reported, but not in such numbers as those mentioned above. At one 

 or two localities, viz, on Ui){)er Powder River, and at a point about 

 twenty-two miles west of Douglas, native hoppers of various kinds had 

 done some little injury to gardens, but nothing further. 



Finally, unless there should be swarms at present unknown to me in 

 Montana, Northern Dakota, and the British Possessions to the north — 

 and the swarms of Ottertail County, Minn., and neighborhood have 

 been pretty well reduced — there is no danger of an invasion for several 

 years to come.
