The following note met his puzzled gaze.
"DEAR CAPTAIN: Please come over and see me at once.

Something serious has happened at the bank.

I need your aid and advice.
"Yours, "ROB BLAKE." "Hum! The signature is typewritten, too," mused Rob.

"What kind of a joke is this?
I don't know, but I'll bet anything that Jack Curtiss is at the bottom of it." "Well," demanded the captain, "what is it, a bit of gammon?
I'll keel-haul the man as did it if I can find him." "It looks like a hoax of some sort," admitted Rob, sorely puzzled; "but I can't for the life of me see the object of it.

Come into the house a minute, captain, and we'll try to figure it out." Seated beneath the lamp in the library of his home, Rob scrutinized the letter closely, but could find absolutely no indication about it to betray who could have typewritten it.
"How did you come to receive it ?" he asked suddenly.
"Why, old Hank Handcraft come out in that crazy launch uv his and guv it ter me," rejoined the captain.
