Of creative powers Technical men who
are far enough from the work to see

have a special opportunity for useful

| Under tho heading "Aeroplane Motive
Power Improvement the appeal sets
forth the situation in regard to the
quantity production of nghtng planes

| THE present situation with respect
to the Improvement Of airplane motive
power Is that the Government is con-
centrating all It's energies upon the quick
production OF the best design 1t has
been able to select from present motor
| development For manufacturing rea-
sons II was obviously necessary to
standardize this design Nand Just now
the Government Is not N a position TO
consider improved motors ana systems
OF power. Such questions must be de-
| ferred II possible until after the press
Ing needs OF the moment nave been met

| AT all times, however, advances
| which are great enough and which have
been srifficiently proved necessarily com
ma nd a right Of way Power develop
ment Is moving 50 swiftly and there is
| 50 much room for its advance that
nothing is really fixed and no nation Il
taking q chance OF overlooking anything
which Is really worth while. Minor
improvements applicable with the pres
ert motor can be considered at any time
