North America. We refer to the moose or elk. Although 

 this animal is the largest of the deer, it is not without its 

 enemies. During the summer and in the depth of winter 

 the moose is well able to take care of itself. It is powerfully 

 built, with massive .horns and a gait which carries it over 

 the ground at no mean pace. 



At the end of the winter, when the thaw sets in, this 

 enormous deer must make provision against its enemies ; 

 its very size and weight are disadvantageous, for at every 

 step it sinks knee-deep into the soft snow. The time has 

 arrived for the moose to build a "yard," which consists 

 of a rampart of snow, sometimes four or five miles in 

 diameter, within which the snow is trodden down in a 

 series of paths which form a veritable network running 

 in all directions. Inside the "yard" the herd of moose 

 dwell in perfect safety till the winter snows have passed 

 and -warmer weather sets the animals free from their 

 enforced confinement.
