Nature has built the largest stadium in the world for the sport-loving population of Cleve- 

 land, Ohio. Over one hundred thousand persons watched this baseball game, and thirty 

 thousand more could have been accommodated 



A Natural Stadium Which Holds 

 One Hundred and Thirty Thousand 



THE largest stadium in this country 

 is not a product of engineering 

 skill but the work of nature. More 

 than one hundred thousand persons, the 

 largest crowd that ever witnessed a 

 baseball game, was assembled in this 

 great bowl recently without taxing its 

 capacity. It is estimated that it could 

 accommodate one hundred and thirty 

 thousand persons. 



The natural stadium is part of a city 

 park in Cleveland, Ohio, and all athletic 

 events which take place there are free 

 to the public. It is almost a perfect 

 amphitheatre. The large field, suitable 

 for all kinds of athletic games, is almost 

 completely surrounded by hills inclined 

 at just the right degree to accommodate 

 spectators. At one end there is a break 

 in the hills that affords a convenient en- 

 trance and parking space for auto- 

 mobiles. 



Fifty Thousand Aviators 



TO the average American, the aero- 

 plane is still a wonder, a miracle, 

 a creation of magic. In Europe men 

 have become so accustomed to it, that 

 children now talk of becoming "avia- 



tors" as they would of becoming "police- 

 men." Counting both pilots and ob- 

 servers, there are more than fifty thou- 

 sand men now in Europe, in daily 

 flights above ground. The number in- 

 creases from day to day, and before the 

 war is ended it is possible that the num- 

 ber will reach one hundred thousand. A 

 hundred thousand human beings taken 

 to the air every day — and only six years 

 ago Glenn H. Curtiss made his first long 

 flight down the Hudson River — a won- 

 derful feat chronicled in the press of the 

 world ! 



Paper from Grass 



TERMINATING a series of experi- 

 ments, the Department of Agricul- 

 ture has recently announced that it is 

 possible to manufacture a first-grade ma- 

 chine finished printing paper from zaca- 

 ton grass, which grows in great profu- 

 sion from California and Texas south- 

 ward to the Argentine Andes. 



This grass is harvested for the sake 

 of its roots. These are made into brushes 

 of various sorts, and are frequently 

 known as broom root grass. At the pres- 

 ent time the tops of the grass are allowed 

 to go to waste. There is reason to be- 

 lieve that from these a satisfactory pa- 

 per-making material may be developed.
