The pomace made by the manufacturers of castor-oil 

 from the castor-bean, is said to be excellent for tobacco. 

 The scraps made by the tallow and lard triers have been 

 sought of late years for the same purpose, the price 

 being, we understand, about one cent a pound, or $20 a 

 ton. If in any tolerable state of preservation, it might 

 be good economy to first throw them to the pigs ; let 

 them consume such portions as they would, and compost 

 the rest with the contents of the pen, the whole to be 

 applied to the tobacco crop. Something might be thus 

 gained, in the way of food for the pigs, and the manurial 

 value of the scraps somewhat enhanced. But the culti- 

 vator of tobacco may safely conclude that almost any 

 thing which has been found favorable to general cultiva- 

 tion, will hardly fail to be favorable to this crop, and so 

 may be guided very much by circumstances. The wastes 

 from cities, villages, and manufactories may all be made 

 to supply the wants of the farm ; and the grower of 

 tobacco will, naturally, look around him, and see whence 

 he can purchase, with the least expense for transporta- 

 tion. 



Unleached wood-ashes, the spent ashes of soap-boilers, 

 the refuse of alkali works, the flocks from woolen facto- 

 ries, poudrette, night-soil, the horn and bone dust from 

 comb-makers, ground bones, almost any of the wastes 

 ofi'ered for agricultural purposes, may be profitably used 

 by cultivators near the places where they are produced 

 and sold cheaply as wastes. Gas lime would be good, 

 if spread on the ground the previous autumn and left 

 exposed till the time for spring plowing ; and green 

 sand marl would be profitable on most soils, so situated
