186 COTTON PLANTER'S MANUAL. 



In comparing the above table with that afforded by the 

 cotton wool, a marked dissimilarity presents itself. The ash 

 of the cotton seed is four-fold that of the fibre ; while the for- 

 mer has also treble the phosphoric acid possessed by the lat- 

 ter, as will the more clearly appear, when we present the 

 analysis under another form, corresponding with the second 

 table under cotton wool : 



Phosphoric Acid, . 



Lime, ...... 



Potassa, ...... 



Sulphuric Acid, ..... 



95-70 



From the foregoing analysis, it would appear difficult to 

 imagine a vegetable compound better adapted for fertilizing 

 land, than the cotton seed ; nor can we any longer be sur- 

 prised at the well' known fact, that soils long cropped with 

 this staple, without a return to them of the inorganic matters 

 withdrawn in the seed, become completely exhausted and un- 

 productive.
