 cially tlie j^atheiiiig and aitifieial iinprcgnatiou oftlie eggs oi" the wliite- 

 fisli, arrangements were made with Mr. Frank N. Clark, of Nortbville, 

 Michigan, to secure and bring forward snch a number of eggs as might 

 be needed by the Connuission to meet tlie comparatively small nund>erof 

 applications, the most important of these being from California, Nevada, 

 and several foreign countries. Accordingly, 500,000 eggs Avere shii)pe<l 

 to Mr. I>. B. Itcdding for the California commissioners. The shipment 

 of the eggs was quite successful, a comparatively small percentage failing 

 to develop. The eggs were packed by Mr. Clark between layers of mos- 

 quito netting, and Mr. Eedding reports that where the layer of netting 

 was single the eggs were iip good condition, but where they rested on a 

 fold or turn they were generally killed, thus suggesting an inq)ortant 

 precaution under these circumstances. The young fish thus obtained 

 were for the most part i)laced in Lake Tahoe. 



Desii'ous of trying the experiment of the introduction of our whitefish, 

 Corcf/onns albus, into Germany, I instructed Mr. Clark to put up and 

 forward to Mr. Fred. INTather, for shii^ment to Germany, a package of 

 50,000 eggs. These were started on the ISth of January, 1878, and on 

 the 21st Mr. Mather acknowledged their receipt at Newark. As no 

 steamer was up for Germany until the 2Gth of January, Mr. Mather kept 

 the eggs in his cellar at a temperature of 10°, a piece of ice being allowed 

 to melt continually on the top of the box. The authorities of the North 

 German Lloyds having, with their usual liberality, agreed to forward 

 these eggs without expense, they were placed by Mr. Mather, on the 2Cth, 

 in charge of the first officer on the Mosel, by whom they were put in a 

 part of the vessel which, unfortunately, proved to be too warm for them, 

 as, on their arrival in Germany, all were found to have perished. 



Through the mediation of the United States Fish Commission, ar- 

 rangements were made between the Government of New Zealand and 

 Mr. Frank N. Clark for a supply direct of embryonized eggs of white- 

 fish. This connuission was satisfactorily executed by Mr. Clark, and 

 the eggs duly placed on board the steamer at San Francisco, and reached 

 their destination in good condition. A large percentage was hatched 

 out, and the young placed in antipodal waters. 



The European Marane Whitefish {Corcgoniis marcena). 



The value of the Coregonus or wdiitefish as an article of food and as a 

 subject for artificial propagation is becoming appreciated in Germany, as 

 it is in the United States ; and the German fish culturists are especially 

 actii^e in experiments and suggestions. A favorite species is what is 

 known as Madue Marcene or Coregonus Marcena of (Bloch.) This is found
