n Jack Frost you may
laugh at,--but as to Old Zero, you had better beware of him."

Rollo laughed a good deal at Jonas's account of the three Northmen, and
Jonas told him that they sometimes made some splendid curiosities, which
would be beautiful for a shelf in his museum, if they would only keep.

"What are the curiosities?" said Rollo.

"O, all kinds of stars, and spangles, and snow-flakes, of a great many
beautiful forms,--and icicles, and frost work. But they will not keep
very long, unless you make a cabinet expressly for them."

"_I_ can't make a cabinet," said Rollo.

"O, yes, you can,--a frost-cabinet," said Jonas.

"How?" asked Rollo.

"Why, you must go down near the brook, in the middle of the winter, and
make a little room of snow. Then you must get a large piece of thin,
clear ice from a still place in the brook, and fix it in for a window.
You must also get some sheets of white ice, or snow crust, for shelves,
and put your frost curiosities upon them. If you make it in a cold
place, they will keep for some time."

"I _will_ make a frost museum," said Rollo. "I mean to go down to-day
and look out a place."

"Yes," said Jonas, "and you can keep it a secret until it is done, and
then take your father and mother down to see it, and surprise them."

"Yes," said Rollo, clapping his hands, "so I will."

ROLLO BOOKS.

BY JACOB ABBOTT.

_Rollo at Work_, _Rollo at School_,
_Rollo at Play_, _Rollo's Vacation_,
_Rollo Learning to Read_, _Rollo Learning to Talk_.

BOUND IN UNIFORM STYLE.

The publishers request the attention of the friends of the young to this
popular series of books, which have been pronounced, by competent and
judicious persons, the best works for children published, not even
excepting the best English writers. Mr. Abbott's style is peculiarly
interesting to children, being natural and simple, and portraying the
trials and temptations of childhood, just as they occur in every day
life, and giving them clear and distinct ideas of the right and wrong in
their actions.

_From the Christian Examiner._

As a whole, they make the most important series of juvenile books that
have appeared, to our knowledge, since Miss Edgeworth. They are very
unlike those, and yet they resemble them in some prominent features;
especially in making it their chief object to be _pleasing_, and
