GARDENING FOR ALL. 19 
EARTH CLOSET MANURE 
naturally comes next to liquid manure, as being always 
existent where civilised human life issustained. Its value as 
a manure is variously estimated. In China it has for a long 
period been in common use, indeed very little of any other 
kind is used in Chinese gardens. Dr. Voelker places a 
manurial value upon it at the rate of g/- per head per annum ; 
Sir John Lawes estimates it at 8/10. 
Dr. Voelker gives the constituents as follows :— 
Pounds per annum of all ages. 
Total dry substance = 45°95. 
Mineral matter .. 10°34. 
Carbon 4 a2 16°85. 
Nitrogen Pe aa 794. 
Phosphate oe = 4°58. 
Notwithstanding such a low valuation, it is a very 
stimulating manure. Its effect upon the cabbage tribe, roses, 
and vines is very marked, but I do not recommend its use for 
potatoes, carrots, &c. 
Appended is a list of mixtures of chemical manures for 
various vegetables and fruit trees, and each mixture recom- 
mended is based upon the chemical analysis of the particular 
kind of plant to which it is to be applied. Each kind of 
plant or crop so manured will thus receive the kind of food 
most suitable for it, and, as a natural consequence, we shall 
have healthier plants and better crops in proportion as we 
wisely follow the most valuable information Dr. Griffiths has 
given. We must not do as two young farmers did a few 
years ago: They heard of Dr. Griffiths’s recommendation of 
of Sulphate of Iron for beans. He does not advise much 
more than 1 cwt. per acre to be applied; but they thought 
that quantity inadequate, and used it at the rate of 5 cwt. 
per acre to beans and wheat. The result was—no wheat 
and a damaged crop of beans! Other people make similar 
errors in the application of other chemical manures, and then 
condemn the manure instead of their own ignorance or 
foolishness. 
The chemical manures here recommended are intended 
to be used in conjunction with, or supplementary to, animal 
manures.
