Our limits advise us to quit the principal building, or that appropriated to the panoramic view, especially as we cannot convey to the reader an indistinct notion of the curious stair-work, machinery, and carpentry of the ascents, &c. We were induced to ascend to the exterior, but the mid-day smoke of the town, and the heavy fog of the day, spoiled our view. Had it not been so, the numerous buildings below, with the gardens, &c. would have reminded us that much yet remained to be seen. We hastened down the staircase, as quickly as the loop-hole light would allow, (for this part is to be lit with gas,) and returned to the front court by the large door at which we entered. In the entrance-hall are two aloes in tubs, one of them of noble size, and we could not help contrasting this single triumph of Nature with the little world of art we had just been exploring; and our train of reflection was unbroken on our entering by the left-hand lodge-door, a range of arched conservatories, in the centre of one of which is a _Camellia Japonica_, which produces thirty varieties of flower, and is, perhaps, the most magnificent specimen in England. Already here are several rare and beautiful plants--a large proportion of exotics, and some of the most curious plants of this country's growth. In the centre of one of the chambers is a circular tank of water, surrounded by small _jets_, which are to raise their streams so as to form a round case of water, within which are to be aquatic plants, &c. At the end of this room aviaries are in preparation.
