There were several moments of agonizing suspense; the Spaniard who had shouted out was evidently awaiting a reply. And then suddenly he repeated his challenge.
"Who goes there?"
And a moment later came a sound of hurrying footsteps.
"What's the matter?" Clif heard a voice demand.
He was the only one in the party who understood Spanish, and knew what was said. But it was plain to the rest that it was a conversation between a sentry and an officer.
"I heard a footstep, senor capitan!" cried the man. "Quidada! Take care! It's very near."
There was a moment's pause.
"You must be mistaken," said the officer.
"I am not mistaken," repeated the man firmly. "Santa Maria, my ears do not deceive me. You said to be watchful, for you have heard firing."
To that the Americans had listened in trembling silence; but the next made them jump. "I will light this lantern," said the officer.
