IN matters pertaining to forestry, both the preservation of existing woodlands and reafforestation, the various States comprised in the United States of America hold varying positions and outlooks. Some are unquestionably facing the question in the spirit which its undoubted economic importance to the nation and to the individual States requires. The State of Illinois affords a striking illustration. A recent Bulletin (vol. 17, article 2, 1927) issued by the State Department of Registration and Education, Division of Natural History Survey, is entitled “A Manual of Woodlot Management,” by C. J. Telford. This manual is addressed to those landowners who have woodlots (i.e. woodland areas) or idle land. “It is assumed,” says the author, “that they appreciate the intangible benefits accruing from the woodlot as a refuge for wild life, as a local modifier of dry and cold winds, as a protection to the sources of local water supply, as a means of enhancing the beauty of the landscape, and as a place for recreation; and that they also appreciate the service to the nation rendered by productive forests.” These are large assumptions upon which to base a manual of forestry, and the past history of most countries has shown but too often that, taken collectively, such an assumption has not been borne out by the reality. This being said, it will not be the author's fault if the landowners of Illinois do not realise some of the benefits which the application of the recommendations of this manual place it within their power to achieve.
