Sly pioneered in the development of positive dust collection and were the original patentees of cloth type filter The most effective—as well as simplest and cheapest—method of collection is by cloth filtration. The Sly Filter uses more cloth than any other and hence has greater filtering capacity.

This additional capacity plus savings in operation and maintenance make the Sly Filter most ine*pensive in the long run. Ask for Bulletin 98 and state your condition so •& thatwe can write you fully. SEND FOR T H I S BULLETIN

Once a&ain selective service legislation is before Congress. It is discouraging to note how quickly the difficulties experienced during World War II in obtaining satisfactory and workable deferment procedures for those essential to the war effort have been forgotten. Norman Shepard, chemical director of the American Cyanamid Co., speaking in behalf of the Manufacturing Chemists' Association before thy House Committee on Armed Services, recalled the experiences of World War IT: I had the thankless job for my company of seeing that our technical people were properly utilized in the war effort. . . . I was, in the last analysis, the arbiter whose responsibility it was to carry the argument to Selective Service Headquarters when the lower appeal board had turned down the case. At all levels in selective service, decisions as to deferment of technical personnel were made, by and large, b y military or nontechnical personnel who, regardless of their unquestionable integrity and conscientiousness, could not possibly evaluate the essentiality of technical people. . . . Our chemical companies, which arc so dependent on engineers, chemists, physicists, etc., found it necessary to utilize a staff in large numbers and at all levels, from secretarial to managerial, in an attempt to obtain deferments. The correspondence was voluminous; telephone and telegraph lines were tied up . . . t o try to save, for the war effort, men who were vitally needed on the industrial front. And in spite of all this many important technical men were lost and inducted into nontechnical jobs, or jobs where their talents were only partially utilized. And in literally hundreds of cases where deferment was eventually granted the individual in question was literally dragged from the induction line . . . but many times action came t o o late! I t does seem logical that we should learn from the bitter experiences of the past war. Few seem to disagree* about the essentiality of scientists and engineers when they are employed in important war work. Yet, the old hue and cry of class legislation and blanket deferment is immediately heard when the request is made for legislation and administrative procedures framed so as to provide proper machinery t o deal with occupational deferments. The Selective Service Act under which we operated during World War II was considered at the time of its enactment nothing more than temporary. W e are approaching the problem once more on the same illogical basis. The proposed drafts have been written for an "emergency." Tf we

find .ourselves in a real emergency, the chances are millions of men will be drafted under a law which is perhape satisfactory now, but which will greatly impede our efforts should war come suddenly. Practically every scientific society has called the attention of our legislators to this grave danger.
Con#i*$cni Incorrect answers on examination papers may occasionally reach such •heights of absurdity as to afford a wry humor t o the otherwise discouraging task of learning what students failed to absorb. But what we think amounts t o a record for sustained absurdity has been called t o our attention by Bernard Bettman, assistant professor of chemistry at the College of Idaho, Caldwell. Prof. Bettman affirms that all of the "original" answers t o follow were given by the same student during an examination in first year inorganic chemistry. The student's answers to a question on definitions were as follows: Adsorption—is the taking up process. Indicator—shows what is expected to happen. Reversible Reaction—when chemical keeps changing back and forth. Hydrate—takes on water. End Point—when the reaction stops. Charles1 Law—the temperature of a gas is inversely proportional to the pressure upon it. Dalton's Law—the volume of a gas is directly proportional t o the temperature on it. Transition Temperature—temperatu re a t which it changes over. Answering whether or not a certain reaction was an example of oxidation and reduction, he replied, "No, just oxidation because it takes on or adds to." Asked to write the equation for the decomposition of chlorine water by light, he wrote: Cl. H*0
decompose8
> Cl s + H 2 0
Answering why hydrogen chloride cannot be collected over water like oxygen or hydrogen, he replied, "Chlorine water will be formed." Writing an equation illustrating the combination of antimony and chlorine, he wrote: An

Yes, you guessed it. Prof. Bettman gave the student a straight zero.
