ances, all apparatus necessary for the technical examination of 

 wood preservatives, standardized thermometers, cameras and 

 other apparatus required for photomicrography, dark room, and 

 all incidental apparatus required for the detailed study of wood 

 tissues. 



2. WOOD PRESEKVATION LABORATORY. This consists of both an 

 open tank and a pressure plant. The former is of commercial 

 size for treating ties. It is composed of two treating tanks and 

 two storage tanks, one of steel for creosote, the other a wooden 

 tank for salt solutions and other preservatives. The pressure 

 plant consists of a twelve-foot retort, air compressor and vacuum 

 pumps and a duplex pressure pump, and is so constructed that 

 it may be used for any of the different pressure processes. 



3. WOOD DISTILLATION PLANT. This plant consists of a retort 

 of one-half cord capacity per charge, gas tank, and refining ap- 

 paratus. The retort has been installed by the U. S. Forest Ser- 

 vice for cooperative work with the University. 



4. THE DRY KILN. This is a plant of about one carload 

 capacity and is thoroughly equipped with all apparatus necessary 

 for scientific experimentation in kiln drying. 



COMMERCIAL PLANTS. Plants for the manufacture of paper, 

 wood pipe, cooperage, excelsior, wood conduit veneers, furniture, 

 boxes, and numerous other secondary wood products are located 

 in or very near Seattle and are available for study. Pour large 

 creosoting plants and several smaller preservation plants are 

 also available. As such of these industries as are not in Seattle 

 are conveniently situated on Puget Sound, transportation costs 

 to them are very low. 



DEMONSTRATION FOREST AND EXPERIMENT STATION. Arrange- 

 ments are now completed whereby the University will acquire 

 title to a 60,000 acre tract of forest land to be used by the College 

 of Forestry as a demonstration forest and forest experiment sta- 

 tion. This tract, which consists of the Pilchuck-Sultan water- 

 sheds of the Snoqualmie forest, is very conveniently reached 

 from Seattle and offers almost ideal conditions for a school forest. 

 It has a total stand of timber of over a billion and a half feet, 

 representing nearly all species of the Pacific Northwest, but more 

 than three-fourths is composed of Douglas fir, cedar and hemlock,
