Description, S;c. Thisoak, according to theyounger Michaux, is theloftiest oak in America ,being from 90 ft. to 100ft. high, with a trunkfrom 4 ft. to 5 ft. in dia-meter. The trunk isstraight, and is coveredwith a deeply furrowedbark of middling thick-ness, but always black,or of a very deep browncolour; whence, pro-bably, the tree derivesits common name inAmerica ; viz. the blackoak. The dark hue ofthe bark easily distin-guishes this tree from Q.rubra, Q. coccfnea, and6- ambigua, in thenorthern provinces; but,

The inner bark of Q. tinetoria, if chewed,T ®y bitter, and gives a yellow tinge to the saliva, which is not the case with,-, e ^ k °f Q- falcata. The wood is reddish, coarse-grained, and porous,6 T? 1 the re d oaks.
