Aside from sundry bullet perforations and certain unimportant scars in the wings, it was all right. The tank was pretty full yet, the interior mechanism in fair order, and the wheels propelling it in such good shape that Blaine soon had it back in the open space where he had been compelled to come down. As for the near-by woods, there was not much real life there.
It usually amounts to a couple of hours; sometimes it exceeds half the day. With what object are these perforations made, so laborious and yet so often unused? Let us first of all discover the position of the egg, and the first mouthfuls taken by the grub, and perhaps the reply will be found.
The little pictures on the film are still today exactly the same size as those which Edison used for his kinetoscope and the long strips of film are still gauged by four round perforations at the side of each to catch the sprockets which guide the film.
Lay the tracing upon some substance of the nature of thick felt, then with a pricker or a needle, held in an upright position, pierce tiny holes all round the outline of the pattern, very close together. This completed, attach the perforated tracing securely to the material, the smooth side of the perforations towards the stuff.
Lumberers have a notion that he is harmful to timber, digging little holes through the bark to encourage the settlement of insects. The regular rings of such perforations which one may see in almost any apple-orchard seem to give some probability to this theory.
The writing is thus traced by means of a series of minute perforations in the sheet, from which, as a stencil, hundreds of copies can be made. Such stencils can be prepared on typewriters. Edison elaborated this principle in two other forms one pneumatic and one electric the latter being in essence a reciprocating motor.
Then, while all save those who were at work on the dam or helping at the cannon worked at ditches to carry off the unlighted oil, Ralph made ready for another volley. Two perforations were made in the small tank, and two more in the large one, which admitted of such a discharge of the contents, that all hands could hasten to the relief of those who were working at the dams.
But many were almost perfect, and all were wonderfully deceptive and showed what could be done by a crook who had plenty of time. "But how about the perforations?" he was asked. "How could a crook change them?" "Nothing easier," was the reply. "The fact that checks stamped with the amount in perforated characters are considered safe aids the swindler.
Inside the barrel of the electric pen a little plunger, carrying the stylus, travels to and fro at a very high rate of speed, due to the attraction and repulsion of the solenoid coils of wire surrounding it; and as the hand of the writer guides it the pen thus makes its record in a series of very minute perforations in the paper.
The sermons were often two hours long, and by the time they were ended the faithful listeners well deserved the nickname of "blue-skins" which the scoffers gave to them. A few of the wealthier women carried "foot-stoves" from their homes to their pews. A "foot-stove" was simply a square tin box in a wooden frame, with perforations in the sides.
