It is geared to the shafting by means 

 of a silent chain drive. The gener- 

 ator and pump are driven from the 

 shaft by an ordinary belt system. 

 The lights, more than a hundred in 

 all, are supplied by direct current 

 without the necessity of storage bat- 

 teries. However, there is a surplus 

 of lights, so that in the near future 

 both water wheel and fountain are 

 to be illuminated at night. Under 

 the waterfall and dam is a milk house. 



A modern water wheel

 site furnishes current for

His Lighting Bill Is Twenty-Five 

 Cents a Month 



AN old water wheel on the estate of 

 Ji\ Frank B. Moore, at Trenton, N. J., 

 is made to run an electric light 

 plant and to pump water for three 

 acres of trucking ground at an ap- 

 proximate expense of twenty-five 

 cents per month for lubricat 

 ing oil — the water doing the 

 rest. 



The property now oc 

 cupied by Mr. Moore 

 was formerly a deserted 

 mill site. The old 

 stone residence was 

 erected in 1775. The 

 miniature mill seen in 

 the illustration is built 

 on the old mill site, 

 the lower floor being 

 used as a pumping sta- 

 tion, machine shop and 

 garage, and the upper 

 story as a recreation 

 room. 



The wheel is ten feet 

 high and three feet wide. 

 It is mounted on roller 

 bearings and develops 

 about ten horsepower. 



Testing the strength of the rubber in a 

 hot water bottle. It was used in this 

 case as a life rope without accident 



Maltreating a Rubber Water 

 Bottle to Test Its Strength 



the photograph 

 shown below is 

 thriller intended 

 for the motion picture 

 screen. It is merely a 

 record of a test made 

 by a rubber goods 

 manufacturing com- 

 pany to find out how 

 much strain their hot 

 water bottle would 

 stand. 

 First a girl was allowed to have fun 

 with it after it had been filled with water, 

 by using it as a punching bag. But she 

 did not punch it about in the ordinary 

 way. She wore metal "knuckles" such as 

 the highwaymen in the dime 

 novels use. After she had 

 i tired herself out without af- 

 fecting the bag in the least, 

 she turned it over to four 

 heavy - weights. Each of 

 them took a corner and 

 pulled with all his might. 

 Still the bag held. 

 Several tests were 

 made but the final 

 one was most excit- 

 ing. The man who 

 made it risked his 

 life. He weighs one 

 hundred and sixty 

 pounds; but with only 

 the bag as a rope he 

 allowed himself to be 

 pulled up from a window 

 to the roof of the build- 

 ing — and there was no 

 accident to himself or 

 to the bag: After this 

 test the official "OK" was 

 given without reserve.
