(p. 85) The gas interests had been dealt a number of recent setbacks even before Edison’s announcement of a newly successful variant of electric light. An “enormous abandonment of gas” by retail stores in cities, who now could use less expensive kerosene, was noticed. The shift was attributed not to stores’ preference for kerosene but as a means of escaping “the arrogance of the gas companies.” Arc lights had now become a newly competitive threat, too. The previous month, Charles Brush had set up his lights in an exhibition hall in New York and then added a display in Boston. Sales to stores followed in several cities; then, as word spread, other establishments sought to obtain the cachet bestowed by the latest technology. William Sharon, a U.S. senator for and energetic booster of California, retrofitted the public spaces of his Palace Hotel in San Francisco with arc lights that replaced 1,085 gas jets.
