH. 



The refuse of all kinds of fish afford sources of the richest and 

 most desirable kind of manure, and it is unfortunate that some 

 wholesale and cheap method of popularizing it has not been forth- 

 coming. When cooked, deprived of its oil and water by heavy 

 pressure, and thoroughly dried, it is easily reduced to a fine powder, 

 of which the following is an average analysis : 



Moisture 1.30 



^Nitrogenous Organic Matter 78.01 



Alkaline Salts 5.30 



Chloride of Sodium Traces. 



Phosphate of Lime 15.00 



Magnesia 0.33 



Carbonate of Lime Traces 



Insoluable Siliceous Matter 0.06 



100.00 

 *Equal to Nitrogen 10.00 



BLOOD, WOOL-REFUSE, HAIR, HOOFS, HORNS AND OFFAL. 

 All these are valuable sources of nitrogen, and in some cases may 

 be economically and beneficially employed. They call for no 

 special mention and are nearly all old friends of the agricul- 

 turist. We append a list of sundry materials showing their ap- 

 proximate percentage in assimilable nitrogen, which may not be 

 without utility. 



Table showing the quantity of nitrogen, in pounds, contained in every 

 one hundred pounds of the following substances :
