mascot copper company DOS cabezas arizona yucca arizona october 4 1912 gentlemen your tur letter of inquiry regarding the truck aruck to hand our experience with trucks in the past has been very expensive and about annoying 15 months ago the writer brought an 3 ton truck every ton truck we hauled with this cost in the truck neighborhood of fifty dollars per ton our haul is 25 miles the was mostly in the repair shop then one of the head men of our company met the representatives of the company they induced him one of their 5 ton to buy trucks under a written guarantee to do certain things the experience peri ence was the same with this truck mostly in the repair shop and no freighting this truck the writer cretu returned arned after two months trial we even sent to the factory for a man on condition that if the truck would do the work they guaranteed R we would pay their man 1000 per day until all freight that was lying at the R station was hauled to mine we had the material for a concentrating mill lying a cent there the factory man was here nearly two months and we did not pay him we then got a this truck has been on the job now 72 days without a breakdown we hauled all the machinery to mine with this truck we W e have a five mile grade that ranges from 10 to 12 per cent fifteen miles of desert road with a three to six per cent we cross six sandy washes we had never any trouble on account of sand the sand will soon pack under the wide and big diameter wheels the writer is now driving the truck himself in order to get acquainted with every detail of the truck in order that he can break in new men when the old ones get too independent the truck consumes from 17 to 20 gallons of gasoline a round trip depending on the size of load distance 50 miles lubricator oil 1 gallon the heaviest load we hauled to mine was a little over 5 tons this the truck hauled without trouble regarding the brakes of this truck you can hold any kind of load on any grade with either foot brake or emergency the has also an air brake on engine or the engine can be made into an air brake the other tw Q brakes are made very strong and heavy so that there is no chance of them giving away on any grade A slight pressure on foot brake will hold any load there is no doubt that the truck is the only truck for the arizona desert so far built the writer has seen many other makes tried but all were more or less a a failure too much gingerbread work about them and too small diameter wheels the writer has no interest in the sale of any truck but his experience has been so unpleasant and expensive with trucks that when he found one that did the work and stayed on the job instead of in the repair shop he cannot say too much for such a machine you cannot make a a mistake
