RECOGNITION OF TREES IN 1912-1913 The foJlowing characteristics will be helpful in recognizing the trees that are to be studied this year: Spruce, fir, and tamarack.— Norway spruce, which is not native to this country but is extensively planted as an ornamental tree in parks and on lawns, grows to a height of 70 to 80 feet and can be distinguished from the firs, which it resembles closely, by its four- sided needles and by its long, light brownish yellow cones. The needles of the balsam fir are flat and have 'JJll a light gray streak on the underside. The cone is dark '"^'"'' purple when young, turning dark brown after it is fully ripe and has shed its seeds. The bark of the spruce is a reddish giay in color, while the bark of the balsam fir is a light gray and frequently has small blisters on it which con- tain the fluid resin, used in the arts under the name of Canada balsam. The larch tree, or tamarack, can be distinguished from the spruce and fir by its needle-like leaves, which grow in clusters of ten or more and which fall off at the end of the growing season just as do the leaves of the broad-leaved trees. In the summer time the tamarack has a sparse, fringe-like foliage that gives very little shade. Flowers of the tamarack.— About the time that the leaves are coming out, in early May, the flowers of the tamarack are very beautiful and are worthy of close inspection. The male, or staminate, flowers have many yellowish anthers on short stalks, arranged spirally. The female, or pistillate, flowers are composed of many rose-red scales, also arranged spirally, and are accompanied by rose-colored bracts with long green tips. When the cones are present on the tree they give it a warmth of color that ha
