off from the shore, but, when they saw the boat approaching, fled again.  The Admiral landed and found two empty houses containing nets and hooks and fishing-lines, and one of the strange silent dogs, such as they had encountered on the other island—­dogs that pricked their ears and wagged their tails, but that never barked.  The Admiral, in spite of his greed for gold and his anxiety to “free” the people of the island, was now acting much more discreetly, and with the genuine good sense which he always possessed and which was only sometimes obscured.  He would not allow anything in the empty houses to be disturbed or taken away, and whenever he saw the natives he tried to show them that he intended to do them no harm, and to win their good will by making them presents of beads and toys for which he would take no return.  As he went on up the river the scenery became more and more enchanting, so that he felt quite unhappy at not being able to express all the wonders and beauties that he saw.  In the pure air and under the serene blue of the sky those matchless hues of blossom and foliage threw a rainbow-coloured garment on either bank of the river; the flamingoes, the parrots and woodpeckers and humming-birds calling to one another and flying among the tree-tops, made the upper air also seem alive and shot with all the colours of the rainbow.  Humble Christopher, walking amid these gorgeous scenes, awed and solemnised by the strangeness and magnificence of nature around him, tries to identify something that he knows; and thinks, that amid all these strange chorusings of unknown birds, he hears the familiar note of a nightingale.  Amid all his raptures, however, the main chance is not forgotten; everything that he sees he translates into some terms of practical utility.  Just as on the voyage out every seaweed or fish or flying bird that he saw was hailed by him as a sign that land was near, so amid the beauty of this virgin world everything that he sees is taken to indicate either that he is close upon the track of the gold, or that he must be in Cipango, or that the natives will be easy to convert to Christianity.  In the fragrance of the woods of Cuba, Columbus thought that he smelled Oriental spices, which Marco Polo had described as abounding in Cipango; when he walked by the shore and saw the shells of pearl oysters, he believed the island to be loaded with pearls and precious stones; when he saw a scrap of tinsel or bright metal adorning a native, he argued that there was a gold mine close at hand.  And so he went on in an increasing whirl of bewildering enchantment from anchorage to anchorage and from island to island, always being led on by that yellow will o’-the-wisp, gold, and always believing that the wealth of the Orient would be his on the morrow.  As he coasted along towards the west he entered the river which he called Rio de Mares.  He found a large village here full of palm-branch houses furnished with chairs and hammocks and adorned with wooden masks and statues; but in spite of his gentleness and offer of gifts the inhabitants all fled to the mountains, while he and his men walked curiously through the deserted houses.
