It may be of interest to note the results of tests made upon a lot of rubbish. In a certain run of ten hours, during which a total weight of 102,531 pounds of rubbish was used, the average horse-power developed was 232.7. One pound of rubbish fur

It won't take many months to cover the expense of equipping this valuable plant, for, besides saving that $10,000 a year previously expended in disposing of the city's rubbish, there will be the doing away with the enormous coal bill contracted every year for the lighting of the Williamsburg bridge and vicinity.

Herrgott is making rugs and carpets, curtains, hangings and other so-called thermopile fabrics, which, when properly connected with a supply of electric current, will keep an apartment at almost any desired temperature.

In appearance and texture the electricheating rugs can hardly be distinguished from those of ordinary manufacture. They are woven of wool and the other usual materials, about an invisible and finely divided skeleton of specially prepared metallic threads, which is autoresistant, exactly like an incandescent electric light filament. These threads are very supple, do not buck': in weaving and present a very large heating surface in proportion to their small diameter. All the fabrics are woven so as to produce a fixed degree of temperature from a given current and there is no danger, whatever, of their being destroyed or

even injured by overheating.
