latestmagicbeing00hoff.pdf | 179 | - - eighths of an inch thick and covered as to its upper side with fine black cloth. To the cloth-covered side of this is attached, by means of a screw at each corner, a parallelogram of brass or copper wire enclosing a space two inches wide. The four screws, which are likewise of brass, and which are Fig. 35 of the round-headed kind, are within the parallelo- gram and serve to keep the wire extended. Mid- way at each end is another screw, driven in out- side the wire, in such manner as to make all taut. These last two screws, for a reason connected with the working of the trick, stand up a shade higher than the other four, but the difference is not great enough to be noticeable. See Fig. 35. |
