County, Town, and Village Forests 1743 is located in the northern foothills of the Alps and stretches along the Sihl River for a distance of nearly five miles. It may be reached from Zurich in about half an hour by rail or in two and one half hours by wagon. The Sihl valley has an approximate elevation of 1,600 feet above sea level. From the valley floor the wooded slopes rise rather steeply to the ridge-top elevation of nearly 3,000 feet. This is nonagricultural land, which would be comparatively unproductive were it not devoted to the growing of trees. In the Zurich city forest eighty-six percent of the trees are hardwoods—. Fig. 85.— The Zurich city forest beech, ash, maple, and elm. The remaining fourteen percent are conifers — pine, spruce, fir, and larch. The beech is the chief species. By the gradual removal of mature trees, the seedlings are given light and room in which to grow and to replace the old stand. The average tree of this forest is considered to be mature at ninety years of age; that is, it has reached its prime. The choicest trees are consequently allowed to attain this age; defective and inferior trees are removed earlier by means of thinnings. Formerly, the chief aim of this forest was to produce fuel— this was before the advent of the railroads — and to this day 64 per cent of the income is from fuel wood; the lumber produced brings only Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York State College of Agriculture; Cornell University.
