Continuing on my Oregon Trail historical research, I came across the "leeverites."  This term was sometimes applied to people who went along after the wagon trains and picked up a lot of the things that the pioneers left, to lighten their loads.  Since it was common to say, "Leave 'er right here," the plunder became "leeverite" and the scavengers, which people despised, were not well liked at all.   What was most dispicable was their practice of selling the cherished items back to the members of the wagon train, at various trading posts or "jumping off" places along the trail.  People who "jumped off" were those who didn't go any further, and settled somewhere like Independence.  In some letters preserved from the past, people wrote that "those  who sell leeverites don't care about anyone but themselves."
