against the Admiral; in whose neighbourhood we
shall unfortunately hear of them again.

In the meantime their departure had somewhat relieved the condition of
affairs on board the hulks. There were more provisions and there was
more peace; the Admiral, rising above his own infirmities to the
necessities of the occasion, moved unweariedly among the sick, cheering
them and nursing them back into health and good humour, so that gradually
the condition of the little colony was brought into better order and
health than it had enjoyed since its establishment.

But now unfortunately the evil harvest sown by the Porras gang in their
journey to the east of the island began to ripen. The supplies of
provisions, which had hitherto been regularly brought by the natives,
began to appear with less punctuality, and to fall off both in quantity
and quality. The trinkets with which they were purchased had now been
distributed in such quantities that they began to lose their novelty and
value; sometimes the natives demanded a much higher price for the
provisions they brought, and (having by this time acquired the art of
bargaining) would take their stores away again if they did not get the
price they asked.

But even of this device they soon grew weary; from being irregular, the
supplies of provisions from some quarters ceased altogether, and the
possibilities of famine began to stare the unhappy castaways in the face.
It must be remembered that they were in a very weak physical condition,
and that among the so-called loyal remnant there were very few who were
not invalids; and they were unable to get out into the island and forage
for themselves. If the able-bodied handful were to sally forth in search
of provisions, the hulks would be left defenceless and at the mercy of
the natives, of whose growing hostility the Admiral had by this time
discovered abundant evidence. Thus little by little the food supply
diminished until there was practically nothing left, and the miserable
company of invalids were confronted with the alternative of either dying
of starvation or desperately attempting a canoe voyage.

It was from this critical situation that the spirit and resource of
Columbus once more furnished a way of escape, and in these circumstances
that he invented and worked a device that has since become famous--the
great Eclipse Trick. Among his small library in the cabin of the ship
was the book containing the astronomical tabl
