Locusts, usually called grasshoppers, were major U. S. crop damagers at several times in the late 19th century, in several places.
Bounties were paid at times for dead grasshopper eggs at one rate, and dead grasshoppers at another rate.
Here, a bounty of $1 per bushel was paid for 5 bushels of dead grasshoppers.
