MacMurtrey, tearing along toward the scene, yelled like a crazy man:

"Block her! Block the wheels! You—you——" His voice died in a gasp. "D'ye hear!" he screamed, as he got his breath again. "Block the wheels!"

And the Polacks, the Swedes, the Hungarians and the What-Nots, scared stiff, screeched and jabbered, as they watched the tank-car, gaining speed with every foot it travelled, sail down the grade. And MacMurtrey, too late to do anything, stopped dead in his tracks—his face ashen. He pulled his watch, licked dry lips, and kind of whispered to himself.

"Number Three 'll be on the foot of the grade now," whispered MacMurtrey, and licked his lips again. "Oh, my God!"

Meanwhile, down the grade around the bend, Sammy Durgan yawned, sat up, and cocked his ear summitwards.

"Now what the devil are them crazy foreigners yelling about!" complained Sammy Durgan unhappily. "'Tis always the way with them, like a cageful of screeching cockatoos, they are—but being foreigners mabbe they can't help it, 'tis their nature to yell without provocation and——"

Sammy Durgan's ear caught a very strange sound, that mingled the clack of fast-revolving wheels as they pounded the fish-plates with a roar that hissed most curiously—and then Sammy Durgan's knees went loose at the joints and wobbled under him.

Trailing a dense black canopy of smoke, wrapped in a sheet of flame that spurted even from the trucks, the oil-tank car lurched around the bend and plunged for him—and for once, Sammy Durgan thought very fast. There was no room to let it pass—on one side was just nothing, barring a precipice; and on the rock side, no matter how hard he squeezed back from the right of way, there wasn't any room to escape that spurting flame that even in its passing would burn him to a crisp. And with one wild squeak of terror Sammy Durgan flung himself at his handcar, and, pushing first like a maniac to start it, sprang aboard. Then he began to pump.

There were a hundred yards between the bend and the scene of Sammy Durgan's siesta—only the tank-car had momentum, a whole lot of it, and Sammy Durgan had not. By the time Sammy Durgan had the handcar started the hundred yards was twenty-five, and the monster of flame and smoke behind him was travelling two feet to his one.

Sammy Durgan pumped—for his life. He got up a little better speed—but the tank-car still gained on him. Down the grade he went, the handcar rocking, swaying, lurching, and up and down on the handle, madly, frantically, desperately, wildly went Sammy Durgan's arms, shoulders and head—his hat blew off, and his red hair sort of stood straight up in the wind, and his face was like chalk.
