He pulled the cord of the air-whistle, and after the stop stood by in sour silence while the crew repacked the hot box. Since he had made the car inspectors carefully overhaul the truck gear in the Denver station, there was no one to swear at. Olson bossed the job, did it neatly and in silence, and no one said anything when the fireman, in his haste to be useful, upset the dope-kettle and got its contents well sanded before he had overtaken it in its rolling flight down the embankment. Ford turned away and climbed into his car at the dope-kettle incident. There are times when retreat is the only recipe for self-restraint; and in imagination he could see the general manager's special ticking off the miles to the eastward while his own men were sweating over the thrice-accursed journal-bearing under the "01." Now, as every one knows, hot boxes, besides being perversely incurable, are the sworn enemies of high speed. At forty miles to the hour the journal was smoking again. At forty-five it burst into flames. Once more it was patiently cooled by bucketings of water drawn from the engine tank; after which necessary preliminary Olson spoke his mind. "Ay tank ve never get someveres vit dat hal-fer-damn brass, Meester Ford. Ay yust see if Ay can't find 'noder wone." And he rummaged in the car lockers till he did find another. Unfortunately, however, the spare brass proved to be of the wrong pattern; a Pullman, instead of a P. S-W. standard. Olson was a trained mechanic and a man of resources, and he chipped and filed and scraped at the misfit brass until he made it serve. But when he climbed again to the cab of his engine, and Ford swung up to the steps of the car, the white headlight eye of an east-bound freight, left at a siding a full hour's run to the rear, came in sight from the observation platform of the laboring special. These were the inauspicious beginnings of the pursuit; and the middle part and the ending varied only in degree. All the way up to midnight, at which hour a station of a bigness to supply a standard brass was reached, the tinkered journal-bearing gave trouble and killed speed. Set once more in running order upon its full quota of sixteen practicable wheels, the special had fallen so far behind its Denver-planned schedule as not only to be in the way of everything else on the division, but to find everything else in its way. Ford held on stubbornly until the lead of the train he was trying to outrun had increased to twelve hours. Then he gave it up, directing his crew to turn the train on the nearest "Y," and to ask for retracing orders to Denver. After which he went to bed in the state-room of the borrowed car, and for the first time in his experience was a man handsomely beaten by the perversity of insensate things.
