down, and every thing replaced as it was before, he told
them that it was time for them to get up again. The punishment was not
very severe, it is true; but then, it was probably a pretty efficacious
one, in respect to its effect in impressing it upon Nathan's mind that
he must not touch things without leave, and upon Rollo's, that, when
Nathan is doing wrong, he must not set him right by violence.

In a short time after this, the things were all ready upon the table,
the chairs were placed around it, and Rollo went to call his father. He
found him writing a letter. As soon as he reached the end of a sentence,
he came out, and took his place at the table. Rollo's mother sat next to
him at the same side of the table, and Jonas and Dorothy in two chairs,
on the opposite side. Rollo then was placed at one end of the table,
and Nathan, in his high chair, at the other.

Just then, however, Rollo's mother observed that the table was wet a
little.

"Why, Rollo," said she, "how came the table wet?"

"Why, Nathan and I did it," said he.

"How?" said his mother.

"Why, we did it--eh--pulling. But Jonas has settled it all, mother."

"Ah! Jonas has settled it, has he? very well. Then we will all now
attend to the lecture."

MAGNETISM.

Rollo's father looked over the things which had been arranged upon the
table, for a moment, in silence, and then took up Jonas's magnet.

"This bar is what they call a magnet," said he; "but all the magnetism
is in the two ends."

"It is?" said Rollo; "and what is the reason of that?"

"You can see that it is so," said his father, without answering Rollo's
question, "in this way."

So he laid a small nail down upon the table, and then touched the middle
of the magnet to the nail. It was not attracted at all. Then he moved it
along a little, towards one end, and touched it again. Still it was not
attracted. Then he moved it along farther and farther; but the nail was
not attracted until he got to the end of the bar, and then the nail
hopped up and adhered to it quite strongly.

"How curious!" said Rollo.

His father then repeated the same experiment with the other half of the
bar, and found the result the same. The nail did not appear to be at all
attracted until he reached the end, and then it was lifted and held by
this end, just as it was by the other.

"So that, you see," said Rollo's father, "that the attractive power of
the magnet resides in the ends."

"Well, fathe
