these artificial conditions ; special mention may be 

 made of the fine show of aoudad at the Diisseldorf 

 Zoological Garden, where an enormous troop of 

 some sixty animals scramble in picturesque confusion 

 about an artificial ruined castle. The New York 

 Zoological Park also contains a fine " mountain 

 sheep hill," consisting of a ridge of pink granite ; it 

 is 500 feet long and 25 feet high. Shaded by trees 

 at one end, the other is fully exposed ; it is partly 

 covered with green turf, has five roomy caves 

 constructed in it, and is subdivided by light fencing 

 into six enclosures for aoudad and similar animals. 

 The new Zoological Park at Stellingen, near 

 Hamburg, also has a good series of artificial 

 mountains amongst its other attractions. The rocks 

 rise from 80 to 150 feet, and with their living 

 tenants present a fine appearance, though the animals 

 do not ascend to the summit of the peaks. In the 

 Barbary sheep one has a zoological paradox ; a beast 

 difficult enough to find (or to capture when found) 

 in its native mountains, and inhabiting the 

 burning climate of Africa, not only tolerates the 

 change of air and scene but breeds with such success 

 in Europe as to become a familiar menagerie exhibit.
