_ The country around Delhi is remarkable for its great dryness; 
an if a line were to be drawn due west from the Jumna to the 
Indus, a distance of 400 miles, it would intersect no river, brook or 
spring, water being obtained only from wells. At Delhi these wells 
are generally about 35 feet deep; 40 or 50 miles to the westward 
the depth is from eighty to ninety feet; and beyond that distance 
to Hauri, 95 miles, it increases to 150 feet. Mr. Everest did not 
visit the country further to the west, but he believes that the wells 
havea depth of 150 feet or more. 
The soil consists of a granitic alluvium, but the surface is covered 
in many places with saline efflorescences similar to those which the 
floods of the Jumna now leave behind them.
