Foreseeing Ihe dilliculty, if not the imiK>ssil)ility, of lia\ing 

 a book of so teclmical a character as ''Plant IJfe" l)i-(»u_i;hl out 

 un(b*r our supei'vision alone, and kiiowim:, that the authoi-i- 

 ties of the I)ei)arlnu'nt of Agriculture, through J)r. Mohr, had 

 become interested in the work, it was proposed b}' me that the 

 first publication sliould be undertaken by that Department, 

 with the understanding that an edition for the Alabama (Jeo- 

 h)gical Survey should be printed at the same time with that for 

 the Department, each edition to liave its appropriate title page 

 and hotter of transmittal. This proposition was accepted, and 

 ■we desire here to acknowledge our obligations to the Division 

 of liotany and to Mr. Coville and the others who have i-endcn-ed 

 such signal aid in bringing out the book. In view of the un- 

 timely death of the author, we realize that we have been for- 

 tunate in having this aid, without which the book would not 

 have been printed during his lifetime, and could not have re- 

 ceived his last revisions. 



It has been thought proper and desirable in this Survey (nli- 

 tion to add a short biogi-aphical sketch of Dr. Mohr, c(»ndensed 

 from the J*It(ii'iH(icciitiscJic h'iiii<lscli(iii, together with his port- 

 rait and that of another man Avhose name will ever be honor- 

 ably associated with Alabama l)otany, Judge Thomas ^linott 

 Peters,

State Geologist.
