Casey was just thinking that they would soon run out of gas, and that he would then have a fighting chance, when he was startled almost into believing that he had spoken his plan.
"I told you there's a twenty-gallon tank on this car; well, it holds twenty-five.

I've got a special carburetor that gives an actual mileage of twenty-two miles to the gallon on ordinary desert roads.

I filled 'er till she run over at Victorville--and I notice you're easy on the gas with your drivin'.

Figure it yourself, Casey, and don't be countin' on a stop till I'm ready t' stop." Casey grunted, more crestfallen than he would ever admit.

But he hadn't given up; the give-up quality had been completely forgotten when Casey's personality was being put together.
