of Washington, D. C. recently gave a 

 lecture on "The Balanced Aquarium or 

 House Pond," before the teachers and 

 pupils of the Seaton School. He illus- 

 trated his talk with an aquarium which 

 was complete, and with another which he 

 equipped before his audience.

It is to be regretted that political influ- 

 ence in St. Louis is being exerted in op- 

 position to the establishment of a public 

 aquarium. The big business house of 

 Messrs. Salomon and Schuchat, however, 

 announces that it will equip and main- 

 tain in its store an extensive permanent 

 exhibition that will cost some thousands 

 of dollars to maintain. Let us hope that 

 the generosity of this firm will serve to 

 impress upon the politicians that the peo- 

 ple cannot always be led, and that the 

 time is approaching when an adequate 

 public and permanent exhibtion will be 

 demanded in no uncertain terms. In edu- 

 cational value a public and permanent 

 exhibition of aquatic life follows close 

 after the school house.

Shells of Land and Water. By 

 Frank Collins, of the Chicago Academy 

 of Natural Science. W T hat is the life- 

 history of a snail? From this interesting 

 volume you will learn how they live, 

 where they live, and how to collect them. 

 Written in a popular style, the chapters 

 take one on numerous outings with a 

 college professor and his class. Eight 

 full-page plates, showing 82 species in 

 their natural colors, and numerous half- 

 tone and line engravings, adequately sup- 

 plement the text. Octavo, cloth binding. 



The crayfish is said to live 20 years; 

 the sea anemone 50 years ; the pike and 

 carp 100 years.

example of protective coloration, for its 

 hues vary with the time and the bright- 

 ness of the day. In the sunshine of the 

 early morning the frog is a bright blue- 

 green ; later, as the day advances, its 

 color becomes a deeper and darker green, 

 and toward night almost black. 



It is not till the sun has set that the 

 flying frog begins to shake off its torpor. 

 Then it rouses to the business of the day 

 — or of the night — and sallies forth on its 

 hunt for insects. It shows a great pref- 

 erence for large butterflies, and, aided by 

 its remarkable leaping powers, is very 

 successful in capturing them. 



The strange little animals do not con- 

 fine their activities to the earth and trees, 

 but are equally at home in the water. 

 There the webs that serve them as wings 

 on land become useful as oars.
