MORE KNOWLEDGE FOR YOUNG READERS.

Ma. PRIICEVAL WESTELL IS an experienced writer upon natural history for young people, and his Nature's IVonderland (Pilgrim Press, 2s. (3d. net) is attractively arranged, being divided into months, for each of which he has some information upon the current botany, ornithology, entomology, &c. There is plenty of useful and pleasant discursive talk upon the various subjects. The book is illustrated by photographs of birds and other ohjects.—AN about Aircraft (Cassell and Co., Os.) may sound more alluring as well as ambitious just now when Nature seems to have to yield to man's latest and prominent ingenuity. Mr. Ralph Simmonds has enlarged and brought up to date his book, All about Airships, which was published in 1911. Invent tion and action have moved so quickly since then that them is plenty of now matter, both in the historical and scientific spheres in which the writer moves. British and many forms of foreign aircraft are dealt with, and the exposition gains by the good photographs and many diagrams. The narration of actual incidents in the war makes the instruction the more vivid.
