Sitka spruce is often planted as an ornamental tree in western Europe, and occasionally in the middle Atlantic states. The New England climate is too severe for it. ENGELMANN SPRUCE (_Picea engelmanni_) was named for Dr. George Engelmann. It has other names. In Utah it is called balsam, white spruce in Oregon, Colorado, Utah, and Idaho, mountain spruce in Montana, Arizona spruce farther south, while in Idaho it is sometimes known as white pine. That name is misleading, for Idaho has a species of white pine (_Pinus monticola_). In eastern markets the wood is known as western spruce; but that, also, is indefinite, for Sitka spruce is also a western species and is found in the same markets as Engelmann spruce. This tree’s range extends from Yukon territory to Arizona, fully 3,000 miles. It is a mountain species and is found in elevated ranges. In the southern part of its habitat it ascends mountains to heights of nearly 12,000 feet. It grows in the Cascade mountain ranges in Washington and Oregon. The species’ best development occurs in British Columbia. At its best, trees are 150 feet high and four or five in diameter; but every size less than that occurs in different parts of its range, down to a height of two or three feet for fully matured trees. Such are found on lofty and sterile mountains where frost occurs practically every night in summer, and winter snows bury all objects for months at a time. Though the stunted spruce trees may be only two or three feet high, their branches spread many feet, and lie flat on the rocks. Though such situations are exceedingly unfavorable to tree growth, the stunted spruces survive sometimes for two hundred years, and during that long period may not grow a trunk above five inches in diameter and four feet high. The Engelmann spruce is naturally a long-lived tree, and large trunks are 500 or 600 years old; and trees ordinarily cut for lumber are 300 or 400 years old. When the tree is young, its form is symmetrical, the longest branches being near the ground, the shortest near the top; but in crowded stands the trunk finally clears itself. Engelmann spruce lumber is usually full of small knots, each of which represents a limb which was shaded off as the tree advanced in age. The wood is lighter than white pine, and is the lightest of the spruces, the weight being 21.49 pounds per cubic foot. It is not strong, and it rates low in elasticity. The wood is pale yellow, tinged with red. The thick sapwood is hardly distinguishable from the heart. It would be difficult to compile a list of this tree’s uses, because in markets it hardly ever carries its right name. It is used for fuel and charcoal in the region of its growth; also as farm timber, and as props and lagging in mines. When it goes to market, it is manufactured into doors, window frames, sash, interior finish for houses, and for purposes along with other spruces. Large quantities of this wood will be accessible when lumbermen
