Some aspects of silicosis in industry. G. Quin Lennank. Jour. Slate Med.. 37, 602-606 (1929); V. S. Pub. Health Eng. Abs.. 10,1HS, 1 (1930).--Inhalation of silica dust causes the formation of fibrous tissue in the lung substance, gradually extending and encroaching on the aerating function of the lung tissue. Crystalline sandstone, quartz, quartzite, and flint produces a crystalline dust which is much more harmful than dust containing amorphous silica. The onset of the disease is very gradual and at first difficult to recognize. The common complication is pulmonary tuberculosis, which is usually rapidly fatal. The use of water, steam, oil, and mechanical equipment for minimizing dust in factories, quarries, and mines is discussed. (Cut.) Asbestosis and silicosis. M. J. Stewart. Chem. and Ini., 49, 34 (1930).--Sili cosis was formerly believed to be the result of mechanical irritation by fine particles of silica; it has now been traced to the action of colloidal silica. S. believes that both silicosis and asbestosis are due to chemical effects. H.H.S. Use of aluminum vs. ceramics. Anon. Ceram. Ini., 14 (4), 423 (1930).--Alumi num shingles, roofing, and corrugated sheets which are standard products of growing importance have been joined in this field by ornamental castings for crestings, span drels, cornices, finials, and other metal accessories. Several recently constructed office buildings carry from SO to 100 T. of aluminum mainly in the form of cast spandrels or ornamental exterior wall plates and sills. F.P.H. Effect of abnormal sir conditions on mine workers. R. R. Savers. Bur. Mines. Information Cite., No. 6245, 22 pp. (1930).--The report gives a summary of recent investigations on silicosis in Australia. England, France. Germany, Russia. South Africa, and the U.S. Also a summary of recent investigations on abnormal air con ditions (abnormal temperatures and humidities) in England. France. South Africa, and the U.S., and some toxic gases found in mines. RA.H. Mechanical and human elements in smoke abatement. George C. Fisher. Trant. Amer. Soc, Mech. ng,, S2 [1|, 59-63 (1930).--A brief history is given of smoke abatement in Nashville, with the local conditions, technical details, and general policies followed. The human elements that entered into the problem of enforcement and the educational effort to put smoke abatement into effect are discussed. E.P.R. Rate of chemistry in ceramic industry. L. P.

Kilt was presented before the Chicago meeting of the Amer. Soc. of Mech. Eng. Kift states that the wage incentive must be large enough to bring forth the desired results from the employees. Most incentive plans need a penalty clause to correct conditions not reached by regular methods. The payroll investment should give greater returns by the wage incentive method. - E.C.C. Cost of modem glass factory. W. F. Schafhorst.

SECRETARY'S LETTERS Membership in this Society We are sending you a sample copy of the Journal. This Journal reflects the activities of the members of the Society, but does not constitute the entire activity. The principal activities of the Society are in the committees and in the Divisions, through which means ceramic education and research are promoted and activated. ACTIVITIES OF THE SOCIETY- 335 The Journal is only one of the tools used by the members for carrying on the work in which they are engaged. It does not, however, reflect the results obtained. You will find each monthly issue in three parts. This makes really three books under one cover, the Journal, containing reports of original researches, the Abstracts, and the Bulletin. Each of these has its own pagination, and in the December number each has its own index, so that the members may tear them apart and bind them into three books, each self-contained. We have had many persons tell us that the Abstracts alone are worth far more than the membership subscription price. They cover the world's literature of interest to ceramists so far as is revealed to us from readings of abstracts obtained in magazines, transactions, and other places, from all countries abroad, and from all sources at home. Memberships in the Society are of two sorts, personal and corporation. The corporation dues have not been changed. The pemonal memberships will be advanced to $12.50. Anyoae joining the Society now will be received as of 1931 on payment of $12,50 dues for personal, and $25.00 for corporation and will receive the current numbers of the Journal. . We certainly hope that you will be interested. Ross C. Purdy, General Secretary Mr. Ross C. Purdy, Secy., American Ceramic Society, 2525 N. High St., Columbus, Ohio Richards Brick Company Edwardsville, 111,, Nov. 7, 1930 Dear Sir: I was very pleased to see your article, "National Structural Clayware Manufac turers' Association" in the October issue of the Journal. I heartily agree with you that there are many advantages in "having but one association to include all the structural day product manufacturers. I note that you would indude terra cotta in this group. My personal views are that the interests of terra cotta are somewhat different from the interests of face brick, com mon brick, structural tile, paving brick, etc. The manufacturing of terra cotta is a highly specialized branch of the day products industry and while from a sales standpoint, it might be considered as a competitor of the other products mentioned, nevertheless from a manufacturing standpoint it is not so strong a competitor. It would not be very easy for the average terra, cotta plant to go into the production of face brick, while we all know it is a very simple matter for the average common brick plant to go into the pro duction of building tile, face brick, or other products. It seems to me that there are other reasons besides those brought out in your editorial that should urge all manufacturers of clay products to join in one association. It is commonly known that both face and common brick are being produced today in plants originally designed for the manufacture of paving brick and that as a result, both the face brick and common brick market are overproduced and demoralized as to price. If the combined efforts of all brick manufacturers were put back of a campaign to in crease the use of paving brick, it seems to me this would be the greatest possible help not only to the paving brick plants but also to the face and common brick plants.
