CONE-BEARERS. 101 



The Alaska Cypress comes down from the Alaska 

 Islands along the mountains, as far south as Mt. Hood, 

 and here, too, is the great thick-barked Western Tamarack, 

 and a little farther northward, the Woolly Tamarack. 



The Tamarack Pine and the Mountain Pine are com- 

 mon, and near Roseburgh, in Oregon, is the original lo- 

 cality where Douglas discovered the Sugar Pine still a 

 valuable product of the region while here and there 

 detached groves of a form of Yellow Pine carry that inval- 

 uable species far up the valley of the Fraser. The cross- 

 ranges of mountains also carry many of the trees men- 

 tioned eastward to Idaho and Montana. 



Becoming smaller in northern regions and growing 

 close together, festooned with long, black, funereal tree- 

 moss, certain trees, that are only found on alpine heights 

 of southern latitudes, are content to strike root with 

 others in the sphagnum swamps of Alaska, only a few 

 feet above sea-level, but in a climate similar in severity 

 to thatof their normal alpine homes. Only half a dozen 

 conifer trees, all greatly dwarfed, and one prostrate shrub, 

 can outlast the rigors of Alaska winters the Coast Scrub- 

 Pine, the Tide-land Spruce, Pacific Red Cedar, the 

 Western Hemlock, and the elsewhere alpine trees, the 

 Hooker form of the Alpine Hemlock, and a creeping 

 Juniper reach the northern border of the great North- 

 west forest.
