Hooper, Dodge County, May 14, 1877. 
The first time I noticed the Rocky Mountain locust in this locality was June or 
July, 1859. They have since then, up to the year 1866, made short visits, never doing 
any damage to the crops, nor did they at any time leave any eggs behind them. 
About the middle of September of the year last mentioned they came upon us from 
the northwest in full force, and their numbers were legions ; they came, too, to stay 
until the first slight frost in October finished their earth. y existence, seemingly all 
dying in one night; not until, however, they had left us a large crop of eggs and de- 
stroyed fully one-third of the corn crop. The eggs hatched the following spring, 
numerously in April, and the young pest seemed to outnumber the old swarm, living 
for a time, as it were, to devour everything tinted green, avoiding, after all, the 
tender corn blades. But plenty of moisture and fine growing weather checked their
