proper methods, referring to the very great numbers of 

 young fish destroyed wantonly and unnecessarily by the 

 methods of fishing practiced by the Chinese. 



CULTIVATION OF CARP IN CALIFORNIA. 



Mr. J. A. Poppe, of Sonoma, California, calls the attention 

 of the farmers of the United States to the subject of carp rais- 

 ing, in which he refers to his own experiences in the intro- 

 duction of this fish into the country. In August, 1872, he 

 arrived at Sonoma from Germany with five small carp, six 

 inches long, all in very poor condition, one dying as it was 

 placed in the Avater. In the following May he states that 

 the fish had grown to be sixteen inches long, and had pro- 

 duced over three thousand young fish. He now has a very 

 large stock, and all that he can send to market sell readily 

 at one dollar per pound as an article of food, and he has no 

 diflSculty in disposing of all the living fish he is willing to 

 spare at five dollars each. He remarks that when well fed 

 the fish will grow one inch per week for the first two or three 

 months, after which the growth in length is slower, but they 

 increase in weight very rapidly. 



CAPTURING EELS IN COCHIN CHINA. 



An ingenious device is practiced in Cochin China for the 

 capture of eels, which consists in cutting pieces of bamboo 

 as thick as the arm into sections of about three or four feet 

 in len2!:th,the divisions of the interior beino: broken out, with 

 the exception of the one at the end, which forms the bottom 

 of the snare. At the entrance is placed a slight grating of 

 bamboo, and some bait, either of fish or earth-worms, is in- 

 troduced into the interior. The bamboo is then laid at a 

 slight depth in the mud, and the eels enter the hollow tube, 

 in which they can scarcely move, and can not turn them- 

 selves, and are consequently taken captive. The bamboo 

 is taken up every morning, and the eel, which holds on very 

 firmly to the interior, is pulled out by means of a strong 

 hook. 10 B, June, 1875, 290.
