Millimetres in a metre
No, replied Jonas, it is not the smoke.They make an enormous bag of silk, and millimetres in a metre fill it with this light air, which they make in barrels and then, when the bag is filled, it floats away above their heads, and pulls hard upon the fastening.Now, do you remember what your father told you, the other day, about the effect of heat upon air? It makes it light, said Rollo.Their mother, finding that the boys did not wish much to hear any conversation about the air, said nothing more about it just then, and Rollo and Nathan got some books, and began to read but somehow or other, they did not find the books very interesting, and Rollo, millimetres in a metre after reading a little while, put down his book, and went to the window, saying that he wished it would stop raining.Now, wherever there is heat, continued his mother, the air is made lighter, and the cool and heavy air around presses in under it, and buoys it up.Now, continued his mother, you see that a great deal of air comes in, and if you millimetres in a metre look up chimney, you will see that there is scarcely room for so much to go up there and yet just as much must go out as comes in.There was air in the stump, said Rollo.QUESTIONS millimetres in a metre.I must supply the want, by my energy and decision.Yes, millimetres in a metre said his mother.What are they for? said Rollo.Yes, millimetres in a metre I believe they have been made as big, said she.Rollo did so and he found that it was carried in, proving, as their father had showed them before, that the heavy, cold air, pressing into the room, crowded the warm, light air up the chimney.No, replied millimetres in a metre Jonas it is all close and solid around the air cannot get in.
