Highlanders playing in the centre, and their pipers walking about the grounds ready to take up the strains of music in another key, for presently we saw them marching about, playing "Hielan' Skirls," and sounding the loud pibroch, with a five-bag power that was more stunning than the nocturnal wailings of a dozen or two Kilkenny cats. The directors furnish music and offer other inducements to secure a good attendance, and their efforts ought to be successful, and it is to be hoped they will be so. On the first day of our visit there was a grand archery meeting, and the turn-out of Dublin belles was double in numbers. There was a large attendance of bowmen, too, and belles and beaux were banging away at the targets most unmercifully in keen contest for the prize; whether it was a medal, a ring, or an heiress, we could not learn; but if nothing more than the privilege of entering the lists against such lovely competitors, the bowmen ought to have been satisfied; but we don't suppose they were, for men are both ambitious and avaricious, and probably some of them hoped to win a prize medal, kill a beauty, and catch an heiress all at once, with one swift arrow sent whizzing and quivering into the very heart and gilded centre of the gaily-painted target. Perched up on the top of the cascades we noticed a double sliding-front stereoscopic camera, and doubtless Mr. York was busy photographing the scene we have been describing--impressions of which the London Stereoscopic Company will probably issue ere long. We must, however, leave this gay scene and turn our attention to other things, certainly not more attractive; but duty calls us away from beauty, and we must submit. Re-entering the Exhibition building, we seek the photographic department, which we readily find on the ground floor, between the music hall and the first-class refreshment-room. Entering from the Belgian department in the western transept, we find three rooms in the main building devoted to the exhibition of photographs, and a lobby between the rooms pretty well filled with apparatus. To Sir J. Jocelyn Coghill are photographers indebted for obtaining so much space for their works, and in such a get-at-able situation; but it is a pity the rooms are not better lighted. Many of the pictures on the screens are very indistinctly seen, and some are in dark corners scarcely to be seen at all. The foreign department, which is the first room we enter, is mainly made up of reproductions of old and modern engravings, and copies of drawings and paintings. One very remarkable photograph on the wall of this room is an immense magnification of a flea, by A. Duvette. What a subject for the camera!--one that suggests in sporting phraseology something more than the "find," the "chase," and the "death."
