Large Robot Diving Bell to Explore for Lost Treasure
AFTER fifteen years of patience and industry, Harry L. Bowdoin, marine engineer and inventor of Saybrook, Connecticut, has finally perfected diving equipment which will permit him to descend to depths of over 600 feet in search of lost treasure and new scientific data.

Millions in Gold FREE for the TAKING!
The author of this article tells you exactly where you can find $125,000,000 in gold—and it’s all yours the moment you lay hands on it. The difficulty is that the gold is buried in the hulks of wrecked ships several hundred feet beneath the sea. Inventors of diving contrivances are staging a frantic race to see who will be first to retrieve the golden fortunes.
by DONALD GRAY
STORIES of buried treasure, hidden by Lafitte or Kidd or concealed somewhere about the old homestead by the wealthy farmer who was afraid of banks, usually have this one feature in common: although the existence of the treasure is well-authenticated and widely credited, nobody knows exactly where the hidden doubloons have been laid to rest.

Hoover’s Decision Terminates Career of Presidential Yacht, Mayflower
WHEN President Hoover recently decided to forego the use of the yacht, Mayflower, shown in the photo below, to reduce national expenses $300,000 yearly, he again changed the status of a vessel that has known nothing but change in its 33 years of existence.
Designed as a private yacht, it spent only a short time in that capacity. It was active as a dispatch boat of the “mosquito fleet” in the Spanish-American war, and serving as the presidential yacht since 1905, has been subject to the whims, habits and fancies of five different government heads.
“Airwheel” Flies by its Revolution
MANY attempts have been made, both before and after the invention of the airplane, to develop a craft which should really fly. The ornithopter, or bird-wing craft, has not been successful in its motion, any more than mechanical devices which simulate walking. The bird, like the man, has a great many controls in its muscular equipment, which are difficult to imitate in a machine. However, during the past few years, the idea of a revolving wing has been attracting more and more inventive effort. Read the rest of this entry »
This Amphibian Row-Mobile Travels Equally Well on Land or Water
Land or water—it makes no difference to the passengers of this combination boat and automobile. The “amphibile” is propelled by the rowing motion of the occupants. The front wheels are used to steer both on land and in water.
Floating Airports of the Sea
Ocean stepping-stones in the form of floating seadromes bid fair to cut down the hazards of trans-Atlantic flights.
Regular airplane service across the Atlantic is brought a step nearer reality by the projection of plans for a series of floating landing fields which can be anchored at intervals of a thousand miles between America and Europe, affording a safe place for passenger carrying planes to come down for refueling and mechanical attention.

Shackleton the Pioneer
by W. H. TURNER
Technical Editor Encyclopedia BrittanicaTWENTY years ago Shackleton set out for Antarctica with a shipload of equipment. Today a million dollar expedition with four ships and four airplanes is exploring the same ground—but in what a different way! Old and new methods of exploration are graphically contrasted in this authoritative article.

Sea-Going Diner Pays No Taxes
BY TOM MCCAHILL
SAILORMEN of New York waters don’t die of thirst any- more, thanks to a new enterprise that pays no rent and no local taxes.
No, sir. When they’re a little parched they twist an ear until they pick up a few musical horn-toots. Then they jump up and wave their arms. A slick cruiser draws alongside. “What’ll you have?” asks a smiling cookie. Read the rest of this entry »
Seaplanes Launched From Deck of Ship on Canvas Slide
MAIL-STEAMERS not equipped with expensive catapults for launching airplanes at sea will welcome the invention of the Kiwull watersail, so named after its inventor, which is shown in operation in the above drawing. The invention is simple, consisting of a length of canvas 100 feet long and 32 feet wide which is unrolled from the stern of the ship, as shown, to form an incline down which a seaplane can be lowered to the water. The canvas is held taut by water pulling against a “drogue” or net at the trailing end. Seaplanes can also return aboard deck by this means.
Ocean Skimmer for Atlantic
Modern Mechanics’ cover this month depicts new adaptation of Alexander Graham Bell’s hydrofoil principle, showing new Atlantic “stepladder” liner.
AT LAST the “step ladder boats,” as the hydrofoil speeders planned by the son of Dr. Alexander Graham Bell have been called, are to make a bid for laurels as the fastest method of crossing the Atlantic. Read the rest of this entry »
A Boy-Powered Submarine
By DEE ENGEL
Many of the towns lying along the Platte River are close to sand pits — depressions made when sand is dredged. These fill up with clear water and the sandy sloping bottoms make these various pools ideal for swimming and other water sports. Don Webb lives in Kearney, Nebraska, and of course there is an abundance of these miniature lakes close by; so Don built a sub which is manned by a couple of boys. And to say that they have a lot of fun with it is putting it mildly.

The Sea-Gem: a 100mph Air-Cushion Ship by 1963
By JAMES JOSEPH
NON-ELECTION year 1963 may nevertheless bring a spectacular inauguration.
Some time next year, America’s first air-cushion ship, the Sea-GEM (for sea-going ground effect machine) may streak New York to London on her maiden “flight.”
Riding 3 to 6 ft. above the waves on a frictionless cushion of air, the giant 100-ton craft will be propelled at better than 100 mph by four jet-prop pusher-type engines.
Part ship, part plane, and wholly revolutionary, the Sea-GEM promises its 100 first-flight passengers some surprises.
