EDIT TAL. 
The year 1900 has seen the addition 
of 140 pages to the volumes of the West 
American Scientist-far less than we had 
hoped but not a bad showing in the face 
of the difficulties we have met with. 
It is our purpose to bring together in 
these paves descrip.ions of all the ani- 
mals, plants, ae Is, etc. of the west, 
together with no of economic a 
geographic soatheshce bibliography, 
synonymy, etc 
3 
Qu. 
The cooperation of our readers is  in- 
vited, and our services in turn we offer 
in determining names of minerals, shells 
and plants, or in any way that may tend 
to increase interest in these branches.
