The time is almost upon us when a pack-train must wind its way up a graveled highway and turn its bellmare in the pasture of a summer hotel. When that day comes, the pack-train will be dead, the diamond hitch will be merely rope, and Kit Carson and Jim Bridger will be names in a history lesson. And thenceforth the march of empire will be a matter of gasoline and four wheel brakes.
