INFORMATION FOR EMIGRANTS, 



17 



The following is a tabular view of the years in which the Rocky 

 Mountain Locust has appeared, from the earliest date known, up to 

 • and including the year 1877. * 



For want of room, I have omitted from 'the table Texas, Arkansas, f 

 Indian Territory, Missouri, New Mexico, Arizona, Nevada, Washington 

 Territory, and Oregon : , 



As may be seen by reference to the foregoing data, in most of these 

 years the actual loss to crops was more or less slight. The years in 

 which losses were sustained by the young hatching in the spring, and 

 in which there were afterwards in that season no invasions, . are starred. 

 The years in which more or less severe damage was done are in full-faced 

 type.
