The vegetable matter is crenic acid, in combination with lime. 

 Soda was present in almost every instance where the test* was 

 applied. Chlorides and sulphates are the most abundant com- 

 pounds in the solution, excepting the crenic salts. At first view, 

 the quantity of soluble matter appears to be small, yet if any one 

 is disposed to go into a calculation of the quantity existing in an 

 acre, extending to the depth of one foot, it will be found to 

 amount to about twenty tons. But this is only about one-fifth or 

 sixth of the quantity of vegetable matter which, in the process 

 of time, will be converted into the food of plants, and which now 

 exists in an insoluble state. 



The soluble matter which we obtained from a field of G. Ged- 

 des, Esq., and which has been under cultivation for twenty-five 

 or thirty years, and has received no barn yard manure, was

The vegetable is in the state of crenic acid, in combination 

 with lime and magnesia. The remainder of the saline matter 

 consisted of the chlorides of sodium and lime, and carbonates of 

 lime and magnesia. A soil which had never been cultivated, and 

 treated in the same way, gave

The soil of the latter field was grown up to middling sized oak, 

 chestnut, hickory, maple, butternut and bass woods, and is very 

 frequently the case along the range upon which Mr. G's farm is 

 situated, the soil is not deep; the rock in a crumbling state may
