logical treatise, but as a
keen-eyed and thoroughly interesting observer would describe them. Such
a volume ought to be the companion of every intelligent boy and girl
during the summer.--_Christian Union_ (New York).

The book is deserving of praise for its eminently practical nature. The
hints to observers with which it opens, the appendix giving the
classification of birds by general family characteristics, by
localities, by colors, by song, the books of reference, and the index,
all combine to make the book extremely useful.--_The Academy_
(Syracuse).

_GREENE'S Coal and the Coal Mines._

In the vehicle of the author's terse, vigorous language, the reader is
then taken down into the subterranean passages, where he is almost made
to see the operations of mining the fuel, so vividly and picturesquely
is the information conveyed. Interesting and valuable statistics are
quoted, amusing incidents are related, entertaining descriptions and
wise suggestions are given and made, and, taken altogether, though
dealing largely with what is essentially dry in its nature, the book
makes good reading for the old as well as the young.--_The American_
(Philadelphia).

All kinds of science and scientific information is, at this day, brought
down from its high points to the lower and more even ground of the young
student's understanding. This book is a good example of that truth. The
exhaustive theme of coal and coal mining is made so concise and simple
that a child can thoroughly comprehend it. The author covers the ground
of study in a simple and interesting way, and furnishes illustrations to
make the words clearer.--_New York School Journal._

_MISS BAMFORD'S Up and Down the Brooks._

This is a book which it is a pleasure to read and a duty to praise. Miss
Bamford tells us of her rambles by the California brookside, and her
acquaintances made there; of their habits, their transformations, death
and burial, or happier release after a period of observation by the
captor.... On the whole, we do not know among recent books any more
likely to give pleasure to the nature-loving boy or girl, or more
calculated to stimulate the taste for healthy recreation and good
reading.--_The Nation_ (New York).

A charming book, full of most fascinating details in the lives of
little-known insects, and opening a rich field of study and interest,
accessible to every country child. It cannot be too highly recommended
to parents. The author h
