with a color that cannot be improved-~what more can we say for 
a tree.^ Fig. 173 is a portrait of a full-grown hemlock in Studley 
Park, England. Fig. 174 suggests the general appearance of a 
well-grown hemlock at ten years after planting. Fig. 175 bears a

formerly growing on the edge of the rocky cliff below Niagara 
Falls. The three will give a fair idea of the varieties of form that 
hemlocks assume from youth to age. When quite young, how-

growth than any of these cuts indicate ; and for half a dozen years, 
by cutting back one-half the annual growth every spring, a richer

The hemlock loves a warm humid soil, and does not develop 
all its beauty in thin light sandy loams, where the white pine 
luxuriates. In a congenial soil the foliage is equally fine in sun or
