Like all horses that have grown up, I had to wear a bit and bridle, A bit is a great piece of cold hard metal, as thick as a man's finger, which is pushed into a horse's mouth between his teeth and over his tongue, with the ends coming out at the corners. It is held there by straps which go over the horse's head, under his neck, round his nose and under his chin. Reins, which the rider holds, are fastened to each end of the bit. Slowly, with my master's kind words and gentle ways, I learned to wear my bit and bridle.
