GIANT ARBORVITAE 
Thuja plicata Don 
Giant arborvitae flourishes in rich, moist soil, and, as the name im- 
plies, the trees grow to great size. They frequently rise far above the 
surrounding forest, and their smooth columnar trunks, with pale, red- 
dish gray bark, ate very striking. The branches become pendent, from 
the weight of the fruit, and the little cones stand erect on the hang- 
ing twigs, presenting a very unusual effect. Both foliage and immatute 
fruit are rich green in colot. 
Giant atborvitae is found from Montana to California, extending 
northward to Alaska. 
The specimen sketched was obtained in the Columbia River Valley, 
thirty miles south of Golden, British Columbia, at an altitude of 
3,000 feet.
