When it was secured, she slowly let it down, until it reached Rollo's hand, which was held up from below, ready to receive it. Mary then held the thread steady above, at a little distance out from the window, while Rollo took the stone along the side of the house, three or four feet from the place where it would naturally hang. He then let it go, and it swung back very slowly. "O, how slow!" said Rollo. "Yes," said Mary, "it is very slow, indeed." "I wish you had gone up to the garret window," said Rollo. "O, this will do very well," said Mary. Rollo determined to see how many he could count while the stone made one oscillation to and fro. He counted sixteen. Mary then said she was tired of experimenting, and so she should not come down again. She, however, asked Rollo to set the pendulum swinging, and that then she would draw the thread in, and he could see that it would go faster and faster, the farther she drew it up, for that would make the string grow shorter and shorter. Rollo did so; and this was the end of the experiments on oscillations.

The frontispiece however relates to a different chapter (Pruning) and so the footnote has been removed} Page 149: and the small end{original had and} of the magnet would draw the point of the needle
