on the whole, than good pit-sand. It is plain, moreover, from the 
results of the foregoing experiments, that the use of sifted coal-ashes 
as an absorbent in place of dried earth in Moule’s earth-closet, which 
has been often recommended in this country, is judicious and praise- 
worthy from the chemical point of view. Ashes which by use in 
this way have become charged with nitrogenous constituents will 
undoubtedly be found useful as manure. Sifted ashes may be com- 
mended also, instead of loam, as-a fit material to mix with concen- 
trated or saline manures, such as ammonium or potassium salts, 
nitrate of soda, or Peruvian guano, before applying them to the land. 
With. the exception of the barley and oats in Series A, all the ex- 
periments thus far described were made with buckwheat. The results 
of other trials made with rye and with Indian corn, are set forth in 
the following tables. . 
Sixteen glass preserve-jars were charged with coal-ashes, such as 
were used in the experiments of Series D; 525 grammes of the ashes 
being placed in each jar. Three kernels of rye were planted in each 
jar on January 16, 1873, and the crops were harvested May 6; 
that is to say, the rye grew some seven weeks longer than the buck- 
wheat. The jars were exposed to the same conditions and watered 
with the same chemicals as the buckwheat plants of Series D.
