Harnessing a Fighting Lion for the Films

THE photographs above were taken during the filming of an-adventure-in- the-jungle photo play, when a lion was to be pictured running. The "jungle" was mere painted canvas, but the lion — he was very much the real thing! With mighty struggles and protests, he was lifted by a derrick right over the top of his cage and on to a stationary, split platform on the stage. His feet rested upon two boards which were alternately given a back and forward motion. The result was a furious struggling lion.

��To hold the animal steady he was strapped to this heavy iron sup- port on the stationary platform

��Three Shots with a Single Shell. It's Intended for Airships

A KIND-FACED Britisher, not sat- isfied with having one try at a Zeppelin or an airplane with each shot from an anti-aircraft Powd< gun, has designed and pat- ented a progressively explod- ing shell which has three exploder charges in three sep- arate compartments, arranged to burst at different time in- tervals. If the first explosion is too early the second or

the third may find the mark. Each compartment charge gives off a different colored light for the in- formation of the gunner, who knows the time inter- val between the charges and the time for which the first com- partment is set to burst. By comparing the position of the red or blue or white flare with the position of the airship, the gunner corrects his range.

This performance is made possible by a shell having three separate and heavy com- partments, each with its load of shrapnel and bursting charge. They are con- nected only by a small fuse passage extending from one to the other.

A time fuse which is carried in the head, connected by a tube through the shell with the charge in the com- partment at the base of the shell, fires this base charge at what the gunner hopes is the psychological moment Fuse for obtaining the desired re-

passage sm t. But if this happens to be a poor choice of time, the fuse crawls up to compart- ment two, and sets off that also, with its different colored light. If nothing decisive happens then,* the gunner finally lets the third charge go in the shell head.
