capture by hand a hundred or more ka-cho' during half a day, simply
by following them in the shallow water.

The ka-cho' is also caught in great numbers by the second or driving
method. Twenty to forty or more men fish together with a large,
closely woven, shovel-like trap called ko-yug', and the operation is
most interesting to witness. At the river beach the fishermen remove
all clothing, and stretch out on their faces in the warm, sun-heated
sand. Three men carry the trap to the middle of the swift stream, and
one holds it from floating away below him by grasping the side poles
which project at the upper end for that purpose. The two other men,
below the trap at its mouth, put large stones on their backs between
the shoulder blades, so they will not float downstream, and disappear
beneath the water. As quickly as possible, coming up a dozen times to
breathe during the process, they clear away the rocks below the trap,
piling them in it over its floor, until it finally sinks and remains
stationary on the cleared spot of sandy bed. Their task being ended,
the three trap setters come to shore, and sprawl on the hot sands to
warm their dripping skins, while the sun dries and toasts their backs.

Then the drivers or beaters enter the river and stretch in a line from
shore to shore about 75 feet below the trap. Each fellow squats in
the water and places a heavy stone on his back. One of the men calls,
and the row of strange, hump-backed creatures disappears beneath
the water. There the men work swiftly, and, as later appears,
successfully. Each turns over all the bowlders within his reach
as large or larger than his two fists, and he works upstream 4 to
6 feet. They come up blowing, at first a head here and there, but
soon all are up with renewed breath, waiting the next call to beat
up the prey. This process is repeated again and again, and each
