Hamlin’s face became grave, his eyes also, turning toward the river.  The sun was already sinking low in the west, and the Indians, gathered in council out of rifle-shot, were like shadows against the glimmering water beyond.

“They ’ll try us again just before dark,” he affirmed slowly, “but more cautiously.  If that attack fails, then they ’ll endeavor to creep in, and take us by surprise.  It’s going to be a clear night, and there is small chance for even an Indian to hide in that buffalo-grass with the stars shining.  They have got to come up from below, for no buck could climb down this bluff without making a noise.  I don’t see why, with decent luck, we can’t hold out as we are until help gets here; those fellows who rode away will report at Canon Bluff and send a rider on to Dodge for help.  There ought to be soldiers out here by noon to-morrow.  What troops are at Dodge now?”

“Only a single company—­infantry,” replied Moylan gloomily.  “All the rest are out scouting ’long the Solomon.  Damned if I believe they ’ll send us a man.  Those two cowards will likely report us all dead—­otherwise they would n’t have any excuse for runnin’ away—­and the commander will satisfy himself by sendin’ a courier to the fellers in the field.”

“Well, then,” commented the Sergeant, his eyes gleaming, “we ’ve simply got to fight it out alone, I reckon, and hang on to our last shots.  What do you make of those reds?”

The three men stared for some time at the distant group over their rifles, in silence.

“They ain’t all Arapahoes, that ’s certain,” said Moylan at last.  “Some of ’em are Cheyennes.  I ’ve seen that chief before—­it’s Roman Nose.”

“The big buck humped up on the roan?”

“That’s the one, and he is a bad actor; saw him once over at Fort Kearney two years ago.  Had a council there.  Say!” in surprise, “ain’t that an Ogalla Sioux war bonnet bobbin’ there to the right, Sergeant?”

Hamlin studied the distant feathered head-dress indicated, shading his eyes with one hand.

“I reckon maybe it is, Moylan,” he acknowledged at last gravely.  “Those fellows have evidently got together; we’re going to have the biggest scrap this summer the old army has had yet.  Looks as though it was going to begin right here—­and now.  See there!  The dance is on, boys; there they come; they will try it on foot this time.”

He tested his rifle, resting one knee on the seat; Moylan pushed the barrel of his Winchester out through the ragged hole in the back of the coach, and the little Mexican lay flat, his eyes on the level with the window-casing.  The girl alone remained motionless, crouched on the floor, her white face uplifted.
