the attendants and employes. On Point Airy, by the use of the buildings that were on the different plots bought by the State to make up the hospital farm, such a settlement can be easily made up. Its inhabitants would pay rent to the State. They would be particularly fit and proper persons to board and care for patients whose condition was suitable for that sort of a life, and the patients could have many privileges and benefits not possible in the hospital. Point Airy's little Gheel on such a plan would be a most interesting and valuable extension of the beneficent rule of St. Dymphna. The St. Lawrence State Hospital was built and is operated under the supervision of a board of managers, whose fidelity to it is described as phenomenal by the people of Ogdensburg. The members of the executive committee, Chairman William L. Proctor, Secretary A.E. Smith, John Hannan and George Hall, especially Mr. Proctor and Mr. Smith, have given as much time and attention to it as most men would to a matter in which they had a business interest. The result has been a performance of contract obligations in which the State got its money's worth. The people of Ogdensburg, too, have taken a great interest in the institution. Such men as Mayor Edgar A. Newell, ex-Collector of the Port of New York Daniel Magone, Postmaster A.A. Smith, Assemblyman George R. Malby, and his predecessor, Gen. N.M. Curtis, who was the legislative father of the hospital scheme; Frank Tallman and Amasa Thornton take as much pride in the institution that the State has set down at the gates of their city as they do in their cherished and admired city hall, which combines a tidy little opera house with the quarters necessary for all public and department uses. The executive staff of the hospital consists of Dr. P.M. Wise, medical superintendent; Dr. J. Montgomery Mosher, assistant: Dr. J.A. Barnette and Steward W.C. Hall.--_N.Y.

The term sewage many years ago was rightly applied to the excremental refuse of towns, but it is a most difficult matter to define the liquid that teems into our rivers under the name of sewage to-day; in most towns "chemical refuse" is the best name for the complex fluid running from the sewers.
