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 for 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 McKinuey and along the eastern flanks 

 of the Big Horn Mountains, a section admirably adapted to be a breeding 

 ground for C. 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 thence 

 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 Yellowstoue, 

 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.
