    are made. The lead metal pot is small and unliooded. There are no special washing facilities, no meals eaten in the place. No cases of plumbism were found. Enamelled Ware: One large plant manufacturing enamelled household ware was visited. Analyses of the ingredients used for enamelling failed to show any lead present. Dyeing: Two large woolen mills and one large carpet plant were visited, and analyses of the dyes used and samples of fabric made failed to show any lead present. Two large silk mills and one silk thrower were visited. In the preparing of silk, termed throwing, nothing is used but soap and water, with oil for finishing. In dyeing and weaving of silk tin instead of lead is used for weighting or giving body to the silk, and no lead dyes are used. Samples of silk were analyzed and no lead found. Shoes: A number of large shoe factories were visited, but it was claimed that no lead preparations were used in dyeing or finish- ing. Samples of different preparation were secured and analyzed. In two of the plants visited tan shoes were made, and before leaving the factory were examined and slight defects of finish were touched up with a tan dressing. But one or two men were employed at this work. The analyses of these tan dressings showed that they contained small quantities of lead, probably as a chrome. The average number of bottles used is about twelve a year, or twenty-four ounces of mixture. The workers handling the fluid were not very clean, but no cases of plumbism were found. It is evident that in this industry the only danger from lead is in the retouching of the tan shoes, and is limited to a very few workers. Coated Paper: Two large plants were visited where coated paper was made. It wa9 claimed no lead was used, and analyses of the ingredients used failed to show any lead present. None was found in the air.
