Recently the Daniel Guggenheim Fund provided funds for the Airship Institute, which is located at Akron, Ohio. This laboratory con- tains a six foot Wind tunnel and other experi- mental facilities for lighter-than-air research, so that the Institute will carry on theoretical and experimental work in the lighter-than-air field both at Pasadena and Akron. Both laboratories are under the direction of Dr. T. von Karman, who is in charge of the experimental and theo- retical researches. Experimental and theoretical researches are conducted on the basic problems of How in real fluids, with regard to the scientific foundations of technical hydro and aerodynamics. The basic problems of applied mechanics, which relate to the properties of materials and the theory of elasticity, and practical problems in aerody- namics and structures, are also included in the research conducted by the department. ,IU -4. ,ff ff-,L V Q sf' 0 ff?

DEPARTMENTS PROFESSOR ROBERT L. DAUCHERTY The Department of Mechanical Engineering The Mechanical Engineering department, un- der the supervision of Professor Robert L. Daugherty, has as its aim to give work, both in theory and practice. It is the practice of the department to arrange for tests to be made out- side of school in industrial plants, and other places, in order to give practical knowledge to those taking the work. There is extensive research being carried on in a number of lines this year. The following investigations are being conducted: experimen- tal investigation of induced turbulence in annu- lar tubesg investigation of the characteristics of a centrifugal pump under abnormal conditionsg development of an optical type of diiferential pressure gaugeg investigation of new methods for determining instantaneous velocities in liquids moving at relatively high speedsg a study of relative properties of commercial au- tomotive lubricating oilsg diffusion of manga- nese in irong effect of rapidity of breaking on the energy requiredg and elongation and con- traction of tensile test specimens. It is interest- ing to note the variety of the researches that are being conducted, and most of them are of prac- tical importance. Twenty

DEPARTMENTS I DR. JOHN P. BUWALDA The Department of Ge Within convenient reach of Pasadena occurs an almost unrivaled variety of rock types, geo- logic structures, and physiographic forms. Stratigraphic and faunal studies may be pur- sued in the Cenozoic and Mesozoic sedimentary rocks of the Southern Coast Ranges, and in the Mojave Desert Region. There remain many regions to be explored and, also, there are many problems inviting critical investigation. To those interested in economic geology the oil fields, Portland cement plants, and the various metal- liierous and gem producing regions of Califor- ol ogy and Paleontology nia, Arizona, and Nevada offer excellent oppor- tunities for visit and research. A fully equipped Seismological Research Laboratory, situated on the west side of the Arroyo Seco, is devoted to researches in seismo- logy and to the development of the instruments used in a seismological laboratory. Collections from many invertebrate and ver- tebrate faunal horizons in the sedimentary record of western North America permit the student interested in paleontology to secure an intimate knowledge of the history of life. 2.0, . , 655, 4g:w ,y,,,,,,-1 f' ,C -M ' f f f' W 'VW' ,wa , -' , 'p ff C I f firf .- f x 1 f f' ' - ,f if W' ' x W V f f f 1 ' ' 1 ffjef X.
