Pulpwood production reached a peak of 4,280,000 cords in 1966 in the Lake States, 17% above the previous record cut in 1964. This paper shows pulpwood production for 1966 by county and species for each of the Lake States and compares production by species and Forest Survey District for several previous years. Also presented are data on 1966 pulpwood production and receipts by state for Illinois, Indiana, Iowa, and Missouri.

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.
