THE D. M. STEWARD MFG. COMPANY, Chattanooga, Tenn., reports a very large demand for its lava Insulators; and states that its business for the month of October was the largest in its history. The manufacturers claim for this lava insulation that its durability and insulating properties are equal to those of porcelain or mica; that it can be fused only by the intense heat of the electric arc, and that it is not soluble in any known acid. It can be turned, cut, threaded or molded accurately into any shape, it is claimed, and is therefore well adapted for the most exacting portions of delicate electrical work. The company states that within four days from the receipt of a model, drawing or blue-print, it will furnish a manufacturer with a dozen samples of its product, and within four days from the receipt of an order it can furnish 10,000 complete pieces of any kind of lava insulation.
