It seems that the frost will often accumulate to the ex- tent of over two inches in a compara- tively short time. This is especially true near the ocean, the warm breeze carrying a large amount of moisture over the cold land, where the water condenses as frost. Snow Absurbs Sound Several interesting acoustical ef- fects are also apparent because of the porous nature of the snow. It acts like some of the sound absorbing ma- ti'i‘inls that have been put on the market in recent years, but is very much more effective. Standing only ten feet apart in a trench in the snow it was impossible to hear another per» son talking“ in normal tones. Still it is p siblc to hear a disturbance in the snow which takes place a consid- sidorablc distance away. The snow transmits sound well, but absorbs sounds that are incident upon it. Seismic Equipment Exhibited In setting off the charges of ex— plouive in taking: his seismological data Dr. Poulter found that the blast did not disturb the snow as much as would ordinarily be expected. In set— ting off one of the small charges, about one pound. the only effect was to compress the snow for about ten inches around the charge. The porous snow and the far “ll: cold served to ab- sorb all of the shock and to condense the grasses that were generated. This absorption was one of the problems which had to be overcome. It was rather difficult to get a wave front into the Show which was of sufficient intensity to give good results. Dr. Poultcr did the journalists a great favor by exhibiting a duplicate of the equipment which he used at the south pole. It consisted of the recording apparatus and a set of three of the geophoncs. He also dis~ played a set of wave tracks, taken of’ various subjects, such as street cars and steam hammers. The pictures which he showed were of the seismic party. showing the arrangement 0 the sleds and equipment. Severn] views were shown of the explosion of some of the larger charges, and of the trip which was made by air. In closing his address the speaker invited the audience to ask questions and permitted them to examine the seismog‘ruph at first, hand. crimson “l‘allcs newt l lire Edouard 1 At the regular meetingF of the Fire l Protection Engineering Society presi» l dent Paul Hoil‘man announced the date of the smoker and urged all members to attend. The date has been set as Wednesday, Feb. 15; the place, the main lounge of the union, and the time, 7:30 to 10:00 p.m. Moving pictures and Monte Carlo games have been promised with a prize for the champion gambler among the firemen, The movie “The Treasures of Wood" will show the manufacturing and finishing of rare woods; it will take 45 minutes to Show and is one of the most inter- estiner technical movies that could be obtained. Refreshments will be served, and cigarettes and cigars dis- tributed. After the smoker announcement the members were addressed by E. R. Chincholl of Marsh and Mchnnan. insurance brokers. Mr. Chincholl spoke on the fire hazards of power plants. He gave a short history of electric power generation. stating that the first real utility for electric- ity was lighting by means of Edison‘s | bamboo filament lamp. The first’ power plant was installed in Chicago in 1380 and was known as the Adams l street station. Most of the dcvel-I opment of power plants has taken place during the last sixty years. Mr, Chincholl cited many inherent hazards such as arcing, overheating, oil leakage, and explosions. Oil leakage has proved to be the most costly of these hazards. The oil, very hot from continuous use, is readily ignited when it contacts hot steam pipes. Leakage has been less- ened by welding all joints in the oil line by using flanged connections. To prevent the spread of fire in outside stations, crushed stone floors are used, while within the power house each piece of costly equipment is separated by fireproof rooms. For an extinguishing agent Mr. Chincholl recommended a spray of water for fires occurring in electrical equipment and also for small oil fires which may start in power plants.

To fill the remaining vacancies, the class decided that a standing vote be taken after the nominees left the room, Frank Pfefl‘er was elected to the office of vicc~presidcnt and Roy Jacobson was elected secretary.

Tuesday, February l4, l939 1936, the Co~op group of 7‘” '0 ‘ ‘ Engineers has; continued to grow through depression and recession. The latest addition to the. class was made January 30, 1989, and consisted of eighty students from Chicago and neighboring cities, forty in each group. The total number of (Jo-ops has now reached 303, which is only 4.1 below the number of mechanical engineers enrolled in the regular four-year course at Armour. 0f the Co—ops the largest class is in i ' second year and 1 numbers 81. The freshmen class, with eighty students, forms the second largest class. AThc third year class ranks third in size, numbering sev— enty—eight, while the smallest class is composed of the fourth-year group of sixty~four. During his four years as co-ordina- tor for the Co—op course, L. J. Lease has enrolled 379 (Do—ops. Many of these have dropped out in the past three years, but a number of the va— cancies have been filled by new stu- dents so that. the Co-op enrollment to- day is only 76 below what it might have been with no changes. With the addition of the (loops, mechanical engineers now comprise by far the largest division in the school, with 747 students. The chemical en— gineers follow with 283, which is somewhat less than either 303 (Jo—ops or 3411 regular four-year mechanicals. This year’s working schedule has been changed slightly. Instead of working in the factory in two nine- week periods and one eight-week pe- riod, with one week of vacation early in the summer and one week late in the summer, the students will work in two eight-week periods and one ten-week period, with two weeks va~ cation late in July or early in August. This arrangement will keep Clo-ops from school for 12 weeks in the sum- mer and will give instructors a one- month’s vacation. Co-op students will continue to spend twentydlour weeks of each year in school. Thecalarful r.
