Laboratory reopened for development
of aeronautics, and it seemed advisable
10 him ito make q thorough test OF
the principles involved in the con-

air man-carrying flying machine, es-
pecially the question as to the tandem
arrangement of the planes and gem
eral stability, especially longitudinal
stability" He therefore arranged
with Glenn II. Curtiss for further
experiments with the plane at Ham
mondsport.
Mr. Brewer had declared that the
HammondSport experiments were
made for CurtiSS' ends at CurtisS eX-

prevent their collapse; that the
changes made in the engine were IN

DR.. Walcott said Mr.. Wright's $ state

Langley machine now on exhibition IN
the National Museum which have
been restored are different in con-

machine is contrary to the facts.
Restoration Is Explained.
When the machine was brought
back to the institution from Ham
mondsport after the 1914 tests he
declared, the parts which had been
damaged in the first trial fights by
Mr.. Langley in 1903 were rstored by
Mr.. Reed the very man who had built
the machine in the first place under
Mr.. Langley's direction. to be as near
" as was humanity possible exactly as
Mr.. Langley had designed them.
The parts now on the machine
which are not the original parts are
only those which il was necessary to
replace through damage or deteriora-
ton That Mr.. Wright realizes that
such 'restorations' are permissible and
necessary is shown by the fact that in
the very next paragraph of his criti-
cism to those 'restorations he says,
regarding the Wright machine:
"'Our machine still possesses its
original parts, with only a few re-
Cident after its fourth fight, on De
age suffered in the Dayton flood OF
1919"
DIR. Walcott said: Langley's whole
energy was thrown to the single aim
of making a single fight and a safe
