ner." Comments by the president of the 

 Park Board, Mr. George Weems Wil- 

 liams, and prominent aquarists of the 

 city, indicate that the project is not likely 

 to be dropped. The movement is a fur- 

 ther indication of the growing recogni- 

 tion of the value of an aquarium as an 

 educational factor. 



Potatoes Ala Daphne 



Brannf oxit is a little wooded isle in 

 the Housatonic River, Connecticut, a 

 region rich in Indian lore. There the 

 Reverend Arthur Boxer Creichton main- 

 tains his summer camp, and with him 

 recently, as guests, were Mr. and Mrs. 

 G. Frederick Wood and Mrs. W. A. 

 Poyser. They discovered that the river 

 water used for camp purposes was alive 

 with Daphne. This luscious crustacean, 

 beloved of our aquarium fishes, seemed 

 to impart flavor to the camp cookery and 

 /est to the appetite — perhaps it was the 

 h fluer.ee of the forest primeval. Like 

 loyal fish lovers no attempt was made to 

 strain the v^ater. With the constantly 

 increasing cost of high living, why not 

 Daphne salad instead of lobster? 



Where is the organ of hearing in fish 

 located? — B. J. E. Fach scale of the 

 lateral lines of a fish is perforated by a 

 tube leading to a duct connected with a 

 sac in the head, their function being the 

 secretion of mucus, which covers the 

 body to lessen the friction of scales and 

 water, and make it impervious. This 

 mucilaginous system is also provided 

 with nerves and is the seat of a peculiar 

 sense which corresponds to the organs 

 of touch and hearing. — From ''Goldfish 

 E reeds," by H. T. Wolf. 



The name polyp (Greek polupous, 

 many-footed) was originally given to the 

 octopus in allusion to its many foot-like 

 tentacles, and thence extended to the 

 fresh water Hydra. 



The extremely thin surface layer of 

 water in contact with the air acquires 

 physical properties comparable to those 

 of an extremely fine membrane. 



Goldfish fanciers who have bred the 

 shunkunkin have found that a very few 

 equal the parents in coloration. The ma- 

 jority of the young are plain colored, 

 some are scaled, and a few of both will 

 have double, tails. 



Large Jap and red snails should be 

 watched closely and removed from the 

 tank when they die, otherwise serious 

 pollution of the water may result. 



Aquarists are divided on the use of 

 soil for aquarium plants. Sagittaria and 

 Anacharis seem to grow just as well in 

 sand or gravel. Lender these conditions 

 it is said that the roots serve mainly to 

 anchor the plants and consume the 

 humus, the leaves assuming a more at- 

 tractive bright green color. 



The excrement of a goldfish, when the 

 fish is in good condition, usually appends 

 for some time as a long worm-like thread. 

 Its texture and freedom from mucous 

 and gas bubbles rather than color indi- 

 cates health. The color will depend 

 upon the food, few other than daphne 

 cause black-brown excreta. 



The Bubble-shell Snail is Physa heter- Some men's religion is all located in 

 astropha, a common native species of their Sunday suit of clothes, and hung 

 ponds and slow streams. up in the closet during the week.
