The War Department also continues its administrative functions with the Civilian Conservation Corps. For the support of the War Department dur ing the fiscal year ending 30 June 1939, Con gress appropriated $719,484,989, of which sum $482,896,735 is for military activities.

The persons examined in the three plants were 423 men and 118 women, all younger than the average industrial worker. Almost half of them had previously been employed in cotton or woolen textile mills. Only 23 had been em ployed in a trade in which workers are known to be exposed to organic dust and only one of this number had pneumoconiosis. *ri a ART. See Painting and Sculptors. ASCENSION ISLAND.

The output of asbestos from United States mines in 1937 amounted to 13,896 short tons, compared with 10,924 (revised fig ures) for 1936, an increase of 27.2 per cent The quantity sold or used by producers during 1937 was 12,079 short tons valued at $344,644, an increase of 9.2 per cent in quantity and 9.7 per cent in value over 1936. The largest percentage of the total, as in recent years was short fibre ohrysotile from Vermont Arizona produces small quantities of high grade chrysotile of spinning quality and this is expected to be utilized in in creasing quantities on the Pacific Coast Pro duction in Arizona was substantially higher in 1937 than in 1936. The increase in imports of crude asbestos fibres from Africa in 1937 was noteworthy. Imports of unmanufactured asbestos amounted to 307,188 short tons, valued at $10,470,208, a gain of 26.1 per cent in quantity and 39.1 per cent in value over 1936. Exports amounted to 3,004 short tons valued at $253,734. The ap parent consumption tor 1937 (domestic fibre used plus imports, minus exports) was 316,263 tons valued at $10,561,118, a gain of 26 per cent in quantity and 40.3 per cent in value as compared to 1936. Exports increased 22.9 per cent in value. The domestic production of 1937 supplied only 3.3 per cent of the fibre needed in plants making asbestos products. While the ton nage consumption of raw asbestos materials was higher in 1937 than in any year in the previous 10, the value for 1929 was somewhat higher.

An increased demand for as phalt domestic and foreign, of 2Vz per cent in 1937 over 1936, was reported by the United States Bureau of Mines. Petroleum refineries enlarged their output by 294,302 tons, from 4,065, 622 tons in 1936 to 4,359,924 tons in 1937. Im ports of lake asphalt grahamite and petroleum asphalt apparently increased 69,785 tons. As a consequence, stocks at refineries were 193,247 tons larger than at the end of the previous year. There was an increase in domestic demand of 2 per cent from 3,962^57 short tons in 1936 to 4,049,303 tons in 1937. During the first seven -months of the year 193? there was a reported increase in demand of 15 per cent but the in crease did not hold because of a decline in road building activity. .Production of asphalt from foreign petroleum declined to the extent of 182, 452" short tons. Highway construction accounted for threefifths of domestic consumption. There was an increased use of asphalt for lighter road sur faces, especially on county and farm-to-market roads, and another increase in use for soil stab ilization. The sales of emulsions and fluxes, employed for the last named purpose rose from 55,961,368 gallons in 1936 to 62,683,186 gallons. The increase in value was $549,802 for 1937 over 1936. There was a small increase in the use of asphalt for the manufacture of roofing ma terials. Sales of waterproofing materials showed a decline. women employed, or recently employed, in three factories making asbestos textiles. The primary effect of asbestos dust appeared to be the initia tion of fine, interstitial pulmonary fibrosis which was not observed to progress as far as the nodular stage. This fibrosis was found in post mortem examinations of three former asbestos workers. Lung fibrosis, in living persons, can be detected by x-ray examination. Important symptoms of asbestosis are progressive dyspnoea, variable cough which sometimes raises blood- streaked sputum, and loss of weight The per centage of , persons in different occupational groups in the plants studied, who were affected by asbestosisvor any of its symptoms varied with the average dust concentration to which they were subjected and with the length of their em ployment^Three cases of asbestosis which were diagnosed as doubtful, were found in persons who were working where* dust concentrations ASTRONOMY, Progress of. The most im portant astronomical event during the year was the discovery of two satellites of the planet Jupi ter, bringing the total number to eleven. During the months of July and August, Dr. Seth B. Nicholson with the 100-inch reflecting telescope of Mount Wilson Observatory made a survey around Jupiter with photographic plates each of one hour exposure, thus revealing stars one mil lion times fainter than can be seen with the naked eye. In taking the photographs, the motion of Jupiter was allowed for with the result that the images of the stars were elongated while those of the satellites were circular. Altogether on the various plates about forty moving objects were found, but most of them could easily be distinguished from satellites because their mo tions were different from that of Jupiter. Thus the 6th, 7th and 3th satellites were recognized Ut*& & TVs!
