Forty Miles an Hour on 

 the Water 



A BOAT has been dL-signcd 

 by D. N. Brown, of 

 ('■rand Ha\X'n, Mich., whirli, 

 on test runs, has attained 

 a speed of forty miles an 

 hour. The body of thr 

 craft is made of thin gal 

 vanizcd iron o\er a basswond 

 framework two feet wide and 

 twent\- feet long. Two gal- 

 vanized iron air-tanks are 

 attached to an outrigger five 

 feet from the rear end on 

 both sides. When the four-cylinder 

 motor, set in the rear, whirls a six-inch 

 prtjpellcr, the prow rises out of the water 

 a:;d the craft skims along like a huge 

 bird over the surface, the entire weight 

 resting on about three feet of the stern. 

 The two tanks maintain the equilibrium. 



The boat has pro\ed a success in all 

 ways and the in\entor believes, with 

 an improved design, that he will have a 

 craft capable of making sixty miles an 

 hour without being crowded. 



It is e\-ident that the inventor reduces 

 skin friction as much as he can, for 

 which reason he is able to travel at high 

 speed in his boat.

Forty miles an hour is the claim of the inventor of this 



craft, which partially rises out of the water when 



it is under full speed 



of this rakish craft. Lie down comfort- 

 ably upon the keel of the ship (which 

 should be so laid as not to interfere un- 

 duly with an\of your spinal peculiarities), 

 grasp the conical rudder-control with 

 both hands, set your gaze intently upon 

 your goal and pedal for dear life. 



The rudder is a ball and socket affair 

 that will steer the ship in any direction 

 in the water. The pedal-propeller- 

 gearing is at a two to one ratio to insure 

 speed, and the pontoons ,1 .1, are 

 inflated to the required buoyancy; i.e., 

 to float about one-third out of the water. 



With a score of these one-man scouts 

 darting across the water a battleship's 

 squadron might anchor in perfect secur- 

 ity and laugh at the deadly submarine. 

 Or they might be hitched tandem, 

 so that you may invite your fair lady to 

 take the air on the ocean and sa\e not 

 only the carfare to the nearest beach, 

 but bath-house hire as well. 



The timid swimmer can now go through all the motions 



of swimming while being supported by a concealed

yacht has been evolved. It is indeed a 

 peace ship — a one-piece — one man, semi- 

 submersible. .\ glance at the anatomical 

 chart appended, will explain the action 



New York is the World's 

 Luxury Market 



LONDON, the world's 

 central market for the 

 sale of luxuries of every de- 

 scription, has been practical- 

 ly closed and New York has 

 taken its place. ("ustom 

 House records show that the 

 imports of the "luxur\' class" 

 ha\e increased enormous- 

 ly, particularly in the items 

 of precious stones and works 

 of art. As a single example, the Amer- 

 ican automobile industry's imports of 

 crude rubber in the past year amounted 

 to more than Si I i,ooo,000.
