On the other hand, he must not be allowed to escape to the Italian colony with news of the disaster.
At some future time, and from a safe distance, it might be possible to obtain a large ransom for him; or, on the other hand, if a large force were ever sent up the country to revenge the outrage, it might be to the credit of the chief if he could prove that the deed had been done without his knowledge and that he had treated the only survivor humanely.

He therefore took possession of Giovanni and provided for his safety in a simple manner by merely stating that if the prisoner escaped he would cut off ten heads, but if any harm came to him, he would cut off at least a hundred.

As no one doubted but that he would keep his word, as he invariably did in such matters, Giovanni had but small chance of ever regaining his liberty, and none at all presented itself for nearly five years.

During that time he travelled with his captors or lived in camps, many hundreds of miles from the outposts of civilisation; he learned their language and the chief insisted on learning his, as it might be useful; furthermore, he was required to teach his master whatever he could about modern warfare and what little he knew of agriculture and its arts of peace.

In return he was well fed, well lodged when possible, and as well clad as any man in the tribe except the chief himself, which was not saying much.
His chance came at last and he did not let it pass.
