5. BLACK 
CHIN. 
BLACK CHIN GREBE. Crass IL, 
which they do with great swiftness, and continue — 
long under water. Their food is fish, and water 
plants. This bird is found in rivers, and other 
fresh waters; it forms its nest near their banks, 
in the water ; but without any fastening, so that 
it rises and falls as that does. To make its nest 
it collects an amazing quantity of grass, water- 
plants, &c. It lays five or six white eggs, and 
always covers them when it quits the nest. It — 
should seem wonderful how they are hatched, © 
as the water rises through the nest, and keeps — 
them wet; but the natural warmth of the bird 
bringing on a fermentation in the vegetables, 
for the purpose.
