the Rhone there enters it, that the lake is in fact a kind of expansion of the river. Follow this upwards; you find it joined by smaller rivers from the mountains right and left. journey higher still. You Pass these, and push your come at length to a huge mass of ice-the end of a glacier-which fills the Rhone valley, and from the bottom of the glacier the river rushes. In the glacier of the Rhone you thus find the source of the river Rhone. 7. But again we have not reached the real beginning of the river. You soon convince yourself that this earliest water of the Rhone is produced by the melting of the ice. You get upon the glacier and walk upwards along it. After a time the ice disappears and you come upon snow. If you are a competent mountaineer you may go to the very top of this great snow-field, and if you cross the top and descend at the other side you finally quit the snow, and get upon another glacier called the Trift, from the end of which rushes a river smaller than the Rhone. 8. You soon learn that the mountain snow feeds the glacier. By some means or other the snow is converted into ice. But whence comes the snow? Like the rain, it comes from the clouds, which, as before, can be traced to vapour raised by the sun. Without solar fire we could have no atmospheric vapour, without vapour no clouds, without clouds no snow, and without snow no glaciers. Curious then as the conclusion may be, the cold ice of the Alps has its origin in the heat of the sun. John Tyndall. EXERCISES.-1.

[These verses are by the poet William Cowper, and are intended to express the thoughts that may have occurred to Alexander Selkirk, a Scottish sailor who spent some years, 1704-1708, in perfect solitude on the small and uninhabited isle of Juan Fernandez, in the Pacific Ocean, off the coast of South America. Selkirk's history suggested to Defoe the idea of Robinson Crusoe.] My right there is none to dispute; I am lord of the fowl and the brute. That sages have seen in thy face? 2. I am out of humanity's reach, I must finish my journey alone; They are so unacquainted with man, 3. Society, Friendship, and Love, In the ways of religion and truth- 4. Religion! what treasure untold Resides in that heavenly word! More precious than silver and gold, Or smiled when a Sabbath appeared. 5. Ye winds, that have made me your sport, Convey to this desolate shore Some cordial endearing report Of a land I shall visit no more. 6. How fleet is a glance of the mind! And the swift-wingèd arrows of light. Soon hurries me back to despair. 7. But the sea-fowl is gone to her nest, And I to my cabin repair. And reconciles man to his lot. Cowper. |
