Olts. Justice to myself, and to the truths of ISTatural History — as well 

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

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

 misapprehension under which I 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. Emeesox is substan- 

 tially correct in the statement that it is " almost w^orthless for the use 

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