this beginning of which the engineer spoke was the construction of an apparatus which would serve to transform the natural substances. The part which heat plays in these transformations is known. Now fuel, wood or coal, was ready for immediate use, an oven must be built to use it.
"What is this oven for?" asked Pencroft.
"To make the pottery which we need," replied Harding.
"And of what shall we make the oven?"
"With bricks."
"And the bricks?"
"With clay. Let us start, my friends. To save trouble, we will establish our manufactory at the place of production. Neb will bring provisions, and there will be no lack of fire to cook the food."
"No," replied the reporter; "but if there is a lack of food, for want of instruments for the chase?"

"Well?" asked Cyrus Harding.

"Yes, a knife, a sharp blade"—said the engineer, as if he was speaking to himself.
At this moment his eyes fell upon Top, who was running about on the shore. Suddenly Harding's face became animated. "Top, here?" said he.
The dog came at his master's call. The latter took Top's head between his hands, and unfastening the collar which the animal wore round his neck, he broke it in two, saying:
"There are two knives, Pencroft!"
Two hurrahs from the sailor was the reply. Top's collar was made of a thin piece of tempered steel. They had only to sharpen it on a piece of sandstone, then to raise the edge on a finer stone. Now sandstone was abundant on the beach; and two hours after, the stock of tools in the colony consisted of two sharp blades, which were easily fixed in solid handles.
The production of these their first tools was hailed as a triumph. It was indeed a valuable result of their labor, and a very opportune one. They set out. Cyrus Harding proposed that they should return to the western shore of the lake, where the day before he had noticed the clayey
