and it is soon able to eat the tiniest 

 daphne, and from this time on it should 

 never be without this succulent morsel. 

 However, before the daphne is used some 

 breeders feed the yolk of a thirty-minute 

 boiled egg, mixing it with a little water 

 and straining it through fine lawn or 

 cheese-cloth. It must be used cautiously 

 lest the water be polluted. As the fish 

 grow they may be occasionally fed a little 

 boiled oatmeal, to which a little shrimp 

 or shredded codfish has been added ; mos- 

 quita larva if available will be equally 

 as good as daphne. 



The growth of the fish will not be de- 

 pendent solely upon the foods, but 



Myriophyllum 



equally upon the water space. The more 

 room they are given the quicker and 

 more vigorously they will grow. To this 

 end they should be sorted frequently, 

 according to size and individual perfec- 

 tion, and the least desirable ones dis- 

 carded. Those who breed in great num- 

 bers use oblong tanks of wood, but the 

 beginner will do well to get a battery of 

 ordinary wooden wash tubs of the larg- 

 est size, that hold about twenty gal- 

 lons. These may be placed in a row 

 and supplied with water from a pipe 

 having a pet cock for each tub. A length 

 of small rubber tubing should lead from 

 each cock to a tub, and a mere trickle of 

 water allow to run at all times. If it is 

 not possible to run the water constantly, 

 then at least some new water should be 

 added to each tub daily. 



When the youngsters have reached a 

 length of an inch not more than twenty 

 should be in a tub; half this number 



when two inches long — body length. Any 

 attempt to crowd will surely reduce the 

 rate of growth. 



Dr. Tarleton H. Bean died at his home 

 in Albany, N. Y., on December 28th, 

 after an illness of six weeks, following 

 an automobile accident. Dr. Bean be- 

 came connected with the United States 

 Fish Commission on January 1st, 1875, 

 and served for many years as scientific 

 assistant and ichthyologist. In 1892 he 

 became chief of the division of fish cul- 

 ture, which position he held until 1895, 

 when he resigned to become director of 

 the New York Aquarium. Since 1906 

 he has been fish culturist of the State of 



New York.

Mr. A. Volmer, of the Chicago Aqua- 

 rium Society, reports having eggs of the 

 four-horned snail, Ampullaria gigas, 

 hatch in eleven days. This is somewhat 

 shorter than the minimum period of in- 

 cubation usually mentioned. 



The comment of Mr. N. M. Grier, in 

 his "Aquarium Notes," January number, 

 that Anacharis has been known to cause 

 the death of snails, is most unusual, and 

 surely is based on faulty observation. I 

 raise large numbers of snails in cement 

 tanks and aquaria that are filled with this 

 plant, and with little or no loss. — Oscar 

 Leitholf. 



When a friend deals with a friend, let 

 the bargain be clear, that they may 

 continue friends to the end. 



The heart of a fish lies just under the 

 throat and is composed of but two cavi- 

 ties, whereas that of the higher animals 

 has four. 



Nature ever yields reward to him who 

 seeks, and loves her best. — Cornwall.
