ARTIFICIAL ADAPTATIONS OF 
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. 33 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 
but little care. 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 
arch, 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 with the arbor-vitse, 
but the branches are not so pliable. It may be used to advantage 
for narrower and lower arches.
