Warm Up Boilers operate most efficiently at a constant tempera- ture so a smaller boiler, capable of faster firing and cooling, was installed in 1957 to handle the swing', loads. This, Korbis said, is a temporary increased de- mand for steam, and normally occurs about 7:30 each morning. The small unit is able to pick up about 50 per cent of the increased load and then slacks off. The operation of the boilers is largely automatic, controlled by a master board that operates according to the steam generated. When natural gas is being used for fuel, this board is coordinated with the gas regula- tors. A man is always present to insure the proper operation of the plant. The plant is located between the Spud Bowl and South Fifth. It can easily be identified by the tall, smokestack with the orange and black checkered de- sign at its crown. Gas regulators on the steam boilers must be adjusted periodically. Boilers in the heating plant can operate on natural gas, pulverized coal or oil. The heating plant is readily detectable by the checkered smokestack with the letters ISU. At each home football game the steam whistle is blown when ISU scores a touchdown. X

Pipes carrying heat to campus buildings run under the side- walks, preventing ice from forming on the walks during winter. ISU's Heating Plant Operation By Wayne King Through approximately 9,000 feet of high-pressure mains and an additional 75,000 feet of low pressure lines within buildings, the ISU heating plant warms the equivalent of 1,200 homes every day. An average home is figured to be about 1,000 square feet. Physical Plant Director John Korbis said the cost of heating the college is six to seven cents a square foot per year, as compared to 12 to 20 cents for the same space and time in the average home. The total cost comes to about 575,000 a year, including the salaries of two maintenance men and four operators in the boiler rooms. Two large boilers, each over 25 feet high, 20 feet wide and 25 feet long, serve as the main source of heat for the college. Each operates at an efficient output of 100 pounds of steam pressure. The pressure is then re- duced to between 40 and 60 pounds in the mains and again to three to six pounds in the buildings, according to Lynn Tillotson, heating supervisor. These boilers are able to burn either natural gas, pulverized coal or oil. Presently gas is being used, as a result of competitive bidding by dealers of each of the fuels. The burning of pulverized coal is probably the most interesting of the three fuels. The coal is ground by air attrition, a process of forced air grinding the coal in the basement of the plant and forced into the fire box with air, where it burns in suspension. According to Tillot- son, if the fire were to go out, the coal would stack up and be ignited, causing an explosion. This wouldr1't occur with slack coal. ' 'F f .fi 'Y - :: 5 'a.,t.y-H1 f' .

They D Their Homework 3,000 Feet Above Cities By Frank York and Bob DeLange Seven ISU students do part of their homework 3,000 feet above Pocatello and find it fascinating. The seven cadets in the ROTC flight program-Dennis Felton, Don VanMatre, Bob Turner, Bill Lemons, Marsh Butner, Stan Martin and Larry Henman-were chosen from the senior Military Science students. Requirements included perfect health, 20-20 vision with a special emphasis on depth per- ception and an aptitude for finding landmarks from a map. The purpose of the flight pro- gram is to interest cadets in Army aviation and to provide experienced pilots in case of emergency. The program was reinstated at ISU this year after a two-year absence be- cause the minimum number of cadets UQ could not be attained. There is no quota on the number of pilots allowed in the program be- cause of the need for more pilots. The program as it now exists has been in operation for only five Don VanMatre calls the Pocatello tower for takeoff instructions. yearsg previously it was separate from the ROTC and was sponsored by an Air Reserve Group in Los Angeles. The cadets must complete 362 hours of flying time at an approved flying school and 35 hours of ground instruction before receiving a private pilot's license. Flight in- struction includes going through exercises to test each cadet's skills. We learn to fly with and against the windf' says Marsh Butner. They test us on how we turn the plane-around-it can't be a jerky movement. On banking the plane, it must be kept in line with the horizon. 'QA lot of people don,t realize how difficult it is to orient your- self with the ground, comments Don VanMatre. You try to cor- relate where you are to the ground and a lot of times you can't see the ground. Most of the cadets try to fly in the morning or around four in the afternoon because of the good
