After various minor flights in the spring and summer of 1908, Blériot,
on October 31st of that eventful year in aviation, determined to
attempt a cross country voyage, as Farman had done the day before. As
will be remembered, Farman had flown from Chalons to Rheims, above
trees and houses, a distance of nearly 17 miles, thus achieving the
first town-to-town flight in history. Blériot would improve that record
at once, by flying in a closed circuit embracing several villages.
His renowned cross-country flight was directed from Toury to Artenay, a
village nine miles distant. Mounting his aëroplane _VIII-ter_, at mid
afternoon, in presence of a large gathering, Blériot followed the
course shown in Fig. 40. In the neighborhood of Artenay he landed for a
few minutes. After some slight repairs to his magneto, he reascended,
turned about and headed for home. Half way on his return course he
stopped again for a few minutes, at the Village of Santilly; then
readily reascended and flew to the neighborhood of his starting point.
He thus traveled about 17 miles in a closed circuit. This performance,
with that of Farman the day before, inaugurated the period of aërial
voyages in heavier-than-air machines. It appealed so powerfully to the
sentiment of the community that a monument was erected at Toury to
commemorate the glorious achievement.

A fair view of the famous monoplane, in its renowned cross-country
voyage, is presented in Plate XXV. It consisted of a single sustaining
surface firmly attached to a long trussed spine mounted on three
wheels, and carrying at its front end the gasoline motor and propeller,
at its rear end two of the rudders, the third, or lateral, rudder
being placed at the wing terminals. A part of the trussed frame was
covered, to minimize the atmospheric resistance against the framing,
pilot and engine. The vertical rudder at the rear turned the machine
to right or left; the horizontal rear rudder controlled the elevation
and pitching of the machine; the torsional wing tips controlled the
lateral stability, and could be used to cant the aëroplane or check its
listing, as in the Wright and Curtiss machines. The craft exhibited an
easy poise in the air, and possessed good equilibrium, owing to its
arrowlike structure and its three-rudder system of control. It was a
strong rival of the biplanes previously noticed, and a herald of better
things to come.
