News reaches us that Lafayette 

 are being taken in numbers this 

 Summer, as many as <S0 or !*() of 

 these excellent little pan-lish being 

 caught on hook and line by one person 

 in a morning at Rqckaway. There 

 is a wide-spread belief among fisher- 

 men that this species is abundant 

 near New \ ork every seventh year, 

 but this is not borne out by the records 

 that are available. From "Forest 

 and Stream," we learn that they were 

 abundant in 19U2, and again in 19(J(S.

 Review for September we learn that 

 Amhlyopsis, the blind-tish of Ohio 

 Valley Caves, carries its eggs in its 

 gill cavity, and the young remain 

 there until the yolk is absorbed. The

A Unique Conservatory 



Our Co\er design illustrates a 

 section of the very artistically arrang- 

 ed conservatory of Mr. F. B. Johon- 

 not of Brooklyn. Additional illus- 

 trations appeared in a recent number 

 of TAB. In its arrangement, utility 

 and beauty have been combined in a 

 most satisfactory manner, both Gold 

 and Tropical fish being housed. 

 Further illustrations and a story of 

 this conservatory will appear in an

 flowing water will take the fish with

 the tube out of the water and empty 

 it into a suitable receptacle. 



Among the remedies used by 

 aquarists for the cure of the various 

 ills of fishes are rocksalt, epsom 

 and glauber salts, phenol sodique, 

 peroxide, permanganate of potas- 

 sium, glyco thymoline, castor oil, 

 bichlorate of mercury, salicylate of 

 soda and ammonia.
