 of the lower one almost touches it. All this time the other male bird is quite near, but seems to take little notice of the performance. At length the frenzied one desists from his madness of motion, and the two now hop about over the warren as before, closely in each other's company. In some ten minutes or so there is the same display—or rather frenzy—but whether made by the same bird or the other one I am unable to say. This time it commences on the even turf and not in a hollow, but after a few throws the bird finds one and throws, thenceforth, over that." I have seen, I think, a Japanese acrobat throw a wonderful succession of somersaults backwards and forwards within his own length. With the bird there was no somersault, but the effect was something the same. The man's body also presented the appearance of an arch in the air (as when one vibrates a lighted joss-stick from side to side), but, as the bird moved much more quickly, the resemblance in its case was more perfect.

"Once or twice again, now, one of the two birds acts in the same way, always seeming to prefer to do so over a depression in the ground. One then flies up a little way into the air, descends again, and, on alighting, instantly recommences as before, again, I think, over a slight hollow. The motion is equally violent, but not so long continued, some seven or eight flings, perhaps, in all. At the end of it he stops still, advances the head straight forwards, lowering it a trifle, swells the feathers, and broadly fans the tail. Then the two birds fly at each other, but almost in the act of closing they part, with a little twitter, and commence hopping over the warren
