After you have trained him in this way, which should not take you more than one or two hours, you can ride him any where you choose without ever having him jump or make any effort to throw you.
When you first take him out of the stable be very gentle with him, as he will feel a little more at liberty to jump or run, and be a little easier frightened than he was while in the stable. But after handling him so much in the stable he will be pretty well broke, and you will be able to manage him without trouble or danger.
When you first mount him take a little the shortest hold on the left rein, so that if any thing frightens him you can prevent him jumping by pulling his head around to you. This operation of pulling a horse's head around against his side will prevent any horse from jumping ahead, rearing up, or running away. If he is stubborn and will not go you can make him move by pulling his head around to one side, when whipping would have no effect. And turning him around a few times will make him dizzy, and then by letting him have his head straight, and giving him a little touch with the whip, he will go along without any trouble.
Never use martingales on a colt when you first ride him; every movement of the hand should go right to the bit in the direction in which it is applied to the reins, without a martingale to change the direct of the force applied. You can guide the colt much better without them, and learn him the use of the bit in much less time. Besides, martingales would prevent you from pulling his head around if he should try to jump.
After your colt has been rode until he is gentle and well accustomed to the bit, you may find it an advantage if he carries his head too high, or his nose too far out, to put martingales on him.
You should be careful not to ride your colt so far at first as to heat, worry or tire him. Get off as soon as you see he is a little fatigued; gentle him and let him rest, this will make him kind to you and prevent him from getting stubborn or mad.
The proper way to Bit a Colt.
Farmers often put bitting harness on a colt the first thing they do to him, buckling up the bitting as tight as they can draw it to make him carry his head high, and then turn him out in a lot to run a half day at a time. This is one of the worst punishments that they could inflict on the colt, and very injurious to a young horse that has been used to running in pasture with his head down. I have seen colts so injured in this way that they never got over it.
A horse should be well accustomed to the bit before you put on the bitting harness, and when you first bit him you should only rein his head up to that point where he naturally holds it, let that be high or low; he will soon learn that he cannot lower his head, and that raising it a little will loosen the bit in his mouth. This will give him the idea of raising his head to loosen the bit, and then you can draw the bitting a little tighter every time you put it on, and he will still raise his head to loosen it; by this means you will gradually get his head and neck in the position you want him to carry it, and give him a nice and graceful carriage without hurting him, making him mad, or causing his mouth to get sore.
If you put the bitting on very tight the first time, he cannot raise his head enough to loosen it, but will bear on it all the time, and paw, sweat and throw himself. Many horses have been killed by falling backward with the bitting on, their heads being drawn up, strike the ground with the whole weight of the body. Horses that have their heads drawn up tightly should not have the bitting on more than fifteen or twenty minutes at a time.
