We are well acquainted with Mr. Gardiner’s specimens, 
and can confidently recommend them as beautifully preserved 
and correctly named. Indeed it is wonderful how, at the 
low price he has fixed upon his plants, he can possibly make 
the preparation of them answer his purpose: but the explana- 
tion is perhaps found in his own words in a letter lately 
addressed to the writer of this notice. ‘‘ Should the specimens 
be such as to merit your approval, your recommendation of 
them would be of great service to me in procuring sub- 
scribers for next season's collections; for it is still my inten- 
tion to devote a portion of one or two seasons more to this 
employment. By these means I trust I may be instrumental 
in extending and cherishing a taste for our favourite science ; 
and such a result would be the most gratifying reward for 
my humble labours.” 
Those who are disposed to encourage so deserving a

Botanical Collections of North-West America. 
We take much’ pleasure in announcing that three enter- 
prizing Botanists are engaged in exploring the most interesting 
portions of the Far West, and that their collections of dried 
plants will be offered to subscribers, in sets, as they come to 
hand. Two of these collectors, Mr. Charles A. Geyer, well- 
known as formerly the botanist of Mr. Nicollet's official north- 
Western expedition, and Mr. Lüders, who are for the present 
attached to Sir Wm. Stewart's party, have by this time reach- 
ed the Rocky Mountains. The particular field of Mr. Geyer's 
9perations, and the extent of his journey, were undecided at 
the time of his departure from St. Louis. Mr. Lüders expects 
to spend next winter, and perhaps the ensuing summer, 
at a station of some Roman Catholic missionaries on the - 
Upper waters of Lewis and Clarke's, or Great Snake River. 
These botanists, being well acquainted with the vegetation: 
of the general Valley of the Mississippi and of the lower 
Missouri, will doubtless avoid the common and better known
