diving-buoys which are attached to the wreck. After the water is pumped out of them, they become buoyant enough to raise it. This is a scientific animated drawing.
A-294-b Cause of Slides, Panama Canal Bray Paramount

A-312-a The Light that Never Fails Bray Pictograph
A lighthouse is an extremely lonely place, the monotony is only broken by the changing moods of the sea. A single gas mantle of 1500 candle power is the only source of light. Revolving prisms magnify the light of the mantle to 300,000 candle power and make it visible 30 miles away, but even this powerful light cannot always prevent disaster.
A-312-b Air Pressure Bray Pictograph
The air in which we live and breathe has a pressure of approximately 15 Dounds per square inch. This amounts to many tons on a human body and would crush us if our bodies did not exert a similar pressure and prevent it. A demonstration of the result, when the atmospheric pressure is not supported by equal pressure from within, makes this scientific reel extremely interesting.
A-313-a How the Cowboy Makes His Lariat
Bray Paramount
Pedro Leon, a Texas ranchman, shows how American cowboys make their cinches and lassoes. The ranchman's own cayuse supplies most of the material. The horse-hair, which is stronger than any other fibre, is spun into long strands and the strands in turn spun into a rope. The hair cinch and lariat are prized for their elasticity and strength. The hair lariat is often used at night by the cowboys to encircle their camps to keep the rattlesnakes away, as no rattlesnake will cross a hair rope.
A-314-a The Key to Beauty Bray Paramount
The only sure road to beauty is good health. Numerous physical exercises are performed by a physical culture trainer, showing how to make one's figure more perfect. The trainer, a young lady, is dressed in gymnasium tights, but there is nothing objectionable in the demonstration.
