BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Lakes Shoshone and Lewis, which it is proposed to stock with the land-locked salmon 
and Loch Leven trout. 
“Capt. F. A. Bontelle, U. S. Army, acting superintendent of the Park, will be 
notified by telegraph of your proposed exploration, and requested to give you every 
facility for it.” 
Other engagements rendered it impossible for us to start before September 24, 
1889, a late date for such work, as the climate of the Park is subarctic, and serious 
snow-storms may be expected at any time after the middle of September. We were 
very fortunate, however, as we arrived in the Park just after a storm, and throughout 
our stay Indiau-summer weather prevailed and no time was lost on account of snow. 
The following is the itinerary of the trip :

Spangler, librarian of the Indiana University, volunteer assistant.

Glen Creeks. 
September 30. — Seined Gardiner River about the mouth of Hot Eiver.

Our trip was necessarily considerably hurried, though long enough to enable us to 
make out the leading points of the problems in question. A more complete survey of 
the Park and the surrounding region would enable us to work out in detail the distri- 
bution of the fishes found lower down the streams. The distribution 'of the Miller’s 
Thumb or Blob {Coitus bairdi punctulatns) needs special study. The distribution and 
conditions of life of the parasitic worm {Dibotlirium cordiceps Leidy), found in the trout 
of Yellowstone Lake, as well as those of the larger worm found in the sucker of Witch 
Creek, will demand a whole summer’s attention from some one familiar with the sub- 
ject. 
In all our work we had the cordial and intelligent co-operation of Capt. F. A. Bou- 
telle, acting superintendent of the Park, of Lieut. W. E. Craighill, of the U. S. Engi- 
neer Corps, and of Lieutenant Edwards, IT. S. Army. We were fortunate in securing
