��Inclined platforms leading to the roof of the goat-house were built to indulge the climbing instincts of the goats
Wild Goats Live on the Roof of Their Building
THE efforts of wild animals in captivity to follow their natural instincts were amusingly illustrated recently by the antics of some wild goats in a Western Zoological Park.
Six of the goats were captured and a loghouse, surrounded by a high wire fence, was specially con- structed for them in the" zoological park. For a long time, how- ever, they were ill at ease and made des- perate efforts to scale the wire fence. Find- ing this impossible, they finally attempt- ed to climb up the ' sides of their log house. This taught their keeper that they were not trying to es- cape but were merely following their in- stinct for climbing. So he built inclined platforms leading to the roof of the build- ing. As soon as these were finished the goats scampered to

��If You Use This Lock,
Don't Forget the
NEW lock for the automobile works on a simplified form of the combination principle commonly used in safes. By a combination lock the self-starter, battery and magneto circuits are con- nected and disconnected within a steel case on the instrument board. With the same operation a valve in the gasoline lead is opened and closed by means of a steel wire in metal housing extending from the lock on the in- strument board to a valve which is located in the gasoline lead.
When the driver wants to lock his car he gives the operating handle, mounted just below the combination knob, a half turn to the off position and all ignition is instantly disconnected and the gasoline cut off. When the driver wants to unlock his car he simply turns the
���combination knob to the three-number combination he has set and all the igni- tion is connected and the gasoline valve opened.
The lock is capable of more than 87,000 distinct changes in the combination, so that it would waste time for even an ex- pert to find the right one unless he knew it in advance.
When a car is locked there is no loss of gasoline through dripping, for there is no pressure on the carbureter. The lock also prevents "back- fire" setting a car afire; for when "back- fire" occurs you simply turn the lock off and the carbure- ter is disconnected.
