An Improved Water Meter Record.
The accompanying diagram shows a meter dial record, designed by Ira Schrop, superintendent of water-works at South Bend, Ind. The idea is to facilitate the work of the meter inspector in taking an exact and rapid reading of the dial. The records are bound in convenient-sized books, which are handed in to the registrar after the reading on the dial is copied. On the reverse side is a form with blanks for name of works, city, State, month, name of meter, number of meter, statement where meter is located and by whom registration is taken. There is no doubt that a useful chart like this will supply the present need for a concise and easy method of taking the reading of meter dials, and that Mr. Schrop’s design will soon become popular among water-works people.
The manner of taking the record is by marking with a pencil on the chart the same reading as is shown on the meter dial, which is a more simple and rapid way than that now generally in vogue in watsr-works offices.

SEWERAGE PURIFICATION AT WORCESTER. Mass.—The new sewerage works at Quinsigamond were tested yesterday afternoon, says The Worcester Gazette of June 26, in the presence of a number of the members of the city government. The test was conducted by City Engineer Allen who originated the present system. The impure water from the main sewer was let on at the gate near Washburn & Moen’s Wire Mill at 4.25 P. M., and slowly flowed through the outfall sewer to the purification works. The water flowed very slowly as there is only a fall of two and one-half feet in the pipe for a distance of nearly a mile. The water flowed into the first catch basin, and from there one-half of it was carried back to the Blackstone in the same condition as when it left it, and the other half flowed through a wire screen into a second basin. From there it flowed into a run-way, where the chemical mixture was discharged into it, and then into a scries of large basins, where it settled, and the chemicals completed the work of purification. City Engineer Allen explained that the action of the chemical matter, which was mainly lime, was chiefly mechanical. The lime forms a chemical affinity with some of the impurities of the sewage and forms a sediment which settles at the bottom of the tank by its own weight. ‘Fhe matter flows from one basin to another, in all of which this process is repeated until the water becomes peifectly pure, and is then permitted to return to the Blackstone. When the sewage was first introduced into this tank it was a thick black fluid ; at the end of half an hour Mr. Allen bottled some of the water and found it clear as crystal and without the least odor.
