"Nobody knows fer sure, but it must have been a derelict an' a sunken one at that 'cause the lookout swears as how he was on his job an' that there wasn't a thing in sight an' Toby's a good man all right."
"Probably you're right," Bob agreed.
At that moment two men came running from the stern of the ship and Bob noticed that they wore the uniforms of first and second mates.
"Hasn't the captain come back yet?" the first mate asked anxiously.
"Not yet," one of the sailors replied.
"It's strange. We left him below and he didn't have as much of the ship to look through as we did, and he ought to be here."
"He'll have to hustle or he'll be too late," the second mate declared. "She's going to take her last dive before many minutes."
As he finished speaking all the lights suddenly went out. Fortunately it was moonlight and they could see for some distance.
"Water's got up to the dynamos," the first mate announced.
"And what's more the wind's getting up too," the other mate said.
