On both sides were visible, on seven rows of scales, the remains of the 

 excn^scences of the spawning season. In the same lake among smelts 

 there was taken, A])ril C, a second specimen of "blaufelchen," which 

 was identified by Professor Benecke, and which measured 32 centimeters 

 in length, 7 centimeters in height, 3.5 centimeters in thickness, and 

 weighed 284 grams. 



Mr. Ohlert, of Somersin, in West Prussia, reports that Mr. Caspar! 

 took GO blanfelchen with the coarse net in winter in the Suramin Lake, 

 where formerly only small maraenae occurred ; three years ago fry of 

 Madu marcena and blanfelchen were introduced. Professor Benecke 

 identified a spent male 22 centimeters long, 6.5 high, 2.7 thick, and 

 weighing 220 grams. The same fish was sent to Dr. Gemmiger, of 

 Munich, and by this gentleman also was recognized as a blanfelchen. 



(Five other instances are given of successful breeding of the white- 

 fish in German lakes.) 



CARP CULTURE. 



Sprottau. — A few years since, two-year old carp were placed in the 

 Sprottau, and fine large specimens were taken this summer. 



Potfidam, July 15, 1883. — The planting of carp in the waters of Pots- 

 dam district has been attended by evident success. 



Berneuchen {Max von dem Borne). — Since the lakes of Berneuchen and 

 the Mietzel have been regnlarly stocked with yearling carp, these waters 

 have been wonderfully productive of beautiful, great table carp. The 

 same is true of the Botzen Lake of Dolzig, but there it was not possible 

 to catch great numbers of carp until, last winter, the net was enlarged 

 so that the whole lake could be swept at a single draught under the ice. 



The success was complete. The net contained all the fish it could 

 hold, mainly carp. The largest of these, about 4,000 pounds weight, 

 were taken out, and the greater part turned back to allow the carp to 

 grow larger. 



EEL CULTURE. 



Years ago Director Haack,' of Hiiningen, got a great quantity of eel 

 fry from French rivers, and in the spring sent them by mail to all parts 

 of Germany. From the planting of these fry in the lakes and rivers 

 very good results have followed, in several cases within my own knowl- 

 edge. This fall a spring pool, unconnected with any other water, and 

 without outlet, was fished. Four eels were taken; they' were one and 

 three-fourths years old, and the poorest weighed one and one-quarter 

 pounds. In the spring of 1882 a few specimens of eel fry had been 

 ])laced here to observe the growth. 



On the profitableness of eel culture, Mr. !N^ehrkorn-Eiddagshausen 

 (Braunschweig) says that a short time ago he had a small pond fished 

 out that he had a few years before stocked with 500 young eels, and 

 hat about 250 young eels were found, ranging from one-fourths to one 

 kilogram (.55 to 2.20 pounds), some specimens weighing even one and one-
