Editor’s NoteCritical Apparatus1The rivers in Peru are observed to quicken their currents with the 2first approach of morning; an effect produced by the rays of the sun 3melting the snow upon the Andes. Similar appearances are striking 4among the Alps. At the head of the valley of Lauterbrunnen, in order 5to have a more perfect view of a magnificent waterfall, I crossed over 6a broad and rapid mountain torrent by the aid of the fragments of rock 7which strewed its bed. I did not stay above a few minutes; but on my 8return I found the difficulty of recrossing the stream much encreased; Critical Apparatus9and, being detained among the large stones in its channel, I perceived 10the water swell every moment, which, with the dizziness of sight 11produced by the furious dashing of the foam, placed me in a situation 12of considerable personal danger. Returning down the valley, from a 13bridge under the arch of which, about two hours before, for the sake of 14shade, we had retired to eat our dinner, we observed such a quantity Critical Apparatus15of water rolling over our late resting place as would have swept us Critical Apparatus16away before it. It will scarce be necessary to say that these temporary Critical Apparatus17floods will be found on different sides of a valley as the sun changes his 18position.
The brooks and rivers which cross the ways every step are so violent, that there is no head so strong, but it turns to look on their current … so that it is necessary sometimes to stay two or three days till the sun does not shine; for then these brooks are lower, because there is less snow melted: and for this reason it is always best to pass early in the morning, they having had all the night to run lower.
