ANALYSES OF THE CARROT. 57 



Composition of the leaves and stems, calculated without organic matter.

By this comparison, the actual differences between the leaves and stems are more dis- 

 tinctly seen. The organic matter is of no consequence, so far as the ash is concerned. It 

 is remarkable that the leaves contain so large a percentage of silica, and so little potash 

 in comparison with the stem. An analogous fact exists with respect to the potato vine. 



XXI. ORANGE CARROT. 



As only a few analyses have been as yet made of carrots, beets and other root crops, I 

 deem it expedient to place them in this connection, rather than devote to them a separate 

 chapter. 



The specimen analyzed was a large fine root eight or nine inches long, and one and a 

 half or two inches thick at the large end. It was of a bright salmon-color, and perfectly 

 sound. It was raised in the Hudson-river district, upon a sandy loam based upon the 

 Albany clay. Analyses of this soil have been given in the first volume, p. 260.
