Some years ago, a donkey was employed at Carisbrook Castle, in the Isle of Wight, in drawing water by means of a large wheel from a very deep well, thought to have been sunk by the Romans. When the keeper wanted water, he would say to the donkey, “Tom, my boy, I want water; get into the wheel, my lad.” Thomas, thereupon, got in, with a speed and wisdom that would have done credit to a nobler animal. No doubt he knew the exact number of times the wheel had to turn upon its axis to bring up the bucket, because every time he brought it to the surface of the well, he stopped and turned round his honest head to note the moment when his master laid hold of the bucket to draw it toward him, because he had then a nice turn to make either to draw back, or to go ahead a little. It was pleasing to see with what steadiness and regularity the poor animal did his work.
