These samples show the variations which have been noticed toward 

 the close of the past year in the composition of this valuable ash. 

 The results are reported at the present time to caution farmers. Cot- 

 ton Seed Hull Ashes ought to be sold only on the basis of a guaran- 

 teed composition. The sale of this article is at present, as far as our 

 supply is concerned, in the hands of a few parties in New York city,

Sent on from New York. W. A. Peters & Co. 



Number one was in a crystallized form, and number two in a fine 

 pulverized state. The latter has been of late Introduced into our 

 markets. The article deserves particular attention, on account of the 

 almostentire absence of chlorine ; and of the presence of a liberal amount 

 of sulphate of magnesia (from 33 to 35 percent, of kieserite), which 

 favors a rapid diffusion of the potash throughout the soil, besides 

 supplying an important additional article of plant food.
