450 REPOKr OF STATE BOARD OF HORTICULTURE. 



i^anyt^Cascade and Galton ranges to the Rocky Mountains, at elevations 

 of six thousand to seven thousand five hundred feet in Washington and 

 British Columbia, and reaching nine thousand to ten thousand feet in the 

 Bitter Root Range in Idaho. 



ENGELMANN SPRUCE. 

 (Picer Engelmann Engelni.) 



This species has a greater altitudinal range (two thousand to seven thou- 

 sand feet), and possesses proportionate powers of adaption to conditions of 

 humidity. and dryness, consequentlj' it varies greatly in size. On dry ridges 

 it occurs small, schubby and stunted, with manj' abortive and few fertile 

 cones, while in moist, rich valleys it becomes a magnificent tree one hundred 

 to one hundred and seventy-five feet in height and two and one-half to six 

 feet in diameter, bearing large quantities of fully seeded cones which are 

 massed near the top, thus assuring greater distribution and abundant propa- 

 gation. 



Jiange — Oregon to the Rocky Mountains, and north to British Columbia 

 and the Peace River region, Athabasca, latitude 55° 47^ north. 



Though not know to occur in California it has been found in Northern 

 Arizona. 



T\S( — Much used for lumber and fuel in Eastern Oregon. 



BL/UE SPRUCE. 

 (Pimgenn, Engelm.) 



A medium-sized tree noted lor its very sharp foliage, hence the specific 

 name." Not yet collected in Oregon, but reported as occurring in the south- 

 eastern part of the state. 



.i?aH(/c— Rocky Mountains westward to Wyoming. 



TIDELAND SPRUCE. 

 (P. Sitehensis (Bong.) T. &;M.) 



One' of the moisture-loving coast trees seldom found at any great distance 

 inland and reaching the extreme limit of its altitudinal range at about three 

 thousand two hundred feet. Though little, if any, taller than the Engelmann 

 spruce, it grows to a much larger size, specimens of fifteen feet or more in 

 diameter being' sometimes found. When grown in the open it is pyramidal 

 in shape, abundantly and symetrically branched, and makes a beautiful lawn 

 tree. In the forest it is slower growing, closer grained, free from limbs for 

 fully two-thirds of its height, and being fairly free from pitch it makes clean, 

 serviceable lumber. It is the tree almost exclusively used for lumber and 

 fuel in Southern Alaska. The bark is thicker than that of the Engelmann 

 spruce. The cones, which are two to four inches long, are not so much 

 massed at the top of the tree and probably not quite so abundant, but it 

 nevertheless appears to propagate readily and hold its own except where 

 removed for agricultural purposes or destroyed by forest fires. 



Bange — Northern California to Cook's Inlet, Alaska. In Oregon, Clatsop 

 County contains the finest forests of this tree at present. 



Use — Lumber, fuel, paper pulp, piling, barrels, boxes, shooks, excelsior, 

 and boat building.
