782 FINAL JOURNEYS AND WORK. [1886, 



America, that we know of. But having done some 

 while ago the Gamopetalae of Pringle's interesting 

 North Mexican collection, I am now switched off to 

 the same in a hurried collection made by Dr. Palmer, 

 in an unvisited part of Chihuahua, in which very much 

 is new. One after another those Mocino l and Sesse 

 plants turn up. Also those of Wislizenus, whom the 

 Mexicans for a time interned on the flanks of the 

 Sierra Madre. 



We are bound to know the botany of the parts of 

 Mexico on our frontier, and so must even do the work. 

 Pringle goes back there directly, with increased facili- 

 ties, and will give special attention to the points of 

 territory which I regard as most hopeful. 



Trelease, 2 our most hopeful young botanist, es- 

 tablished at St. Louis, - - is here for a part of the win- 

 ter, to edit a collection of the scattered botanical pub- 

 lications of Engelmann which Shaw pays for - - or at 

 least pays for to a large extent. He would have the 

 plates and figures, and that will double the cost and 

 the sum Shaw offered to provide. We may have to 

 sell some of the edition in order to recoup the 

 charges. . . . 



Yes, you hit a blot. I can see to all my own books, 

 such as the "Synoptical Flora." But, somehow, I 

 cannot restrain the publishers from altering the date 

 of their title-pages when they print off a new issue 

 from the stereotype plates. . . . 



1 Josef Mariano Mocino. Was on the coast of California in 1792. 

 Botanized in Mexico, especially in the northern part. His drawing's, 

 brought to Europe after the death of Sesse*, were left with Aug. Pyr. 

 de Candolle. When suddenly reclaimed they were copied for him 

 by the united labors of the ladies of Geneva. 



2 William Trelease, St. Louis ; professor of botany at Washing- 

 ton University, and director of Missouri Botanical Garden.
