 sition at Berlin). Metz, 1880.] 



Everytliing whicli America had sent was on a magnificent scale. The 

 American exhibit was distinguished by the enormous number of objects 

 placed on exhibition, giving not merely a faint image of the fisheries, 

 but a complete view of the fresh-water and salt-water fisheries, for the 

 greater part in original representations. The American exhibit was 

 moreover distinguished by the neat workmanship of all the objects and 

 by an exemplary arrangement which in all x)articulars showed the prac- 

 tical man. It is impossible to enter into details, as this would take up 

 our entire space, for the American department was a complete fishery- 

 exposition in itself. 



We shall, therefore, only cast a rapid glance at the numerous boats, 

 both originals and models, examine a little more closely the "dories," 

 so much admired by all connoisseurs, learn to know the portable canoes 

 of the Indians and trappers made of bark and skins, admire the truly 

 magnificent scientific collection filling several rooms, and finally devote 

 some time to the department of pisciculture. 



Much of the apparatus on exhibition was already known to us, as for 

 about three years we have imitated the Americans in this respect; thus 

 we know the Holton apparatus, the Wilmot hatching-funnel (really, as 

 we now learn, invented by the well-known American pisciculturist, Fre'd. 

 Mather, who twice already has safely transported eggs of the California 

 salmon to Europe); the Seth Green shad apparatus, &c. But lost 

 in astonishment we stand before the large model of the Fish-hawk, a 

 large steamship specially constructed by the American Government for 

 purposes of pisciculture. This steamshii) contains, both in its interior and 

 on its sides, hundreds of large pieces of apparatus for hatching fish-eggs. 

 The steam-engine partly serves for pumping up the water, thus producing 

 a constant current of water through all the apparatus inside the vessel, 

 and partly for moving to and fro in tbe water the appa;^atus attached to 

 the sides of the vessel, thus vivifying the germs of the eggs. This govern- 

 ment steamer visits the principal fishing-stations during the spawning- 

 season of the shad — a fish closely resembling our " May-fish " {Alosa) — 

 takes up hundreds of millions of impregnated eggs, develops them further 

 in the manner described above, and, when the young fish have been
