of salmon, carp, tench, and those other kinds of fish of Which the 

 French people are so very fond. At Huningen, also, there is 

 another extensire establishment for the production of fish, in 

 Which trout and other fresh-water fishes are propagated in my- 

 riads, and the neighbouring rivers and streams are supplied with 

 stock from this useful reservoir. 



" Mr Shaw was the first person in this country, we understand, 

 to direct his attention to the subject. His experiments were 

 made about twenty years ago ; but differed ia their object from 

 these of Jacobi, inasmuch as they were undertaken principally to 

 solve a problem in the natural history of the salmon. In 1848, 

 Mr. Boccius, civil engineer, published a work on Fish in Rivers 

 and Streams : a Treatise on the Production and Management of 

 Fish in Fresh Water^ Ifc., Sfc. This gentleman had taken up the 

 subject in 1841, and made several very successful experiments. 

 In the rivers of one estate alone he is said to have reared up- 

 wards of 120,000 trout. He Was also employed to conduct ex- 

 periments at Ohatsworth and many other places. 



" The system of artificial fecundation has likewise been tried in 

 Ireland. Two English gentlemen of capital and enterprise, 

 Messrs: Ashworth, of Egerton Hall, near Bolton, having purcha- 

 sed the fishery of Lough Corribb, were determined, if possible, 

 to solve the much-discussed question^— " Can the salmon-fisheries 

 of this kingdom be restored to their former abundant state of 

 productiveness?" Mr. Ramsbottom, of Olitheroe, was engaged 

 by these gentlemen to conduct the experiments, which were 

 made as follows, and are described by Mr. Halliday in his letter 

 to the Commissioners of Fisheries in Ireland j a passage of which 

 we beg to quote : — 



" ' On the 14th December, 1852, a small rill at Outerard, was 

 selected for the experiment, by a rude check thrown across ; a 

 foot of water-head was raised over a few square yards to insure 

 regularity in the supply. From this headj half-foot under sur- 

 face-level, three wooden pipes, tWo inches square, by a few feet 

 long, drew off respectively to the rill-bed and to the boxes all 

 the water required — the surplus of the supplying rill passing
