_ The author was also enabled to submit to examination specimens of the soil and 
subsoil from the fields on which the tea had been grown. Both soils were of a 
reddish colour and in fine powder, the subsoil, which was taken 1 foot 6 inches 
below the surface, being rather deeper in colour than the soil. A textural exami~- 
nation of the specimens was made according to the method as described in the 
author’s work on ‘Chemistry for Farmers,’ and gave the following result :—

‘The amount of nitrogen and alkalies in the subsoil, it will be perceived, exceeds 
that which was found in the surface-soil. This may be owing to the circumstance © 
that heavy rains (40 inches within four months) had fallen for some time before 
the specimens were taken. 
Another sample of Cachar tea, kindly forwarded to the author by Dr. Joseph 
Nelson, was also examined, chiefly for the purpose of ascertaining how far we could 
rely upon the determination of the amount of matters which are removed by heating 
tea with boiling water, as indicative of the presence in the tea of commerce of 
exhausted tea or of foreign leaves. SOR 
100 parts of the specimen were found to contain 4-963 parts of moisture, and the 
ash amounted to 5 parts. By treating the leaves with boiling water until exhausted
