ash above given, and the same holds good of soda. 

 Chloride of sodium is common salt, and exists in a 

 small quantity. Salt is beginning to be much used 

 as a fertilizer on wheat-lands in Western New York,

The following may be accepted as about the 

 average composition of the ash of wheat- straw. It 

 is " Specimen No. 40" in the tables of Professor 

 Way, and I reproduce verbatim all that is said upon 

 the subject. (Soil sandy ; subsoil, stone and clay ; 

 geological formation, silurian ; drained ; eight years 

 in tillage ; crop after carrots, 20 tons per acre ; 

 tilled, December 1845; heavy crop ; mown, August 

 12th ; carried, August 20th ; estimated yield, 42 

 bushels per acre ; straw long, grain good, weight 

 62 Ibs. to the bushel.) Length of straw 42 inches.
