Henning's first report from France.

Hotel D'Angleterre
BOURGES.

Monday August 18, 1924.

We started from Paris this morning in a S.W. gale with frequent heavy showers, real drenchers.

We were going S.E. so got it on the starboard quarter. We got on a road as smooth as a billiard table but not so level, in fact a very pronounced camber on it.

The conditions were perfect for producing skidding on applying the brake (foot) sharply at 45 m.p.h. The rear would skid and would develop a bad one if not corrected but there was not a suspicion of a front skid.

We struck a bad road suddenly at 67 m.p.h. and one had to do some steering but no great power required but more than with, say, 14-PK.

I did not have to alter carburation as it is just right for the French Petrol, but it certainly was too rich for English Aviation spirit.

I had to open starter carburetter jet 90 degrees before it would start on the petrol supplied by R.R. Paris

Thermostat nut loose this morning and leaking water on cylinders; tightened up O.K.

Steady pin of the off side rear foot-brake squeaks.

We did 198 miles.

Car behaving very well.

J.H. Henning.
