of forty yards from the tank. They were forcing their way up
the knoll, and, had they not been intercepted first by the pelican and
afterwards by ourselves, they would in a few minutes have gained the
highest point and descended on the other side into a pool which formed
another portion of the tank. They were chub, the same as are found in
the mud after the tanks dry up." In a subsequent communication in July,
1857, the same gentleman says--"As the tanks dry up the fish congregate
in the little pools till at last you find them in thousands in the
moistest parts of the beds, rolling in the blue mud which is at that
time about the consistence of thick gruel."
"As the moisture further evaporates the surface fish are left uncovered,
and they crawl away in search of fresh pools. In one place I saw
hundreds diverging in every direction, from the tank they had just
abandoned to a distance of fifty or sixty yards, and still travelling
onwards. In going this distance, however, they must have used muscular
exertion sufficient to have taken them half a mile on level ground, for
at these places all the cattle and wild animals of the neighbourhood had
latterly come to drink; so that the surface was everywhere indented with
footmarks in addition to the cracks in the surrounding baked mud, into
which the fish tumbled in their progress. In those holes which were deep
and the sides perpendicular they remained to die, and were carried off
by kites and crows."
"My impression is that this migration takes place at night or before
sunrise, for it was only early in the morning that I have seen them
progressing, and I found that those I brought away with me in chatties
appeared quiet by day, but a large proportion managed to get out of the
chatties at night--some escaped altogether, others were trodden on and
killed."
"One peculiarity is the large size of the vertebral column, quite
disproportioned to the bulk of the fish. I particularly noticed that all
in the act of migrating had their gills expanded."]
Referring to the _Anabas scandens_, Mr. Hamilton Buchanan says, that of
all the fish with which he was acquainted it is the most tenacious of
life; and he has known boatmen on the Ganges to keep them for five or
six days in an earthen pot without water, and daily to use what they
wanted, finding them as lively and fresh as when caught.[1] Two Danish
naturalists residing at Tranquebar, have contributed their authority to
the fact of th
