The group of porcelain and glass insulators shown in the accompanying illustration exhibits a few of the most important types of these goods as made at the establishment of Fred M. Locke, at Victor, N. Y. The capacity for resisting high pressures is stated in connection with the different types. This petticoat type of insulator was designed and patented by Mr. Locke, and is in use on many high tension lines in this country, including the 11,000-volt transmission line between Niagara Falls and Buffalo.

Mr. Locke claims to produce only high class goods, and from observations made on several different occasions, it would seem difficult to suggest any additional precautions, facilities or methods that would be necessary to sustain this claim. Mr. Locke being an expert chemist, makes a chemical test of every batch of clay bought, so that he is sure of his mixtures, and sure that the goods when they leave the kiln are of a uniform and safe grade. For the purpose of making these tests he has fitted up a large room in his dwelling house with an elaborate chemical outfit, and here samples of all clays and kaolins required, both native and foreign, are brought, so that no clay dealer is able to palm off upon this establishment an inferior material. Mr. Locke's new catalog, No. 4, describes in detail his high insulation line material.
