And sure enough. These Cheyennes and Sioux were wise. For a year and a half they had been watching the white man’s iron horses and big thunder wagons advancing onward into the buffalo country; and they had learned a number of new wrinkles. They were no longer afraid of the strange “medicine.” For here they were, boldly tackling the cars, laying hands upon them, climbing aboard—and setting the brakes!

Their almost naked figures, outlined against the sky, atop the cars, tugged and hauled at the brake wheels. The brake-shoes ground harshly; fumy smoke floated from underneath, as the locked car-wheels slid on the rails; the engine, with throttle open, roared vainly. Out from the cab darted Fireman Bill Sweeny, mounted the tender and, skipping to the first car, revolver in hand, hung to the ladder while he raked the tops beyond.

“Sharp-shooters give it to ’em!” Pat yelped. The carbines of the track-layer gang banged hopefully.

The Indians ducked and swung off to the farther side. The brakeman was out of the caboose. He lay flat upon one end of the train, the fireman lay flat upon the other end; and hitching along they began to kick the brakes free. The galloping Indians peppered at them, but failed to hit them.

“Be ready, lads,” Pat ordered. “Skirmishes wid the guns, first. The rist of us wid the picks. We’ll run for it, and meet the train. Jist a minute, now.” And—“Oh, the divils!” he added. “Charge!”

A squad of the Indians, dismounted, had thrown a tie across the track. A wild volley from the carbines had not stayed them. Engineer Richards, plunged in his own steam cloud, evidently did not see the tie; he came on, pushing Jimmie Muldoon’s loaded truck before him; the white horse tried to bolt and fell with a broken neck just as the rope parted; the smoke-stack was atilt, and spitting smoke and steam from a dozen bullet-holes; but twitched by the roaring engine, the train moved faster and faster.

Up sprang the men, with a yell. The line of skirmishers, carbines poised, charged—charged in splendid order, like soldiers, aiming, firing, running. With picks and sledges and even spades the other men also charged, behind the skirmishers; bending low and shouting, yes, laughing in their excitement.

“The tie! Look out for the tie on the track!” they hallooed.

Terry had nothing to carry, and he was fast on his feet. Never had he sprinted so, before. The first thing he knew, he was through the skirmishers and legging on by himself, while the bullets hummed by him and every instant the distance between tie and truck was lessening. All his eyes and thoughts were on that tie. If the engine—his father’s engine—rammed it with the rail-loaded truck—wow!

He lost his hat—he heard whoops and shouts and excited Shep’s wild barking—the Indians on his side were swerving off, before the carbine bullets—but the engine was thundering down upon him, he saw his father’s astonished grimy face peering from the cab and he glimpsed the cars behind spewing naked figures. Then he dived for the tie. He barely had time to lift one end when the truck struck the tie, hurled it to the left and him to the right; but they both fell clear, for as he picked himself up the box-cars were rumbling by, jerking to the sharply braked engine.
