“Why, they only bury up wood, as I did my log, lightly, so that enough air can get in, until it is burnt through; and then they cover it up tight, so that no air can get in, and so it goes out; and when it is all cold, they open it, and find the heap is all black coals.”
“How big a heap do they make?” asked Rollo.
“O, they make a very large heap, sometimes,” said Jonas; “as big as this.” So Jonas rose from his seat, and marked out a circle in the yard with a stick, which he had in his hand, in order to show Rollo how large a heap they make, when they pile up wood for a charcoal bed.
“And how high do they make it?” asked Rollo.
“As high as that” said Jonas; and he reached his stick up in the air as high as he could, to show Rollo how high the heap was.
“That must take a great deal of wood,” said Rollo.
“Yes,” said Jonas, “and when it is turned into charcoal, they get a great many loads of it.”
“How do they get ashes enough to cover it up?” asked Rollo.
“O, they don’t cover it with ashes,” said Jonas; “they cover it with turf.”
“With turf?” repeated Rollo.
