ON FARM GARDENING. 13 
be effective, and, hence, should be used regularly upon the 
fresh manure. 
Kainit, which is a low-grade sulphate of potash, checks 
fermentation, and hence prevents loss of ammonia. It con- 
tains much salt, and attracts and holds moisture. It should 
not be used under the feet of animals. 
Acid phosphate contains much gypsum, and unites with 
ammonia that would otherwise escape. 
The Geneva (N. Y.) Station recommends the use of one

The advantage of using kainit and acid phosphate are that 
they add potash and phosphoric acid respectively, in which 
barnyard manure is likely to be deficient. In some soils the 
potash will be preferable; in others, phosphoric acid will do 
more good. 
Value of Manure of Each Kind of Animal. — It has 
been figured out that the average value of horse manure per 
year is $27 per animal; cattle, $19; hogs, $12; and sheep, $2. 
But these are not the only sources of manure on the farm. 
The hen-house will annually yield manure to the value of 
25 to 50 cents per fowl, if intelligently cared for. The out- 
house will produce fertility to the amount of $10 to $50 per 
year, according to the size of the family, the precautions as 
to loss by leaching, and the care given. The kitchen slops, 
including the scraps, are worth $10 to $25 per year, if prop- 
erly composted. The wood ashes have a distinct and high 
fertilizing value; but not in the hen-house, where they are 
worse than wasted. And even coal ashes can be turned to 
account.
