"By midnight."
"Very well. Listen now."
The speaker's manner changed; fixing his big eyes upon the sailor's lesser orbs, he continued:
"A few stadia north of Sidon there is what may be called a bay. It is about four miles across. Two little rivers empty into it, one on each side. Near the middle of the bend of the shore there is a well of sweet water, with flow enough to support a few villagers and their camels. Do you know the bay?"
The skipper would have become familiar.
"You are well acquainted with this coast," he said.
"Do you know of such a bay?" the passenger repeated.
"I have heard of it."
"Could you find it at night?"
"I believe so."
