I have no idea what's going on here. The Dolphin is stuck? He's building a ship under water? Caption: "Frank mounted the timbers over the Dolphin's bow, and began work with his saw. He worked away with all his might to sever the heaviest timber when held the head of the Dolphin. It was no light tast, for the timber was of stoutest oak, but Frank kept steadily at work."


Didn't he invent one last issue? That was No. 88, Vol IV. This issue is No. 89. Does no one remember these things? Did Frank, like Tom Swift, get a concussion every issue, and was hence unable to remember long-term accomplishments? I Shall Build a Submarine Boat!

Eh - boss, uh, you already - ahh, nevermind. Whatever keeps him busy.
