A green sorter shed, 613 feet long, adjoins the sawmill. and provision made for as many more as may be required from time to time.

The stacks move through the kilns into a cooling shed where after being held as long as is necessary they are transferred to the unstackers. The unstackers are of the automatic type developed by Chief Engineer A. H. Onstad and are similar to those installed at the Longview plant.

From the unstackers the lumber is delivered on rolls to rlrv sorter chains (505 ft. long). These are served by a bridge type electric crane which deliverF the units of lumber into what is known as the unit transfer chain. This transfer chain takes the lumber to the rough dry sheds of which there are two. These are huge structures and the largls_t of their type ever built, each being 1,205 feet long and 78 feet wide. They adjoin, and have a combined capa-city of twenty-five million feet. Here the lumber is handled by an electric crane, and is moved from storage by the

It is served by an overhead electric crane which puts the lumber either on rollers leading to the stackers or on cars going to the yard. Division of lumber for the kilns is made unit transfer chain which takes it to the planer orto the loading docks. in this shed and after going through the stackers the lumber is held in a kiln-storage house, lA6x377 ft., until placed in the kilns. Thirty kilns have already been built

As from 15 to 20 per cent of the cut of the mill is expected to go into boxes, it is obvious that a modern box factory, not yet completed is one of the important units in the operation. Also the high quality of timber available, especially adapts it for shop lumber uses, and a large percentage of the mill's volume will be manufactured for that purpose.

An almost bewildering maze of "sorter" and "storage'' shed.s characterizes the rnodern sazumi,il of eration. After lumber in log-form enters the Klamath Falls mill, it does not again "see the light of d.ayj' so to speak, until it is unloaded from the railroad car by the lumber dealer.

Power for the operation of this new plant and steam for the kilns is provided by a modern power house equipped with four 800 h.p. ErieCity boilers and a 5000 kilowatt turbine. The stack serving this plant is 280 ft. high.

Lumbermen will be interested in thefactthat ninety per cent of the lumber required for the railroad and other construction work was cut by a small portable sawmill on the property. Later a small planing mill was built which has run continuously cutting more than sixteen million feet of lumber for the mill buildings.
