Ne* Weyerh.erser Bark Plant Manulactures Valuable Products at Longview

Commercial quantity production of five products mantlfactured from bark has started in a recently completed processing plant at Longview, Washington, it was announced today by the Weyerhaeuser Timber Company..

This operation, tapping a new source of raw materials, is a significant step toward complete utilization of forest resources. Bark, long considered almost worthless in logging, represents approximately l2/o ol a sarv 1og. Under the Weyerhaeuser processes, bark now yields these main components:

Cork flakes, short fibers, tissue powder, a cork-fiber combination and a cork-fiber-powdgr combination. These materials have been proved valuable for a variety of uses, especially in the plywood glde,'plastics, insecticide and soil conditioning fields.

Processes which separate the bark ingredients were perfected by the Weyerhaeuser Development Department, set up in Longview in 1942. Only the thick bark of Douglas fir, predominant in Weyerhaeuser tree farm lands, is used in the ner,r' plant. Barks of all Pacific Coast conifers are usable, but, differing chemically and physically, they must be processed separately.

The bark products are being marketed nationally under (Continued on Page 6)

Insulating Board Products

oRE than half a century of Simpson manufacturing skill in the wood products industry, plus a constant laboratory search for better building materials, has resulted in the development of improved insulating board products. Made from the long and tough fiber of the matchless Douglas fir, the new Simpson Insulating Board Products have the advantage of greater structural strength and better insulating properties.

Outer side ot' the insulating building board is rnade in a new and attractiae topestry-like surface, finished in oyster-white.

Our new plant is working three shifts a day-but we can't make enough Simpson Insulating Board Products to go around yet .. . so discuss your future needs with your Simpson distributor.

New Weyerha euser Bark Plant

(Continued from Page 4) the general trade name, Silvacon, by the Weyerhaeuser Timber Company. Salesmen now are working in the Eastern Seaboard, Mid-West, California, and Pacific Northwest areas. In addition to the operations at Longview, the Silvacon products are being warehoused and distributed by company branches at St. Paul, Minn., and Newark, N. J.

Experimental amounts of Silvacon has been produced for several years in pilot plants. A series of grinding and screening steps convert the bark into the five Silvacon products, according to Clark C. Heritage, Technical Director, Weyerhaeuser Timber Company. Complete details of the processing will be made available at a later date.

Machinery extends to the very top of the new plant, which is equivalent in height to a four-story building. It covers 7000 square feet of floor space.

Bark reaches the plant's upper level by conveyor and travels downward through processing equipment to a separate ground-level bagging station for each product.

Maximum capacity of the Silvacon plant, on a threeshift basis, is approximately 75,000 pounds a day-enough to fill ll freight cars, according to J. T. Rushton, general superintendent of Silvacon production.

Weyerhaeuser will sell most of the Silvacon output as raw materials to manufacturers and distributors, but plans to package certain consumer products. Among them is Topper, a soil conditioner composed of cork-like flakes. Other consumer items still are undergoing exhaustive tests.

The Silvacon sales department is directed by R. D. Pauley, who is manager of the Development Department at Longview.

"Our 'company r,vill give practical assistance to anyone wishing to use Silvacon experimentally," Pauley said. Many companies and organizations already have assisted Weyerhaeuser in Silvacon use and consumer testing, he pointed out.

In explaining the latest utilization development of his department, Heritage gives much credit to the findings of many firms, groups and laboratories which for years have sought improved bark utilization. Considerable such progress was made by various Weyerhaeuser units.

Silvacon products are uniform in quality, predominantly brorvn in color, odorless and tasteless. Other information :

Cork-Known as Silvacon No. 383, this product consists predominantly of flake-like particles of cork ranging upward to rl inch in size. It is similar to commercial cork in most physical properties and contains'many highly reactive components; represents 20/o of. total production.

Fiber-Known as Silvacon No. 508, this product consists of stiff fibers, the hard tissue of tree bark, commonly described as bast fibers. The purity of this material and character of its fiber structure adapts it for use as a reinforcing filler in the manufacture of hard, high density products. It improves strength properties and minimizes ,shrinkage. Silvacon No. 508 is 10/o of production.

Powder--Known as Silvacon No. 490, this product consists of very finely powdered amorphoirs particles obtained primarily from the highly friable parenchymous tissue of bark. It is reactive toward alkali and various other chemical reag'ents, and its pl-rysical state allows it to be free-flowing and non-bridging. Silvacon No. 490 t"pi"sents lo/o of production.

Cork-fiber combination-(novn as Silvacon No. 412, this product is a physical combination of two of the basic constituents of tree bark, cork and lignified fibers. The particles of cork, similar in all respects to No. 383, except that they are smaller, blend with the stifi fibers, similar to No. 508, resulting in a product that is unique in many respects. In Silvacon No. 412, the properties of the individual components are put in combination for additional uses. No. 412 represents l5/o ol production.

Cork-fiber-powder combinationKnown as Silvacon No. 472, this product is a physical combination of three basic constituents of tree bark, cork, lignified fiber and powder. The cork particles are similar to No. 383, except that they are smaller in size; the stiff fibers are similar to No. 508, and the powder is similar to No. 490. These put the properties of the individual 'components in combination to form another unique product, adding to Silvacon uses. No, 472 represents 45/o ol production.

There are just two aristocracies in this world: the aristocracy of intellect, founded by God, and the aristocracy of wealth, founded by fools. Sir Thomas Overbury once wisely remarked that: "The man who has nothing to boast about but his illustrious ancestors, is like a potato-the only good thing about him, is underground."

It was Damon Runyon who, taking note of the oft-quoted Biblical statement to the effect that the race is not always to the swift, nor the battle to the strong, remarked that it might be so, but in his opinion that was the way to bet your money.

And some wag, discussing the presenqfprice of beef steak, suggested that the cow must have jurfped over the moon again.''

And another joker remarks that the cost of living has hit bottom; that is, if you can live on ball-point pens, alone.

While more and more frequently we hear repeated the question : "Is the present period 'postwar' or 'prewar'?"

Many friendly letters l".J ""]r,"g to this department. Most of them praise the spirit of optimism and good cheer that pervades these Vagabond columns, and did even through the trying years of war. We must admit there have been long stretches of time with the German War.Lords riding high that it was no easy task to write in optimistic, to say nothing of happy vein.

*{<* fn those days we used to tell ourselves that some day the war would be over and peace would once again spread her white wings over the earth and then it would be easy again to think happy thoughts and translate them into optimistic words. What a bum prediction that was !

Worlds of thinking n.oju ;.;or" deeply fearfut for the {ate of freedom today than they were then; more inclined to shudder at the shadow of the horrid Russian Bear than they were at the screaming of the mad little house-painter.

**{<

Today there hangs over us the constant mention of a possible World War Three; the blackness and mystery of the atomic threat; and the heavy load of debt, and doubt, and ,dread, and world hunger. And so many of the things that 'worry us don't even make sense. **!k

For instance: before me is the front page of a morning newspaper. Side by side are two articles of news. One of them warns this nation of gasoline and oil shortage and announces rationing in various states. The other article states that 12 huge Russian tankers are loading gasoline and oil for Russia, at tne Western port. And inside the leading editorial heading reads: "Russia deliberately blocks return of world peace." Honest,*now, is it strange people worry?

To the lay mind, such things fail to make sense. It would seem so easy to announce to the worldr and all men and governments therein that the United States will neither give, loan, trade, nor sell va,luable goods EXCEPT TO PEACEFUL NATIONS that are openly striving for world peace. f g[ess that's too practical a thought. I offer it as a resolution, notwithstanding.

The newspapers tell us that to add insult to injury, some of those Russian tankers hauling awaJt our scarce gasoline were shipped to Russia by the United States via lend-lease, and have neither been paid for nor returned. Must diplomacy always mean appea".T""lt

Lincoln uttered one of his immortal thoughts when he declared' that the great principle that has held the United States together is "that sentiment in the Declaration of Independence which gave liberty not alone to the people of this country, but hope to all the world for all future time." ft's to back up that pledge that the United States is spending billions abroad today. Neither Hitler nor Stalin had any understanding of such unselfish ambitions, choosing to believe that we, like themselves, sought conquest.

On every hand these days I hear the comment that good stories and jokes are so very scarce, and men wonder why. I think it is because of the times we are living in, and the threats that hang over the world. The First World War developed a million good stories that were heard in spite of the cannon's roar, and read in spite of war headlines. World War Two did not develop half a dozen really good stories, all told.

And this postwar period is even less funn5r. That's why good stories are so few and far between. We hear a lot of "gags" over the air, but they are not stories, and most of them are not funny. We used to think that laugh-creators were divided into two parts; wit and humor. ff it wasn't one, it was the other. But the radio "gags" of today must have founded an entirely new school of thought, for, measured by accepted old-time definitions, they are neither wit nor humor. They are just "gags." And they are not of the

The movie industry could be of wonderful help in times like these by making and showing pictures that build morale and spread sunshine and good cheer. But the movies fail miserably along that line. Most of the offerings on the screen today are stories of drunkenness, depravity, murder, violence, intrigue, and general cussedness. fnstead of joy, happy thoughts, and inspiration, they hand us an unlimited quantity of groans, curses, and tears. Technically the movie industry ranks high. In the thinking department, it ranks lower than the proverbial whale's hips.

John Ruge, writing in Collier's, hits the nail on the head. He quotes one !\roman as saying to another: "The Lord knows there's enough misery and unhappiness in the movies without having it in real life, too."

George M. Cohan, a genius of the entertainment world, used to say with regard to plays, songs, or stories, you should "always leave them laughing when you say goodbye." That's the sentiment we need today in our entertainment world. But we haven't got it. I have been looking to see Eric Johnson, movie Czar, crack the whip over the moving picture industry and advise them to cut out all the crime and gloom and make and show pictures that would follow George M. Cohan's advice. It could do a world of good in times like these. Laughter and song are the best medicine for individuals or nations. We could use a lot of both' i. * * ft is very likely that no story of the sort ever printed brought more smiles of satisfaction from both wood preservers and lumber manufacturers than one in the May issue of "The Wood Preserving News." Looks like both have smiles coming. ft appears from that account, printed with illustrations, that the Santa Fe Railroad has just built a freight house 716 feet long in its yards in Kansas City, Mo., of timber construction. But the big story is that the timber used in this building, even for the foors, is used lumber, taken from Old Santa Fe structures, some of it thirty to forty years old. Part of it was reworked smaller than its previous size, and some was re-treated. All was very aged stuff, but in the soundest and most useful condition. All of it had been treated before being used in the first place. Most of it was previously used in the construction of railroad bridges. When these obsolete structures were torn down, the materials were found to be in first class condition. The story mentions the use of both Pine and Fir in the new-old building.

AND NOW THE BARK. Only a short time ago progressive lumber manufacturers were $ront to remark that the day would come when they would find ways and means to utilize everything that came out of a log except the bark. Now some of them are using the bark, as well. Many years ago, through laboratory research, The Pacific Lumber Company, of San Francisco, began selling valuable products made out of Redwood bark. They still do. Also, many years back, over in Mississippi, progressive lumber folks began making pressed board out of bark, and other sawmill waste; still a most successful enterprise. Later, other Pacific Coast interests began making board out of bark and other wood waste. And now the Weyerhaeusers have started operations at a big plant at Longview, 'Washington, where they use Fir bark to make five valuable products. So the lumber industry, through the laboratory, makes Progress.

At Longview the Weyerhaeuser plant wastes no part of the Fir 1og. All slabs go to resaws and have all the good wood extracted from the now valuable bark. Dry sawdust goes into little pressed firewood logs. A huge remanufacturing plant cuts up what lumber doesn't make boards and planks. Two pulp plants take everything else. Short lumber is endlocked to make long lumber. Boards are side glued to make wide boards. Nothing is thrown away. And, they say, it will be more and more that way. Very low grade lumber can always make valuable pulp. Very high grade logs will be sliced for plywood. Yes, dear friends, even the bark goes now.
