He spent a good portion of his time on Jerry’s education, and, on occasion, would make bows and arrows that were so esteemed by his tribespeople as to command a steady sale.  Scarcely a day passed in which he did not himself practise with bow and arrow.  He shot only by direction of sound; and whenever a noise or rustle was heard in the jungle, and when Jerry had informed him of its nature, he would shoot an arrow at it.  Then it was Jerry’s duty cautiously to retrieve the arrow had it missed the mark.

A curious thing about Nalasu was that he slept no more than three hours in the twenty-four, that he never slept at night, and that his brief daylight sleep never took place in the house.  Hidden in the thickest part of the neighbouring jungle was a sort of nest to which led no path.  He never entered nor left by the same way, so that the tropic growth on the rich soil, being so rarely trod upon, ever obliterated the slightest sign of his having passed that way.  Whenever he slept, Jerry was trained to remain on guard and never to go to sleep.

Reason enough there was and to spare for Nalasu’s infinite precaution.  The oldest of his three sons had slain one, Ao, in a quarrel.  Ao had been one of six brothers of the family of Anno which dwelt in one of the upper villages.  According to Somo law, the Anno family was privileged to collect the blood-debt from the Nalasu family, but had been balked of it by the deaths of Nalasu’s three sons in the bush.  And, since the Somo code was a life for a life, and since Nalasu alone remained alive of his family, it was well known throughout the tribe that the Annos would never be content until they had taken the blind man’s life.

But Nalasu had been famous as a great fighter, as well as having been the progenitor of three such warlike sons.  Twice had the Annos sought to collect, the first time while Nalasu still retained his eyesight.  Nalasu had discovered their trap, circled about it, and in the rear encountered and slain Anno himself, the father, thus doubling the blood-debt.

Then had come his accident.  While refilling many-times used Snider cartridges, an explosion of black powder put out both his eyes.  Immediately thereafter, while he sat nursing his wounds, the Annos had descended upon him—­just what he had expected.  And for which he had made due preparation.  That night two uncles and another brother stepped on poisoned thorns and died horribly.  Thus the sum of lives owing the Annos had increased to five, with only a blind man from whom to collect.

Thenceforth the Annos had feared the thorns too greatly to dare again, although ever their vindictiveness smouldered and they lived in hope of the day when Nalasu’s head should adorn their ridgepole.  In the meantime the state of affairs was not that of a truce but of a stalemate.  The old man could not proceed against them, and they were afraid to proceed against him.  Nor did the day come until after Jerry’s adoption, when one of the Annos made an invention the like of which had never been known in all Malaita.
