To Tell By A Watch Dial The Hour When A Person Intends To Rise
The person is told to set the hand of his watch at any hour he
pleases, which hour he tells you; and you add in your mind 12 to it.
You then desire him to count privately the number of that addition on
the dial, commencing at the next hour to that at which he intends to
rise, and including the hour at which he has placed the hand, which
will give the answer: for example.
A intends to rise at 6, (this he c
nceals to himself;) he places the
hand at 8, which he tells B, who, in his own mind, adds 12 to 8, which
makes twenty. B then tells A to count twenty on the dial, beginning at
the next hour to that at which he proposes to rise, which will be 5,
and counting backwards, reckoning each hour as one, and including in
his addition the number of the hour the hand is placed at, the
addition will end at 6, which is the hour proposed; thus,
The hour the hand is placed at is 8
The next hour to that which A intends to rise at is 5, which
counts for 1
Count back the hours from 5, and reckon them at 1 each, there
will be 11 hours, viz., 4, 3, 2, 1, 12, 11, 10, 9, 8, 7, 6 11
