take cave of his by-products and bis factory waste, he must be given some 

 standard in the matter, and know what is permissible and what is not per- 

 missible. It seems to me that here again we have the argument that this 

 work should be done by the Federal Government, assisted by the States. 



Mb. Leach : I think that Mr. Barber has been misunderstood here, 

 also that he has not fully understood what was said or what action was 

 taken at the conference called by the Secretary of Commerce in Washington 

 last June. The Secretary said that, as a servant of the people, he was there 

 to aid the States in solving the problem in regard to trade waste, and that 

 he was ready to receive any advice from the delegates as to how he could 

 aid them. I think the Secretary will give the States the same square deal 

 that Mr. Barber expects to give his manufacturers, and, in the end, every- 

 thing will work out satisfactorily and Mr. Barber and the rest of the State 

 Commissioners will be in favor of any sound and sensible trade waste law 

 that may be enacted. 



Mr. Babbee: Has there been any effort to find out what industrial 

 wastes are worth? The paper mills of our State were ordered to put in a 

 screening process to take out the solid waste matter that they were deposit- 

 ing in the rivers. We recommended a machine known as the "Save-All," or 

 some other process that would take out the pulp used in the manufacture 

 of paper. Practically all the mills did something. The next year the super- 

 intendent of the largest plant in Wisconsin said he wished we had made 

 him put in those machines ten years before, as he had made enough that 

 year in the saving of the waste products to pay for all of the machines. 

 A paper mill at Kaukauua has put in a machine for reclaiming the acids 

 used in the manufacture of the paper, and they are using those acids over 

 and over again. The rest of the mills do not put them in because they are 

 not forced to do so. 



Mr. Buller: The same condition exists in most of the paper mills 

 in Pennsylvania. They are reclaiming valuable by-products since the agita- 

 tion for cleaning up the streams has developed. There was a plant on 

 Tulpehocken Creek, manufacturing manganese iron from Cuba. The wash 

 from these ores was very poisonous, destroying all fish in the streams. The 

 matter was taken up with them by the Department of Fisheries and they 

 installed an electric precipitator eliminating the water entirely. It cost 

 the company $30,000, but they are reclaiming a valuable by-product in the 

 form of potash which is more than paying the expense of installation.
