Freshmen Engineers

EXTEND to you a welcome from your. chosen Alma Mater. You are strong in numbers. We believe you to be strong in the qualities essential to the raw material out of which, with tireless effort, can be made good engineers.

The making of an engineer is an extended and strenuous process, which will continue long after your graduation from College. You must be tested and perfected in many a fiery furnace of experience before attaining the complete, all around engineering strength essential to the real engineer.

But just now you have before you four glorious years for the college part of your training. College work and college influences have unique values, not otherwise attainable. Use your college advantages to the utmost. Make many college friendships; but with discrimination, for they will endure. Seek for college culture; it can make your whole lives brighter and nobler. Establish high ideals firm in your souls; the ideals of an engineer must be as sound and immovable as the rocks on which his structures rest. Take care of your health; a feeble body is like a rickety engine.

The motto of the College you have chosen is "Science with Practice." The characteristic of her engineers is ability and willingness to work. Willingness to work is largely habit. Whatever else happens, do your college work well.

Remember that in the faculty you have well wishers. Let us be your friends and counselors. Success in college and in life to the class of 1918.

The furnishing of heat to a group of buildings as widely scattered as are those on the Iowa State College campus is an interesting problem calling for the exercise of rare foresight and judgment.

The heating engineer would rarely be called upon to develop plans for so extensive a system at any one time. The system grows with the institution. The extent and direction of growth is entirely problematical; and especially so if no comprehensive plan has been adopted for the location of future buildings. This article will trace the growth of the system of distributing heat to the various college buildings. The heating system located in the buildings will not be considered; attention being given only to the heating plant and location, construction and equipment of tunnels.

The "Old Main" a four story brick building located on the site of the Central Building was the first college build ing to be heated by steam. This building had a basement boiler room on the west side of the building in which were

*Prof. of Mechanical Engineering low a State College

located four small horizontal return tubular boilers which furnished steam for a low pressure, direct gravity system of heating. All other early college buildings were heated by soft coal stoves or hot air furnaces.

Morrill Hall, which was completed in 1891 was heated from a small boiler located in a wooden shed placed about 60 feet west of the building. The steam and return pipes were run above ground, the insulating covering being protected from the weather by a wooden box. In 1892 a one story building 35x70 was built on the site of the present Steam and Gas Laboratary. In this building, called the Power House, were placed the boiler, engines and electrical generators that had been furnishing current for the electric lights used by the college. At this time the city of Ames

did not have street lights of any kind and its best citizens did not hesitate to carry coal-oil lanterns on dark nights. Old Enginnering Hall, now the Engineering Experiment Station was heated in spots by soft coal stoves. In 1893 Prof G. W. Bissell installed in this building a system of steam heating. The supply main was carried overhead in to the power house and connected to the exhaust steam line from the engines. This was the first attempt on the college grounds to utilize the heat in the exhaust steam from the engines. This system showed such economy and was such an improvement over stoves that the college authorities directed Prof. Bissell to extend the system to the Old Chemistry Building. It was discovered that there was a brick tunnel 3 feet wide and 4 feet high leading from the basement of Old Engineering Hall into the basement of the Chmistry Building. This tunnel had been constructed in the late seventies in connection with a hot blast heating and ventilating system for the Chemistry Building. This tunnel had been abandoned for years. It was opened up and utilized for carrying the steam and return mains into the Chemistry Building. This was the first attempt to carry steam mains underground on the college campus. It is a matter of interest that the west end of this tunnel is still in service carrying steam, compressed air, electric and telephone wires into the Engineering Experiment Station.
