Both the subsoil and surface soil were of a red colour. The 
surface soil is a friable sandy loam ; the subsoil is stiffer, contains 
less sand, and more clav. 
Equal parts of soil and subsoil were employed in the experi- 
ment, and the liquid manure added to this mixed soil in the 
proportion of 7 of liquid to 2 of soil, as before. The liquid was 
left in contact with the soil for 3 days, and then filtered and 
treated in the same manner as the rest of the experiments. 
General, Composition of Liquid Manure left in contact with a fertile, friable, 
loamy Soil for three days.
