TRAVELING AT HIGH SPEEDS HELE-SHAW.

an hour. A Stanley steam car, 127 miles an hour, and a Benz car 

 has done 127 J miles an hour. 



The maximum recorded speeds of a railway were on the experi- 

 mental line of Messrs. Siemens, on the Berlin-Zossen High Speed 

 Railway, where a speed of rather more than 130 miles an hour was 

 attained. The electric current employed was 10,000 volts, 400 horse- 

 power motors being used. On the Marienfel-Zossen experimental 

 line, the speed attained with 250 horsepower was apparently rather

less, though in that locomotive four motors were employed, the 

 current being, as in the other case, 10,000 volts. The lantern dia- 

 grams are a picture of the vehicles actually employed, and of the 

 track on which the experiments were made. As a set-off against the 

 sober engineering pictures, I show a picture taken from an American 

 motor journal, illustrating a motor vehicle and locomotive at top 

 speed, the former passing on a level crossing in front of the latter.
