Up-stream journeys were made by dragging the canoes with ropes, called ' tracking,' by which from two to ten miles a day could be accomplished, depending on the swiftness of the current and the character of the banks. If conditions were favorable, recourse was had to poling, by which much better time can be made. When the head of canoe navigation was reached, explorations into another watershed were made and a portage route determined upon. Then, if necessary, a trail was chopped and bridges built. Finally, the whole outfit was carried over by the members of the party. The longest portage made by a survey party was eighteen miles; but the work of transporting half a ton of supplies for such a distance is almost heart-breaking.
