Association at Los Angeles, August 16 to 21, and selected the 
northern route in order to see a part of North America which I 
had never visited. I desired also to join Chief Kebler, of the 
Drug Laboratory of the United States Department of Agricul- 
ture’s Bureau of Chemistry, in inspecting the drug supplies of the 
Pacific coast; to study and collect our indigenous drugs in the 
interest of the same department, and to collect economic material 
for our own museum. In connection with the above work, I 
prepared to make such general botanical collections in the regions 
visited as my remaining time permitte 
My first stop, July 23-26, was ede at Lake Ida, near Alexan- 
dria, Minn., where I visited Dean Wulling, of the School of Phar- 
macy of the University of Minnesota, for the purpose of discuss- 
ing important matters relating to our system of pharmaceutical 
education. t this point I found an abundance of Zanthoxylum 
americanum, the northern prickly-ash, and collected specimens 
of its bark and fruiting branches. I found here also Braunenia 
angustifolia, the root of which is now attracting considerable atten- 
tion asa drug. An interesting form of Apocynum hypericifolium 
grows upon the shores of this lake, which is apparently identica 
with one growing upon shores of lakes in southeastern New Yo 
The most important object of search, at this point, was Polygala 
Senega, which I greatly desired to study in the field. To my 
surprise, I was unable to find this species anywhere in that vicin- 
ity, though it is abundant in both the southern and northern 
parts of the state. Neither the locality nor the season was pro- 
lific of collection-material, but I obtained a number of miscella- 
neous species. 
My next stop was at Glacier, British Columbia, in the Selkirk 
Mts., July 28 and 29. w species were collected at interven- 
ing stations, en route to this point. At Glacier, the conditions 
for collecting were very favorable, and the afternoon of July 28 was 
spent in this wor I obtained about seventy-five species, their 
general character being subalpine, as the glacier extends down to 
within a few hundred feet of the locality. I desired to collect 
at a higher altitude on the following day, but felt it more impor- 
tant to spend my entire time in collecting the rhizomes and roots
