YOU CAN JUDGE 
an aquarist by his library. The pro- 
gressive aims to secure all the avail- 
able literature of the subject. His 
slogan is “read, mark and learn.” The 
elementary books are stepping stones 
to the more technical works. Ad- 
vanced treatises assume that the stu- 
dent is grounded in the subject; the 
elementary takes nothing for granted. 
Both are necessary; one an introduc- 
tion to the other, and to success and 
pleasure. For your library we suggest 
the following: 
Keystone Volumes 
AQUALIC Winky hevrecosnized 
standard in periodical aquarium lit- 
erature. A volume averages 165 pages, 
and as many or more illustrations— 
a picture whenever it is needed. Each 
year brings forth papers on the funda- 
mentals of aquarium management and 
the breeding of goldfish, two ever pop- 
ular phases. Month after month ap- 
pear articles on the tropical fishes; he 
who reads may breed them; nowhere 
else in this detailed information avail- 
able. A volume is in itself a “com- 
plete aquarium book.” Volume I has 
long since been out of print and now 
commands a premium; Volume II 
(few copies remain), $2.25, postpaid; 
Volume III (ready in September), 
$2.25, postpaid. 
AQUATIC MICROSCOPY. By Dr. 
Alfred C. Stokes. This book, whether 
or not you possess a microscope, will 
immeasurably add to your knowledge 
of the minute organisms that play 
such an important part in the econ- 
omy of the early life of your fishes. 
If you have a ‘scope it will tell you 
how to use it to the best advantage. 
It should be studied by every aquar- 
ist—it forms the stepping stone to 
Ward and Whipple’s “Fresh Water 
Biology.” 324 pages, with 198 illus- 
trations. $2.25, plus postage on two 
pounds. 
THE HOME AQUARIUM. By Eu- 
gene Smith. A splendid book by a 
man who was a scientist as well as an 
aquarist, which bespeaks the accur- 
acy of the work. The construction, 
principles and management of the 
aquarium, the proper plants, hardy 
fishes and other animals, methods of 
collecting specimens and other details 
are well covered. Particular attention 
is given to desirable wild fishes. 213 
pages, with 137 illustrations. $1.50, 
plus postage on two pounds.
