to the open outer edge where the stunted trees and bushes die away on the border of the savannah, what was my delight and astonishment at hearing the mysterious melody once more! It seemed to issue from a clump of bushes close by; but by this time I had come to the conclusion that there was a ventriloquism in this woodland voice which made it impossible for me to determine its exact direction. Of one thing I was, however, now quite convinced, and that was that the singer had been following me all the time. Again and again as I stood there listening it sounded, now so faint and apparently far off as to be scarcely audible; then all at once it would ring out bright and clear within a few yards of me, as if the shy little thing had suddenly grown bold; but, far or near, the vocalist remained invisible, and at length the tantalising melody ceased altogether.
