edges are sharp as knives from the centre to the upper point; but from the centre to the end which is joined to others, the sharp edge is replaced by a smooth surface, as though a cut had been made with a razor. The upper ends of these prisms are clear as glass; the lower ends are a little cloudy. The brilliancy of the combination is marvellous. CHAPTER XXX. GENERAL IMPRESSIONS. When the Queen of Sheba heard of the fame of Solomon she went to Jerusalem with a great train, with camels that bore spices and large quantities of gold and precious stones, and fully satisfied the curiosity commonly attributed to her sex. She proved the wisdom of the far-famed monarch, admired his house and its appointments, the apparel of his servants, the attendance of his ministers, and the magnificence of his daily table; and, according to Josephus, she said: "As for the report, it only attempted to persuade our hearing, but did not so make known the dignity of the things themselves as does the sight of them, and being present among them. I, indeed, who did not believe what was reported by reason of the multitude and grandeur of the things I inquired about, do see them to be much more numerous than they were reported to be." Or, as the verdict of "the Queen of the South" is given in the Authorized Version of the Old Testament, "I believed not the words until I came, and mine eyes had seen it; and, behold, the half was not told me." A similar testimony will be borne by most visitors in regard to the magnificence of the Jenolan Caves, and "the multitude and grandeur" of the objects which excite surprise or challenge admiration at almost every step. Jenolan is a veritable wonderland, as well as a most interesting geological study. It presents features sufficiently sublime to touch the deepest chords of the human heart: forms sufficiently graceful to charm the artist; situations affording novel material for the romancist; configurations, transmutations, and fascinations to move the soul of the poet; and vast, silent cathedrals which inspire a feeling of devotion, for-- "Nature, with folded hands, seems there Kneeling at her evening prayer."
