This report comprises the minutes, papers read and discussions had at the fifth, sixth and seventh meetings of the commission in 1909 and 1910, covering various phases of the water-supply and the sewage disposal questions as related to Chicago and other cities along the Great Lakes, together with a number of papers on sewage disposal in Indiana, disposal of starch-factory wastes and a number of plates and tables relating to all these subjects. Dr. George B. Young, the president of the commission, discusses the dissemination of typhoid fever by lake vessels and recommends the protective vaccination against typhoid of all employees in the lake navigation service.
These papers are valuable as studies of the important question of the water-supply of the large and growing cities surrounding the lakes. The commission, as announced some time ago, may be discontinued or merged with the Great Lakes Basin International Pure Water Association, formed
