Daring Diver Feeds Diving Dolphins
An underwater picnic at which a diver hand-feeds a school of porpoises while at the bottom of an outdoor tank, is a novel stunt performed daily at an aquarium in Marineland, Fla. Dressed in full underwater regalia, the diver enters the tank carrying a wire basket full of small fish. Descending to the bottom, he sits on the tank floor twelve feet below the surface and feeds the aquarium’s dolphins by hand. The unusual photograph above was snapped through a window in the side of the tank as one of the graceful creatures paused only long enough to snatch up a mouthful.
Depression Spurs Lost Gold Treasure Hunts
by BENNETT LINCOLN
Treasure long lost under ocean waters is the golden loot which is luring half a dozen expeditions to recover it, spurred on by the urgent need for gold developing out of the present economic conditions. Charles Courtney, master locksmith who battled death to recover $60,000 from a sunken treasure ship, tells his story of high adventure in this fascinating article.
GOLD, down through the ages a symbol of wealth, has now become so doubly priceless that we in this country may not even legally possess it! Beyond a doubt that is one reason why so many expeditions are at work today recovering the gold of other agesâ€”gold which went down weeks or years or centuries ago, and since that time has been resting uselessly in the mud-filled hulks of ancient galleons.
Engineer Makes 6-Mile Sewer Voyage
A SIX-MILE trip through deadly gases in the North Outfall sewer in Los Angeles, Calif., was made by Rufus Brown, assistant superintendent of sewers. The hazardous trip was made to determine the condition of the tunnel walls which had been exposed to the sewer’s powerful erosive gases since 1922. It was the first inspection trip ever made of the interior of a main sewer line.
A special unsinkable skiff that was propelled by the swift flow of the sewer stream was used. It carried special lights, a two-way radio, a camera and photoflood bulbs. Heavily insulated electric wiring was used to offset the possibility of a spark causing an explosion of the sewer gases. Brown wore a rubber suit fitted with an oxygen mask and a two-hour oxygen supply tank.

SIMPLE RULES, OUTLINED BY A CHAMPION, WILL HELP YOU TO BE A BETTER DIVER

FAMOUS OLYMPIC DIVER AND STAR IN BILLY ROSE’S AQUACADE
GLIDING along the springboard in easy strides, you bounce down onto the tip and feel the springy plank catapult you skyward. High over the water, your body under perfect control, you suddenly whirl in mid-air and knife down into the blue water below. Knowing you’ve made a perfect dive, you bob to the surface, your ears ringing to the applause of the crowd. That’s the thrill of diving.
But if your experience is limited to occasional bellyflops from the rim of a pool or swimming hole, you probably feel that springboard diving is a difficult sport to learn. Well, it isâ€” and it isn’t. I’ve been at the game for sixteen years, and I know I still have plenty to learn. But picking up the fundamentals of basic dives such as the swan or the graceful back dive, is far from an impossible task even for a rank beginner. And once you’ve mastered the simpler dives, the more complicated ones are only a matter of determination and practice.
SOUTH-SEA Diving Goggles
By HI SIBLEY
These fine goggles were made by a Hawaiian. Experts consider this type more satisfactory for serious diving and continuous use than the ordinary rubber variety
WITH a little care and patience, you can construct diving goggles exactly like those used by the spear fishermen of the South Seas and expert Hawaiian divers.
A Diving Helmet from a Water Heater
THEY go down to the sea in old water heaters along the Atlantic coast these days, now that some young man with a leaning toward aquatic sports has proved how easy it is to make an excellent diving helmet from a metal water heater which will enable its wearer to walk comfortably on the sea floor 35 feet and more below the surface. A few feet of garden hose, two pairs of bellows, a couple of valve boxes and a cylindrical metal boiler of the type used in most homes for heating water, are the essentials for building one of these helmets.
This would be really usefull for fighting all those underwater fires…
New Mask for Diving, Fire Fighting
QUITE Frankenstein-like is the Los Angeles fireman, shown at the left, who is wearing the last word in fire fighting equipment. The device is a self-contained breathing apparatus designed to purify any atmosphere from the interior of a burning building to a flaming oil well fire. It may also be used under water to a depth of approximately 16 feet.
BUILDING a DIVING Helmet
Improvement follows improvement in the design of home made diving helmets as amateur divers become more and more acquainted with their use. This one of Hoag’s is the last word in helmets so far published by good old M-M.
ALL the thrills of exploring the lake bottom are yours with this simply constructed diving helmet; and, if you do not dive too deep, you are in no particular danger, either. Besides its use in recovering lost outboard motors at a substantial profit, the helmet will give you one of the most interesting experiences of your life; for until you have breathed and walked at leisure under water, you have missed something. It will take a good deal of nerve to go down the first time, but after that it will just be fun.
Glass Cooky Jar Becomes Diving Bell
DIVING enthusiasts for more than a year, the twin brothers, Joe and Jerome Maurice, 17-year-old high school students of Fond du Lac, Wis., invaded their mother’s pantry for their 1935-version diving helmet.
A heavy glass cooky jar was selected to form the bell of the helmet, and thick sheet copper was sealed to this to form the breast plates and shoulder supports for the jar.
Several improvements in construction were added to the new model. The air valve was placed within easy reach of the right hand, with the air hose entering the helmet from below to prevent kinking. The helmet may be swiftly slipped off in the event of accident below water.
The greatest advantage of the cooky jar diving bell is that it permits full vision in all directions with ample safety. Air is supplied through a two-cylinder pump at a pressure of 30 pounds per square inch. At a depth of 35 feet, the helmet functioned perfectly.
The helmet the twins used in 1934 was made from the end of a water tank, with a top air valve and welded port window for observation. The imperfections of this helmet led to the invention of the new one.
