Let two persons, A and B, have their hands tied together with string, so that the strings cross, as represented in the [engraving]. The object is, to free themselves from each other without untying the knot. It is executed in the following manner.
Let B gather up the string that joins his hands, pass the loop under the string that binds either of A’s wrists, slip it over A’s hand, and both will be free. By a reversal of the same process, the string may be replaced.
12. TO PULL A STRING THROUGH YOUR BUTTON-HOLE.
Take a piece of string about two feet in length, and tie the ends together. Pass it through a button-hole of your coat; hitch one thumb at each end, hook the little fingers into the upper strings of the opposite hand. Then draw the hands well outward, and the string will look very complicated, as in the [engraving].
To get out the string, loose the hold of the right thumb and left little finger, and separate the hands smartly, when the string will appear to have been pulled out through the substance of your coat.
