NOTE.
This very ingenious mode of secret writing is the most simple of any suggested by our author. A silk string of considerable length having been provided, it will be necessary to furnish the persons corresponding with a key or graduated gauge, by means of which the writing will be rendered intelligible. Having procured a duplicate or corresponding gauge it may then be commenced, 1/16 of an inch being allowed for the first letter, 1/4 for the second, 3/8 for the third, and so on, in equal proportions, through the whole alphabet. Should this arrangement be found to extend the line to an inconvenient length, it may be advisable to form a certain number of changes on three different lengths, as in No. LII.; though the former way is the least difficult.
No. XXXV.
The like by the fringe of gloves.
NOTE.
The principle of this and the four following Articles is the same as the preceding, with this difference, that in the first, the letters, or words, are formed by knotting the fringe, to which the gauge is afterwards applied; in the second, and most desirable way, the beads are set to the required distance; by the third, the gloves are pierced or pricked in rows, according to the divisions on the gauge; and by the fourth and fifth, the rows of parallel holes in a sieve or lantern are stopped at the required distances, and the gauge applied as before.
No. XXXVI.
