bird being mottled grey and brown with dark beak and legs, 
whilst when the full plumage is attained the bird shines forth 
with snowy head, throat, and breast, wings almost black, and 
orange beak ; between these extremes may be seen all varieties, 
one merging into the other, in such a group as that depicted 
above.

REVIEWS AND EXCHANGES. 
The Insect Folk. By Margaret Warner Morley. Illustrated by the Author. 
Ginn and Co. Price 2S. 
There are very few pages in this attractive children’s book which we do not 
like. One of them, at the beginning, bears in large black type the words 
Odonata Ephemerida Plecoptera Thysanura. These and other equally out of 
place technicalities are explained in a Glossary, which might well have been ren- 
dered less necessary. But everything of this kind can apparently be readily 
ignored, and we have nothing but praise for the charmingly told and illustrated 
life-histories of the three dozen or so of insect types. The whole swarms of 
dragon-flies, May-flies, and grasshoppers crossing the pages are delightful ; and 
though some of the types selected are mainly American many an English reader 
of Transatlantic literature will be glad to learn more of the Katydid. The 
Lepidoptera and Hymenoptera are omitted — for treatment, we hope, in a com- 
panion volume — and we could willingly have dispensed with the two or three 
pages devoted to some members of “ The Great Bug Family,” though country 
children will be pleased to read about the Water Boatmen and the Aphis. 
If somewhat too directly didactic, there is much that is refreshingly original 
in the whole treatment of the subject. 
Ways of the Six-Footed. By Anna Botsford Comstock. Ginn and Co. Price 2s. 
This volume is intended forsome what older readers than the one just noticed. 
It comprises ten stories of insect-life “ written with the definite purpose of illus- 
lating the great primal truth that wherever there is life there are problems con- 
tfronting it ; and that the way of solving these problems has been the way to 
success in the evolution of a species.” The musical organs of various insects, 
protective resemblance, the perfect socialism of bees, ants and termites, and the 
leafy tents constructed by the miner are among the topics thoughtfully described 
from personal observation, with the inspiration of a poetical naturalist such as 
Fabre, rather than the parabolical morality of Mrs. Gatty, or the mysticism of a 
Maeterlinck. 
Geological Rambles in East Yorkshire. By Thomas Sheppard, F.G.S. Illus- 
trated from Photographs, with a Coloured Geological Map of the District. 
A. Brown and Sons. Price 7s. 6d. 
Yorkshire can boast of a series of great geologists, from Adam Sedgwick and 
John Phillips downward, and so varied are the formations exposed along its coast- 
line that we are not surprised at the appearance of this volume of geological 
rambles dealing exclusively with one of its Ridings. The book is thoroughly 
practical, wasting no space in fine writing, but carefully describing the country 
bit by bit, from the Humber to Scarborough, supplementing some fifty admirable 
photographs with outline diagrams and mentioning many of the more important 
fossils. Much of the matter has previously appeared in the Leeds Mercury 
Supplements during the last three years. Might we suggest, for a second edition, 
the addition of a list of published maps and sections and at least a select biblio- 
graphy of books and papers on the district?
