lowering his weapon, rode peacefully alongside of his intended victim.

Captain Phin Glover's mule was found grazing behind the butte, in the
midst of the gallant Captain's dishevelled baggage, while the robbers had
vanished by a magic which seemed quite natural in this scenery of
grotesque marvels. They had unquestionably seen or heard their pursuers;
but how had they got into the bowels of the earth to escape them?

Thurstane presently solved the mystery by pointing out three crouching
figures on the flat cap of stone which surmounted the shales and marl of
the butte. Bare feet and desperation of terror could alone explain how
they had reached this impossible refuge. Texas Smith immediately consoled
himself for his disappointment as to Thurstane by shooting two of these
wretches before his hand could be stayed.

"They're nothin' but Injuns," he said, with a savage glare, when the
Lieutenant struck aside his revolver and called him a murdering brute.

The third skulker took advantage of the cessation of firing to tumble down
from his perch and fly for his life. The indefatigable Smith broke away
from Thurstane, dashed after the pitiful fugitive, leaned over him as he
ran, and shot him dead.

"I have a great mind to blow your brains out, you beast," roared the
disgusted officer, who had followed closely. "I told you not to shoot that
man." And here he swore heartily, for which we must endeavor to forgive
him, seeing that he belonged to the army.

Coronado interfered. "My dear Lieutenant! after all, they were robbers.
They deserved punishment." And so on.
