8 ILLINOIS ENGINEERING EXPERIMENT STATION federal government as well as with many industrial interests of the state is already assured. On the following pages are mentioned some of the most important appliances which are available for use in various lines of research. Only a few words of description are possible with reference to each. In connection with this article are given several reproductions showing the laboratories in which the investigations are in progress, and also the most important apparatus. I N THE MECHANICAL LABORATORY • 1. A 210 H. P . Heine water-tube boiler especially arranged for testing Illinois coals. This boiler is a duplicate of the boilers being used at St. Louis by the United States government in testing coals from various p a r t s of the country. A Green chain grate stoker is installed under this boiler, and draft is furnished by a Sturtevant induced draft fan, drawing the gases t h r o u g h an economizer. The chain grate under the boiler may easily be removed and a plain furnace for hand-firing substituted. A complete equipment of auxiliary apparatus necessary for boiler tests is available, including recording and optical pyrometers, and standard and recording apparatus for continuous gas analysis. Facilities are now available in the department of Physics for calibrating all thermometers and pyrometers used in work of this character. 2. An independently-fired Foster superheater capable of superheating the steam from a 150 H. P . boiler 300° above its temperature at 120 pounds gauge. 3. Several residence heating boilers, for both steam and hot water. These boilers will serve to compare the values of such various coals as are offered in the Illinois market for domestic purposes. 4. A 10-ton York refrigerating plant for the production of cold or for specific tests. With this plant there are 17 cans for ice making, each holding 100 pounds. T h e possibility of subjecting various building stones or other material to alternate freezing and warming is worthy of consideration. T h e effect of fifty winters might thus be known in a single month. 5. A liquid-air plant with a capacity of about t h r e e quarts an hour. I t consists of a Norwalk four-stage compressor, compressing up to 3000 pounds, together w i t h a H a m p s o n liquefier with facilities for temperature determinations.
