escaped from the vessel altogether. In each of these vessels he 
placed a layer of gravel, and laid upon it a quantity of salmon 
eggs. His supply of water came from a cistern, and flowed 
through an ordinary tap, the only precaution being to keep the 
stream constantly going, and this it may as well be stated is an 
absolute necessity, if trout or salmon ova are to be successfully 
hatched. 
In the year 1854 Professor Coste founded the important fish- 
cultural establishment so well known as Hiiningen, and by its 
means large quantities of fish ova were distributed. Being 
situated in Alsace it fell into the hands of the German Government 
in 1871, and under the directorship of Mr. Hermann Haack has 
since then, as before, done very good work. The hatchery and 
ponds are said to cover upwards of eighty acres, which gives some 
idea of the extent of the work. A large space in the chief building 
is devoted to the hatching of the ova of the Sa/monida, but ova of 
many other kinds are also dealt with. From half-a-million to a 
million salmon ova are hatched each season for stocking the 
waters of the Rhine, which is near, and the Government pays for 
this work. 
The young salmon are reared in concrete tanks which are 
also used for other fish, and answer the purpose admirably. The 
Governments of Germany, Switzerland and the Netherlands, have 
shewn their interest in the important work of fish culture, which 
has been going on for some years, and it is largely due to this fact 
that it has made such rapid strides in these countries. Public 
waters are being restocked and private enterprise is encouraged. 
In Saxony fish culture has been helped by courses of lectures 
which have been delivered by Professor Nitsche of the Academy 
of Forestry. The lectures, illustrated by diagrams, specimens and 
apparatus, have dealt with the subject in a very exhaustive 
manner. 
The knowledge which had been gained was by degrees 
increased and fish culture has prospered in France, until to-day 
there exists at Gremaz in the Department of the Ain, one of the 
most perfect systems of fish culture of the present day. Fish are 
reared on the natural food produced in the water, and herein lies 
one of the great secrets of success in the rearing of trout fry.
