The larches, or "tamaracks" are confined to the cooler portions of the northern hemisphere, and are easily distinguished from other cone-bearing trees (1) by having their needle-like leaves arranged in clusters on the sides of short lateral branchlets, (2) by the falling of the leaves in autumn. Altogether, there are eight species of larch, three of which occur in North America, two in Europe and four in Asia. All have very straight and rather slender stems and slender branches and their wood is characterized by great strength, stiffness, hardness and durability. American Larch (Larix americana, Michaux; Larix lancina, Du Roi Koch) is also known as Eastern Larch, Black Larch, Red Larch, Tamarack, Hacmatac and "Juniper." This tree has a wide range of growth and adapts itself to a great variety of soil conditions. From Newfoundland its northern line of growth extends to Ungava Bay and Hudson Bay, westward to Coronation Gulf and Mackenzie Bay and along the eastern foothills of the Rockies to about latitude 53. Southward it extends to Pennsylvania, West Virginia, Wisconsin, Minnesota, Manitoba, Saskatchewan and northern Alberta. In moist, well-drained soils it is a rapid grower, but in muskegs and on the borders of swamps the growth is exceedingly slow. In northern Que- bec muskeg-grown trees measuring only two inches in diameter were frequently found to be 57 to 73 years old. This exceedingly slow growth produced a very hard and fine-textured wood which might possibly do for tool handles. On a measured area the number of these tiny trees averaged 12, 600 per acre; which, to the Liliputians described in Gulliver's Travels would appear as a dense forest of fair-si
