 Your favor of June date is on hand and for it I beg
 leave to Express myself much honor'd.


 The present position from which I hail is by no means as good as
 one for herborizing as Dr Webster from the vicinity of wh all
 the plants forwarded have been procured. Still I think of the
 very few yet observed here I have perhaps several species of
 interest. The finest and perhaps rarest plants found about
 the Sierra Del Cobre infloresce in August, a few upon dry
 soil are to be procured principally in April and May.


 The August plants are mostly found in the Mountain Canons
 by the side of hills, and when in full flower are frequented
 by such immense numbers of the humming bird (T. Anna)
 that their perpetual buzzing resembles the noise made by a 
 Swarm of bees. These are the only localities where this tiny
 bird is to be found in this territory. But to Plants
 There is no plant in my collection of whose time of 
 influence Color of petals or sepals and habitat is not recognized
 by me at sight for that reason I did not append
 those important particulars. I have passed so much of my
 time among the bears and foxes that every plant tho
 unfamiliar by name is yet so by sight. I had expected to
 carry in my own plants, till Capt Pope applied to me.
