��A reaper boat cutting aquatic growths. The blades lie near the bottom of the pond and operate automatically by motor-power
��irregularities of the stream beds. The frame which sup- ports the cutting blades is constructed of two vertical irons and may be swung from a lever pivoted in an upright.
The paddle wheel is on a frame capa- adjustment to any depth. The wheel is driven from the gas- oline motor by a gearing and chain device. Two sep- arate countershafts are used for this purpose so as to give the necessary speed reduc- tion when cutting. The cut- ting frame may be lifted out of the water when not in use. The blades fold up alongside the frame.

The cutting blades, which are modeled after the fashion of reaper blades, are operated by a motor on the boat. The boat is about twenty feet in length, flat bot- tomed and narrow at the front and rear. A paddle wheel placed in the front of the boat is driven by a gasoline engine.
The cutting bars are placed at the rear end of the boat on a vertical frame. The blades are
made in different lengths . ^- r -i u u u i*. j •

These huge willow "gran- aries" of the Poncas are gen- erally mounted on rude platforms reached by ladders to keep them dry. Each basket has a rain-shedding cover made of grass or cedar bark. The grain kept in them remains dry and in perfect condition indefinitely.
