Testimony as to Conditions. 
The following letter, taken from a large number of similar com- 
munications, received in 1910, is fairly indicative of conditions in 
the Western and Northwestern part of our state. 
“Everdell, Minn., June 25, 1910 
Mr. F. L. Washburn, 
State Entomologist, 
St. Anthony Park, St. Paul, Minn. 
Dear Sir: Received your order dated June 18th, for 25 gallons of kero- 
sene, and wish to thank you for the same. At the same time I want to call 
your attention to the fact that the farms I am working have a total of about 
twelve hundred acres in crop this year, and very likely there will be con- 
siderable more needed than the 25 gallons, Will you not furnish more? 
The grasshoppers seem to be very numerous, and already it is claimed 
that they have done and are doing damage. A number of farmers are trying 
to work against them with the hopperdozers, but the trouble is that there is 
so much land not being cultivated, growing grass; and it seems that they 
are very numerous on such land, and the trouble is that they breed on such 
Jand and afterwards go to the grain on the cultivated land. 
The situation here is fierce. ‘This will be the third successive year that 
the grasshoppers have been doing damage on a large scale, and if there is 
anything that you can do through the state to help the farmers in this 
locality, it ought to be done. 
Thanking you in advance for a prompt reply, I am, 
Respectfully yours,” 
These Grasshoppers Are Not the Rocky Mountain Locust or 
Grasshopper. 
Reference has been made above to the fact that the grasshop- 
pers doing the damage in 1909 and 1910 are not the Rocky Moun- 
tain variety; and it was further stated that for some reason the lat- 
ter form (M. spretus) has not been apparent in its usual haunts for 
many years. In this connection I quote from two letters recently 
received. One from the State Entomologist of Montana reads as 
follows : 
“T have been collecting Orthoptera in Montana for thirteen seasons now, 
and have in the collections about 170 species, of which about a dozen are new 
and undescribed. I have looked particularly for M. spretus (Rocky Mountain 
Locust), but have not taken a single specimen, nor have I taken one that 
approached this species. This has been particularly interesting to me, in
