Forest trees of North America. 1 



This brochure of plates will come as a surprise to almost every 

 botanist. Very few, even of Dr. Gray's friends, were aware of the 

 existence of these plates or of the projected work which they were 

 intended to illustrate. They were stored at his house and after his 

 death were sent to the Smithsonian Institution whose property they 

 were. The 300 copies are now " distributed to the principal botanists 

 and museums of the world as mementos of the distinguished man who 

 gave so much of his life and labors to this department of knowledge." 

 The few plates now published (from Mr. Isaac Sprague's admirable 

 drawing) make us wish that the expensiveness of the undertaking and 

 Dr. Gray's preoccupation had not prevented the preparation of text 

 and the completion of the work. We may well congratulate ourselves, 

 however, that the Secretary of the Smithsonian Institution has author- 

 ized the distribution of them, even in their incompleteness. 



Botanist's Directory, 



The useful Correspondance Botanique of . Morren having become 

 antiquated Wilhelm Engelmann of Leipzig, the well-known publisher, 

 has issued a list of living botanists, of botanical institutes, societies 

 and periodicals*. 



The compilers are hidden behind the term " Fachmanner." Of 

 course one looks first at the addresses of his own countrymen. For 

 the United States we find many of them sadly awry, and it is a pity 

 that the MS. or the proof was not submitted to some American 

 " Fachmann." We could name a dozen who could have corrected 

 three-fourths of the errors and have added many names worthy of in- 

 sertion. However, the main value of the book to Americans lies not 

 so much in the accuracy of the American addresses as in those of 

 foreigners. We may well believe that for the continent of Europe at 

 least the work much surpasses in fullness and accuracy the United 

 States section. It is sure to prove of great use to all who have an? 

 European correspondence or who wish to be able to distribute papers 

 or specimens wisely. The addresses are grouped by cities, and an in- 

 dex of persons and one of places at the end enables one to find any 

 address of which he has even an inkling. The publisher will be grate- # 

 ful for notice of corrections. We hope that American botanists will 

 see to it that their ad dresses are correctly given in future editions.
