I also noted several scored and polished patches on the hardest and most enduring of the outswelling rock bosses. This little island, standing as it does alone out in the Polar Sea, is a fine glacial monument. A MIDNIGHT OBSERVATION. The midnight hour I spent alone on the highest summit, one of the most impressive hours of my life. The deepest silence seemed to press down on all the vast, immeasurable, virgin landscape. The sun near the horizon reddened the edges of belted cloud bars near the base of the sky, and the jagged ice bowlders crowded together over the frozen ocean stretching indefinitely northward, while more than a hundred miles of that mysterious Wrangell Land was seen blue in the northwest--a wavering line of hill and dale over the white and blue ice prairie and pale gray mountains beyond, well calculated to fix the eye of a mountaineer; but it was to the far north that I ever found myself turning, where the ice met the sky. I would fain have watched here all the strange night, but was compelled to remember the charge given me by the captain, to make haste and return to the ship as soon as I should find it possible, as there was ten miles of shifting, drifting ice between us and the open sea. PLANT LIFE ON HERALD ISLAND. I therefore began the return journey about one o'clock this morning, after taking the compass bearings of the principal points within sight on Wrangell Land, and making a hasty collection of the flowering plants on my way. I found one species of poppy, quite showy, and making considerable masses of color on the sloping uplands, three or four species of saxifrage, one silene, a draba, dwarf willow, stellaria, two golden compositae, two sedges, one grass, and a veronica, together with a considerable number of mosses and lichens, some of them quite showy and so abundant as to form the bulk of the color over the gray granite. INHABITANTS OF THE CLIFFS. Innumerable gulls and murres breed on the steep cliffs, the latter most abundant. They kept up a constant din of domestic notes. Some of them are sitting on their eggs, others have young, and it seems astonishing that either eggs or the young can find a resting place on cliffs so severely precipitous. The nurseries formed a lively picture--the parents coming and going with food or to seek it, thousands in rows standing on narrow ledges like bottles on a grocer's shelves, the feeding of the little ones, the multitude of wings, etc. * * * * * M. Bouchut's experiments with pepsine for destroying worms in the stomach and bowels have been continued with extremely promising results. Even the tapeworm succumbs to the digestive action of pepsine in large doses, while the more highly organized tissues of the stomach are unaffected. * * * * * FRANZ LISZT.
