"He found the trees all ready to his hand. Come, and you shall see our excellent guide at work."
More and more amazed at what I heard and saw, I followed my uncle like one in a dream.
After a walk of about a quarter of an hour, I saw Hans at work on the other side of the promontory which formed our natural port. A few minutes more and I was beside him. To my great surprise, on the sandy shore lay a half-finished raft. It was made from beams of a very peculiar wood, and a great number of limbs, joints, boughs, and pieces lay about, sufficient to have constructed a fleet of ships and boats.
I turned to my uncle, silent with astonishment and awe.
"Where did all this wood come from?" I cried; "what wood is it?"
"Well, there is pinewood, fir, and the palms of the northern regions, mineralized by the action of the sea," he replied, sententiously.
"Can it be possible?"
"Yes," said the learned Professor, "what you see is called fossil wood."
"But then," cried I, after reflecting for a moment, "like the lignites, it must be as hard and as heavy as iron, and therefore will certainly not float."
"Sometimes that is the case. Many of these woods have become true anthracites, but others again, like those you see before you, have only undergone one phase of fossil transformation. But there is no proof like demonstration," added my uncle, picking one or two of these precious waifs and casting them into the sea.
