"My dear, conscientious father," said Margaret, "be comforted; I trust the hour may yet come when you will have a field for your pious labors: till then, have no remorse in following your simple and blameless amusements. I have no merit in my duties of attending, governing, and lecturing these wild boys. I love the office; I was certainly not born for any sphere more elevated. But you, papa, whose sole enjoyment is to sit in an easy-chair before a table laden with books and a cabinet filled with eggs and wings, were wrenched violently from your nature when you were doomed to pass days in forcing these unwilling boys to learn the rules of syntax, or the crabbed mysteries of Euclid. We are shaken from our proprieties here; you cannot teach Latin or work out problems without books; so you must take your ease, and consider this the long vacation."

"You are the girl for knowing a few things, Meggie!" said O'Brien, admiringly. "Be sure, sir, Hugh and I will work to any amount to help you in your ornithology and oology, if you will spare us the philology a bit. There's no running about with a conjugation in one's mouth."

"And as Arthur has demonstrated his problem on the best position for the encampment," said Hugh, "I conclude we had better move at once. No occasion to send forward notice about well-aired beds."

"And no occasion, Hugh Harebrain," said Arthur, "to be overtaken by darkness on our journey. Let us be deliberate. Jenny must roast the ducks for our breakfast in the morning, Jack must collect his valuable work-tools, Ruth must again imprison those luckless chickens, and then we must all have a night's rest. It will be time enough to set out in the morning, and we must take care to start before the sun blazes out in all its fervor."

All obeyed orders; and, with the first ray of light, the whole camp was alive. It was very important this time that nothing should be left behind. Peter had relieved them from the charge of biscuit and water, which he had carried off with the tool-chest and gun; but there was still a little tea and sugar, which was carefully preserved. The sail-cloth was rolled up; even the oars used for tent-poles were taken; and, after morning prayers, they set out slowly along the beach, and through the mazy, ascending woods, till they reached the table-land of the rocky isle. They crossed it this time at the head of the lake which they had discovered the preceding day, and found this part of the island still more fertile and lovely than any they had yet seen. Mr. Mayburn was in ecstasy; he stopped continually to point out some new and beautiful grass, some bright nameless flower, or some strange tree; while the notes, harsh, musical, or merry, of thousands of birds, filled him with amazement and delight.

"From this moment, my boys," said he, "I release you from the severe studies which, Margaret truly observes, are unfitted to our circumstances and the relaxing climate. I merely require from you to obtain me specimens—single specimens only—of the eggs and nests of these birds; and, if it were not cruel, I should long to possess some of these rare creatures in all their beauty."

"I fear, papa," observed Margaret, "that you have no means of preserving birds; therefore it would be useless to take them."

"You are right, Margaret," he answered. "I will be content with a nest and an egg of each species."

"Would you mind about having the nest and egg of that fellow, sir?" asked O'Brien, pointing to a majestic black swan sailing on the lake.

"Rara avis!" exclaimed he; then added, with a sigh, "no, no, Gerald, we have no means. The animal is weighty, therefore the nest must be large, and not of a portable nature. I relinquish the precious possession. But let us linger on the borders of the lake, to examine its wild charms. Would that I had saved my botanical library, that I might have made out the species of these broad flags and thick bamboos!"
