accessories, to disperse them with skill and effect, implies no

As single trees, in respect to site, are wholly unconnected 

 with one another, the pits for them are to be made separately. 

 For this purpose, the ground, supposing it to be tolerably rich 

 and deep, with a porous subsoil (that is, a subsoil of sand, 

 gravel, or rock, or combinations of them), is to be trenched 

 to the depth of nearly two feet ; which depth is six inches 

 more than common gardeners' trenching. The latter is 

 usually executed two spits deep, with two intermediate shov- 

 ellings ; but in the work in question, we should go down 

 between three and four spit?, without any shovellings. The 

 method last mentioned tends to increase pulverization, and 

 especially a more general intermixture of the different por- 

 tions of the soil, without increasing the expense of the work.* 

 For a pit of this description, two, or at most three cart-loads 

 of the proper compost, are sufficient (I mean single carts, 

 or carts drawn by one horse), if mixed according to the prin- 

 ciples above laid down. If the soil be sandy or gravelly, the 

 clay compost should be used ; if clayey, the sand compost ; 

 with the addition of one third-part of the peat, or general 

 compost, which, as said above, is applicable to all soils. 

 Should the soil be deep and loamy, the last mentioned is 

 probably the compost best suited to divide into parts the fiesh 

 mould brought up, and to excite a general chemical action 

 throughout the mass. 



In executing the trenching, if the pit be to stand for a 

 twelvemonth or more, before transplanting, the compost is to 

 be laid down in half-loads round the stake, which marks out 

 the site of the pit, and at such a distance, as not to obstruct 

 the workmen. The dimensions are then to be marked out 

 for middle-sized trees, of from five-and-twenty to eight-and- 

 t wonfy feet high, in a circular form, and at two " spades" and
