Mr. Average Healthy Man's 

 Enormous Appetite 



AN average man who has seen seven ty- 

 L five years of life has eaten an amount 

 of food equal to some fifteen hundred times 

 his own weight. One hundred and ten tons 

 of food he has consumed, of which the 

 bread alone, if it could be piled separately, 

 would occupy a space equal to that of a 

 good-sized building. The vegetables on 

 reappearing would fill a train three miles 

 in length and the bacon w^hen placed end 

 to end in single slices would stretch along 

 a line four miles long. The reappearance 

 of five tons of fish and one-fifth of a ton 

 of cheese would surely haunt him, while 

 twelve thousand eggs, ten thousand pounds 

 of sugar and fifteen hundred pounds of salt 

 would put in their claim. And he has 

 smoked no less than 250,000 cigarettes. 

 Let's hope he has saved the coupons. 



The Sandwich Man As an Ally of the 

 Telephone Companies 



WHEN a disastrous fire swept through 

 Paris, Texas, not long ago, utterly 

 destroying more than fourteen hundred 

 homes and many business houses of the 

 cit>% the telephone system was badly 

 crippled. Not only were private lines 

 destroyed, but on account of the scat- 

 tering of families into temporary- quar- 

 ters all over the city it was almost im- 

 possible to locate any one called over 

 the long distance wires. An ex- 

 change tvas connected tem- 

 porarily to handle such calls, 

 but the problem was to find 

 the person wanted. 



It was finally solved by 

 employing the sandwich-man 

 idea. Several boys were en- 

 gaged to carry blackboards 

 sandwich fashion, on which 

 were written in large letters 

 the names of the persons 

 wanted. Primitive as was 

 the plan (dating back to 

 1780, to the fourth Earl of 

 Sandwich, who originated 

 the idea) it cleared up the 

 situation until the tele- 

 phone lines were restored. 

 The sandwich boys were 

 not of the usual silent 

 type but whistled and 

 called to every passerby 

 to read the sign.

 telephone companies of Paris, 

 Texas, were forced to resort

Convert Your Bicycle into a Motor- 

 cycle with This Detachable Motor 

 ANEW bicycle motor, so small that 

 it reaches only from the top of 

 the front wheel to the handlebars, 

 is to be placed on the market 

 for those who wish to convert 

 their bicycles into motor- 

 cycles. The motor, a com- 

 plete gasoline engine in minia- 

 ture, has a flywheel and a 

 muffler. It is clamped to the 

 wheel by a strong side-fork, so 

 that a steel traction-pulley 

 presses down upon the tire at 

 its center. 



The gasoline-tank on one 

 side is balanced by the weight 

 of the flywheel on the other, 

 so that the pulley-groove is 

 pressed down uniformly 

 across the tire. The ignition 

 system consists of a small 

 spark-coil and two dry cells, 

 which are stored in a small 

 case suspended from the 

 horizontal bar of the bicycle 

 frame.
