 aridity of the climate and lateness of season were
 entirely dried away. A passage through this 
 region during the spring or summer months would
 be highly interesting to a botanist with proper means
 for collecting and preserving his specimens.


 If Prof. [Professor] Asa Gray has returned from Europe 
 I should be pleased to have my Phenogamous plants
 sent to him. In his absence Prof. [Professor] Torrey of N.Y. [New York]
 or Dr. Engelman [Engelmann] of St. Louis would be excellent hands 
 to leave them in if they would take their examination
 and reduction to task immediately. My Filicoids 
 and mosses are small in point of numbers and 
 probably also of interest. I should be glad to have
 them sent to my friend W.S. Sullivant Eqr. [Esquire] of
 Columbus Ohio. A synoptical catalogue and
 a short diagnostic description of such as are
 new species it would be well to have furnished
 for publication in Sillimans American Journal 
 of Science as soon as possible. The advantage
 of this measure will be that we can thus secure
 the priority and honor of what new discoveries 
 we make that might otherwise be lost by delay
 being anticipated by after explorers-the credit
