The proportions of inorganic matter that may be regarded as most important, are — In the 1st, 64-100 ; in the 2d, 95-100 ; in the 3d, 55-100 ; in the 4th, 85-100 lbs. If equal weights of cotton-wool and Indian corn be taken from the same area of land, the deterioration to the soil in inorganic prin- ciples should be nearly the same. The yam, if compared with either of these crops, would appear to rob the soil of a still heavier weight of saline matter, although it is noticeable that the propor- tion of phosphoric acid abstracted by it is considerably less, and that no portion of it is thus withdrawn in the condition of phosphate of potassa.
