The boys quickly did so, and it was not long before those that had not gone off and dug nests in the snow for themselves, were closely cuddled together on the comfortable robes.
In the meantime supper was being prepared by others. Meat and fish in generous quantities were cooked in the kettles. Bread and flat cakes, well supplied with grease or fat, were being thawed out, and a large quantity of good black tea was prepared.
A large deerskin robe was carefully spread out before the fire, and over this a plain tablecloth was laid. Then the dishes, which were all indestructible, were placed in position, and the fat meat, strong tea, and hot rolls or buns were vigorously attacked by Mr Ross and the boys. While they were thus enjoying their meal the rest of the party, not far off, were similarly engaged.
There were several things about this camping out in the woods that much surprised the boys. One was that the numerous sparks from the fire had such long fiery tails. Another was that the frost so quickly froze up the large pieces of meat, that often had to be thawed out two or three times at each meal. Another was that the ice often formed on their cups of tea, which had been taken boiling hot out of the kettle only a few minutes before. Then they were startled by sharp reports, like pistol or musket shots, that they kept hearing from places in the dark forest all around them, as though some lurking savages were taking snap shots at them. Two especially were so near, and so real, that Sam jumped up so suddenly that he spilled his tea over the tablecloth.
“Faith, indeed,” he exclaimed, “I don’t want to be potted out here by any wild huntsmen, or Northern desperado, or red Indian.”
The other boys were also much startled, but Mr Ross quieted their fears by telling them that these sounds were caused by the bursting in the trees, as the result of the freezing sap. Water in freezing always expands, and as there is sufficient sap in some trees, when it freezes, it bursts them. It must expand, and tremendous is its power, as even the burst rocks show.
“It is a good thing that the ice remains on the top of the water,” said Frank. “As it freezes it expands, and thus, being lighter than the water, it comes to the top.”
“What a mess we would be in,” said Sam, “if as the ice froze in chunks it sank to the bottom and kept at it all winter. Sure then, before spring, in such a land as this, the lakes and rivers would all be one solid mass of ice, and then what would become of the fish and us?”
“A sensible remark, Sam, and characteristically put,” said Mr Ross. “If the ice were heavier than the water, and continued sinking, the colder regions would continually be encroaching on the warmer, to such a degree that in time the earth’s habitable portions would be very much diminished.”
“Why is it,” said Alec, “that the milk which we are carrying in chunks, wrapped up in paper bags, when put into our cups of tea, does not melt as soon as do the lumps of white sugar of the same size?”
