Air Picture Of Huge \(/"yerhaeuser Plant At Longview, Washington

Here is a late air photograph of the plant of the Weyerhaeuser Timber Company at Longview, Washington. Shown in the picture are the principal mill units. Not shown in picture, but important late units of the great plant are; the plywood plant, a kraft and sulphite pulp mill, a bark products plant, and two hydraulic barker units for pulp logs.

Seen in the picture are the shipping dock in the lor,ver foreground: N'Iill Number One which cuts only large Douglas Fir logs; Mill Number Tr,vo rvhicl-r is immediately to the right of the stacks and n'hich cuts only smaller Douglas Fir logs; and Mill Number Three at the far right in the picture, rvhich cuts logs of miscellaneous species ; between Mills Number One and Number Two is the big porver plant which obtains part of its boiler fuel from milling leftovers that aren't used for pu1p, plyrvood, or other wood products; and the big buildings in the middle of the picture are tl.re shipping shed, planing rnill, rough dry sheds, dry kilns, and Pres-to-Log plant.

llere are facts concerning the lumber mar.rufacturing units of this very diversified institution, each of the three sawmills being specially designed to do the particular jobs and cut the special types of timber furnished them for raw material. Each mill rvas designed for its particular part of the entire operation.

In a tremendous log pond the logs are all separated and segragated, and boomed to each of the mills ancl other units. The biggest and finest Old Growth Fir logs go to Mill Number One, which cuts strictly for grade. First the logs go through the one big band headrig, u,hich slabs them, and then slices .cants from all four sides. the cants varying in thickness. Common and structural grades oI lumber and timbers are then cut on the carriage from the remainder of the log. The cants, which are largely clear lumber, go then for more sarving to various other units of the mill. There are two double-cutting pony band headrigs, a gang, and edger, a trimmer, and a whole battery of band resatvs, re-edgers, and re-trimmers. Every device is for the purpose of getting the greatest possible amount oi clear lumber out of the log, and the fact that nearly 60 per cent of the output of tiris mill is clear, and an addi-
