DEMONSTRATION
 OF ESSENKAY
Practical Use of the New Tire Filler on Phoenix Streets; What the "Air Substitute" Looks Like, and Its Handling

Essenkav, the newly invented sub- stitute for air for automobile tires has arrived in Phoenix and been given a thorough test in a new twenty four hundred pound car
 The first shipment, which was to have consisted of g. sets of the com pound was skimped owing to the big demand for it in Los Angeles, but enough came to fill several sets of castings, for preliminary try outs. The demonstration before the writer was UnqualifieIIy satisfactory. If it had been a guess. those who rode on Els senkay would have said it was air. There was absolutely no way of telling that the old time filler of motor car shoes had been discarded for a mater ial in all ways as good, and in many, avoiding the difficulties encountered through the use of the fluid so apt to escape from confinement at unhandy times, and stall the car for lack of something elastic to take up the great shocks that come from collision with bumps and holes.
 It has been said the weight of Essen kay in the tires makes the running heavier, but as far as that goes, there was no appreciable difference in the riding, no logginess, nor any slowing due to the presence of the composition. It was also argued the heavier sub stance would make brakinS difficult, would cause skidding and a rough stop, but to demonstrate the fallacy of that contention. the driver caused the ma chine to go through all the evolutiOns of actual driving through traffic. Swinging aside as if to avoid a wagon the car crossed car tracks and changed from a comparatively high speed to a lower one by means of a quickly ap- plie,I brake, with an entire absence of any of the predicted phenomena. The car behaved in a way exactly natural to a gasoline propelled vehicle of mod ern make, showing off the magic com pound in it's big rubbers to the com plete satisfaction of those whose curi- osity led them to try a ride over it.
 After testing the cars riding quail ties on several kinds of road surfaces the party went to the garage where temporary quarters have been installed for packing castings with Essenkay and made the acquaintance of the sub stance itself. It comes in lengths abou a ward long The first shipment is fo tires three inches in diameter, so thu rolls are approximately three feet b. three inches Covered with light wo ven mesh of cotton, the stuff appear to be a bundle of light elastic rubber, looking material, little heavier than tn air it is designed to replace and ever. bit as springy to the touch, as a wei pumped up tire.
 The manner of packing is interesting The wheel is clamped to a low stano the tire turned wrong side out, an lengths of the E1ssenkay roll lai around the circumference. Of course the roll does not fit exactly, so to fl the shoe so all the interstices are pad ,Ied out and the pressure distribute evenly. short sections are cut with
 vavv bladed bread knife and packed l until the proper pressure is attained
 When the weight af a car is put O the tire. The Essenkay is pressed int the exact shape of the inner tube, tn use of which is obviated by the no cscaping feature of the compound. is the practice to use from seventy eighty pounds pressure of air in tir and this can be supplied easily b packing in Essenkay closer CT not. FC heavy trucks, great pressure is use
