BULLETIN OF THE UNITED STATES FISH COMMISSION. 277 



October last those of the first lot were eighteeu or uiueteeu months old, 

 and we have already been able to impregnate artificially a few hundred 

 of their eggs, which have given us the same number of fry, and all arc 

 in tbe best condition. lam sure that if nt> disaster occurs we shall 

 prodnce the SaJmo quinnat and the Salmo fontinalis by thousands. 



" I have had this year more than G0,000 fry of common or river trout 

 and of lake trout [probably European], all coming from fish hatched in 

 my establishment. So there is reason to be pleased, and I would be 

 happy if I could show you the results of my work. I have sent to the 

 International Fisheries Exhibition at London a model of my hatching 

 shed, a plan of the establishment, and twenty bottles containing fish, 

 which were all, without a single exception, born in my establishment." 

 [i^wZZe^in, July, 1883, p. 428.] 



Brook trout. — Mr. Despr^s wrote from Nanteuil-en- Valine, among 

 other things: 



"The preceding parcels of eggs which have been sent me have given 

 good results. I have at the present time a hundred of i^almo fontinalis 

 about twenty months old, some of which are more than 20 centimeters 

 [about 8 inches] long. These are the ones which have received as extra 

 food horse-flesh chopped up fine. The others, which have had at their 

 disposal only the natural food which they were able to gather in a basin 

 of considerable size furnished with aquatic plants, show a less develop- 

 ment, but their health and vivacity aje all that could be desired. This 

 experiment in comparison has convinced me that it is necessary to give 

 them, when they are about seven or eight months old, some artificial 

 food in addition to that which thej' can find in the water, which is prob- 

 ably iusutficieut to allow them to attain a good development. 



"The specimens of last year are likewise in good condition. They 

 are as yet too small for me to state precisely their number. A rise of 

 water caused me to lose some of them, because of an unfortunate arrange- 

 ment of the basin which contains them. I have remedied this, and in 

 future will watch with care that a like accident may not happen again. 

 The escaped specimens i^robably have gone to grow up in the little 

 stream which flows near by the establishment." [Bulletin, February, 

 1884, p. 188.] 



Salmo carpio. — Mr. Kleiter, director of the fish-cultural establish- 

 ment at Munich, announced the sending of 2,000 embryonic eggs of 

 Salmo carpio, which he was directed to make to the Society of Acclimat- 

 ization on the part of the German Association of Fish-culture. At this, 

 Mr. Kaveret-Wattel recalled to mind that the Salmo carpio of Lake Garde 

 is an excellent species of trout, which never becomes very large, but 

 whose flesh is much like salmon and is of an exquisite flavor. One fish- 

 cultural establishment alone, on the shore of Lake Garde, is occupied 

 with multiplying this species, so interesting to propagate, and remark- 

 able, moreover, in this, that the spawning season is continued with cer- 

 tain individuals till June. [Bulletin, March, 1884, p. 290.]
