Discussion at Pacific Coast convention

C. E. Skinner: It is rather curious that this process, developed primarily to abate a nuisance should become so valuable economically. I have been familiar with some attempts in the Pittsburgh district to abate the smoke nuisance by the Mellen Institute of Industrial Research. They made a smoke survey of Pittsburgh, and a study of this survey shows how desirable it is to abate this nuisance in the Pittsburgh district. However, the values recovered are not such as to justify the cost from the commercial standpoint, and consequently very little has been done.
