GARDEN MANAGEMENT. 



2184. The distance of these trees from each other must be determined by 

 their height, which has been given here for that purpose. None for perma- 

 nent effect should be planted nearer to each other than three times their esti- 

 mated height. This will afford breathing-room, and give tacilities for seeing 

 them. If the ground can be thrown into rough and uneven ridges, it will show 

 them to most advantage. Nothing can well look worse than the common 

 practice of placing each tree on the top 01 a little mound, raised on level 

 ground for that purpose. The tree looks as if it were keeping sentry over a 

 miniature potato-heap. The different classes should be planted in groups, 

 both for the sake of effect and to suit their varying heights ; spruces, larches, 

 Scotch firs, junipers, cedars, each having their own compartment in the pine- 

 tum. An arboretum is simply an extension of this idea, including all known 

 hardy trees. The same principles, in reference to distance, grouping, &c., will 

 also be applicable here. As sometimes the whole of the ground in either 

 is not moved previous to planting, very lai'ge holes will be necessary to secure 

 the well-being of the trees ; — from 8 to 10 feet in diameter, and from 3 to 4 

 feet deep, will not be too much for a Wellingtonia. If the soil can be well 

 trenched, mixed, and returned into the hole two or three months before 

 planting, so much the better.
