246 The White Goat 



road from Kamchatka, their ranges upon this 

 continent but partially coincide, and even where 

 both animals are established and flourishing in 

 the same zone, their localities within that zone 

 are so capriciously separated as to baffle even the 

 explanation that one drives the other out. 



It would seem that they can stand equal cold ; 

 both are to be found in Alaska, as might be 

 expected from the manner of their emigration. 

 And beginning with Alaska (one authority, R. 

 Lydekker, " The Royal Natural History," London, 

 1898, the best authority I have found for co- 

 herence and completeness, names latitude 64° as 

 the northern limit), we find goat and sheep alike 

 plentifully distributed as we come south. But 

 only for a certain distance. If the Northwest be 

 plain like a picture in your mind's eye, you can 

 recall how in the far North the Cascades and 

 Rockies are intermingled, and how, as we come 

 down through British Columbia to our own soil, 

 they gradually separate, slope apart, so that by 

 the time they reach the latitude of Portland, 

 Oregon, a wide, flat domain lies between them. 

 Both have slanted inland; but while the Cascades 

 are only some hundred and sixty miles from the 

 Pacific coast, the Rockies are away over in Idaho
