destroyed. One way of aecomplisbiDg this is to gather tlie locusts in a 

 I)ile, cover the latter with straw and then set lire to it; or they may be 

 collected in gr^iu sacks <ind immersed in scalding-hot water until life 

 is extinct, alter which they may be fed to hogs or to poultry. 



One of the best nozzles that I have ever used for spraying this solu- 

 tion is the "Cyclone" nozzle, originally introduced by the Department 

 of Agriculture. It throws a very fine spray, and by its use the upi)tT 

 as well as the under surface of the leaves can be directly sprayeil — :ni 

 ol)ject that could not be attained in using the old "San Jose" uozzlf, 

 which threw a spray from its ejid instead of from one of its sides. 



REPORT 02T THE ABUNDANCE OF THE ROCKY MOUNTAIN LOCUST 



IN 1885. 



By Lawrkn'CE Buuner, Special Agent. 



Wkst Point, Nebk., August 20, 1885. 

 Siu; Herewith is Rubinitte'l n report of my recent visit to the valley of the Lower 

 YolJowbtoue River of Eastern Mouraua and the adjoining portions of Northwest Da- 

 kota, where it was reported the '"grasshopper" ur Migratory Locust (Melanoplus 

 sprctus) had appeared in injurious numbers. 



Tbe trip was taken under your direction for the purpose of ascertaining the truth- 

 fulness of these reports, and if possible to predict for the future. 



As will bo seen by tbe accouipaiiving notes, I lirst visited Glendive, Mout., from 

 which point I worked down the YelV)\vstono Valley to its junction with that of the 

 Missouri at Fort Biiford. From here, along the latter, to Bismarck, and thence across 

 country to Harold, on the Dakota Central branch of tho Chicago and Northwestern 

 Railroad. 



Very respectfully,

The first Rocky Mountain Locfists observed on this trip were seen to- 

 day (July 29) at a point tibout 80 miles east of Glendive, Mont. They 

 were quite mimerous and were observed, as the train sped by, to hop 

 away from the side of the railroad track where they appeared to have 

 congregated for the purpose of feeding upon the rank vegetation which 

 grows upon the loosened soil of the road-bed. 



Upon going out in tlie streets of Glendive, on the moruiug of tha 

 30th instant, J observed large numbers of several species of locusts 

 upon the ground and among the scant herbage. Some of these, about 

 half, were of the migratory kind and appeared in excellent health. 

 The remaining half was composed of the Lesser Locust (Mclanoplus at 

 lanis), the Ked-thighed Locust {M. fcmur-ruhnim) and other native 

 species. By making inquiries I ascertained that elsewhere they were 

 equally numerous and at some places far more numerous even than 

 they were there. 



One peculiarity which I noticed in connection with the locust vi.siia- 

 tion here this season is the presence of everj' other species of Ujcu.»t 

 known to occur in this region in equally large numbers with the de- 

 structive species (that is, as the term "destructive species" is generally 

 understood). Even species which have hitherto been considered as rare 

 at all points in the West are this year present in comparatively large 

 numbers 5 as, for example, Bobi)edon nuhilum^ MelanopJus infantiUs and 

 Mestobregma j^ulchclla (the latter an undescribed species, which is only
