"It can, but it don't," was Ben's reply.

"Ah, but you never sailed off the coast of Madagascar, did yer?" demanded Bill.

"No, I can't say as I ever did," replied Ben.

"Wall, then," triumphantly cried Bill, "you don't know what a pesky wind that Madagascar one is."

How long this argument, which the boys listened to with some amusement, might have gone on is hard to say, probably all night, if Ben had not suddenly cut it short by springing to his feet with an exclamation:

"Come on, shipmates!" he exclaimed, "stop gamming and get a move on and snug down this yer awning if you don't want to lose it. Billy, you open the self-baling scuppers in the cockpit, my lad, and Lathrop and Harry, you get out forward and double lash all that top hamper."

"Why, Ben, what's the matter?" asked Frank, "the sea is just as smooth as it has been all day and the sun is shining."

"Well, it won't be in a half an hour," replied the old salt, pointing southward. "See that cloud?"

He indicated a tiny purplish bit of vapor floating against the distant blue like an argosy. "There's wind in that cloud or my name's not Ben Stubbs," he concluded.

Bluewater Bill nodded his assent.
