. Impressions of European forestry : letters written during a six months' visit to England and to the continent . Forests and forestry. origin of this custom dates back to the period of devastation in the sixteenth and seventeenth centuries. It was one of the provisions of the Forest Ordinance of 1669. That it has been on the whole a wise provision for France is well attested by the use to which certain of this reserved timber was put during the war. With- out this surplus it would have been difficult, if not impossible, to meet the demands of the French and the allied armies for the wood abso- lutely essential along the battle front. In practice the reserve may be effected in either of two ways: First, by the segregation of a definite portion of the forest and its man- agement apart from the general working plan for the forest; or second, by reducing by one- fourth the allowed annual, or periodic cut. In normal times the reserves also perform the use- ful function of stabilizing local markets and giving steady employment to resident laborers, for should it prove necessary for any reason to stop operations in the regular working groups, the workmen can be transferred to the reserved portion of the forest. by the experience of France. The lesson of the value of community forests is one that we as a nation have yet to learn. Some of the communes own and operate their own sawmills, but more often the mills belong to some individual. They are small affairs, often run by water wheels. The saw plays up and down vertically with a short stroke. They cannot be called speedy. After the sawyer has adjusted the log on the carriage, he sits down for lunch, or goes about other work. By the time he is through the saw has about reached the other end of the log. In one little mill in the Vosges mountains the rate of motion was approximately one foot in 30 seconds. The capacity of that mill was about one good sized tree per day, though the silver firs in the Vos- ges are good trees.
