As my instructions were to preserve as much as possible the belt and the trees in the interior of the ground already existing, I considered it most convenient to adopt the surrounding walk as a line of demarcation between the collection or arboretum in the interior of the grounds, and the miscellaneous assemblage in their circumference. Had the belt not existed, I should have extended the arboretum over the ground occupied by it, and thus have obtained room for a greater number of species, and a larger space for each individual tree and shrub. As things are, I have extended the belt in those places where it was wanting, and added to its interest by evergreen under-growths, such as rhododendron, kalmia, laurustinus, box, holly, and mahonia; by low trees, such as arbor vitï¾µ, red cedar, and cypress; and by large trees, such as cedar of Lebanon, silver fir, hemlock spruce, and evergreen oak. I have also introduced a collection of 100 different kinds of roses, all named; and placed the genera Ulmus, Quercus, Populus, and Salix in the new part of the belt, in order to give more room in the interior.
