they are now rapidly increasing and spreading themselves over the country. The Rocky Mountains seem to have been their great rallying ground; they are found there in great numbers; and as the Prince of Canino observes, they have advanced eastward to meet the white man. These new-comers remain but a short time, about six weeks in June and July, and then disappear again, taking flight for tropical America.
