ARTIFICIAL ADAPTATIOXS OF 



but little care. 



they are firmly intertwined at the top, which is usually in about two 

 years' growth, the clipping of the sides and tops can be going on 

 to bring the arch to a form like that of 

 Fig. 32, or to any similar design the 

 proprietor may desire. An arch like the 

 latter figure may be brought to considera- 

 ble perfection in the course of ten years. 

 Fig. ^3 shows the probable appearance 

 that a hemlock archway would present in 

 twenty years after planting, supposing 

 the trees were allowed to develop 

 more naturally after their artificial char- 

 acter was well established. Such arches 

 increase in quaint beauty as they grow 

 old, and after the first ten years will need 

 Fig. 34, as we have already mentioned in 

 Chapter VI, is intended to show another effect, which may be 

 produced with the same side trees, by joining and twisting 

 together two side branches to form the arch, leaving the main 

 stems to form two spiry sides, and trim- 

 ming to produce this form. Another mode 

 that, if well executed, would produce a curi- 

 ous effect, is to unite the main stems as in 

 the first mode, but instead of twisting 

 them to grow vertically over the middle 

 of the gate, the twist should be made hori- 

 zontally, so that the tops would project 

 sideways, as shown farther on for elm- 

 tree arches. This in time would develop 

 into a wide crescent, inverted over the 

 irch, or it might be likened to a pair of 

 huge horns guarding the arch. The variety 

 of novel forms that such trees can be made to assume after ten 

 or twelve years' growth will surprise most persons. The same 

 kind of arches on a smaller scale can be made vyith the arbor-vitae, 

 but the branches are not so pliable. It may be used to advantage 

 for narrower and lower arches.
