URINE. 146 



ammonia, and other parts will be absorbed in 

 the gaseous state by the charcoal and the ashes; 

 but all will at once be yielded up to the first 

 moisture, that may come in contact with the 

 heap ; and, therefore, it may be very properly 

 classed amongst those fertilizers which act as 

 a stimulus to the plant. We would, therefore, 

 reasoning from analogy, suggest the use of this 

 dried compost, as an excellent substitute for 

 bones in the drill in sowing turnips. And we 

 are farther confirmed in this opinion, from the 

 fact, that new manure, the urate, only lately 

 introduced, and which is presumed to be pre- 

 pared somewhat in this way, has been found 

 to answer admirably for the purpose intended. 

 The addition, however, of a phosphate of lime, 

 would increase its value in this respect, and 

 render it undoubtedly more valuable than 

 bones for this purpose. 



Another compost heap, which would answer 

 admirably for any purpose almost for which a 

 manure can be required ; that is, either as a 

 stimulant for turnips, as a pabulum for wheat, 

 or white crops — or, again, as a top dressing 

 for either of the above, or for grass, — may be 

 readily formed by mixing long stable litter, in 

 which decay has already commenced, with 

 the burnt ashes of vegetables or wood, in some- 

 what indefinite portions; taking care, how- 

 ever, that the litter should predominate, and 

 then pouring over the heap daily a portion of 

 the putrid urine, and stirring the mass well 

 up together. 



In this heap the ammonia of the urine 

 would be decomposed ; but the nitrogen, the
