aërodrome.
_Monday_, February 1: Went out twenty minutes
on Blériot "roller."

The Blériot "roller," called the Penguin because of its abbreviated
wings, and which did not leave the ground, was followed on Wednesday,
February 17, by a three-cylinder 25 H.P. Blériot, which rose only thirty
or forty meters. These were the first ascensions before launching into
space. Then came a six-cylinder Blériot, and ascensions became more
numerous. Finally, on Wednesday, March 10, the journal records two
flights of twenty minutes each on a Blériot six-cylinder 50 H.P., one at
a height of 600 meters, the other at 800, with tacking and volplaning
descents. This time the child sailed into the sky. Guynemer's first
flight, then, was on March 10, 1915.

This journal, with its fifty pages, ends on July 28, 1916, with the
following statement:

_Friday_, July 28.--Round at the front. Attacked a group of four
enemy airplanes and forced down one of them. Attacked a second
group of four airplanes, which immediately dispersed. Chased one of
the airplanes and fired about 250 cartridges: the Boche dived, and
seemed to be hit. When I shot the last cartridges from the Vickers,
one blade of the screw was perforated with bullet-holes, the
dislocated motor struck the machine violently and seriously injured
it. Volplaned down to the aërodrome of Chipilly without accident.

A marginal note states that the aëroplane which "seemed to be hit" was
brought down, and that the English staff confirmed its fall. This
