Tom and Desmond accordingly, who had wished to explore the end of the island not hitherto visited, set off with their guns the next morning. They had not gone far when they found themselves among numbers of birds, a large portion of which had made their nests on the ground. It appeared that for some reason or other they had selected the southern end of the island. Most of them were so tame that they refused to move, and attacked the midshipmen’s legs with their beaks. Among them were gannets, sooty terns, and tropical birds in large numbers. The gannets sat on their eggs croaking hoarsely, not moving even when the midshipmen attempted to catch them. There were also frigate birds which had built their nests, in the lower trees, of a few sticks roughly put together. They sat for some time watching the trespassers on their domain, then spreading their wings flew off, inflating their blood-red bladders, which were of the size of the largest cocoa-nuts, to aid them in their ascent though the air.

“We need not expend any powder and shot on these fellows,” observed Desmond; “and all we have to do is to wring the necks of as many as we want for our use, and take the eggs.”

“Let us ascertain how long the eggs have been sat upon, or we may have the trouble of carrying them for nothing,” answered Tom.

They went forward, expecting to get beyond the region of birds, but instead, the nests grew thicker and thicker; indeed, the midshipmen’s progress was almost stopped at times, as they had to dodge in and out and skip here and there to avoid the attacks made on their legs.

“We need have no fear of starving, although we might in time get tired of poultry,” said Desmond.

At last they came to a lower part of the island, over which the sea occasionally washed. It had been avoided by the wise birds, but still had its inhabitants. Whole armies of soldier-crabs were marching about in every direction with their shells on their backs, as well as common crabs on the watch for lizard or snake-like creatures which ventured among them. Sometimes, when a big crab had got hold of one of these, and its attention was occupied in carrying off its prey, a frigate bird would pounce down and seize it, carrying both it and its captive off to its nest.

The midshipmen were so amused that they could not tell how time passed, until hunger and the hot sun reminded them that it was the time when dinner would be ready; and passing through the “farm-yard,” as Desmond called it, they secured as many birds as they could carry and also filled their pockets with the freshest-looking eggs they could find. Desmond, giving a wink to Tom, put among them a couple from a nest over which the mother bird had fought stoutly, and which certainly did not look very fresh. “I can almost hear it croak,” he said, placing an egg to his ear. “I intend these as a bonne-bouche for Billy. We won’t show the others, and will make him suppose that we especially favour him by bringing these, knowing how fond he is of eggs.”

Gerald kept to his intention. As nobody was in the hut when they got back, they hid away all the eggs with the exception of two, which Desmond so kindly selected for his messmate. Peter was engaged in cooking, and having his stew ready, he shouted to announce the fact.

They hurried in, for all were hungry and eager again to begin work. Tom and Desmond showed their birds, and described the numbers they had met with.

“Did you bring any eggs?” asked the doctor; “they can be cooked at once, and are likely to prove better flavoured than the birds themselves.”
