This report describes the characteristics of stadiums and seating in six North Central States; summarizes the purchasing methods for stadium seats; presents estimates of the present and future market; and points out the increasing competition to wood stadium seating form substitute materials.

Describes styles of hardwood-brick tile paneling; recommends production and installation methods, based on a 5-year test of 1,200 square feet of wood tile on various wall materials.

Many types of fences were found on residential lots in the metropolitan-suburban area of St. Louis County, Missouri, and three small towns in southern Illinois. Wire fences predominated. More wooden fences were found on village lots than on city lots. In general, the more expensive homes had the most wooden fencing. Homes over 5 years old had more fencing of all types than did the newer homes. Homes on large lots and those on corner lots had more wooden fences than homes on smaller lots and on interior lots. These relationships suggest that wood fence manufactures, wood material suppliers,...

A system of locating defects in a board by intersecting coordinate points was developed and a computer program devised that used these points to locate all possible clear areas in the board. The computer determined the yields by placing any given size or sizes of cuttings in these clear areas, and furthermore stated the type, location, and number of saw cuts. The computer improved on the manual act of extracting cuttings from a board. This was demonstrated conclusively in the yields obtained from a representative sample of 4/4 hard maple lumber in the FAS, Select, and No. 1 Common lumber...

Summarizes information on wood properties and uses of quaking aspen from recent literature. Includes current data on the growth and production of aspen in the Lake States. Outlines additional research needs concerning aspen wood properties and uses.

Describes a computer program, written in FORTRAN, which has been developed to assist in evaluating long-term forestry investments. A series of discount rates are used to calculate the internal rate of return and discounted costs, incomes, and net worth for any investments specified by the user. The features of the program are illustrated and discussed in detail, and all technical documentation is included.

The water-soluble amine salt was at least four times more effective than the oil-soluble ester. Concentration of the 2,4,5-T, spacing of the injections, and season of the year were also important; height of the spaced injections was not. The effects of these variables and of crown size and character of the branching on hardwood control with 2,4,5-T injections are discussed.

Summarizes recommended management practices for the shortleaf pine and oak-pine types in Missouri. Describes sites and soils, and silvical characteristics of pine; discusses rotations, cutting cycles, stocking levels, growing space requirements, and regeneration techniques; and prescribes treatments for stands with specified characteristics to maximize returns from pine management.

Black walnut (Juglans nigra L.) veneer specimens with wide variations in color were evaluated by a quantitative method of color measurement. The internationally adopted CIE system of colorimetry was used to analyze the data. These data were converted to also show them in the Munsell system. Color differences among the walnut veneer specimens were also numerically specified.

Describes procedures to follow and characteristics to consider in selecting superior yellow birch trees. The first selection should be on the basis of tree quality. Characteristics to consider are as follows: for the stem--straightness, roundness, taper grain, self-pruning, and absence of defects; for the crown--apical dominance, branch angle, and branch diameter; for growth--tree height, stem diameter and volume, length, diameter, and density of the crown, and growth rate.
