Aspen Lumber Grades And Characteristics, Zigmond A. Zasada

Aspen Bibliography

While most hardwood and softwood lumber usually is graded, aspen lumber is not. On the contrary, it is usually sold by the sawmill to the wood manufacturing plant on a mill-run basis. Plants which saw aspen lumber for their own use rarely apply standard grades in sorting the lumber. They usually separate the "usable" from the "cull" lumber, basing their grade breakdown upon the minimum quality acceptable in their manufacturing process. Manufacturers who use only certain grades of aspen lumber, and who buy it on the open market, have been unable to locate sources from which graded aspen lumber is …

Logging Methods And Peeling Of Aspen, T. Schantz-Hansen

Aspen Bibliography

The logging of forest products is influenced by many factors, including the size of the trees, density of the stand, the soundness of the trees, size of the area logged, topography and soil, weather conditions, the degree of utilization, the skill of the logger and the equipment used, the distance from market, etc. Each of these factors influences not only the method of logging but also the costs. The purpose of this paper is not to cover in detail the effect of each of these variations, but to deal with some of the major problems typical to logging aspen. Well …

The Preservative Treatment Of Aspen, Frank H. Kaufert

Aspen Bibliography

Aspen is one of our least durable woods and is known to deteriorate or rot rapidly under conditions favoring decay. Records on aspen used under moist and severe decay conditions have shown that serious decay and failure of the product may develop in three to four years. Some present and potential uses for aspen involving conditions favorable to decay and in which this lack of natural durability is a factor are: (1) fence posts, (2) railroad cross ties, (3) mine timbers, (4) planking for secondary bridges, (5) sills and other construction members in buildings, (6) the lower logs of log …

Aspen Defiberization And Refining Of Product, Robert Craig Jr.

Aspen Bibliography

Because of the great demand for wood fiber and because there is an abundance of aspen available¹/ for this purpose, its conversion into a usable fiberized material offers possibilities. It also affords an outlet for low-quality bolts developed in any aspen logging operation or from land of poor quality.

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.

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 …

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.

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 …
