A Perfect Megaphone Shaped 

 Like a Ram's Horn 



A BOSTON physician, Dr. Edmun.l 

 D. Spear, has invented a megaphone 

 which is constructed on tlie theory that 

 the original liorn — the ram's horn — 

 was and still is technically correct for 

 sound reproduction. His megaphone is 

 curved insteatl of the straight funnel- 

 like shape of most other instrumenis, 

 and one of the most interesting and useful 

 features about it is the ability to use it 

 without having it interfere with one's 

 vision. Owing to the technical construc- 

 tion of the curved horn the volume of 

 sound obtained is also much more satis- 

 factory. In adilition to this the tone 

 is clearer and the enunciation more tlis- 

 tinguishable. The best musical horns 

 have the shape of a ram's horn. 



The ingenious water cooling and 

 fuming attachment for the electric

 fan 



Perfuming and Cooling the Air with 

 an Electric Fan 



A CLEVER and useful attachment for 

 the electric fan, designed Ijy a 

 Los Angeles inventor, consists of a tin 

 wheel which can be hooked on any 

 electric fan, and which will increase its 

 cooling capacity many fold. 



The spokes or propellers of this wheel 

 are made of fine mesh screen. The 

 lower part of the wheel whirls in a tank 

 which is filled with cold water. The 

 electric fan causes the screen propellers 

 to revoh-e, and they dip into the little 

 tank, throwing up a small amount of 

 water on the upward turn. 



The air is sent through the water and 

 is cooled, purified and cleaned. Perfume, 

 a disinfectant, or a medicated li(]uid 

 may be used instead of water. 



The simple ram's horn is the original 

 Adam of all our present-day megaphones 



Why the Gasoline Engine Keeps the 

 Farmer Boy at Home 



ONE of the jobs on the farm, which 

 has had as much to do in creating 

 tile ilesirc of the farmer boy to leave 

 and go to the city, has been the chore 

 of sawing wood. It is one job that 

 seemed never to be ended. With the 

 advent of the gasoline engine, the work 

 of sawing the wood, not only for farm 

 consumjition but for commercial pur- 

 poses, has been changed to one of great 

 fascination, if not pleasure, in compari- 

 son with its former drudgery.
