One of the greatest pleasures in life so far denied to most men is to witness the constantly changing scenery of under-sea life in tropical waters. It has been one of the great desires of my life to explore the bottom of the southern seas. All of my submarine work has been in the more northern waters, covering the Chesapeake Bay, Long Island Sound, on the Atlantic coast north of Virginia Beach, and in the Baltic Sea and Gulf of Finland. The range of vision in any of these waters did not exceed forty feet, but that has been sufficient to create a zest for more. The beauties of under-sea life can be described only by a poet. It is impossible for me to convey to the imagination the wonderful beauty of some of the under-sea gardens when seen through the windows of a submarine automobile. Imagine, if you can, these under-sea gardens with masses of vegetation, swaying to the current and waves of the sea, of a great variety of form and color and with myriads of many beautiful and variously colored fishes swimming among them, with perhaps a background of a wonderful coral reef of fantastic shapes, with the octopus, or devil-fish, lurking at the mouths of dark caverns, and the long, gray man-eating shark, like a ghost now and then flitting within one's range of vision. Instead of the sky above you, you see a scintillating mirror which reflects the sun's rays as they penetrate the clear blue waters and strike the white sands and are reflected back to this under surface of the water and are then re-reflected back in multitudinous rainbows of color. Such sights await the tourist of the future who visits some of the southern seas, with the further privilege of seeing some of the old wrecks, many of which have been lost since the days of the Spanish galleons by striking on some of these same coral reefs, and whose skeletons now lie at their base. I have built for my own use a combination house-boat and exploring submarine automobile, and hope in the near future to explore some of the southern waters along the Florida coast and in the Caribbean Sea; also, later to build larger submarine automobiles to enable "sight-seeing" parties to see some of the beauties of "Davy Jones' locker."
