Interior, Nut & Bolt Fastener Co. Plant. so far as is known, when Dr. Frederick H. Milloner, experi-mental electrician, Union Pacific R. R., Omaha, turned on thelights in the building, the impulse being sent from the FortOmaha wireless tower, six miles distant. This demonstrationwas made possible through the courtesy of Colonel Glassford,Signal Corps, U. S. A. The wireless impulse operated on aspecially constructed coherer (which is very delicate andwill receive the faintest impulse) similar in construction tothat used a year ago on the eletrically controlled (by wire-less) truck in the shop yards of the Union Pacific, at Omaha.By means of a large solonoid switch, which is closed whenthe impulse passes through the cohorer, seventy-five horsepower were turned on and the Auditorium lighted. Bymeans of a similar mechanism the power was turned off andthe operation repeated several times—in other words, thelocal circuits in the Auditorium were closed by wirelessimpulse from Fort Omah
