Review of reviews and world's work . e diameter,—about 20feet,—the blades of whichare practically small aero-planes.

Aeroplanes of the first class gen-erally consist of a single plane, or pair ofwings, attached to the front end of a longbody which terminates at the rear in somekind of a tail, combined with horizontal andvertical rudders. Biplanes, triplanes, andother multiple-surface machines, in additionto a horizontal rudder in front, generallyhave a tail mounted upon sticks or bamboopoles extending back from the main planes;although the latest Voisin biplane has a bodyof square cross section similar to that of amonoplane, upon which the box tail is so.
