SHOLO (from SHOrt Log) is a new solution to the old problem of profitably converting low-grade hardwood logs into products or product parts. It does away with the traditional and often uneconomical procedure of sawing low-grade logs into standard lumber and then converting this standard lumber into product parts. Instead, the SHOLO process is used to convert low-grade logs directly into product parts. In this report we describe the SHOLO process and give a specific example of one design of a SHOLO mill.

Indian tobacco (Lobelia inflata L.) is the source of an alkaloid (lobeline) that is used in anti-smoking preparations. Because of a brisk market demand for lobelia-and a decline in the harvesting of wild plants-we have studied how to grow this wild Appalachian annual as a row crop under cultivation. Our studies, begun in 1967, have continued through 1970. We have learned how to germinate the seed and grow young plants for setting out in the field, and how to care for them until harvest.

The hardwood flooring industry is losing a new and vigorous market by default. The mobile-home industry produced over 250 million square feet of single-family housing space last year, and very little of this floor space was covered with hardwood flooring. A preliminary glance at this situation seems to uncover an industry that offers many opportunities for hardwood flooring manufacturers. Why then is so little hardwood flooring being used? To learn more about this growing industry and to discover some of the factors that now limit the use of hardwood flooring, a series of discussions were...

Studying the response to thinning of a 7- to 9-year-old upland hardwood sapling stand, we found that height growth of yellow-poplar and oak trees was markedly reduced by heavy thinning. This suggests that stand density should be carefully controlled to achieve maximum benefit from thinnings in very young stands.

A paper presented at the spring meeting of the Northeastern Technical Division of The American Pulpwood Association, at Gorham, New Hampshire, 26 May 1970.

Past attempts to establish sugar maple (Acer saccharum Marsh.) by planting have generally met with little success. The failures have been blamed mainly on competition by other vegetation and on damage done by animals. Finding an effective way to establish sugar maple seedlings is a key part in the research being carried on in Vermont by the USDA Forest Service to develop superior sugar maples for producing sap and sugar.

This paper presents the joint distribution of diameter growth and length of clear stem for northern red oak (Querczls rzlbra L.). These data could be used in an actual tree-selection program for this species.

Pills of paraformaldehyde (trioxymethylene) are commonly used in tapholes in sugar maple trees (Acer saccharam Marsh.) to increase the yield of sap collected for making syrup and sugar. The explanation offered for this increase in sap yield is that microorganisms in the tapholes cause premature decline and stoppage of the sap flow, but that paraformaldehyde increases sap yield by inhibiting their growth. But what happens to the tree? To determine the effects of paraformaldehyde on the tissues surrounding tapholes, and on the microorganisms in those tissues, sugar maple trees were dissected...

Our study indicated that recreationists in Utah and New York prefer the same kind of forest landscapes--when the landscapes are depicted by 8- by 10-inch black-and white photographs.

In an effort to find a use for a large volume of the low-grade oak logs of Appalachia, we processed a sample of these logs in a typical southern-pine sheathing plant and determined the feasibility of converting them into construction grade plywood.
