| Of March 10. IN an editorial on Flying" you
suggest that Mr.. Jilienthsl should come over
70 New York and show us how TO nv. Several
people have written 20 me for information re.
eardIns the price OF q Liienthsl apparatus,
presumably with the Intention OF buying one
to taste the delights Of flying.
This IL evidence Of an interest In ths subject
but IL IL an interest which cannot be satisfsc-
tory TO the American inventor because II
wholly lacks what might be called the Hall

course. IN see Mr.. Lilienthal soar through the
afr with hi. apparatus; but IL would be as In
teresting and more gratifying to see an ex-
hibition Of an American Improvement on the
LilIenthsl device.

Lancaster is said never to have been able to
repeat these experiment successfully at the
North but this is not conclusive evidence that
he did not send OF hundreds Of them while
perched In the tops OF dead pine trees on the
ow coast OF Florida. rs he says he did. The
l.iienthal apparatus operates precisely as did
,ho Lancaster effiRies years aeo-it Is carried
iirectly or approximately against the wind.
And whom french publications-the Repus
Dnirerseue. for instance-admit that Mr.. Lil.
enthsl really accomplished sailing flight as
'tated By him. ono must be sinRulAriy obtuso
low to doubt that our Mr.: Lancaster caused
prototypes Of the Lilienthal device to ny as the
afe vehicle only when guided By an expert.

marks the beginning OF q new era-an
