ength of the safety-chains; thus far, but no farther.

Halkett stood up.

"It's up to you, Danforth," he said, raising his voice to be heard above
the pounding roar of the wheels. "You're the youngest and lightest: get
down on the 1010's brake-beam and unhook those chains."

The secretary looked once into the trap with the dodging jaws and the
backward-flying bottom and declined the honor.

"I can't get down there," he cried. "And I shouldn't know what to do if I
could."

Once more the superintendent exhibited his nerve. He had nothing at stake
save a desire to defeat Callahan; but he had the persistent courage of the
bull-terrier. With Bucks and the secretary to steady him he lowered
himself in the gap till he could stand upon the brake-beam of the 1010's
tender and grope with one free hand for the hook of the nearest
safety-chain. Death nipped at him every time the engine gave or took up
the slack of the loose coupling, but he dodged and hung on until he had
satisfied himself.

"It's no good," he announced, when they had dragged him by main strength
back to a footing in the narrow vestibule. "The hooks are bent into the
links. We're due to go wherever that damned Irishman is taking us."

forward vestibule untenable. When they were driven in, Bucks and the
receiver went through to the rear platform, where they were presently

The governor gave the word.

"Wait," he said; and the four of them clung to the hand-rails, swaying and
bending to the bounding lurches of the flying car.

Mile after mile reels from beneath the relentless wheels, and still the
speed increases. Station Donerail is passed, and now the pace is so
furious that the watchers on the railed platform can not make out the
signals in the volleying wake of dust. Station Schofield is passed, and
again the signals, if any there be, are swiftly drowned in the gray
dust-smother. From Schofield to Agua Caliente is but a scant ten miles;
and as the flying train rushes on toward the State boundary, two faces in
the quartet of watchers show tense and drawn under the yellow light of the
Pintsch platform lamp.

The governor swings himself unsteadily to the right-hand railing and the
long look ahead brings the twinkling a
