Progress Report October, November, and December 1951 

SUMMARY 


Even though there has been a softening in the plywood and lumber markets 
during the quarter, there has been no slackening on the part of industry 
in its program of setting up a more secure raw material supply,. There 
has been no apparent decrease in prices either for logs or standing tim- 
ber. Generally, earnings for all wood-using industries have been good 
during the year. Many companies are interested and anxious to invest 
some of their earnings in new plants or equipment whereby they can better 
utilize their raw material. Sawmills and plywood plants have recently 
entered into contracts with pulp companies for the sale of chips from 
"mill waste.” However, many are interested in setting up some sort of 
a plant of their own so they can put this material into a product that 
will give them a greater return. 

Fiberboard plants appear to have good possibilities for the utilization 
of "mill waste." The cost of a board plant is much less than the cost 
of a pulp mill and board manufacture does not have the water and stream 
pollution problems encountered in the production of pulp. Also, mar- 
kets are very good which has created much interest and activity in this 
field. 

Members of the FUS unit have worked with both chambers of commerce and 
industry, furnishing them information that would be of value in setting 
up board plants. 

During the quarter the Weyerhaeuser Timber Company announced their plans 
to construct a board plant at Klamath Falls to utilize the defective 
white fir in the Klamath basin. One plywood company has made applica- 
tion for a certificate of necessity for a board plant which will utilize 
"waste" material from their present operation. 

Defense work during the past three months has been confined, chiefly, 
to work with the Bureau of Ships. Several boat companies have milit- 
ary contracts for the construction of mine sweepers. These companies 
have had little experience in the laminating of oak keels and have re- 
quested much help from the FUS unit in their problems with glues, 
assemblies, and curing schedules.

Reduction and Re cove ry of ’’Logging Waste 11 

The Westfall Engineering Company of Portland, Oregon have developed a 
pneumatic “tired yarding unit which is called "The Performer 0 11 This piece 
of equipment is creating considerable interest among loggers in the area. 
It is designed for the handling of large-size logs. Power is produced 
by 225 horsepower Cummins diesel motor. It is equipped with a bulldozer 
and an arch attached to the machine. The machine is mounted on four 
21 x 25 inch tires. It can be operated at all speeds from two to thirty 
miles per hour. Due to its speed it is of particular value in logging 
timber a considerable distance from roads. The machine is very expen- 
sive, costing $35,850 f.o.b. factory. However, the company claims it 
will do at least twice as much work as a D-8 Caterpillar equipped with 
an arch. 

Two of these machines are now in use and five are under construction. 
Matson was invited to watch this machine perform in the lot near the 
factory and he obtained the picture shown in Fig. 1. Apparently, a 
machine of this type but of much smaller design would have wide applica- 
tion in the midwest and southern forests. The company is interested in 
building a smaller model if it appears that there is a large enough mar- 
ket to justify it. 

Scaling and Grading of Logs 


A committee consisting of members of the Forest Service, the scaling 
bureaus of Washington, Oregon and northern California, and members of 
industry have been organized to work on scaling and grading problems 
of logs coming from the Douglas-fir region. The immediate problems of 
this committee are to try to work out one set of scaling and grading 
rules for the entire Douglas-fir region. At present we have five scal- 
ing and grading bureaus each having their own rules. Prior to the time 
they agree on one set of rules the committee will review any proposed 
changes of the individual scaling bureaus. 

Harland C. Hiatt of the Timber Management Division of the Regional 
Office is Chairman of this committee. The committee held its first 
meeting on December 10 and dismissed the proposed rules submitted by 
the Southern Oregon Scaling Bureau for ponderosa and sugar pine logs. 
The Forest Service has recommended a set of rules similar to the ones 
that were developed several years ago by the Experiment Station for 
ponderosa pine. 

Matson attended this meeting and explained the work the Forest Products 
Laboratory and the Station have been doing on log grade studies and 
lumber grade recovery studies. Members of the committee appeared to be 
interested In these studies and were anxious to receive copies of the 
Laboratory 3 s report on the studies made at the six plywood plants. 



2 - 




During the time the log grade studies were being made at the six ply- 
wood plants there was some indication that spiral grain might be 
correlated with long radius of the logs. At the request of the Lab- 
oratory we made r “.-' „id checks on this point. Careful measurements 
were made on twenty-five second-growth trees and twenty-five old- 
growth Douglas-fir, These data were submitted to the Laboratory and 
showed that there was little correlation between spiral grain and 
the degree of change of the long radius of the logs, We, also, found 
that spiral grain was more serious in old growth than in young growth 
and that the long radius seldom remains in the same plane throughout 
the length of the tree. Some additional field checks will be made 
and it is planned to prepare a report on this project that should be 
of some assistance in determining the grade of Douglas-fir logs. 

Lumber and Lumber Indu stry 

Most of the incense cedar growing in southern Oregon is very defect- 
ive and yields a large percentage of low grade lumber. We feel that 
this lumber would be suitable for crating lumber for military use and 
have made such recommendations to local Army Engineer Corps, 

Reduction of “Sawmill Waste " 

Pulp companies still are continuing with their program of obtaining 
a higher percentage of their raw material from ’’mill waste,” The 
present price of Douglas-fir chips at the sawmill is approximately 
$6,^0 per unit. Hemlock chips are much more in demand and the price 
per unit for this material is in the vicinity of $20 per unit, 

A few more hydraulic barkers are being installed in some of the larger 
sawmills so that they obtain bark-free "mill waste” that can go dir- 
ectly to the chipper. Many of the smaller mills are interested in 
this program but do not have sufficient production to warrant the 
costly installation of a hydraulic barker. There is considerable need 
for the development of a mechanical log barker that would be within 
the cost range of sawmills cutting 50" to 100-thousand board feet of 
lumber per day. 

With the present power shortage in this region there has been consid- 
erable thought given to the possibility of producing electric power 
in steam plants, using hogged fuel. At the instigation of Bonneville 
Power Administration a survey was made of the Roseburg area in Oregon 
and the Wenatchee area in Washington to determine how much hogged 
fuel could be obtained, within a reasonable hauling distance of these 
two cities. 

Seasoning of Lumber 

An inquiry was received from the Youngs Bay Lumber Company, Roseburg, 
Oregon about the handling of kiln dried wide flat grain kiln dried 
Douglas-fir, This company has an excellent battery of internal fan 


- 3 - 


kilns and uses particular care in the drying of Douglas -fir finish,. 
They were receiving complaints about the cupping and warping of such 
lumber after being planed and in storage both in their finish shed 
and in the retc ,,ards« A visit to their plant revealed that the 
company , for greater efficiency in handling,, had adopted a proced- 
ure of tying four pieces of finish into a bundle with twine. Further , 
they were mixing lengths in the same bundle . It appeared that the 
lumber which was dried to less than 10 -percent moisture content was 
permitted to reabsorb moisture freely on the uneven ends and on faces 
where bundles were separated by the thickness of the twine. Particu- 
lar undesirable effects noted were warping of the board ends, which 
extended beyond the pile and cupping of the outer boards of each 
bundle. The suggestion was made that in order to keep dry lumber 
flat and prevent serious change in shape it was desirable to sort 
lumber for length for piling and to avoid exposing one face freely 
to the air while the other was protected. Also, that the bundle- 
tying system they were using would, actually be expected to promote 
cupping. This company had. only recently had a representative in 
attendance at the dry kiln course in Corvallis and they, therefore, 
appreciated immediate changes which they would need to make in order 
to avoid their complaints. 

Veneer and Pl ywood 

New plywood plants continue to be built and come into production in 
the Douglas -fir area. Knauss visited a new plywood plant being con- 
structed by the Long-Bell Lumber Gompany at Gardiner, Oregon, which 
is being designed and built by George French (formerly on the staff 
at- the Forest Products Laboratory) and is expected to be in opera- 
tion about January 1, 1952. The Long-Bell Lumber Company have 
operated a plywood company at Weed, California for many years. This 
plant produced ponderosa pine plywood before the Douglas-fir region 
was producing any appreciable amount of plywood and today part of 
its production is of Douglas-fir shipped from outside the territory. 

Expansion of the Douglas -fir plywood industry was summarized recently 
by 0. Harry Schrader, Jr., of the Douglas Fir Plywood Association in 
an address at the Western Forestry Conference. H e stated that "today 
the Douglas -fir plywood industry is represented by 71 producing fac- 
tories operating under 61 separate ownerships. An additional l£- to 
20 -millions are under construction and expected in production before 
July 1, 1952. Approximately 3 I 4 veneer green ends are or have been 
in production recently, a few owned by operating plywood plants but 
most by industry. The industry, over-all, employes more than 12,000 
people in its manufacturing operations alone and the total annual 
value o.f fir plywood produced is in excess of one quarter of a billion 
dollars. Present annual productive capacity is estimated at 3.1- 
billion feet, 3 / 8 -inch thickness, which is the customary method of 
quoting production figures. Production for 1951 is expected to 
approximate 2 0 7-billion feeto o...oo.o....o Today the Douglas -fir ply- 
wood industry consumes on an annual basis more than one billion feet 
log scale— perhaps 5 percent of the total nation «s timber cut...... 


Recognizing that the industries 1 capacity by mid-1932 will approximate 
3 .5 -billion feet of plywood and that indications are that productive 
capacity is stabilized around this figure for several ye ars, it may 
be estimated that the annual log volume demand by the plywood indus- 
try, operating near its capacity, will be 1.3-billion feet." 

Glued and Laminated Products 


Knauss made an inspection in October of the glue joints in the Loon 
Lake bridge. This is a wood-arch bridge in which the arches and 
posts are made of glued laminated construction, using Douglas-fir 
pressure treated with Wolman salts. Representatives of Timber Struc- 
tures (the fabricators), the American Lumber and Treating Company 
(who furnished preservative treatment), the American Wood Preservers 
Association, and the West '-'oast Lumbermen's Association were present 
as observers during the inspection. Results of the inspection showed 
that the glue joints were maintaining a satisfactory condition. The 
wood has not been given any surface protective treatments; such as 
paint and there is some evidence of weather checking where the wood 
is exposed directly to sun and rain. The bridge has been in service 
for a total of four years. 

At the Weyerhaeuser Timber Company, Longview, Washington Blomquist, 
of the Forest Products Laboratory, visited the edge-gluing operation 
in which narrow strips of clear redcedar are being glued into wide 
boards for resawing into bevel siding. Resorcinol or acid-catalyzed 
phenol resin glue is being used and is cured by the application of 
hot plates. Narrow clear strips of Douglas-fir are being similarly 
glued into wide boards for use as shelving. 

An increasing number of requests are being received for assistance 
in the gluing of laminated boat parts— both white oak and fir for the 
construction of navy mine sweepers. Knauss has been called to two 
ship builders who have contracts for the building of mine sweepers 
and who are setting up to do their own laminating. He has also been 
called to two commercial laminators in the navy who have subcontracts 
for finishing laminated white oak frames for Douglas-fir stems, keels, 
and other parts for the mine sweepers. John Kuenzel, Bureau of Ships, 
Washington, D. C. and several other navy personnel were in the region 
during November and Knauss spent some time with them, calling at the 
laminating plants and testing laboratories. The Navy is urging the 
Forest Utilization Service to make themselves available in a major 
way for consultation in this field during the nexb few months. 

White oak lumber for laminating purposes is being imported from the 
southern part of the country and Douglas-fir is being obtained in 
this region. During the past year the revised working stresses 
applicable to the design with dry glued laminated Douglas-fir for 
structural timbers have found considerable acceptance on the part of 
designing engineers, particularly where they have been incorporated 
into building codes. The use of these higher working stresses has 


- 3 - 


permitted^ the laminators to design more economical structures so 
that laminated construction is rapidly replacing wood construction 
formerly designed in solid members which necessarily were of green 
wood,. One of tb- inmedia te effects of this improved situation is 
reflected in the following quotation taken from the "Trade Review" 
of November, issued by "The Timberman; " 

TIMBER COMPETING SUCCESSFULLY WITH STEEL, SAYS FULBRIGHT 

Structural timber construction is now competing success- 
fully with steel as a result of improved engineering, fabricat- 
ing and erecting techniques « This was reported this week by 
Ralph H» Fulbright, vice president and general sales manager 
of Timber Structures, Inc,, Portland, when he addressed the 
Portland Hoo-Hoo Club, Fulbright said that improvement in 
many techniques made In the past few years has resulted in 
timber construction competing with steel even though the 
price of lumber has increased five times since 19U0 as 
against an increase in the price of steel of two times in 
the same period* In I 9 I 4 .O, he stated, his firm bought select 
structural Douglas fir lumber for $2ij., 

Fulbright said that lumbermen should realize that, pound for 
pound, lumber is stronger than steel* Wood, he said, is the 
only structural material which can withstand successfully a 
100 percent impact overload,, 

Regarding the progress made by Timber Structures, Inc,, 

Fulbright said that the company in October has shipped ll|2 
carloads of _ fabricated structural lumber itemsj thus far this 
year the firm has shipped an average of 96 carloads each 
month. At the same time. Timber Structures, Inc, has received 
a monthly average of 100 carloads this year. In 195>1 up to 
November 15>, he said, the firm has shipped 19,000 roof trusses. 

If these trusses were pieced end to end they would stretch 
away for 7^0,000 feet. 

Inquiry was received from one of the laminators regarding the poten- 
tial use of Western hemlock in gluing structural wood members. 

Although the strength of Western hemlock is below that of Douglas-fir, 
which in western woods has been used almost exclusively for structural 
purposes, the relatively higher grade obtainable In Western hemlock 
and the increasing supply of this species has developed an interest 
in its potential supply for laminating purposes, 

R, F, Blomquist of the Forest Products Laboratory visited in the region 
in November and, accompanied by Knauss, visited Douglas-fir plywood 
plants and glue manufacturing companies. 

Utilization of Western Hardwoods 


The Associated Plywood Mill, I n c, have recently acquired timber hold- 
ings in southwestern Oregon on which Is located a rather extensive 

- 6 - 


stand of tanoak. The plywood company is experimenting with the con- 
version of tanoak into plywood and has invited the cooperation of the 
Oregon Forest Products Laboratory and the Forest Utilization Service, 
They recently rot'- :j cut several logs--some hot and some cold — at 
their Willamina Plywood plant and have also had some tanoak flitches 
sliced into veneer at the Olympic Manufacturing Company at Gresham, 
Oregon, They are producing samples of plywood from this veneer and 
will explore potential markets for the material. The logs which were 
cut into veneer were of high quality compared to the tanoak logs the 
FUS has seen previously and, when heated in accordance with the con- 
clusions reached by Laboratory tests at Madison several years ago, 
produced a high quality veneer. 

One of the reasons alder lumber has not been given wider use is be- 
cause it is considered— all the way from the stump through the sawmill 
—as an inferior species. The poorest type, of small sawmill usually 
cuts the lumber and it is badly manufactured. This lumber is ordin- 
arily not graded and the main incentive for the sawmill man is to cut 
the largest quantity rather than the best quality. Before this lumber 
can receive more favorable consideration by the furniture manufacturers, 
who are now the chief users of this lumber, it should be properly 
graded so there will be some sound basis for the buying and selling. 

The furniture manufacturers in the Los Angeles area have had difficulty 
in obtaining suitable alder from mills in this region. One lumber 
broker, Slattery Hardwood Company, who has been furnishing material 
for the Los Angeles plants, has decided to build his own sawmill. 

This mill will be located at ^aymond, Washington and will produce at 
the beginning about 15,000 board feet of lumber per day. This is a 
small mill for the Bouglas-fir region, however, it is larger than 
most alder mills and, no dotibt, will produce better manufactured lum- 
ber than is ordinarily available. 

The Station and Oregon Forest Products Laboratory have given consid- 
erable thought to the problems of grading both the logs and the lumber. 
The Oregon Forest Products Laboratory has recently started a project 
on both hardwood lumber and log grades. Immediate plans are to try 
to set up log grades for alder, using the grades developed by the 
Forest Products Laboratory for eastern and southern hardwoods as a 
base. The mill tests will be made and these rules will be adjusted 
to meet local conditions. If these rules work out satisfactorily for 
alder, a similar procedure will be followed for other local hardwoods. 

The FUS unit has worked with the Oregon Forest Products Laboratory 
on the utilization of western dogwood and madrone. With the present 
shortage of material for making shuttle blocks we felt that these 
two species might have possibilities. In our last quarterly report 
we requested other FUS units contact us if they knew of companies 
that might be interested in trying these western species. Englerth 
of the Southeastern Station notified us that the Steel Heddle Manu- 
facturing Company of Greenville, South Carolina were interested. We 
contacted the company and proposed that we send them a half cord of 


7 


each species to be collected by members of the Oregon Forest Products 
Laboratory. 

Wood Preservation 


The Forest Products Laboratory included Cascade west side locations 
in setting up field service records on treated poles in R.E.A. utility 
lines. Kulp and Hegge were in the Oregon area in October and inspected 
and set up a unit near Portland (Mt. Hood) area and in Roseburg. The 
units included full-length pressure treated Douglas-fir poles which 
had been in service from one to two years. Fig. 2. shows details of 
the inspection which included a record of the pole size and class, 
history of installation, increment boring to determine depth of pene- 
tration of preservatives, inspection of wood condition at ground 
level, and data on the soil type. It is anticipated that inspection 
of the line will be made at intervals of several years. These units 
are part of the nation-wide service record project in which the 
Forest Products Laboratory is cooperating with the R.E.A. 

A representative of Boliden Mining Company, Stockholm, Sweden visited 
the Pacific Northwest recently. Interested in promoting a new type 
of salt for wood preservation purposes. The preserving agents are 
calcium and zinc arsenate which in final form in the wood are claimed 
to be nonvolatile and non-leaching in water. The claim is made that 
the process operates at normal temperature without any requirement 
for heat. The process is represented as having been used in Sweden 
since 1936. We do not know whether any American companies have 
arranged for distribution rights in this country. 

Wood Hydrolysis 


During the first part of the quarter the wood hydrolysis plant at 
Springfield again started production on a small scale. The Hudson 
Bros, have obtained complete control of the plant and intend to 
produce alcohol. Matson visited the plant in October. At that time 
they were making a wood-sugar solution from one percolator. It was 
their intention to first fill up all storage space with this solution 
and then employ the small crew on the production of alcohol. It is 
intended that they will gradually increase the size of the crew and 
as fast as possible will bring the plant up to full production. 

Pulp and Paper 


There still Is considerable interest in the expansion of the pulp 
capacity in the region. During the quarter the FUS unit made re- 
ports for N.P.A. on tax amortization certificates submitted by 
two pulp companies. One of these was for an entire new plant that 
would utilize "waste" from several sawmills. 


8 - 


Fiberboard Manufacture 


Interest continues high in the production of fiberboard from unutilized 
material at sawmills and plywood plants. During the quarter one new 
plant started producing board, a plywood plant made application for 
certificate of necessity to construct a board plant to utilize "waste” 
from their plywood production, and the Weyerhaeuser Timber Company re- 
ported their plans to construct a board mill at Klamath Falls. 

White fir in the Klamath basin is very defective and of little value 
for lumber and, consequently, is poorly utilized. The Weyerhaeuser 
Company have made exhaustive tests and find this species gives them a 
superior board over Douglas-fir. Rot in the white fir does not hamper 
much except that it gives a darker color in the board. The company 
plans to log all the defective white fir and bring in material that is 
as much as 75 percent cull. A hydraulic barker is being installed at 
the Weyerhaeuser plant and logs of all species will be barked before 
going to the sawmill. "Mill waste” from other species can be utilized 
for board but this material is needed for fuel for the boiler plant. 

At Weyerhaeuser's Snoqualmie Falls plant there is under construction 
a "Silvacel” plant that will produce wood fiber products. The defiber- 
izing process at the plant will be identical to that used in the board 
plant at Klamath Falls. The wood fiber material has many uses for 
such products as molding compounds, fiber for oil-well-drilling muds, 
and manufacture of roofing felts. In addition, Weyerhaeuser Timber 
Company and a local battery separator plant have worked for the past 
three years on development of a molded battery separator. Although 
the process is still in the pilot plant stage, results of the work 
are sufficiently convincing for the separator company to announce that 
plans are going forward for the commercial production of two million 
battery separators from fiber per day. This volume would be suffic- 
ient to practically replace the present production of wooden battery 
separators. 

The new plant at Snoqualmie Falls will utilize bark -free material from 
the sawmill. The hydraulic barker has recently been installed on the 
mill pond and all logs will be barked before going to the headrig. 

Silvicultural Relations 


During Ben Paul's visit to the region this summer he and members of 
the FUS unit met with Mr. H. W. Eades of the Canadian Forest Products 
Laboratory to discuss problems the Canadian lumbermen are having with 
compression wood in hemlock shipped to remanufacturers in this country. 

At that time it was recommended that samples of. the problem material 
be shipped to the Forest Products Laboratory and that someone from the 
Canadian Forest Products Laboratory go to Madison to clear up any 
differences that might exist in Canada and here on the identification 
and seriousness of compression wood. We have been notified that samples 
have been sent to Madison and that the Laboratory has invited representa- 
tives of the Canadian Forest Products Laboratory to meet with them 
sometime this winter at the Madison Laboratory. 




This Station and the Oregon Forest Products Laboratory have a joint 
project to study the properties of second-growth Port Orford cedar. 
The supply of old-growth timber now used for battery separators is 
very limited and tests were needed to see if second-growth material 
would be suitable. A number of separators from young timber were 
made and shipped to Globe Union, Inc. to be given tests. Prelimin- 
ary tests show this second-growth material to be equal or superior 
to the old-growth Douglas-fir separators now used by the company. 

Cooperation with Other Federal and State Agencies, with Industry, 
and with Technical Organizations in all Phases of Mood Utilization 

Director Cowlin spent a week at the Forest Products Laboratory early 
in the quarter. He discussed work underway at the Laboratory — 
particularly, that of interest to the wood-using industry of the 
Pacific Northwest. 

Matson attended two meetings of the Oregon Forest Products Laboratory 
Advisory Committee. The chief subject under discussion at these 
meetings was setting up a policy for licensing patents developed by 
the Laboratory, At present no policy has been set up and there is 
considerable pressure by five companies to obtain licensing contracts 
for the Kurth bark-extraction process. A sample contract was drawn 
up and presented to the Oregon State Board of Forestry who have 
jurisdiction over these contracts. 

The Kurth patent was the first one obtained by the Oregon Forest Prod- 
ucts Laboratory and it covers the production of wax, tannins, and 
other extractives from bark. 

Matson attended a field trip with the Washington County Planning Com- 
mission. This trip covered the same route taken by the committee in 
1939 when they were trying to determine a policy for lands that did 
not appear to be suitable for agriculture. At that time they recom- 
mended that these lands be used for the growing of timber, which, no 
doubt, was a wise decision. Several ivoodlots and small timber hold- 
ings were visited and problems of growth and utilization of the young 
timber were discussed. 

We continue to get requests from N.P.A. for reports on wood-using 
companies that are expanding or building new plants. During the 
quarter this region reported on eight applications. This makes a 
total of fifty-three applications for the year — valued at approx- 
imately 114 j.-milli.on dollars. 

The Pacific Northwest Section of the Forest Products Research Society 
held its fall meeting at Long-view, Washington on November II 4 .. Matson 
and Knauss attended. The program of the meeting centered largely on 
the subject of hardboards, emphasizing the need for developing econom- 
ical standards to control and stabilize the properties of products as 
they will be put on the market. 


- 10 - 


The following foreigners visited members of the FUS unit and discussed 
problems of forest utilization during the quarter: 


Some of these men were escorted to various wood manufacturing plants 
in the region* 

Matson met twice with Ralph DeMoisy, Director of the Washington Instit- 
ute of Forest Products to better correlate projects of both agencies. 

Writing and Reviewing Articles on Wood Utilization, Giving Talks, Arrang- 
ing Meetings, etc. 

During the quarter Matson completed the lumber grade recovery studies 
made at the Kogap mill at Medford and the Cape Arago mill as Coos Bay. 
Rough draft copies of this report have been sent to all cooperating 
agencies for their review and comments. These two reports show that 
grades of lumber recovered in the Medford and Cape Arago areas is poorer 
than average for the Douglas-fir region. 

Knauss arranged for the program of the West Coast Dry Kiln Club at the 
St. Paul and Tacoma Lumber Company, Tacoma, Washington on November 3. 

This company has recently installed a battery of Moore internal overhead- 
fan dry kilns and has gone to extra effort to provide a kiln roof with 
high degree of insulation against heat loss. This company is installing 
a hydraulic barker at its sawmill in order that its "mill waste" (slabs, 
edgings) may be suitable for chipping for the pulp market. This im- 
proved utilization at the plant will leave less wood fiber for fuel 
and more attention is being paid to minimize the steam requirements 
of the dry kilns. The company is conducting tests on the amount of 
steam required to operate the dry kilns and sometime next year plans 
to make available to the dry kiln club the results of Its steam studies. 

An old battery of internal fan kilns (wood construction), which has 
reached the end of its structural usefulness, is being dismantled and 
replaced by a tile concrete construction and it will also be provided 
with a high insulated roof. This company is increasing its dry kiln 
capacity and is quite extensively drying common grades as well as 
clears. One of the speakers at the meeting was a representative of 
the Stetson-Ross Company who spoke on planing mill layouts suitable 
for machining kiln dried Douglas-fir lumber. 

A representative of the Laucks Laboratories, Inc., Seattle, Washing- 
ton spoke briefly on the use of the n Moisture Sentry." He described 
the instrument as being in use in two plants in the Pacific North- 
west, one in Los Angeles, and one In West Virginia. An installation 
is being planned in the planing mill of J. Neils Lumber Co., Klickitat, 
Washington in the near future.

Matson and Knauss of the FUS unit and Bates of the Regional Office 
reviewed Fobes' paper on "Wood Lost in Bucking." This paper shows 
the amount of material wasted by improper bucking of logs at the six 
plywood plants where the Laboratory made the veneer recovery studies. 
This report is being written at the request of the Washington Instit- 
ute of Forest Products. 

The report on the amount of "mill waste" that would be available for 
further manufacture in the Lakeview area of Oregon was completed. 

This report has been submitted to interested parties for review and 
comments.
