satisfactory. But having watched what had been taking place for a full half-hour at only three paces distance, and as, on the bird's return, it would have been too dark to see anything more, I thought I would assist them, and so smoothed down the declivity, and laid the eggs side by side on a flat surface. I must add that while the bird was thus struggling to extricate its egg it uttered from time to time a low querulous note.

At about ten one of the birds settled on a bush just in front of me, and sat there silently for some ten minutes, then flew and settled on the ground near eggs for a minute or two, and whilst there uttered a low guttural note. Finally, at 10.13, it came and settled itself quietly on to the eggs as I had placed them. This and my subsequent observations make me think that it was not the bird that had got into difficulties, but the other and more skilful one—the hen, no doubt—the cock bird being less perfect in the art of incubating.

June 26th.—Reached bush at 8.22 p.m., and found the bird sitting in the same position as night before. It seemed to be asleep, the eye being fast shut. The eggs appeared to have been moved slightly to one side, judging by where the bird sat.

8.34—Sitting bird relieved. Process exactly the same as on night before. The relieving bird came from neighbouring plantation quaw-eeing, and when near was answered by a gentle "churr" from the brooding bird. This latter's head was turned the other way, so that she could not have seen her mate as he flew up. Moreover, she opened her eyes for the first time at his "quaw-ee."

The new-come bird settled himself beside the brooding one as on previous night (same distance apart), and both of them churred, gently wagging their bodies from side to side. Then in a few seconds the relieved bird flew away (I think silently), and was followed a few seconds afterwards by the other one, which had not moved on to the eggs, or from where it had alighted. Upon going round the bush and looking at the eggs, I could not feel certain that they had been moved from where I placed them the previous night. The distance, I find, from where I sit to the eggs is just three paces.

8.53.—Bird flew near, and would have perched on the same little bush (just in front of me) as last night, but it saw me, I think, and, very little startled, settled on ground close by.
