coral in pieces, and cast it up in the form of sand. Here sea-birds had alighted, little pieces of sea-weed and stray bits of wood had been washed up, seeds of plants had been carried by the wind, and a few lovely blades of bright green had already sprung up, which, when they died, would increase the size and fertility of these emeralds of Ocean. At other places these islets had grown apace, and were shaded by one or two cocoa-nut trees, which grew, literally, in the sand, and were constantly washed by the ocean spray; yet, as I have before remarked, their fruit was most refreshing and sweet to our taste.
Again at this time Jack and I pondered the formation of the large coral islands. We could now understand how the low ones were formed, but the larger islands cost us much consideration, yet we could arrive at no certain conclusion on the subject.
Having satisfied our curiosity and enjoyed ourselves during the whole day, in our little boat, we returned, somewhat wearied, and, withal, rather hungry, to our bower.
"Now," said Jack, "as our boat answers so well, we will get a mast and sail made immediately."
"So we will," cried Peterkin, as we all assisted to drag the boat above high-water mark; "we'll light our candle and set about it this very night. Hurrah, my boys, pull away!"
As we dragged our boat, we observed that she grated heavily on her keel; and, as the sands were in this place mingled with broken coral rocks, we saw portions of the wood being scraped off.
"Hallo!" cried Jack, on seeing this. "That won't do. Our keel will be worn off in no time at this rate."
