An account of a fire during a bison hunt comes from the translated journal of a Jesuit priest in 1680:
When they see a herd, the Indians assemble in great numbers. They set fire to the grass all around these animals except for one passage left on purpose. There the Indians station themselves with their bows and arrows. The buffaloes, wanting to avoid the fire, are thus forced to pass by the Indians, who at times kill as many as a hundred and twenty of them in one day. The buffaloes are distributed according to the needs of the families.

I do believe that method would work well to round up illegals who have crossed the border. Yessir, good idea!.
