PREFACE TO HALCYON HOUSE EDITION 



Interest in the aquarium hobby has expanded so tremendously in the 

 past few years that it might now be termed one of our national pleasures. 



Since originally published, under the title "Goldfish Varieties and 

 Tropical Aquarium Fishes," this book has gone through 15 editions, each 

 one revised, improved, and larger than its predecessor. It is everywhere 

 recognized as the world's standard book on the subject. While the price 

 has always been $4.00, we hoped to find a method of manufacture and 

 marketing that would place the work within the reach of everyone. 

 Through our arrangements with Halcyon House, this is now happily 

 accomplished. 



The present edition not only contains everything that was in former 

 printings, but there are several added color plates taken from our new 

 $5.00 book ("Exotic Aquarium Fishes"), devoted exclusively to tropicals. 



Likewise there are some plates taken from our monthly magazine, 

 "The Aquarium" ($2.00 per year). 



We are always glad to write aquarists having special problems (if 

 stamped, self-addressed envelope is enclosed), but as this book answers 

 all the questions received over a period of many years, we request that 

 readers make sure the answer is not here before writing us. 



We do not deal in aquarium fishes or supplies.
