Forest Products Research

Abstract

THE annual report of the Forest Products Research Board with the report of the Director of the Forest Products Research Laboratory, Princes Risborough, for the year 1933 has recently been published (London: H.M. Stationery Office. 1934). In a general statement, the Director notes that the progress of timber research has been satisfactory, whether regarded from the point of view of the actual results achieved or from the value of the results when applied in the timber-using industries and professions. Sir Ralph Pearson retired from the post of director during the year, and Mr. W. A. Robertson, late of the Indian Forest Service, was appointed. The report states that there is evidence of the increasing interest taken by industry in the activities of the Laboratory. The work carried out during the year on seasoning of timber, both kiln and air-seasoning, on steam bending, the structure and mechanical strength of wood and on preservation, is summarised. As a result of investigation work, it is stated that “there is no material difference between old and new timbers from the point of view of shrinkage and expansion”, thereby disproving a common belief. Investigations were carried on in connexion with dry rot and insect damage. Tests were also carried out on the cricket bat willow.
