THE PARIS AERO SALON. Bertin.
M. Bertin's machine is a monoplane which follows in its general design conventional practice. Its main body, pentagonal in section, is a girder of wood and steel wire. In front is mounted an 8-cyl. 100-h.p. engine of M. Bertin's own design and constiuction. The tail has fixed vertical and horizontal surfaces, to which are hinged respectively the rudder and the elevators. Its chassis built up entirely of steel tubing, and although not highly original, is, nevertheless, extremely neat and effective. Its flexibility is derived from steel compression springs enclosed in the outer oblique chassis struts, the vertical centre ones acting purely as guides.
