For every thing that we get him to do of his own accord

For every thing that we get him to do of his own accord

Now, reader, can you, or any one else, give one single reason how scent can convey any idea to the horse's mind of what we want him to do? If not, then of course strong scents of any kind are of no account in taming the unbroken horse. For every thing that we get him to do of his own accord, without force, must be accomplished by some means of conveying our ideas to his mind. I say to my horse "go 'long" and he goes; "ho!" and he stops: because these two words, of which he has learned the meaning by the tap of the whip, and the pull of the rein that first accompanied them, convey the two ideas to his mind of go and stop.
