"What sort of a fellow?"

"Quiet; steady; works on his farm like a horse, week in and week out; never speaks out of his turn, and says little enough when his turn comes."

"That sort is often the deepest," observed Mr. Rogers sententiously, and puffed. "And Saaron Island there, close by the Roads, lies very handy for a little illicit work."

"You are right, so far," the Commandant admitted; "and history bears you out. In the old kelp-making days, when half-a-dozen families lived on it, Saaron gave more trouble than any two islands of its size."

"It's none the less handy for being deserted." Mr. Rogers drew out a penknife and meditatively loosened the tobacco in his pipe.

"Handier. But you are wrong in suspecting Tregarthen; that is, unless you have good tangible evidence."

"I don't say that it amounts to much, but it's tangible. In fact, his boat is lying here, just now, close under the Keg of Butter."

The Commandant turned on his heel and took a pace or two towards the window, to hide his perturbation and give himself time to consider.... Vashti's boat! And Vashti on the premises at this moment! What was to be done? How on earth could he get her away?

"You discovered this yourself?" he found himself asking.

"No; I happened to be in the Watch House with the chief boatman checking the store-sheets, when Beesley, whose watch it is, came in and reported. I see what you're driving at. Your own boat is lying under the Keg of Butter, as everybody knows, and you suggest that I am duffer enough to mistake her in the darkness for a boat at least two-foot longer."
