“Damn the knife!” interrupted Calhoun, unbuttoning his coat. Then drawing forth the proscribed weapon, and flinging it to the farthest corner of the saloon, he added, in a tone of bravado, intended to encowardice his adversary. “I sha’n’t want it for such a spangled jay-bird as that. I’ll fetch him out of his boots at the first shot.”

“Time enough to talk when you’ve done something to justify it. Cry boo to a goose; but don’t fancy your big words are going to frighten me, Mr Calhoun! Quick, gentlemen! I’m impatient to put an end to his boasting and blasphemy!”

“Hound!” frantically hissed out the chivalric Southerner. “Low dog of an Irish dam! I’ll send you howling to your kennel! I’ll—”

“Shame, Captain Calhoun!” interrupted the major, seconded by other voices. “This talk is idle, as it is unpolite in the presence of respectable company. Have patience a minute longer; and you may then say what you like. Now, gentlemen!” he continued, addressing himself to the surrounding, “there is only one more preliminary to be arranged. They must engage not to begin firing till we have got out of their way?”

A difficulty here presented itself. How was the engagement to be given? A simple promise would scarce be sufficient in a crisis like that? The combatants—one of them at least—would not be over scrupulous as to the time of pulling trigger.

“There must be a signal,” pursued the major. “Neither should fire till that be given. Can any one suggest what it is to be?”

“I think. I can,” said the quiet Captain Sloman, advancing as he spoke. “Let the gentlemen go outside, along with us. There is—as you perceive—a door at each end of the room. I see no difference between them. Let them enter again—one at each door, with the understanding that neither is to fire before setting foot across the threshold.”

“Capital! the very thing!” replied several voices. “And what for a signal?” demanded the major. “A shot?”

“No. Ring the tavern bell!”

“Nothing could be better—nothing fairer,” conclusively declared the major, making for one of the doors, that led outward into the square.
