There is no warbling, no song, only harsh noises, abrupt calls which those who haunt the forest soon learn to translate by two or three familiar words in Portuguese or English.

Seite 84 - After leaving the Cape Verde Islands the sea was a perfect blaze of phosphorescence. There was no moon, and although the night was perfectly clear and the stars shone brightly, the lustre of the heavens was fairly eclipsed by that of the sea.

Seite 10 - I know of no more perfect example of protective resemblance than that which is shown in the gulf -weed fauna. Animals drifting about on the surface of the sea with such scanty cover as the single broken layer of the sea-weed, must be exposed to exceptional danger from the sharp-eyed sea-birds hovering above them, and from the hungry fishes searching for prey beneath ; but one and all of these creatures imitate in such an extraordinary way, both in form and colouring, their floating habitat, and consequently...
Seite 147 - On one occasion he describes (p. 147) the loss of a great catch, when trawling at a depth of 2,350 fathoms in the South Atlantic. " The trawl was lowered, and on heaving in it came up apparently with a heavy weight, the accumulators being stretched to the utmost. It was a long and weary wind-in on account of the continued strain ; at length it came close to the surface, and we could see the distended net through the water ; when, just as it was leaving the water, and so greatly increasing its weight,...
Seite 352 - ... upon certain causes affecting the composition of the bottom deposits, and of the bottom water involving the supply of oxygen, and of carbonate of lime, phosphate of lime, and other materials necessary for their development, than upon any of the conditions immediately connected with depth. 3. There is every reason to believe...
Seite 143 - ... cries of a child, followed by low meanings, rang out from under the wheels, and a jerk of the drag pulled the car up and nearly threw us out of our seats. -We jumped out and looked nervously under the wheels to see what had happened, but there was no child there.
