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 clay. 



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.
