OAK FAMILY. 



317 



saucer-like sessile cup, of which the scales are so compact as to present a smooth or 

 nearly even surface.

Obs. Justice to myself, and to the truths of Natural History as well 

 as to Mr. RMERSON, author of the admirable Report on the Forest Trees 

 and Shrubs of Massachusetts, requires that I should here rectify a 

 misapprehension under which 1 labored when I compiled the first edition 

 of this work. I had always understood (of course from others having 

 no personal knowledge of the subject,) that the bark of this species was 

 in high repute with the Tanners, and so stated. But on a more careful 

 and particular inquiry of intelligent and practical men, in that business, 

 I learn that it is regarded as being much inferior in value to the bark 

 of Q, cocci'nea, and am now satisfied that Mr. EMERSON is substan- 

 tially correct in the statement that it is " almost worthless for the use 

 of the Tanner." The timber of- this tree is also of inferior value.
