The next day Dick was sitting under the shade of the artu. He had the box of fishhooks beside him, and he was bending a line on to one of them. There had originally been a couple of dozen hooks, large and small, in the box; there remained now only six--four small and two large ones. It was a large one he was fixing to the line, for he intended going on the morrow to the old place to fetch some bananas, and on the way to try for a fish in the deeper parts of the lagoon.
It was late afternoon, and the heat had gone out of the day. Emmeline, seated on the grass opposite to him, was holding the end of the line, whilst he got the kinks out of it, when suddenly she raised her head.
There was not a breath of wind; the hush of the far-distant surf came through the blue weather--the only audible sound except, now and then, a movement and flutter from the bird perched in the branches of the artu. All at once another sound mixed itself with the voice of the surf--a faint, throbbing sound, like the beating of a distant drum.
"Listen!" said Emmeline.
Dick paused for a moment in his work. All the sounds of the island were familiar: this was something quite strange.
Faint and far away, now rapid, now slow; coming from where, who could say? Sometimes it seemed to come from the sea, sometimes, if the fancy of the listener turned that way, from the woods. As they listened, a sigh came from overhead; the evening breeze had risen and was moving in the leaves of the artu tree. Just as you might wipe a picture off a slate, the breeze banished the sound. Dick went on with his work.
Next morning early he embarked in the dinghy. He took the hook and line with him, and some raw fish for bait. Emmeline helped him to push off, and stood on the bank waving her hand as he rounded the little cape covered with wild cocoa-nut.
These expeditions of Dick's were one of her sorrows. To be left alone was frightful; yet she never complained. She was living in a paradise, but something told her that behind all that sun, all that splendour of blue sea and sky, behind the flowers and the leaves, behind all that specious and simpering appearance of happiness in nature, lurked a frown, and the dragon of mischance.
Dick rowed for about a mile, then he shipped his sculls, and let the dinghy float. The water here was very deep; so deep that, despite its clearness, the bottom was invisible; the sunlight over the reef struck through it diagonally, filling it with sparkles.
