Felling operations in heavy stand of hemlock, British Columbia Coast Region average stand for a number of acres is obtained in this way, and when a certain proportion of a "forty" or a quarter-sec- tion, or a square-mile section has been covered, the average is applied to the whole area. When the sample plot method is adopted, the sample plots are generally taken in Yz-acre circles, and located at regular intervals on the cruise lines. The strip method is more satisfactory, however, and is much more widely used. Methods of Field Work Differ The results of the work of the timber cruiser range from simple columns of figures giving the kinds and quantities of timber, to a fairly elaborate map with elevations marked, and cruise figures recorded directly on the map, accompanied by a written report. Methods of field work and form of present- ing results vary widely, according to the personal experience, character, and ability of the individual cruiser. The demands of timber owners, lumbermen, and loggers have led many cruisers into the habit of working on rather a wide margin. Often a man who has timber to sell, is, of course, eager to see as high a cruise as possible on his timber land. On the other hand, a lumberman who wants a report on tim- ber which he intends to buy and operate, demands a consider- able margin of safety and consequently thinks most highly of the cruiser who turns in a figure well below what he will cut off the tract when he operates. This has resulted in an uncertainty among timberman and investors as to the validity of cruise reports in general, because of extreme variations in reports on the .same tract, due to variability in standards and methods. What the cruising profession has lacked h engineering training, with its resulting standardization f>f methods. The forest engineer, who is the modern
