The blade approaching the water will be sub-merged edgewise with a minimum of resistance. Whenfully immersed, the pressure of the paddle-blade and theimmobility of the water when subjected to sudden im-pact, will rock the blade back until it impinges uponthe arms immediately behind. The successive rear-ward movement of the blades will cause them to en-gage the water throughout their areas, when sub-merged, so that they will exert a maximum paddle-blade, by reason of its rearward inclina-tion, will leave the water edgewise. Thus the paddle-blades are feathered while entering and leaving thewater, and thus the tendency of ordinary wheels tolift a mas
