eleven o'clock
Towards night we carried our tools to the place where we expected to dig for the gold , and starting before sundown rode our animals to the river and watered them , so that they would not break away from their stakes during the night for the purpose of slaking their thirst . Then we waited impatiently for darkness for the purpose of once more changing our camping ground , and this time we left nothing behind . Our quarters were fixed at a short distance from the island , so that when the moon was up we could keep our eyes on the horses , yet not be seen on the main land . At eleven o'clock the first rays of the full moon became visible from behind Mount Tarrengower . The night was awful quiet , and not a living thing had approached us , and not a sound had we heard , except an occasional bleat of a lamb , off towards the stock-house on our left . `` Let us be moving for the island , '' Mr. Brown said , almost in a whisper , for the solemnity of the scene was bringing back all his superstitions and fears . I readily consented , and , lighting our pipes , we walked slowly towards the peninsula , crossed it , and then waited calmly for the shadow which the mountain was to throw upon the spot of earth where the robber 's treasure was buried .
