Average water evaporated, liters per kg of coke ( lbs. perlb. of coke). In both of the above tests it was found impossible to keepthe boiler pressure at all constant. The maximum speed on a down grade was 60 km ( miles)an hour. An average speed of km ( miles) an hourwas maintained both on the outward and on the return journey. y u n f n 65* T.

Reducing these figures to per tonmile we find that the consumption of load water for the lowaverage speed tests varied between the following limits: Coke 267 lb. to .4025 lb. per ton mile Water lbs. to lbs per ton mile The Wiirtemberg State Railways has for some years beenexperimenting with Serpollet cars. The experiments with their first Serpollet car were com-menced in February, 1897; the whole apparatus, as far as en-gines and boiler were concerned, was supplied by the Serpollet, of Paris. The car was a four-wheel one driving axle; the wheel bases of two of the cars testedwere 4 m (13 ft. V/2 ins.) and m (15 ft. 1 in.), respectively,and contained thirty-three and forty seats, with standing roomfor eight passengers on th
