ON THE MANAGEMENT 



serves wonderfully to meliorate and hasten their 

 dissolution. The influence of a summer's sun will 

 not be less beneficial, by exhaling their crude par- 

 ticles, and, by sweetening the parts, preparing them 

 the more immediately for vegetation. — Having 

 recommended so large a proportion of the dirt, or 

 scrapings, of hard roads and pavements, to enter 

 into the vineal compost, it may not be improper 

 to bring this material again under consideration. 



The dust, or dirt from roads, consists principally 

 of the following particulars : First, the soil of the 

 vicinity ; secondly, the dung and urine of horses 

 and other animals ; and thirdly, the materials of 

 the road itself when pulverized. Various other 

 matter may be brought by winds, and by other 

 means, but the foregoing may be deemed the prin- 

 cipal. The first of the above articles is brought to 

 roads by the wheels of carriages, and the legs of 

 horses and other animals ; the last is the worst 

 part of the materials, as the dust and scrapings 

 from roads, made and mended with soft stone that 

 grinds fast away, is much inferior in its vegetating 

 quality to that which is collected from hard roads. 

 On the whole, however, this ingredient of compost 

 from the roads is unquestionably in general of a 

 fertile nature, which may be attributed in part to 

 the dung, urine, and other rich materials of which 

 it is composed ; and, in part, to a kind of magnetic 

 power, impressed upon it by friction, and its per- 

 petual pulverization, s
