Mr. Bell describes an ass which belonged to his grandfather, who was so swift, that matches were made against him by the possessors of the fastest asses which could be found; but he beat them all, and even followed the hounds, coming up in gallant style, at the death of the fox. The well-known antipathy between the horse and the ass is scarcely to be explained, and has been often overcome; nevertheless, it always more or less exists, and many instances are on record in which it has caused inconvenience. One of these I can supply, which occurred when I was in Portugal. I started on a donkey to make a drawing of the great aqueduct which supplies Lisbon with its delicious water, and just as I had chosen my position, and established myself, my husband rode up on a beautiful and valuable horse, belonging to a friend. He wished to procure some specimens of the neighbouring rocks, and not liking to take a borrowed animal among them, he desired my donkey guide to hold his steed as well as mine. The boy obeyed; and Mr. Bowdich soon disappeared among the hollows. For a few minutes the horse stood quietly enough; but from the beginning he gave very significant glances at the companion forced upon him. At last he worked himself into a complete passion; snorted, pranced, reared, tossed his head, dilated his nostrils, and tried to reach the ass with his fore feet. He was prevented from doing this by the boy, who opposed him with much temper and courage; he then tried to turn round and kick the object of his indignation, who was by no means disposed to take the insult quietly. The boy let go the ass, who gave one fling at the horse, and then went very quietly to nibble the grass, lying in patches on the rough ground. The horse, however, now tried to get at the donkey; broke his bridle, pursued him, and both scampered off, the former doing just the very thing Mr. Bowdich wished to avoid. I was obliged to start up suddenly to get out of their way; my pencils and paper all made independent excursions, and the only thing to be done, was for me to catch the donkey, and the boy to catch the horse. Mine was much the easiest task; but both being accomplished, we kept them apart, the ass standing quietly enough, but the horse refusing to behave himself unless the boy mounted on his back, and rode him up and down on the smoothest path he could find. At length Mr. Bowdich returned, and thought all that had passed a good joke, in which I could not agree with him. He rode away; and I quietly finished my sketch.
