ANALYSES OF BEANS. 



283 



It appears from the foregoing analyses, that the ashes of the several varieties of bean 

 differ somewhat; the greatest deviation from the majority of them being in the Turtle- 

 soup bean. The ash varied somewhat in the degree of causticity, or in the amount of 

 carbonic acid. The ash, in each instance, was perfectly burned and white. There is a 

 great resemblance between the composition of the ash of beans and that of the cereals, 

 in respect to their richness in earths, alkalies and phosphates. 



The exhausting power of a crop of beans may be determined by the following calcula- 

 tions. A bushel of beans weighs about 60 lbs. There will be removed in every ten 

 bushels of beans :

Beans, although put upon what is regarded the barren soils, still make shift to supply 

 themselves with the richest and most valuable constituents of the soil ; and hence they 

 may be regarded as an exhausting crop. The plan of starving the bean is, after all, the 

 true mode of treating it , otherwise it would become strong and unpalatable.
