Notionol Home lmprovemenl Council Adds DFPA

Douglas Fir Plywood Association is the latest major addition to the growing membership roster of the National Home Improvement Council, according to an announcement by Council Executive Director Edgar V. Hall.

DFPA's advertising director, John Ritchie, was elected a m'ember of the NHIC Board of Directors at the Board's quarterly meeting in Chicago April 17th. The election. Hall said, results from a newly established policy in which all primary national members arl given an opportunity to have representation on the Board.

"Mr. Ritchie makes an unusually strong addition to our director group," Hall asserted, noting that Ritchie directs one of the industry's most ambitious national advertising programs. DFPA, among other efforts, sponsors the NBC television show, ,,David Brinkley's Journal."

'The decision of Douglas Fir Plywood Association to support and participate in the Council's program for the first time confirms the growing awareness throughout our industry that remodeling offers the best route to market expansion," Hall said. ,'It is one more gratifying indication also that the Council is clearly established as the central spokesman and promotional ,spearhead for all segments of the industry."

"Beql the Beetle" Bottle Plans Drown for Tohoe Tree Form

Fibreboard Paper Products Corporation in May announced plans to begin sanitation harvest operations at its Lake Tahoe Tree Farm "".""!. near Kings Beach and Brockway. A minor insect attack has been iiscovered in a small area of mature and over mature ponderosa pine timber stands, according to Paul E. Shively, Fibreboard's Chief Forester.

The area involverl is not large, Shively said, and about a million board feet of standing sawtimbir will be harvested in the sanitatio' operation. "We will bi moving to attempt to check the spread of the "it "k," Shively stated. "Removal of the infested trees will help the residual stands to remain vigorous and to provide successive tree crops."

"These outbreaks occur in nature from time to time and our timber management program is geared to meet such contingencies," Shively said. ;For instance, we h"ve been watching this general area since 1957 when it first 6"."-" evident that insects were present in epidemic proportions in the ad'jacent Crystal Bay area'"

' ifrit.fv was recently accompanicd on an inspection of the area by eniomologists Ralph Hall and George Downing, from the U' S' For..i S.tuii Region 5 office in San Francisco; Knox Marshall, chairma., of the cal-lifornia Pest control Action council and forest engineer, Western Pine Association; arld Fibreboard's Forest Superintendent from the Truckee headquarters, Robert Krohn'

"W" ft"i hoped that natural predators would take over or that a die-off would occur to reduce the threat to our timber here' However' the exceptionally dry conditions of the past few years have been favor.able to insect build-up so it has become necessary for us to provide the control measures," Shively said.

The chief insect villian has been identified as Dendroctonus .o-u.commonly known as the Western Pine Beetlewhich attacks mature and over mature ponderosa pine, but leaves more vigorous second growth timber alone' - trt._oLiist Ralph Hall explained that the western Pine Beetle spreads in a'patchwork fashioir. Eggs hatch jn a host tree' then as it " ir,...t goes th.ough the various stages of its life cycle, the adults leave the host tree as a brood, moving to another, where the cycle starts all over in a new host tree. Thousands of insects are involved in each flight.

"Each mature beetle will deposit from 50 to 60 eggs," Hall said. "The population build-up, and the effect on mature timber stands, become increasingly critical unless control measutes are taken quickly."

Signs of infestation show up quickly and can be recognized as the needles of individual trees turn from the lush green color to a rusty brown. Close examination of the tree itself presents what appears to be sawdust, or fine wood flour, clinging in the depressions of the bark covering.

Death to the tree results from girdling as the larvae literally eat their way around the tree in search of food. This action takes place in the vital cambium layer, which is the live, or growing layer between the heavyrcuter bark and the woody portion of the tree.

Another identification mark of an infested tree is characterized by holes in the outer bark covering which have the appearance of buckshot from a hunter's shot gun. These are caused by adult beetles boring out on their way to another host tree.

Only about 40 acres of F'ibreboard's Lake Tahoe Tree Farm is currently involved. The entomologist's report stated that many trees are not infested and will not have to be removed.

Top Aword Announced

The U. S. Department of Agriculture announced that its Distinguished Service Award will be given to the Forest Service's Institute of Forest Gcnetics at Berkeley and Placerville, Calif. The award to the unit is the Department's top honor.

The Department announcement cited the Institute "for pioneering the science of forest genetics and the production of pine hybrids leading to international recognition as a center for genetic improvenrent of the pines of the world."

Recognition of contributions to the research unit's work by 13 men and 2 w,omen of the s,taff will ,take place later this year at Placerville. Berkeley stafi members rvorking under Robert Z. Cal.lahar:: and. William C. Cumming are: Alfred R. Liddicoet, Emery F. KimM. Tichenor, and Richard H. Smith.

Placerville stafi members working under Francis I. Righter and William C. Cumming are: Alfred R. Liddecoet, Emery F. Kimbrough, Edwin J. Carpender, Carroll W. Busche, Clarence M. Blankensop, George S. Bronson, and Lucille A. Peterson.

The Institute of Forest Genetics was founded h 1925 by Seattle lumberman James G. Eddy as the Eddy Tree Breeding Station and was deeded to the United States government in 1935. Since then the Forest Service has operated the Institute as part of its forest tree improvement work, working ,primarily with pines. In recent years it has concentrated on western pine species and added studies of the genetics of fir trees to its program.

The Institute has produced from controlled breeding more than 80 difierent pine hybrid combinations. tsy perfecting new breeding techniques, it has developed and improved methods for artificial breeding arrd has demonstrated that mass production of hybrids is feasible. These techniques are beirrg used by public agencies and forest industries in the United States to produce hybrids with faster grot'th and greater resistance to pests than "wild" trees. Many foreign governments have sent research g'orkers to the Institute for training in forest tree breeding.

TECO Announces Avoilobility of l-Vz Story Frqme Design

Timber Engineering Company has announced the availability of a special design for a l-fu story frame providing clear span construction in homes. The design is one of over 200 the firm maintains itr its extensive files to assist architects, engineers and builders in the efficient use of engineered wood framing.

Specifying a span of 26'wrth a roof slope ol 10/12, TECO's design utilizes a spacing ol 24" on center. Total dead and live load on the floor is 45 pounds per square foot. Dcsign dead load on ceiling framing is 10 pounds per square foot. Special details showing stair well framing and rafter anchorage rvith Trip-L-Grip framing anchors are included in the design.

Used in all joints of the TECO frame are 2-%" TECO split rings in conjunction with f" bolts. The purpose of the rings is to provide a stronger, more efficient joint through distribution of stresses over a greater area. Generally speaking, one2-%!' TECO ring is equivalent in strength to frve rl" bolts or twenty lOd nails. In the assembly of the TECO frame, split rings are placed in conforming grooves made in adjoining members.

Lumber specified in the TECO design includes a combination of 8x8's, 2x6's and 2x4's. Cornplete lumber and hardware schedules are presented so that an esrtilmate of costs can be prepared quickly.

- A free copy of TECO's design can be obtained by writing Timber Engineering Company, 1619 Massachusetts Avenue, NW, Washington 6, D.C. Ask for TECO design No. 620.
