This having been accomplished, Mr. Seymour proceeded to form the
framework of the kite in the following manner. He first ascertained the
central point of the bow, by balancing it on his fore-finger; he then
affixed that point, by means of string, to the lath, at _c_, about an
inch and a half from its upper extremity; a notch was next cut in each
end of the hoop, or bow, _a d_; having fixed the string in the notch,
_a_, he drew it through another, _e_, previously cut in the bottom of
the lath, and carried it to the opposite end of the bow _d_; the
skeleton now presented the usual form, of the kite. The next point,
therefore, was to ascertain whether the two sides of the bow were in
equilibrio, which he determined by balancing the lath on the finger,
and observing whether it remained horizontal, or dipped on either side.
This adjustment having been accomplished, Mr. Seymour next continued
the string from _d_ across the skeleton to the opposite notch _a_,
giving it one turn round the lath in its way; from _a_ it was carried
to _f_, and wound round the top of the lath, and then again fastened at
_d_; from _d_ it was extended rather more than midway down the lath,
and having been secured at _b_, was finally carried to, and secured in
the notch _a_. The framework was now pronounced by Mr. Seymour to be
complete.[41]
The next part of the process was to cover it with paper. Mr. Seymour
observed, that the best kind which could be employed for this purpose
was that known amongst stationers by the name of _fan paper_, so called
from its being manufactured for the use of the fanmaker; its merits, he
said, depended upon the size of its sheets, as well as upon the
thinness and firmness of its texture: this, however was not at hand; he
was therefore obliged to rest satisfied with its best substitute, viz.
folio sheets of large thin post.
The party now went “ding-dong” to work; paper, paste, and scissors were
immediately put in requisition. Sheets of paper were laid smooth on the
table, and so arranged that each sheet overlapped its neighbour about
half an inch. The skeleton of the kite was then placed upon them, and
the paper was cut to its figure; a margin, of about three-quarters of
an inch, having been left around it, except over the bow, where the
margin was extended to an inch in width: this arrangement was for the
purpose of allowing the paper to turn over the framework, when pasted
to it. This part of the work having been completed, and a sufficient
time allowed for the drying of the paste, Mr. Seymour proceeded to fix
the string, usually termed the _belly-band_: for this purpose two holes
were drilled through the lath, at equal distances from its edges; the
upper one about a fifth part of the length of the kite from the top,
the lower hole rather more than the same distance above its extremity.
