Plack Stall Dectorum 24Many of the smaller species of fishes, upon leaving these winter resorts, ascend small, clear brooks in large numbers for the purpose of depositing their eggs; as, when hatched in such a place, the young will be comparatively free from the attacks of the larger carnivorous forms. Among the lowest vertebrate often found in numbers in early spring in these meadow rills and brooks is the lamprey, _Ammocoetes branchialis_ (L.), or "lamper eel," as it is sometimes called. It has a slender eel-like body, of a uniform leaden or blackish color, and with seven purse-shaped gill openings on each side. The mouth is fitted for sucking rather than biting, and with it they attach themselves to the bodies of fishes and feed on their flesh, which they scrape off with their rasp-like teeth. Later in the season they disappear from these smaller streams, probably returning in midsummer to deeper water. Thoreau, who studied their habits closely, says of them: "They are rarely seen on their way down stream, and it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature to the scenery of the river bottoms worthy to be remembered with Shakespeare's description of the sea floor." The water of the stream was of a dirty yellow, and very turbulent owing to the strong wind that was blowing and the violent current. Proceeding up stream, we then came to a hill 300 ft. high on the right, which ended abruptly in an almost vertical red and yellow cliff plunging into the water. On the opposite side of the river, along the narrow neck, were lowlands, quite open and scantily wooded, over which rose great columns of black smoke, caused by the natives burning down the forest in order to prepare the land for their plantations. It was at this point that the entire volume of the Amazon could be gauged at a glance. As you looked up stream a long bluish line of low forest could be perceived over the gradually expanding deep yellow river. Dozens upon dozens of columns of smoke were visible. When night came the effects of those forest fires, with the reflection of the light upon the low clouds and in the water, were very weird and beautiful. | |
