PROCEEDINGS OF THE FARMERS' CLUB. 201 



There is often found in soils that are aluminous, ammonia, which goes 

 under the name of ammonial alum, and on analysis yielded soda and ammonia, 

 and also the sulphate of ammonia. There is another species found, called 

 soda alum, while other specimens are called manganese and magnesian 

 alum; it yielded alumina, magnesia, manganese, sulphur and water. These 

 last specimens, however, come from volcanic countries. The trap rocks of 

 New England are volcanic. 



We will subjoin here an analysis of the component parts of several kinds 

 of fruits ; but we will premise that many of the operations of nature are 

 carried on in a secret and comparatively mysterious manner; in other 

 words, the phosphate of lime is an ingredient universally found in nature 

 and most of the soils, bixt not in very large quantities at any one particular 

 locality.
