308 SCIENCE OF HOME AND COMMUNITY 



Since then tremendous progress has been made in air 

 navigation in the distances covered, in the speeds attained, 

 in the heights reached, and in the number of passengers 

 carried. 



Distances. During the latter part of 1909, Wilbur Wright 

 flew with a passenger for an hour and a half. Henry Farnam 

 remained in the air four hours. In 1910 Paulhan flew from 

 London to Manchester, a distance of 183 miles, with only 

 one stop, and won the prize of 10,000 pounds offered by the 

 Daily Mail of London. In America, Curtiss flew from 

 Albany to New York, a distance of 150 miles, with only one 

 stop. In 1911 long flights, varying from 800 to 1000 miles, 

 were made in various parts of Europe. During the latter 

 part of 1916 an American woman, Ruth Law, made a con- 

 tinuous flight from Chicago to Hornell, New York, a dis- 

 tance of 590 miles. The entire trip from Chicago to Gov- 

 ernor's Island, near New York City, a distance of about 

 900 miles, was made in a little less than nine hours at 

 an average speed of about 100 miles an hour. In 1916 

 Lieutenant Marchal made a non-stop flight of 812 miles 

 from France to Poland. And now some of the experts 

 prophesy that a trans-Atlantic flight will be made in the 

 near future. 



Speed. There has also been a wonderful gain in the 

 speed attained. In 1912 a speed of 72 miles an hour was 

 reached. In 1916 in America, Mr. Carlstrom traveled a 

 distance of 315 miles at the rate of 137 miles an hour, or 

 more than two miles a minute. From 47 miles an hour to 

 137 miles is the progress made in seven years. Army air- 

 planes are reported to have traveled at the rate of more than 

 150 miles an hour. In January, 1918, two men in a plane 

 driven by liberty motors were reported in the newspapers to 

 have traveled from Dayton to Cleveland, Ohio, a distance 

 of 215 miles, in i hour and 15 minutes. This is at the rate 

 of 172 miles an hour.
