A Labor-Saving Dump Car. It 

 Does Away with Shovels 



►OTH speed in unloading and 

 economy of labor are se- 

 cured with a new dump-car 

 which throws material to either 

 side of the track. The side of 

 the car turns down when dump- 

 ing and serves as an apron to 

 carry the material clear of the 

 track and cars. In this respect 

 the car differs from any other 

 made, as it discharges the ma- 

 terial in such a position that no 

 labor whatsoever is required for 

 shoveling. ;As the regular train 

 crew can handle the dumping apparatus, 

 the services of section gangs, regular 

 laborers, or extras are not required for 

 dumping. The speed of unloading also 

 releases the rolling stock quickly; for the 

 cars may be immediately returned for 

 loading, instead of being held for about 

 ten days as formerly. 



A car is dumped by compressed air, 

 and one car or an entire train can be 

 dumped at one time. The dump car 

 is all steel, and the body is supported on 

 rockers. Equilibrium is provided for by a 

 flat place in the center of each rocker sur- 

 face. In dumping, the box ; is merely 

 tipped off this flat surface. When the box 

 is empty the low center of gravity Causes 

 it to roll back into place. The car may 

 be dumped to either side by making a 

 slight adjustment. A link fastens the car 

 in the upright position, and a separate lock 

 makes it impossible to dump the contents 

 to .the wrong side. 



On a single division of an Eastern road 

 the cost of removing waste was reduced by 

 the side dump cars from $100 to $37 a day. 



How "the Lion and the Lamb" Lie 

 Down Together in the Motion Pictures 



"TylTHAT chances actors take!" you 



VV may exclaim when you examine 

 the photograph above, showing a man and 

 a lion, with a none too pleasant expression, 

 in a hollow log together, each apparently 

 unaware of the presence of the other. 



It seems a pity to spoil the effect of 

 such a good thriller by - 

 telling the truth about the 

 filming. The lion alone 

 was taken during one ex- 

 posure of the film. When 

 he had bowed himself out 

 of the log and back into his 

 cage the man was allowed 

 to take the center of the 

 screen, or rather of the log, 

 and was photographed in 

 proper relation to the lion 

 on the second exposure of 

 the same film. But on the 

 screen, of course, they both 

 appear in the log at the The side dump car in operation. The side piece acts as 



same time. an apron to carry the waste material clear of the tracks
