Appleton, Victor. Tom Swift and His Submarine Boat. McLean, VA: IndyPublish.com, [1910] 2002. ISBN 1-4043-3567-6.
As usual, I read the electronic edition of this novel published in the Tom Swift and His Pocket Library collection at this site on my PalmOS PDA in random moments of downtime over a couple of months. I've posted an updated electronic edition which corrects typographical errors I noted whilst reading the book, the fourth installment in the original Tom Swift saga.

It's delightful to read a book which uses the word “filibuster” in its original sense: “to take part in a private military action in a foreign country” but somewhat disconcerting to encounter Brazilians speaking Spanish! The diving suits which allow full mobility on the abyssal plain two miles beneath the ocean surface remain as science-fictional as when this novel was written almost a century ago.
