without risk, while a smaller quantity, instead of pro- 

 ducing an effect upon it, will probably be retarded in its 

 fermentation, and will consequently remain in the state 

 in which it was placed in the ground. 



Manure from the stables is estimated by the load, and 

 can be purchased at fifty cents per load. The quantity 

 required on the park cannot be less than twenty-five 

 thousand loads, which, at the above-named price, will 

 make the total estimate of its cost, delivered, $12,500, to 

 which, add mixing, carting and spreading, $4,000 — mak- 

 ing total cost, $16,500. 



Trenching, or the operation of opening the land to a 

 greater depth than usual, by means of trench plows, 

 spades, or other proper instruments, is requisite under 

 certain circumstances, in order to prepare for manuring. 

 Trenching must be carried on in various ways according 

 to circumstances. The simplest way is by the spade. 

 Three feet is the depth for trees, two for ordinary pur- 

 poses. Trenching is servicable in dry weather, as the 

 heat rarely, if ever, affects the soil below a certain depth. 

 Care should be taken, however, in trenching, not to 

 throw a poorer over a richer soil ; as great damage has 

 been occasioned by such mistakes. Trenching costs 

 much at first, but ultimately pays. It has been known 

 to repay the labor as much as a thousand per cent. In 

 trenching the site of an old plantation, the ground should 

 be marked out in sections of about thirty feet in breadth. 

 Under these circumstances it is best that three men
