on the spot by an ingenious artist. The tree delineated is a Beech of about eight-and-twenty feet high, with a stout stem, a beautiful top, and with roots more than twelve feet long; so that the whole is calculated to form a load of considerable weight. The mode of maintaining the balance, of bundling up the roots, of compressing and preserving the branches-as also the various functions of the steersman, the balancemen and their assistants-may all probably be better apprehended in this view of their united efforts than by any verbal description. The reader, however, may compare the two, as they will be found greatly to aid each other. It is easy to apprehend that, with a machine so constructed, the person stationed at the end of the pole possesses the same complete power over the direction of it as the steersman over that of a boat; but with this disadvantage on the side of the former, that the machine is far more difficult to manage than the boat in the water, owing to the greater unevenness of the surface of ground, and the extraordinary length of the pole, as compared with the rudder, thereby causing a much more sudden impulse to be communicated to the machine than to the boat. The steersman of the machine has, for that reason, a far more difficult part to perform, in which much judgment as well as strength is called forth, and where one assistant, and sometimes two or three, are requisite to aid him in so laborious a task. The above mode of balancing the tree between the axle, which is the centre of gravity, and the extremity of the pole, I greatly prefer, on every occasion where it can be adopted, to that of having recourse to the third wheel. This addition to the machine could seldom be made, with such extensive tops as the park-trees removed here usually have, without severe injury to the branches. But it will |
