Upwards and upwards we built, cutting windows in the trunk as we required, to admit light and air, until we were flush with the top of the centre pole. On this pole we erected another to reach the top of the tree, and securing it firmly, built in the same way round it until we at length reached the level of the floor of the nest above.
To make the ascent of the stairs perfectly easy we ran a hand-rail on either side, one round the centre pillar, and the other following the curve of the trunk.
This task occupied us a whole month, and by the end of that period, so accustomed had we become to having a definite piece of work before us that we began to consider what other great alteration we should undertake.
We were, however, of course not neglecting the details of our colonial establishment. There were all the animals to be attended to; the goats and sheep had both presented us with additions to our flock, and these frisky youngsters had to be seen after; to prevent them straying to any great distance, for we had no wish to lose them, we tied round their necks little bells, which we had found on board the wreck, and which would assist us to track them.
Juno, too, had a fine litter of puppies, but, in spite of the entreaties of the children, I could not consent to keep more than two, and the rest disappeared in that mysterious way in which puppies and kittens are wont to leave the earth. To console the mother, as he said, but also, I suspect, to save himself considerable trouble, Jack placed his little jackal beside the remaining puppies, and, to his joy, found it readily adopted.
The other pets were also flourishing, and were being usefully trained. The buffalo, after giving us much trouble, had now become perfectly domesticated, and was a very useful beast of burden, besides being a capital steed for the boys. They guided him by a bar thrust through the hole in his nose, which was now perfectly healed, and this served the purpose just as a bit in the mouth of a horse. I began his education by securing round him a broad girth of buffalo-hide and fastening to it various articles, to accustom him to carrying a burden. By degrees he permitted this to be done without making the slightest resistance, and soon carried the panniers, before borne by the ass, readily and willingly.
I then made Master Knips sit upon his back and hold the reins I had prepared for him, that the animal might become accustomed to the feeling of a rider, and finally allowed Fritz himself to mount.
The education of the eagle was not neglected. Fritz every day shot small birds for his food, and these he placed sometimes between the wide-spreading horns of the buffalo or goat, and sometimes upon the back of the great bustard, that he might become accustomed to pounce upon living prey.
These lessons had their due effect, and the bird, having been taught to obey the voice and whistle of his master, was soon allowed to bring down small birds upon the wing, when he stooped and struck his quarry in most sportsmanlike manner. We kept him well away from the poultry-yard lest his natural instincts should show themselves, and he should put an untimely end to some of our feathered pets.
Neither was Master Knips allowed to remain idle, for Ernest, now that he was in his possession, wished to train him to be of some use. With Jack's help he made a little basket of rushes, which he so arranged with straps that it might be easily fitted on to the monkey's back. Thus equipped he was taught to mount cocoanut palms and other lofty trees, and to bring down their fruit in the hamper.
