322 REPORT UNITED STATES ENTOMOLOGICAL COMMISSION. 
means as their own experience and this Commission have suggested in 
the first and present reports; for the State and Territorial and county 
governments to make and execute laws for combined and persistent 
action during times of general local invasion and for the prevention of 
others. If this be done in the plateau region in the future the invasions 
of the western border Mississippi States will tend to become more and 
more feeble, inconsiderable, and harmless, until, we venture to predict, 
the time will come when the losses from locusts will be only local and 
comparable with those inflicted by locusts and grasshoppers in the east- 
ern Atlantic States. At any rate, the western locust has already ceased 
to be a bugbear and object of dread; familiarity with its habits and 
history has already taught the pioneer farmers of Utah, Montana, and 
Colorado that with energy its ravages can be lessened if not entirely 
overcome, and no one intending to migrate west from the Atlantic 
States or from Europe need to be deterred by the fear of such alarming 
invasions as have occurred in former years."
