Aspen Lumber For Building Purposes, Louis W. Rees

Aspen Bibliography

Recent shortages of lumber for building purposes make it desirable to seek out all possible supplies of additional lumber. Aspen, according to a study made in northern Minnesota during 1944, ¹/ may be a source of lumber largely untapped. The results of that study are the main basis of this paper.

Chemical Utilization Of Aspen, Geo J. Ritter, Ralph L. Hossfeld

Aspen Bibliography

Chemical utilization of raw materials depends largely on the chemical composition and the chemical and physical properties of the raw materials under consideration. The utilization of wood is no exception to this principle. Thus, a wood having a low percentage of cellulose is uneconomical as a source of wood sugar or pulp for paper; and one of an excessively knotty character is undesirable for chemical conversion Woods having several undesirable characteristics generally fall within the classification of species little used for the purpose. Fortunate! aspen falls outside this class.

Seasoning Of Aspen, Harvey H. Smith

Aspen Bibliography

Aspen is nor; the major forest type in the Lake States, and extensive stands are reaching maturity. Increasing quantities are being cut, and much is nor; being put to new and more exacting uses that require better air - seasoning and kiln-drying practices. The recent favorable market for green aspen lumber appears to be falling off, and the time may soon come when operators are no longer able to move green aspen. Such a change can be met by manufacturing better-quality aspen lumber and by carefully seasoning it to the desired moisture content to make it more acceptable. This report …

Machining And Related Properties Of Aspen, Edward M. Davis

Aspen Bibliography

Aspen occupies 20 million acres of Lake States timber land, or 39 percent of the total forest area. In 1945 there were 6 1/3 billion feet of aspen saw timber 9 inches d.b.h. and larger, and a larger cubic volume of smaller material. The cut of aspen lumber was 152 million board feet in 1946, and the forest could sustain a much larger annual cut.

Milling Of Aspen Into Lumber, C. J. Telford, F. B. Malcolm

Aspen Bibliography

In the manufacture of aspen lumber, the costs of stumpage and logging approximate 65 per cent of the total, and milling and sales 35 per cent. Milling efficiency is essential, but by itself it is not assurance of a profitable operation.

Aspen For Pulp And Paper, E. R. Schafer

Aspen Bibliography

Although the use of hardwoods for pulp and paper manufacture has increased considerably during recent years in the Lake States, the pulpwood consumed in this region consists largely of softwood species of which about one quarter is obtained from foreign sources. The wood resource, on the other hand, is comprised to a large extent of hardwoods, predominantly aspen, with the maples, oaks, and several other species available in lesser amounts. The present stand of aspen in the Lake States is estimated at nearly 20 million acres with a total volume of merchantable timber of about 32 1/2 million cords. The …

Aspen For Cabin Logs, Albert W. Sump

Aspen Bibliography

A plentiful supply of pine and cedar logs provided the early settlers of this country with a cheap and durable material for the construction of their homes and farm buildings. Only the axe and the ingenuity of the pioneer were needed to erect a shelter against the elements of nature. Early in the 19th century, the circular saw came into use resulting in a change in building construction. The pine stands in New England and in the Lake States, considered inexhaustible in the 19th century, were converted to lumber to construct buildings necessary for the rapid development of the country. …

Aspen For Core Stock, Arlie W. Toole

Aspen Bibliography

During recent years, aspen has been used in the Lake States region for a number of products. The war years in particular showed a marked increase in the use of aspen for pulpwood, box lumber, and many other wood products. The annual cut of aspen lumber in the region increased from approximately 67 million board feet in 1941 to 152 million board feet in 1946. In spite of this increased use, aspen still remains the only major tree species in the Lake States in which annual growth exceeds annual drain. It represents the major forest resource in this region that …

Mechanical Properties Of Aspen, R. P. A. Johnson

Aspen Bibliography

The clear wood of aspen has inherent properties of merit. Several of these properties are familiar to a large proportion of the general public, for some of the common types of matches are made of this wood. The requirements of wood for matches are exacting in that the wood must combine straightness of grain, ease of splitting, ease of working, and toughness To meet such rigid requirements, a wood must be suitable for other uses as well. The fact that aspen is not used more widely for other purposes lies not in the wood itself but in other factors, such …

Aspen For Containers, Waldo Sands

Aspen Bibliography

Aspen, because of its abundance in the Lake States, merits special consideration as to future management, utilization, and marketing. Although aspen lumber is used for many purposes, its chief use during the past decade has been for containers (boxes and crates). It gained its greatest prominence as container material during World War II.

Both producers and users of containers need general information as to availability and supply of aspen, its properties and usefulness for container material. With that in mind, this report on the use of aspen for containers has been prepared.

Aspen Availability And Supply, Clarence D. Chase

Aspen Bibliography

A knowledge of the total and available supply of aspen is basic to a study of the aspen situation. Hence, this paper aims to show the relative position of aspen²/ as a commercial forest type in the Lake States region, both currently and potentially. The data on areas, volumes, and growth are taken from the Forest Survey made in 1933-37, brought up to January 1, 1945, by office calculations including drain studies. Areas by site quality, allowable cut calculations, and volumes of timber available (1945 to I960) are the best estimates that can be made at this time.

Possibilities Of Managing Aspen, Paul Zehngraff

Aspen Bibliography

The management of aspen or popple (Populus tremuloides) has received little attention in the past, largely because of the former abundant supply of other and more valuable tree species in the Lake States. Be- cause of a rapidly expanding market for all forest products during the past decade, particularly during the war, the attention and ingenuity of industry have turned toward the use of aspen. As a consequence, aspen has now become one of the important pulpwood species in the Lake States, and is used for many other products. That it will retain its place for some time to come …

Aspen Properties And Uses, Zigmond A. Zasada

Aspen Bibliography

Because of the large demand for lumber during the last 10 years, and particularly during the war period, aspen has entered many new fields of use. At present there is widespread interest in the possibilities of building new industries and extending the life of old ones by increased use of aspen. Many people are interested in becoming familiar with this wood. This report has been prepared to give general information on the properties and present uses of aspen and also to help in correcting some of the existing erroneous ideas about this wood.
