Towards noon about three miles had been accomplished , and a halt was made for rest . Neither Negoro nor Harris had been seen , nor had Dingo reappeared . The encampment for the midday refreshment was made under the shelter of a clump of bamboos , which effectually concealed them all . Few words were spoken during the meal .
