Perrolt's Army Work. il. St. J. I'errott, who Is a product of I tho rnieri'iy (.f North Dakota, entered! the government service in July, 101", as a civil tan in the employ of the Uftltea States bureau of mines at rittsbnrg for I the purpose of developing a gas mask for tin: army. At Pittsburg experiments were made on the proper kind of absorbent to put In the gas ma;k In order to protect our soldiers overseas from the clilorf ne, mustard and other deadly gases which the Germans used in warfare. Experiments were made with gas masks u inter actual war conditions, those en - ' gaged In the experiments being exposed to the gases in the same way as the sol- d!er in action. j Perrott was shortly afterwards trans- 1 terred to the government experimental station at Washington, where he was placed In charpe of a group of twelve research re-search chemists. This unit developed means of protecting the soldiers ugainst t he poison gaa In a very effective way. . fabric was developed for protecting the hands and body of the soldier from the offectH of inualard gas. Miustard Gas Deadly. In the course of developing the fahric for the mask all men In the laboratory under I'errott made actual tests on themselves them-selves as to the efficiency of the fabric in piptection against mustard gas. , chemical chem-ical method for detecting the presence of mustard gas in he field was also developed devel-oped .here. This was necessary, due to the fact that imistani gas cannot be detected de-tected by the senses, and the soldiers were often badlv burned intcrnnlly by breathing the gas for long periods without with-out knowing they were in it. Perrott subsequently was assigned to the work of developing a mask for protection pro-tection against poisonous smokes, and supervised the large scale production of a protective fabric fur keeping dugouts free from smoke and gas. lie was to have gone to France in the middle of November. Novem-ber. 1818( to supervise the construction of dugouts there, but the a rn list ice was signed Just before the time for his dc-1 pa rture. Reducing Carbon-Black Waste. At the close of the war Perrott went Into the service of the bureau of mines in Pittsburg to work on the problem of reducing the waste in the manufacture of carbon-black from natural gas. Carbon-black Carbon-black Is a soot formed when natural gas burns with a smoke flame against a cole1, surface. Over forty billion feet or natural gas are used annually in the manufacture manufac-ture or this product, and a very small yield is obtained. As a conservative measure, it was thought necessary to luxes lu-xes tigate more efficient methods of producing pro-ducing tbp material. Perrott studied the methods of manufacture, doing considerable consid-erable field work in the southern states, besides studying the properties and gases of the product, subsequent to which he wrote a bulletin for the bureau of mines giving the results of-his investigation and suggested ways of increasing the efficiency effi-ciency of the present process. To Be Probed From Air. Monnott has assigned Perrott to the perusal of data on atmospheric conditions of late years, and In his airplane flights ho will make tests considered of the greatest importance in arriving at a solution so-lution to the problem here. It was expected that the flights would begin at once, but, owing to the absence from the city of the airplane of the Western Aircraft corporation, a rra nge-nients nge-nients for engaging the airplane have been deferred until its return, which Is expected shortly. At the next monthly meeting of the Federated Association of Women's clubs, to be held Monday afternoon at 2:l?0 o'clock in Civic Center, Mr. Monnett will address the cbib on the smoke abatement problem. The women have exercised strong Influence In this movement in the past, ripd are intensely Interested In smoke abatement from ail angles. It is the purpose of the meeting to formulate methods by which tho aM0u3 local women's ciubs can assist In 1 he movement move-ment through gathering of data In the fields or in other lines. It is probable that they will center their efforts on the domestic problem, as this is the largest problem in the point of numbers, "and their hlp will be very much needed. As educational propaganda is released from time to time dependence will .be placed upon the f women for Its circulation circula-tion and of putting Into effect the recommendations recom-mendations relating to the operation of household equipment. Mr. Monnett will leave the city for a time Monday afternoon, after-noon, and on bis return expects to find considerable progress made in the campaign. |
