The most interesting thing was the control of the (lollies in the coal mine. A very clever arrange ment of safety devices makes col- lisions of the cars impossible. All the guide does is push a button in his car. Every thing else is con- trolled by automatic devices. Another interesting feature be- hind the scenes is the arrangement of the switchboard on the stage of the museum auditorium. A dupli- cate set of control-boards assures easy manipulation, and the rheo~ stats may be operated by timing devices. The other control board is adjusted for a later part of the show. All electricals are required to take “industrial studies” in their senior year. It is one of the elec- trical’s most interesting classes, giving them a view of the practical aspects of this branch of electrical engineering. U. OF C. ANATUMY LAB VlSlTED El“! BEOLOGY GROUPl insist Tuesday, Mr. Edwin Cics‘ lak‘s class; in microscopic teclmi» one went on a field trip to the limit“ iomy department of the Univer» sity oi” Chicago. Here the close witnessed a demonstration of the filtmonh-Gersh Freezing Drying; Method. given by Dr, Sylvia. lien- slcy who is coauthor of "A l-‘luml‘ bout; of lilistologloal and Cytology?» col Technique.” The» Altmnnrv Gersh method is a technique for drying; frozen tissues in a vacuum at El low temperature for the study of coils and tissues. The purpose of the £1"chng drying technique is to enable investigators to oh tam oectlomr. of tissue structurally and chemically unchanged. in this method, the tissues are frozen instantaneously in isopcir lane at a temperature of 430°C. They are then transferred to a. drying chamber at 30°C. and de- hydrated in a vacuum. li‘ree hand sections mode of the tissues are cleaned in glycerin and studied directly under the microscope. Materials prepared in this»; man- ner may he used for solubility studies of the various components: of the cells. The validity of cellu- lar structures can he approached by this method as no chemical or structural changes are induced. Br. lienslcy said that by this method of immediately freezing the tissues, they were able in one instance to freeze heart sections. Photo-micrographs of materials prepared in this manner are cu- iarged 255,000 times and bring out vividly the structures in liver cells and neurones, .lANlTORESS FOR 35 YEARS, QUITS ARMOUR SERVICE Last week saw the seventioth birthday of a lady who can claim to he one of Armour’s oldest cm» ployccs.

Moor Discussion ill Pertinent Problems in llity Services 'l‘hirtyeight hundred miles of iron water pipe and more than eighty million dollars worth of utilities, compose only a part of the extensive underground not work that lies beneath the city of Chicago. Waylon Talks to A.€i.fl.llll. These facts were explained to the A.S.C.l?3. on Friday, March 8, by the speaker, Mr. Loren. Clayton who is assistant civil engineer to the city of Chicago. Mr. Gaytou showed with slides the develop» ment of the underground system. Now 'lli‘iltration Plant. The Sanitary District of Chica- go operates a vast; system of sour» erage. A one hundred and sixty-- eight mile tunnel helps to take care of the sewage disposal problem. A filtration plant which will be the largest in the world is lacing constructed at 79th Street and the lathe. ‘lli‘roiulut 'l‘mmolo Still Wood The freight. tunnels play an im’ nortant part in the maintenance of large buildings in the loop. These tunnels are used to haul incoming and outgoing freight, coal, rubbish, etc. The trucking in- dustry, however, has taken over part of this business, but the freight, tunnels still render an lm-v portam Hervice. The utilities maintain a vast network of underground lines. These lines are usually located seven feet: beneath the surface of the ground. During the building of the subway, the utility lines, freight tunnels, water, sewerage and gas blocs have presented a. major problem. This network had to be relocated before the may subway tube could be projected. New Subway a, Problem Three different problems in the digging of the tunnel have had to be met, The first, digging through hard clay, was accom- plished by tunneling, and then supporting the clay roof with heavy timbers. Digging through colt clay was done by use of a large steel shield which was push— ed forward. A third problem, ex~ tending the subway under the Chicago river, was accomplished in an interesting manner. A de— sircd portion of the river floor was excavated, and a twin steel tube two hundred feet long was sunk into place. The tube was built in a: dry dock at South Chi- cago and then floated to its final reeting place under the Chicago river at State street. The old State street bridge had to be re moved for the operation and will be replaced by a new and larger one. iriouorory Ealftflfifi~ (continued from page one) people who are willing to work and think.
