The drawings [figs. 39 and 40] represent the view from the house, as it appeared before and after the improvement; upon the slide [fig. 39] are shewn five rods or poles, all of which are supposed to be ten feet high, and placed at different distances from the eye; these shew the difference in the apparent height of the same object in the different situations, and, of course, what may be expected from trees planted of any given size at each place: from hence, it is evident, that a young tree at No. 1, will hide nothing for many years except the park wall. A tree of the same size at No. 2, will do little more: this is confirmed, also, by the large trees already growing there; but at No. 3, where a heap of earth has been thrown up to a considerable height, a tree of twenty feet would hide most of the houses; and in like manner at No. 4 and No. 5, immediate effects may be produced, by judiciously planting, to shew the distant objects over or under the branches of trees in the foreground. Although, from the nature of this work, it is difficult to preserve any connecting series of arrangement, yet it may not be improper, in this place, to mention a few remarkable instances of removing earth and altering the shape of the surface of ground, especially as there is no part of my profession attended with so much expense, or more frequently objected to, because so often mismanaged.
