Home-grown Timbers

THE Forest Products Research Laboratory at Princes Risborough has recently issued a third edition (War Emergency Edition) of the “Handbook of Home Grown Timbers”(H.M. Stationery Office, 1941). This has become necessary owing to the greater demand being made on home resources due to a decrease of imports through the restriction of available shipping and an intensified demand. The edition includes information on a number of timbers not in general use, if not entirely unutilizable in peace-time, which can, it is stated, be satisfactorily employed for various useful purposes under wartime conditions. A notable addition, which the wholesale destruction caused by the German bomber has rendered advisable, is information on the fire-resisting properties of most of the species. These valuable data are the result of extensive experimental work carried out at the Laboratory. British grown timbers, we are told, as can be readily imagined, are now being employed in greater quantities and for very exacting purposes, and users are frequently at a loss to know how a particular species may best be utilized for some specified object for which imported timbers have been used in the past. It would be useful and interesting if a list could be made of the actual purposes throughout the country for which home-grown timbers are now being employed.

Beetle Pests of Furniture

UNDER the title of “Beetles Injurious to Timber and Furniture” a bulletin was issued in October last by the Department of Scientific and Industrial Research which gives an account of the damage and losses caused by these insects. It is based on the text of Bulletin 9 of the Forestry Commission by Prof. J. W. Munro, which is now out of print. The new bulletin, which is a revision and amplification of its predecessor, has been written by Dr. R. C. Fisher in consultation with Prof. Munro and includes the results of recent investigation. The longhorn and pinhole borers are essentially forest insects: they attack recently felled timber, but abandon it during the drying and seasoning. The powder-post and furniture beetles are enemies of seasoned woods, the former abounding in timber yards and the latter attacking antique furniture and the structural timbers of old buildings. The losses occasioned by these different classes of beetles are often very great, and the present bulletin gives a clear and well-illustrated account of how to avoid or reduce the damage by the adoption of preventive and remedial measures. The publication, which is Forest Products Research Bulletin No. 19, is obtainable from His Majesty's Stationery Office, or through any bookseller, price 1s. 6d. net.

Forest Products Research Board

THE report for 1938 of the Forest Products A Research Board recently issued (London: H.M. Stationery Office, 1939. Is. 6d.net) is dated June 1939. Remembering that the outbreak of war was to come so soon after its completion, there are one or two points which appear to merit particular mention. The chief, perhaps, is the research on composite wood, for which the Board had had under consideration detailed proposals for the provision of equipment.

Forest Products Research Board

THE report of the Forest Products Research Board for the year 1937 forms an introduction to the report of the Director of Forest Products Research at Princes Risborough for the same year (London: H. M. Stationery Office, 1938. 2s. net). The Research Board briefly reviews the work of the year and the measures laid down to be observed in future in the preparation of reports on mechanical tests of timbers; the grading of structural timbers; and plywood and other materials built up from wood. An extensive investigation into the latter and allied materials is proposed; a study being made of 'composite wood', that is, of industrial materials made of laminated or disintegrated wood. An investigation is also to be carried out into the possibility of producing from home-grown timbers charcoal for use in the chemical and other industries, a prominent manufacturing firm having made an offer of a grant towards the cost of this work. The Director in his report acknowledges the important direct help which the physicist and chemist can give to the various branches of the timber-using industry.

Timber Resources of the World

THE small handbook entitled “The Rationalization and Conservation of the Timber Resources of the World” (The Technical Press, Ltd., London. 2s. 6d. net), by Dr. A. Harold Unwin, is written mainly with reference to the amelioration of the 'Special Areas' and general improvement of woodlands. Dr. Unwin puts forward a series of proposals and suggestions of a somewhat varying nature. In the short period since the Great War, a number of organizations have come into being in connexion with forestry and timber utilization in Great Britain and the Empire. To mention but three, the Forestry Commission, the Forest Products Research Laboratory at Princes Risborough and the Imperial Forestry Institute at Oxford. The timber trade has also a considerable organization. Dr. Unwin wishes for a more rational care of trees and woodlands, especially in Great Britain, and for a better and organized utilization of the world's timber resources. Until recently, Dr. Unwin was conservator and head of the Forest Service in Cyprus, having previously served in Nigeria. Although there is much in the handbook of interest, the same cannot be said of the practicability of some of the proposals. The list of trees given at the end requires considerable revision, and would have been more serviceable had it included the botanical names.

Incidence of Attack by the Pin-hole Borer, Platypus cylindrus, F., in English Ash

Pin-hole borer damage to timber, caused by beetles of the families Scolytidae and Platypodidae, is associated chiefly with recently felled logs and occasionally with standing trees which are in an unhealthy condition. Information collected within recent years by the Forest Products Research Laboratory, Department of Scientific and Industrial Research, suggests that attack in standing trees may, however, be of more frequent occurrence than has been commonly supposed. In this connection, an interesting case of damage to English ash by the Platypodid beetle, Platypus cylindrus, F., is worthy of record.

Science and Building Exhibition

THE Science and Building Exhibition which is to be held on March 1-25 at the Building Centre, 158 New Bond Street, London, W.I, is being arranged at the invitation of the Building Centre, by the Department of Scientific and Industrial Research. The object of the Exhibition is to illustrate the work being carried out by the various organizations controlled by the Department, or associated with it, of interest to the building industry. The exhibit provided by the Building Research Station will deal with such subjects as concrete, plastering materials, fire resistance, bituminous materials and building units for walls and roofs, an exhibit by the Fuel Research Station illustrates work on domestic heating. The Forest Products Research Laboratory is dealing with wood preservation, dry rot, resistance of timber to abrasion, timber seasoning and insect damage. Interesting exhibits are being shown by the National Physical Laboratory on illumination in buildings, acoustics and engineering investigations such as wind pressure on structures and mechanical tests on structural steels, etc. The exhibit by the Water Pollution Research Board and the Department's Chemical Research Laboratory deals with water softening, the removal of dissolved salts from water and contamination of water by lead. British marbles will be dealt with in an exhibit provided by the Geological Survey of Great Britain. The Industrial Research Council of the British Iron and Steel Federation will show models of steel-frame buildings intended for working-class flats, and the applications of foamed slag as an aggregate for lightweight concrete. An exhibit by the Non-Ferrous Metals Research Association deals with galvanizing and zinc coatings, and recent investigations on the frost-bursting of water pipes. The Cast Iron Research Association, the Paint Research Association and the Rubber Research Association will also be represented. Lectures have also been arranged to take place at 8 p.m. on March 3, 10, 17 and 24.

Forest Products Research

THE report of the Forest Products Research Board for the year 1935 has been issued by the Department of Scientific and Industrial Research (London: H.M. Stationery Office, 1936). The report includes the report of the director of the Research Laboratory at Princes Risborough for the same year. The Board itself met only once during the year, when various pieces of research work under investigation were considered, as also the possibility of establishing a substation of the Laboratory in Scotland. The Board noted with appreciation that there was direct evidence of interest by industries concerned in the manufacture of both wooden and fibre-board boxes, as well as by users of such boxes, of the facilities now available in the new box-test ing laboratory. The investigations into the physical properties of timber which have a direct influence on its behaviour during seasoning and when in use have been advanced; and the results, it is considered, promise ultimately to be of material importance to architects and others engaged in industries dependent upon timber. As a result of visits to the Laboratory by many representatives of firms engaged in the manufacture of timber and timber goods, and instructors in building science or woodworking at various technical schools, some of whom have spent periods of varying lengths at the Laboratory, a new departure has been instituted. To minimize the interference with the routine work which such visits involved, a short educational course of one week's duration was given in September of which full advantage was taken.
