Rivers can haul goods and people much more efficiently and inexpensively than overland routes.
Oh. So instead of carrying weights onto their backs, the boats helped carry all that off? That's all what the rivers did?
Rivers provided water -- but for long journeys, rivers were the preferred means of transportation.
Okay. so they were the fastest and easiest way to bring merchandises. And people used the river as sources of water.
Right.
Did the rivers provide anything else?
