We have based this upon the Boothroyd tire, ofEngland, as our general type, and have improved up-on it very much, as we took the English type cushiontire a year ago and improved upon that. We con-struct it with a complete and perfectly air-tight tubefully equal in all respects to the air tubes of the wrappedtires. Upon this we build the canvas protector,and then the tread of somewhat tougher and strongerrubber than the air tube, vulcanizing the whole to-gether in an endless, seamless tire, which we place PNEUMATIC AND CUSHION TIRES. 263 our full confidence on as the simplest tire in use, theneatest in appearance, least liable to get out of order,and the easiest to repair effectually, should it requireit at any time.

We have devised a valve which is of correspond-ingly simple and effective construction. We believethat we have had more experience with the generalsubject of pneumatic tires than any other of the largemanufacturers of this country, and we have never feltmore confident than we do to-day that we have madethe right choice.
