was visited by a snow-storm. From this locality I forwarded to the 
Department a sample of plant that is said to kill stock, and is known in 
this section as the “loco” weed.* From Fort Garland we returned north- 
ward via Denver and Rio Grande Railway to Denver, and thence to Fort 
Collins, where we were detained until July 1 on account of the scarcity 
of funds. While there, we occupied the time in collecting and examin- 
ing wheat fields tor insects, as well as in studying the preparatory stages 
of different locusts. From Fort Collins we proceeded by wagon to the 
North Park, where we expected to obtain some data and material in 
special directions, but upon our arrival in the park we found we were 
too late to procure what we were after. We therefore, after learning 
that the streams were still too much swollen to reach the higher eleva- 
tions, proceeded to Laramie City, Wyo. After a few days’ detention at 
this point we left for Rock Creek Station, on the Union Pacific Railway, 
from which latter point we proceeded by stage to Junction City, Mont., 
the route by which we traveled taking us across the well-grassed plains 
between Forts Fetterman and McKinney and along the eastern flanks 
of the Big Horn Mountains, a section admirably adapted to be a breeding 
ground for (. spretus. On this trip we laid over a few days at Fort 
McKinney and part of a day at Custer’s battle-field, to collect. 
From Junction City, with your permission, we deviated from the 
original plan and proceeded westward instead of following down the 
valley of the Yellowstone to its junction with the Missouri and thenee 
across the plains lying to the northward between this river and the 
Souris. We first went to Bozeman, where we procured horses, after 
which we rode across the country via the valleys of the Yellowstone, 
Upper Madison, and Snake Rivers into that of the Salmon River. On 
this trip we also collected at various points along the route, besides 
making numerous inquiries relative to the migratory locusts. Upon our 
arrival at Salmon City, Idaho, we found that our time which had been 
allotted for field work had almost expired. After a few days had been 
spent upon the object of our trip, we returned to the railroad, where we 
took the train for Ogden. Arriving at Ogden, we found that we still 
had some time at our disposal; we therefore devoted it to collecting and 
in visiting the orchards of several of the principal horticulturists, both 
in the vicinity of Ogden and Salt Lake City. From Ogden we returned 
to Washington via West Point. 
I am pleased to be able to report that the leading feature of our notes 
for the summer’s work is the comparative freedom from all insect plagues 
throughout the entire area traversed by us. 
The report you will observe is chiefly in the form of notes as they 
were taken down from time to time while in the field. 
I am, respectfully, yours, 
LAWRENCE BRUNER.
