Figure 39. — Passengers changing cars on Edoux elevator at inter- 

 mediate platform. (From La Nature, May 4, 1889, vol. 17, p. 361.) 



Figure 40. — Worthington tandem compound steam pumps, at base 

 of the Tower's south pier, supplied water for the Edoux system. 

 The tank was at 896 feet, but suction was taken from the top of the 

 cylinders at 643 feet; therefore, the pumps worked against a head of 

 only about 250 feet. (From La Nature, Oct. 5, 1B89, vol. 17, p. 293.)
