with Abies Sub. Alpina, Pinus Flexilis, and Pinus Aristata in its 

 upper altitudes, and with Pinus Ponderosa and Pinus Contorta in its 

 lower altitudes. 



This spruce is doing remarkably well wherever tried ; it trans- 

 plants as well as the Menziesii, and makes a very handsome pyramidal 

 tree. The foliage varies in color from a dark green to a very light 

 bluish-green. It is a very slow grower, but is beautiful at all times r 

 and should be in every collection. 



Picea Alba Dakotaii, Black Hills Spruce. This spruce is a variety 

 of the White Spruce which is destitute of the unpleasant odor of the 

 eastern variety. It is found in Wyoming, Dakota, and in the moun- 

 tains north and west from there, up into the British Possessions. It 

 is a rapid grower, and makes a very beautiful pyramidal tree. It 

 transplants easily, and should be in every collection. 



Tsuga Douglasii (Lindley) ; Abies Douglasii (Carriere). This beau- 

 tiful conifer was discovered by Menzies in the year 1797, at Nootka 

 Sound. The variety we have in Colorado is perfectly hardy, while 

 the variety found on the Pacific coast is tender. This is the nearest 

 approach to the hemlock of any variety in the mountains in Colorado. 

 It is distributed over a greater range of altitude than any other con- 

 ifer, except the Pinus Ponderosa, which occupies the same region as 

 the Douglas, but extends to much lower altitudes. The Douglas is a 

 little hard to transplant. It should be in every collection. 



Pinus Ponderosa Douglas. — This pine is found growing every- 

 where in the Pocky mountains from Southern Colorado to Northern 

 Dakota, and probably further north. Its altitude is from 4,000 to 

 10,000 feet. It is found most plentiful at 7,000 to 8,000. Is found 

 north of Empire, Colorado, at an altitude of a little more than 10,- 

 000 feet, also on Pike's Peak to about 11,000. It grows in North- 

 western Nebraska, on the Niobrara and Loup rivers, at an altitude 

 of about 4,000 feet, and is the only pine indigenous to the state of 

 Nebraska.
