208 BULLETIN OF THE UNITED STATES FISH COMMISSION. 



" The invention, about to be patened, is the construction of a car for 

 the transportation of fresh salt-water fish, by employing a tank, by intro- 

 ducing into this tank fresh air, which is absolutely necessary to the well- 

 being of fish, the air having jtreviously been cooled, and the superfluous 

 air having been shut ofl" from the ice-box, with a view of keeping the 

 air in the tank at a slight tension, so as to prevent any violent motion 

 of the water. 



"This car is to serve for the wholesale transportation of salt-water 

 fish from the coast to some central point in the interior." 



If this invention fulfills all it promises to do — and it is to be supposed 

 that the capitalists who have made it possible to carry out its theory 

 in practice have thoroughly convinced themselves of its usefulness — 

 Mr. Pachaly deserves the gratitude of all fish-dealers. A beginning has 

 been made, and circumstances will finally compel the disobliging rail- 

 road companies to be far more accommodating in the matter of trans- 

 porting fish than they have hitherto been accustomed or willing to be. 



MEMORABTDUM OF SOME RESUL,TS OF THE ARTIFICIAL, PROFAOA- 

 TION AIVB FliAIVTIIVO OF FISH, DUE MAIIVI.,Y TO THE EFFORTS OF 

 THE UIVITEI) STATES FISH COJUIUISSIOIV. 



The following chronological sketch shows some of the work accom- 

 plished within the last decade by the United States Fish Commission, 

 either directly by its own efforts or indirectly by its co-operation with 

 State commissions. It is, however, very far from complete, and the ob- 

 ject of publishing it is only to place on record some scattering items 

 preliminary to a more elaborate and complete article on the subject. 

 The United States National Museum now has many specimens illustrat- 

 ing successful introduction of important species, and these are recorded 

 in this article. The fishes from which returns have been received are 

 as follows: 



1. German whitefish {Coregomis lavaretus). 2. Maine salmon (Salmo 

 salar). 3. Quinnat salmon {Oncorhynchus chouicha). 4. Eainbow trout 

 {Salmo irideus). 5. Shad {Alosasapidissitna). G. iJiirp{Cyprinuscarpio). 

 7. Catfish {Amiurus catns).

April 28, 1877. — Geo. H. Jerome, superintendent, writes: 

 "My overseer, Mr. Chase, informs me that but 409 of the 1,700 Ger- 

 man whitefish lived to be planted in Michigan waters. The number 

 which survived were very active and healthy, and were i)laced, on the 

 14th of April, in Gardner Lake, Otsego County, a small deep lake, 

 where no whitefish had ever been i^lanted, and free from all jDredaceous 

 fish. The eggs were a little larger than our whitefish eggs. The fish 

 had a larger sac and carried it longer than our whitefish."
