“Undoubtedly,” replied Mr. Seymour, “and for obvious reasons; the
curvature of the bow enables it to escape the resistance of the air, as
it rises; which, after having struck it, slides off, just as the
current is more effectually turned aside by the gently curved prow,
than by that which has a sharp outline; for the same reason, the mast
of a ship, though it has a conical shape, is more easily drawn through
the water with its broad, than with its narrow end, foremost; for
although the primary obstruction is, no doubt, greater in the former
case, yet the water heaped, as it were, on the front, is made to stream
off with a slight divergency, and therefore does not hang on the sides
of the mast, as it would in the latter case. This shape of the kite,
moreover, presents the largest surface at the point upon which the wind
can act with the greatest effect, while the whole is lightened by the
removal of parts that would obstruct its action. The tail has also a
greater control over a figure of such a description.”
Mr. Seymour asked the vicar, “whether he could explain the origin of
the French term for the kite, viz. _cerf volant_, or flying stag; I
never can believe,” continued he, “that the kite could ever have been
constructed in the shape of that animal.”
“I am unable to clear up the difficulty,” replied the vicar; “and yet I
have taken some pains upon the subject. The earliest notice of the
kite, which I have been able to discover, is in a short English and
French Dictionary, by Miege, which was published in the year 1690, and
it is there described under the name of _cerf volant_.”
“I wonder,” cried Tom, “who invented the kite?”
“In, that, again,” answered Mr. Twaddleton, “I am unable to furnish you
with any satisfactory information. The pastime appears to be of very
ancient date in China, and was, probably, first imported into Europe
from that country.”
“At what period, do you suppose?”
“Strutt, who was very assiduous and correct in all his antiquarian
researches, was of opinion that its introduction into England could not
be dated farther back than a hundred and fifty years.”
The party had, by this time, reached Overton heath; the weather was
favourable; and the kite impatiently fluttered in the breeze, while Tom
was eagerly engaged in unwinding its streaming tail, and preparing the
paper machine for ascent.
“Is the string fixed to the belly-band?” asked Mr. Seymour.
“All is ready,” replied the vicar; “and I will hold it up, while Tom
runs with it against the wind. Had King Eric set his cap for us, we
could not have had a more favourable breeze.”
“There is not the least occasion to raise the kite from the ground,”
observed Mr. Seymour; “let its point rest on the grass, and place its
tail in a straight line in front of it; I warrant you it will rise, as
soon as Tom begins to run.”
Tom immediately set off, and the kite rose majestically into the air.
