230 BLACK-TAILED DEER. 
‘* So we will read it, Uncle!” said Jane; 
*“* and I can tell you, here, some pretty lines, 
which I learned the other day, about the 
migration of troops of the Wild Deer, when 
winter comes on, and their numbers are too 
great, so that they can find but little to eat :— 
‘ The genial years increase the timid herd, 
Till wood and pasture yield a scant supply ; 
Then troop the Deer, as at a signal word, 
And in long lines o’er barren downs they hie, 
In search what food far valleys may supply.’” 
The Black-tailed Deer, of which there is 
a specimen in the Museum, at Bruton-street, 
is a native of North America, where, along 
with another species, it is called Chevreuil, 
or Roe, by the French Canadians; and 
_ Jumping Deer, by the English of Hudson’s 
Bay. It is found only to the Westward of 
105° west longitude, and goes no farther 
north than the banks of the river Sadcatche- 
wan. When roused, this Deer makes off by 
a series of uninterrupted bounds, raising all 
its feet from the ground at once, and vibrat- 
ing its black-tipped tail from side to side. 
The height of a full-grown Doe has been 
found to be rather less than two feet and 
a half.
