826 THE horse's RESCUE. 



badly and be made to vary in length by botch-work done on the feet 

 In order to show the principles the horse moves on I have liaod the 

 drive-wheels something like spokes in a wagon wheel; put the horso 

 in motion, each spoke as the wheel rolls will take its place at the point 

 T T ; all become in their turn perpendicular lines, C C ; tlie horso 

 clianges when in motion, feet at the point T T at the same time, if he 

 is all in harmony both forward and behind. When he is trotting fast 

 if you see when he changes if He is all right, jon will have to see 

 quick or you will not see when he does change. I do net pretend he 

 spaces off as he rolls along his strides, or steps regular as they are 

 spaced in this cut. 1 have marked some degrees on the forward drive- 

 wheel to show something of the action of the horse; these degrees I 

 did not put on the hind drive- wheel. The principle is the same on all 

 and on all horses, both before and behind ; and after you have experi- 

 mented on horses forty-one years, I am right, j'ou will find. The 

 horse when natural can place his forward foot to No. 12, and even 

 higher, the other foot remaining on the ground; he can do tlie same 

 with his hind feet; he can place his hind feet where F F circles cross 

 lines and form fulcrum at the top. I have marked off degrees, and 

 numbered them from 1 up to 12. They are not regularly spaced off. 

 These lines are to show the irregular change and degrees of change ou 

 the same horse. Do not forget it is the same on the horse's hind feet. 

 This will be more fully explained in other cuts. You can see I have 

 struck circles from the two centers of drive-wheels at the gambrel and 

 at the knee, M M. Look, then you can see at the fetlock there are 

 circles from the gambrel and knee, N N. Look ; these two you can 

 see. From the fetlock there is another circle from 0; and if you 

 destroy the structure in my foot, or feet, you will find I cannot go. 

 When the horse is put in motion he changes at point T T, and leg 

 folds toward the center of drive-wheel at the knee and fetlock and 

 heel. They fold the same on the hind drive-wheel, and these folding 

 cranks all fold toward the great center. A, and he gets the balance of 

 lever power in this way. When he reaches out his feet to put himself 

 in motion one half of his legs folds toward three centers, the other 

 half unfolds; he gets the balance of power. In this way the cranks 

 fold and unfold, striking half circles rotatory motion. The principles 

 are there just as much as they would be if this machine was made 

 with cog-gearing. He has got a power ou those drive-wheels. 

 When he is even with himself and in his circle, all natural as his crea- 

 tor made liim, he can straighten out his legs from A to K, and whirl
