Von Bloom now reflected that the hyenas were likely to prove a great pest to him. No meat, nor anything, would be safe from them—even his very children would be in danger, if left alone in the camp; and no doubt he would often be compelled to leave them, as he would require the older ones upon his hunting excursions.

There were other animals to be dreaded still more than the hyenas. Even during that night they had heard the roaring of lions down by the vley; and when it was morning, the spoor showed that several of these animals had drunk at the water.

How could he leave little Trüey—his dear little Trüey—or Jan, who was not a bit bigger—how could he leave them in an open camp while such monsters were roving about? He could not think of doing so.

He reflected what course he should pursue. At first he thought of putting up a house. That would necessarily be a work of time. There was no good building material convenient. A stone house would cost a great deal of labour—as the stones would have to be carried nearly a mile, and in their hands too. That would never do, as Von Bloom might only remain a short while at that place. He might not find many elephants there, and of course would be under the necessity of going elsewhere.

Why not build a log-house? you will say. That would not be so much of a job, as part of the country was well wooded, and they had an axe.

True, part of the country was wooded, but in a particular manner. With the exception of the nwana-trees, that stood at long distances apart—and regularly, as if they had been planted—there was nothing that deserved the name of timber. All the rest was mere “bush,”—a thorny jungle of mimosas, euphorbias, arborescent aloes, strelitzias, and the horrid zamia plants, beautiful enough to the eye, but of no utility whatever in the building of a house. The nwanas, of course, were too large for house-logs. To have felled one of them would have been a task equal almost to the building of a house; and to have made planks of them would have required a steam saw-mill. A log-house was not to be thought of either.

Now a frail structure of poles and thatch would not have given sufficient security. An angry rhinoceros, or elephant, would level such a house to the ground in a few moments.

Suppose, too, that there were man-eaters in the neighbourhood. Swartboy believed that there were, and that that region was notorious for them. As it was not far from Swartboy’s native country, Von Bloom, who had reason to believe what the Bushman told him, was inclined to credit this. What protection would a frail house afford against the man-eater? Not much, indeed.

Von Bloom was puzzled and perplexed. He could not commence his hunting excursions until this question was settled. Some place must be prepared, where the children would be safe during his absence.

While revolving the subject in his mind, he happened to cast his eyes upward among the branches of the nwana-tree. All at once his attention became fixed upon those huge limbs, for they had awakened within him a strange memory. He remembered having heard that, in some parts of the country, and perhaps not very far from where he then was, the natives live in trees. That sometimes a whole tribe, of fifty or more, make their home in a single tree; and do so to secure themselves against savage beasts, and sometimes equally savage men. That they build their houses upon platforms, which they erect upon the horizontal branches; and that they ascend by means of ladders, which are drawn up after them at night when they go to rest.

All this Von Bloom had heard, and all of it is positively true. Of course the reflection occurred to him, why could he not do the same? Why could he not build a house in the gigantic nwana? That would give him all the security he desired. There they could all sleep with perfect confidence of safety. There, on going out to hunt, he could leave the children, with the certainty of finding them on his return. An admirable idea!—how about its practicability?

He began to consider this. If he only had plan............
