Hencoop to Palace

The "hencoop" laboratory in lvhich an apple-cheeked Bror Grondal hatched out early Pacific Northwest forest science research has mothered a mighty brood. A bare outline of the region's current projects, extending from forest research deep in the timber to market research the world around, would take pages to catalogue. Examples may be cited from Crown Zellerbach Corporation's research program at Camas, Washington-on the Columbia River near Portland, Oregon.

"Crown" has tree farms in both Oregon and Washington that total more than 500,000 acres of productive land for the perpetual harvesting and growing of tree crops for pulp and paper making. The Camas plant, largest producer of specialty papers west of the Mississippi, has grown from a pioneer pulp and paper mill of 1886, the second in the region.

This forest industry organization has 10,300 employees' A few of the products of the Washington and Oregon mills include newsprint, kraft wrapping papers' coated printing papers, facial and toilet and fruit-wrapping tissue papers, towels, napkins, bags, waxed papers, and many more things of paper. "Crown" maintains two large laboratories at Camas, one, completed in 1939, for basic production research, and a great new center for development of products.

Wood Fish Meal

One result is thriving in Eastern markets for things out of woodpulp. It was first developed to make profitable use of the residue from the spent liquors of the ammonia base sulfite cooking system at Crown's Lebanon, Oregon mill'

From the one plant the yield from ihe runoff has been about 60 tons per day. The product is a plant food which in tests has compared favorably with fish meal' The ammonia content contributes nitrogen to the soil in a form readily converted into plant nourishment. The sugars are good eating for constructive kinds of soil bacteria' The lignin fortifies the soil structure.

This new magic in wood has also shown itseli to be a versatile service product in partnership with asphalt emulsions, gypsum, oil well muds, clay slips, sprays, and various other mixtures, both organic and inorganic- It works as a binder for cores in foundry work, fuel briquettes, hardboards and road surface and as an adhesive in synthetic resin plywood glues and linoleum cement. Many more products in these and other categories employ the product to advantage.

Research Makes Payrolls

The Camas development laboratory houses a complete pulp and paper mill on an experimental scale. Toy logs, never more than five inches thick are barked, then fed by hand into a midget chipper. The continuing small-scale process is technically complete' Aty group part can be operated separately, however. The miniature paper machine turns out a sheet 26 inches wide at speeds ol 25 to 250 feet per minute. The pilot plant even has its or'vn "laboratory within a laboratory." There are all kinds of wonders to describe. It is a fascinating show, it is an educational institution, for even an afternoon visitor.

Another example of the laboratory's work is the isolation of an organic chemical of the West Coast hemlock tree called conidendrin. Separated from spent sulfite cooking liquors, conidendrin has proved to have commercial possibilities in itself.

Another Camas laboratory product that is moving fast in commercial values is a combination of a new type of phenolic resin with cellulose fibers that make a smooth' durable sheet that serves as a surfacing material for plywood, providing an easily painted facing.

It is all a far cry from Fort Vancouver of a cehtury and more ago-and the cry is "Progress !"

Studies indicate that coniferous sawdust is beneficial to microbial activity and plant growth, both when used as a mulch and when incorporated into the soil'

They still tell the story of 300 lb', 6'7" Joe Sherwood of Mason County, Washington, who in 1854, when challenged by a brash young logger to race him in felling a big Douglas fir, stood to one side while the challenger chopped away on a springboard 7' above the ground for a long start, then stood on the ground under the challenger and chopped the tree down, man and all.
