A tree^ ^^S^^J ^^ ninety or occasionally one hundred and twenty feet in height^ with a tall slender 

 often forked trunk^ occasionally from three to four feet in diameter^ and spreading limbs which form a 

 rather narrow head of slender more or less pendulous and often contorted branches. The bark of the 

 trunk is from one half to three quarters of an inch thick, and light gray, with a firm close surface, 

 usually divided by small fissures, the surface of the low ridges separating in close loose scales; or 

 sometimes scaly, with loose thick plate-like scales five or six inches long. The branchlets are slender, 

 and marked with oblong pale lenticels, and when they first appear are slightly angled, light green, 

 nearly glabrous, often covered with yellow scurf, puberulous, tomentose, or coated with long pale hairs ; 

 during their first year they are rather hght red-brown, glabrous, or rarely puberulous or pubescent, and 

 turn dark red in their second season. The leaf-scars are comparatively small, semiorbicular to oblong, 

 obscurely lobed, and slightly emarginate at the apex. The terminal buds are usually about a quarter 

 of an inch or sometimes fully half an inch in length,^ ellipsoidal, acute or obtuse, and two or three 

 times as large as the axillary buds ; the outer scales are acute or often slightly keeled, and frequently 

 long-pointed at the apex, light orange-brown or dark reddish brown, lustrous, and covered with soft
