The poet may be right and in the spring the young man's fancy may lightly turn to thoughts ofLOVE, but it seriously turns to thoughts of BUILDING, and REPAIRING, andIMPROVING, and PAINTING, and that's where YOU get on, Mr. Lumber merchant.

MEXICAN TIMBER PINES FOR AMERICAN RAIL. WAY TIES

Interest in the commercial pines of the Sierra Madre region of Mexico as a possible source of timber for railway ties led the dendrologists of the Forest Service, United States Department of Agriculture, to examine recently a considerable number of specimens of the wood grown in that region, according to the statement of the Forest Service. These specimens were found to be allof the Pinus ponderosa atizonica, a form closely related to our western yellow pine. This variety has an extensive range in the Mexican provinces of Sonora and Chihuahua, and occurs in small arebs in the mountains of southern Arizona. If cut within our borders, the Arizona pine would probably be marketed with the true western yellow pine, from which the wood differs, however, in being heavier and harder.

Wood of the Mexican-grown timber bears a rather remarkable superficial resemblance to some grades of the longleaf pine of the Soulhern States. In order to determine for those particularly interested in the use of this timber for railway ties what are its comparative physical properties, arrangements are being made for the Forest Products Laboratory, at Madison, 'Wisconsin, to test short cross sections of the wood.

Windfall Losses On Old Cutting Areas

The sugar pine of California is very windfirm in its old age, but very susceptible to being blown over in its early youth, according to a study recently made by the Forest Service, United States Department of Agriculture. On the Sequoia National Forest, California, a plot of 160 acres was intensively studied where as a result of logging ten years ago 2,126 trees over 12 inches in diameter were left. Of these, 115 trees, or 5.4 per cent, lvere windthrown. fn general, the losses due to the blowing over of trees are greater in the larger diam.eter classes as the larger trees have a greater crown surface and are therefore more easily uprooted. Sugar pine appears to be the exception in the California forests. Of the trees noted in the study, the incense cedair suffered.the heaviest from wind, followed by w,estern yellow pine and white firwith sugar pine averaging as the most resistant of all.
