BROAD-LEAVED MAPLE.

 Washington territory and Oregon, and along the California Coast ranges and western slopes of the Sierra Nevada 

 to the San Bernardino mountains and Hot Spring valley, San Diego county (Parish Brothers), not ascending above 

 4,000 feet altitude. 



A tree 24 to 30 meters in height, with a trunk 1.20 to 1.50 meter in diameter; along streams and river bottoms, 

 reaching its greatest development on the rich bottom lauds of the Coquille and other rivers of southern Oregon, 

 where, with the California laurel, it forms dense, heavy forests. 



Wood light, soft, not strong, close-grained, compact, easily worked, susceptible of a good polish; medullary 

 rays numerous, thin; color, rich light brown tinged with red, the sap-wood lighter, often nearly white; specific 

 gravity, 0.4909 ; ash, 0.54; largely used in Oregon in the manufacture of furniture, for ax and broom handles, 

 frames of snow-shoes, etc. ; specimens with the grain beautifully curled and contorted are common and valued in 

 cabinet-making.
