The skilled mechanic or electrician has the advan- 

 tage over the pick-and-shovel man in rifle shooting 



command of the hands by her work that 

 made her good with the pistol the first day. 



The trained gymnast has the edge on 

 the untrained man. He may require a 

 little time to get used to sighting accurately, 

 but he has command of his body, he has 

 learned to make any set of muscles 

 respond when desired. 



The man of untrained hands, the 

 "working man," regardless of his 

 hard biceps and triceps and del 

 toid, will have more trouble 

 mastering rifle shooting in 

 all its phases. Such men 

 find little trouble in holding 

 the rifle like a rock in the 

 prone position by the aid 

 of the sling, because mus- 

 cular strength and a little 

 knack in sling adjust- 

 ment are all that are 

 required. But when it 

 comes to rapid fire and 

 snap shooting, they lack 

 the command of eye and 

 nerve and muscle. This 

 is the story in theory. 



The way to learn how 

 to shoot the rifle is to 

 shoot the rifle — doing the 

 preliminary work with the 

 empty gun, and then with 

 the humble .22, which 

 shows bullet strike, but 

 does not cover up by heavy 

 recoil the sin of "yanking 

 the trigger," which is un- 

 doubtedly the cardinal 

 fault of the beginner.

How About that Third Cup of 

 Coffee for Breakfast 



IN the matter of cutting down 

 the daily food consumption to a 

 reasonable minimum, why not be- 

 gin with coffee? Although coffee 

 is a true stimulant, it is essentially 

 a drug and has in itself no food 

 value. Its effects in the main are 

 due to an alkaloid, caffeine, which, 

 it is believed, is a heart stimulant. 

 In a sound, healthy individual, 

 doses of caffeine equivalent to that 

 obtained from one cup of strong 

 coffee produce no noticeable effect 

 except a slight nervousness. Doses 

 equivalent to one and one-half 

 cups produce marked unsteadiness 

 in muscular and mental work. 

 Doses sufficient to produce any real stimu- 

 lative effect raise the blood pressure, some- 

 times dangerously, and stimulate the action 

 of the kidneys in a manner considered by 



physicians to be harmful. 



A minaret of a Turkish mosque? 

 No; a power-house smokestack 

 in beautiful Salt Lake City 



The Most Ornamental Smokestack 

 in the World 



ALT LAKE CITY has perhaps 

 the most ornamental smoke- 

 stack in the world. Since it 

 adorns the top of a building in 

 which smokeless fuel is burned , 

 no one unacquainted with 

 the plant and the purpose 

 of the stack would be likely 

 to suspect its function. 

 It resembles the minaret 

 of some Turkish mosque, 

 but it belongs to a power- 

 house. It stands six 

 feet high, the lower half 

 being of stone construc- 

 tion with the smoke vent 

 through the center. The 

 upper half is extended as 

 a tubular steel chimney 

 surmounting a crown- 

 shaped dome of metal. 

 This dome serves as a roof 

 for the observation plat- 

 form for visitors, greatly 

 adding to the appearance 

 of the tower and complet- 

 ing the illusion. The entire 

 city and landscape for miles 

 around can be seen from 

 the platform.
