west to Milwaukee, thence southwesterly through Cedar Rapids 

 and Des Moines to Omaha, thence southeast to Kansas City, 

 and east through Jefferson City, St. Louis, and Indianapolis 

 to Cincinnati; thence it will turn in a northerly direction and 

 go through Columbus and Cleveland; thence west to Toledo, 

 north to Detroit, and west again back to Chicago. The aero 

 clubs of Ilhnois, Michigan, Milwaukee, Kansas City, St. Louis, 

 Indiana, Cincinnati and Chicago will cooperate with the Aero 

 Club of America. 



The circuit will be divided into sections with intermediate 

 controls. Each section will end at a large city where aviators 

 will stop overnight. As aviators will be arriving at various 

 hours one day and leaving the next, each city will practically 

 have two full days of flying. Stops will be made also at inter- 

 mediate cities, where there will be a "control" or station where 

 aviators will land and stop for a limited time. 



The circuit is to be open to licensed pilots of all nationalities 

 who will be free from injunction under the Wright patents, 

 arrangement having been made with the Wright Company to 

 this effect. 



Among the prizes proposed to be given are : For first and 

 second machines to reach the end of each section ; for the 

 American built and flown machine first to complete the circuit; 

 for minimum horse power required to complete the course; first 

 to complete course with a passenger; best wireless demonstra- 

 tions ; greatest number of wireless messages delivered ; best 

 maps and topographical descriptions, drawn en route ; first aero- 

 plane fitted with automatic stabilizer to complete the circuit; 

 most completely equipped machine to complete circuit; the ma- 

 chine completing the circuit having intact most of its oflicially 

 stamped parts. 



In drawing the regulations to govern this event, the commit- 

 tee in charge will endeavor to make it a conclusive test of 

 everything that goes to make aeroplaning practicable. The 

 program outlined above show^s that the circuit will include 

 many useful and interesting features never before embraced in 

 a similar event. Especial efforts will be made to bring out 

 the various qualities of the aeroplane which are of practical 

 use.

THE GREAT AMERICAN AIR CIRCUIT NEXT FALL. 



AERL'\L circuit races have been held in France, Germany 

 and Great Britain with much acclaim and great success, 

 particularly in France ; but the Aero Club of America, with the 

 assistance of various western clubs expects to hold a great 

 international circuit in this country, next September, that will 

 be more important in many ways than any of those held abroad. 

 In the first place, it will be about 700 miles longer, as the pro- 

 posed route* is 1.810 miles. Then the prizes will aggregate 

 about $100,000, including the grand prize of $25,000. 



The international race for the Gordon-Bennett Aviation 

 Trophy will take place near Chicago early in September, and 

 this will bring to our shores practically all the noted flyers of 

 the world. This 1,800-mile international circuit will be held 

 immediately thereafter, so that the same contestants can take 

 part in both events. The circuit will start at Chicago, go north-
