Under such "general care" some of their workmen-- those exposed to silica, and siliceous, dusts--have been the atmosphere should constantly be alert and watchful, discounting to the fullest extent every possibility of danger. Employers should not conclude that chev have entirely eliminated danger of silicosis, or of anv type of pncuiuonoconiosis, sim ply because the air is seemingly free from dust. It should be borne in mind that the particles w hich do the most harm are invisible and th at When management and workmen pool their In terests in behalf o f safety, then certainly safety w ill finally be w on . ! Research lies w ith th e scientist, but the intelligent application of the knowledge thus obtained, as it applies to occupational dis eases, is a moral responsibility o f industry. : M g c iu n i just referred to. However, froth now on, w ith the spread of common, or at least available, knowledge of the peculiar danger of certain dusts, only special care w ill safeguard the interests of employer and workman alike. ^CAUTIONS NiiccssARY w iu k b anourous or IOKONOU.
