SALMON MANUFACTORY. 31 



as well as to those that live entirely in fresh water rivers and lakes. 

 The streams and rivers over a large extent of Erance have now 

 been abundantly stocked with a variety; of fish from this ancient 

 process, more particularly in the vicinity of AUeyard, Vazille, 

 Pontcharra, Sessenage, veary, Bouig d'Oisons Rivis, Pont-en- 

 Royans, Paladru, Lemps, St. George, Avandon, La Euisse, Gre- 

 noble, and in many otner departments of the Allier, the Lozere, 

 the Mense, the Mensthe, and Hant Saone. _ 



At the moment we are penning these lines, we copy from the 

 pages of a public journal, that this mode of propagating salmon is 

 being adopted on the river Tay, in Scotland, on a pretty extensive 

 scale. As the account must be interesting to all the disciples of 

 the rod and line, we make no apology for transferring it here as it 

 is given : 



"THE SALMON MANUFACTORY ON THE TAY. 



" The ponds for this purpose are situated on the river bank, near 

 Storemountfield, the spawning-boxes being 16 feet above the sum- 

 mer level of the river. The water which supplies the ponds is 

 taken from Storemountfield lake (but owing to the impurity of 

 the Tay during spates, a supply is also to be t taken from a 

 neighbouring spring), by a pipe with a valve, into a filtering 

 pond ; thence it is carried lay a canal along the upper end of the 

 spawning-boxes, through which it runs. These boxes are 84 

 feet long by one foot six inches broad, and three deep. They are 

 placed with a fall of six inches, so as to allow the water to flow 

 freely through them, and are partly filled, first with a laying of fine 

 gravel, next coarser, and lastly with stones somewhat coarser than 

 road metal. In distributing the ova, it i s gradually poured out of the 

 vessel at the upper end of the box. The water flowing downwards 

 carries it among the stones, under which it settles down, and by 

 gently applying a few buckets of water at the upper end of the 

 boxes, the ova are taken down and distributed equally among the 

 gravel. When the young fry are in a proper state, they are 

 allowed to escape into a pond situate at a foot lower level than the 

 boxes, where they will be fed, and allowed to remain, until such 

 time as they are in a fit state to be turned into the river. This 

 pond is not yet made, but will be finished by the time the fry are 

 hatched. Great care has been taken to prevent any animal 

 entering with the water that would prey upon the fish. Mr. 

 Ramsbottom, from Clitheroe (who has experimented successfully 

 for the Messrs. Ashworth, on the Lough Corrib waters, in Ireland), 

 has the sole management of the Tay ponds. Saturday was a 

 remarkably fine day for the season, ana we were privileged in 

 being present at the operation of stripping the fish. When we 

 arrived, Mr. Ramsbottom had already got about 15,000 ova in 

 round tin cans, and he showed us an oval-shaped tin box with a 

 lid, which contained a small male fish swimming in water, which,
