Mr. M. Macauley, of Portland, Oregon, de- scribes in the Columbia River and Oregon Timberman the manufacture of triangular rail- way ties as practised by the John O'Brien Lumber Company* of Somers, Mont. This company is located in a large belt of timber, principally tamarac, well adapted for the manufacture of railroad ties. This timber is tributary to the Whitefish, Stillwater and Flat- â head rivers. President Hill, of the Great Northern Rail- road, who is interested in the company, while in Austria several years ago, became inbued with the advantages of the triangular tie over the square tie, and has been using a consider- able number of these ties for several years in his system. The mill differs but little from the ordinary sawmill, the only difference being that in order to produce triangular ties the square timber is transferred to beveiled rolls and re-sawed. Advantages Claimed.âThe triangular tie requires less timber to serve the same purpose as the ordinary square tie. The ease with which the tie accommodates itself to the roadbed by reason of its V, or wedge-shaped, form, making it practically a self-tamping tie, at the same time offering a surface bearing on the rail equal to the square tie. It is contended that the triangular tie is more durable and less liable to rot in the track 7;^ 7*8- 7x8 . 7~*8' Ordinary Square Tie. than the square tie, by reason of its form pro- viding a natural watershed for the portion embedded in the track. This is obvious, there being a face of only three inches on each side before the acute angle of the tie is reached. On the square tie the water follows down the sides and lodges at the base, and every impact has a tendency to soften the ballast directly under the tie, and work loose the tamping, which is very noticeable at th
