T2 Review of Loudon's Gardener''s Magazine. 



cessary for the health of the plants, and particularly in situations of this 

 kind, where, under the most favorable circumstances, they will be much 

 confined. With regard to the choice of shrubs, I should introduce as 

 "•reat a variety of evergreens as possible, of those kinds which, from ob- 

 servation, I have seen to succeed ; an enumeration of which, including 

 also deciduous shrubs and flowers, would be very acceptable fjom any of 

 your correspondents who have had experience in the management of su- 

 burban gardens. Among the common evergreens that appear to flourish 

 in these situations, I have noticed the common and variegated hollies, 

 the common box tree, the Chinese arbor vitse, the Aucuha japonica, the 

 red cedar, the evergreen privet, and the giant ivy. The latter of these, 

 (the ivy) which grows luxuriantly in most situations, might not only be 

 used to cover walls and fences, but might be trained up in pyramids, or 

 any other form which taste might point out, by having a frame work 

 fixed in the ground for training" it to; and if jasmine, clematis, or some 

 other light climbers, were intermixed with the ivy, they would, I think, 

 give a relief, and, at the same time, add to its beauties during the sum- 

 mer months. As it respects deciduous trees and shrubs, I should make 

 use of the lightest and handsomest flowering kinds that would thrive, 

 and such as, by an occasional and judicious pruning, might be kept with- 

 in bounds. Decorations might also be introduced upon a limited scale, 

 consisting of ornamental vases and other tasteful designs." 



Very useful papers, but the plans annexed are too expen- 

 sive for our work. 



Article V, contains " simple and expeditious modes of as- 

 certaining the heights of trees ; by the Conductor, and 

 Richard Varden, Esq. These modes are illustrated with 

 engravings, which we shall endeavor to insert in a future 

 number. 



The following is a simple method, and answers very well 

 in the cases mentioned : — 



"Trees are either crowded together, or standing singly, or so as to he 

 clear from other trees on at least one side. In the former case, they are 

 best measured by sending up jointed rods, formed of deal, or any other 

 light wood. First one rod (say 5 feet, or 10 feet in length, and half an 

 inch in diameter) is pushed up the side of the trunk, and held there by 

 the left hand ; and a piece of tin tube, about 4 inches in length, and of 

 the same diameter in the clear, as the rod is put on the lower end of it 

 about two inches. One end of this tube being firm on the rod which is 

 held up alongside the trunk with the left hand, insert another rod in the 

 other end of the tube with the right hand, and so on, till you have push- 

 ed the jointed rod so formed to the top of the tree. Then take it down 

 and count the number of rods, &c., putting each piece of tin tube, as it 

 is taken off, in your pocket. This may seem a tedious operation ; but a 

 man and a boy, with fifteen rods, and fourteen pieces of tin tubing, will 

 measure more than one hundred trees in a day." 



Another method is as follows : — 



",The height of single trees may also be taken with expedition during 

 bright sunshine by their shadows. Set up a rod, say of six feet in height 

 above the surface, and measure its shadow ; then measure the tree's 

 shadow, and find the height by the Rule of Three." 



Among the reviews we find our Magazine very favorably 

 noticed, and numerous extracts made from our article of
