Revolving Telegraph. 107 
If figures are the medium of communication, then one 
to ten respectively designate the decimal figures. Eleven 
may represent 0; twelve, 100; thirteen, 1000; and each 
may he read as shall be agreed on. Thus a dictionary 
of words or sentences, numbered to any amount, may he 
constituted, in which such as are not often necessary may 
be omitted altogether. Now, by giving such a particular 
number, all that is required is to look for that number, 
and we have the corresponding word or sentence. The 
figures maybe written down of each number as found ; thus, 
1250 ; — number 1 3, one thousand ; number 2, two ; number 
12, hundred; number 5, five; number 11, 0. By this 
or other means which experience may suggest, any num- 
ber may be readily found, and the corresponding sense 
discovered. The key of this system may be easily 
changed daily, weekly, &c. by adding to, or subtracting 
from the number found, a certain specified number ; as 
ten, twenty, thirty, &c. and regarding the residuary num- 
ber as the one to be looked for in the telegraphic dic- 
tionary. 
It will readily be seen, that I have only here given a 
slight outline of the nature of the mode of communication, 
leaving it to those who may consider the subject practi- 
cally, to fix upon the plan best adapted to their inten- 
tions. 
I have only to add, that I have constructed a small 
telegraph upon the above plan, about one sixth the natu- 
ral size, (which I have supposed to be twelve feet,) that 
works readily and appropriately, although by no means 
fitted with the various pullies, &c. to facilitate the mo- 
tion of the ropes. The engraving made from a drawing 
of this model, is on a scale of about three eighths of an 
inch to a foot
