Helen R. Albee. New York 1910.

A personal and very readable record, 
illustrated by photographs, of the author’s 
success in assembling within a limited 
area, the choice varieties of hardy shrubs, 
annuals, and perennials, so arranged as 
to give a succession of bloom of pure 
color in each bed. With a list giving 
manner of growth, height, time of bloom- 
ing, exact color, special requirements of 
soil and moisture, “easy ways” taught by 
experience, and many etceteras of vital im- 
portance. This book appears in the very 
attractive garb of the American Nature 
Series. The gold contrasts beautifully 
with the dark green. The illustrations are 
excellent and are well chosen and well ex- 
ecuted. It is a delightful book and is 
worthy of a considerable sale. There is an 
excellent garden diagram.

Prof. Kellogg’s book fills a gap in the lit- 
erature of natural history, or what may be 
called applied natural history. It covers the 
classification, propagation, and distribution 
of shell-fish. For those interested in 
oysters, clams or scallops, there is informa- 
tion on their structure, life-histories and 
habits. A chapter is devoted to shell-fish 
as collectors and carriers of disease organ- 
isms.

roots in touch with the life-giving earth beneath.
