_June 30._--Iceberg! An iceberg! The real thing at last! We left Henley at ten A. M., and were soon coming up with a noble berg. Its aspect, on our near approach, was that of a vast roof rising at one end, beside which, and about half its height, was the upper third of an enormous cylinder. Passing to the west, along one side of this roof, we beheld a vast cavernous depression, making a concave line in its ridge, and then dipping deep, beyond view, into the berg. The sharp upper rim of this depression came between us and the sky, with the bright shine of the forenoon sun beyond, and showed a skirt or fringe of infinitely delicate luminous green, whose contrast with the rich marble-white of the general structure was beautiful exceedingly. With the exception of this, and of a narrow blue seam, looking like lapis-lazuli, which ran diagonally from summit to base, the broad surface of this side had the look of snow-white marble lace or fretwork. Passing thence to the north face, we came apparently upon the part at which the berg separated from its parent glacier. Here was a new effect, and one of great beauty. In material it resembled the finest statuary marble,--but rather the crystalline marbles of Vermont, with their brilliant half-sparkle, than the dead polish of the Parian; while the form and character of this facade suggested some fascinating, supernatural consent of chance and art, of fracture with sculpturesque and architectural design. "He works in rings, in magic rings, of chance,"-- the subtlest thing ever said of Turner,--might have been spoken even more truly of the workman who wrought this. The apparent fineness of material cannot be overstated, so soft and powerful. "A porcelain fracture," said Ph----,--well. Yet such porcelain! It were the despair of China. On the eastern, or cylinder side, there was next the water a strip of intensely polished surface, surmounted by an elaborate level cornice, and above this the marble lace again.
