Take the horse’s left foot in your right hand; lift it up, and strike it
upon the ground, counting one, at the same time. Strike again, and count
two, and again, and count three, &c. to ten: when you pronounce this
last number, raise your voice, so that it will be a little more audible
than it was in the other numbers, and let the horse’s foot fall at the
same time. Now count fifteen, or any other number, in the same manner;
always telling the horse to count ten, fifteen, &c., and pronouncing the
number you tell in a more audible manner, letting his foot fall at the
same time. In a few lessons, he will learn to count at the word of
command, and will stop at any number, whenever you raise your voice a
little. In the same manner, you may make him tell what o’clock it is,
&c.
