tly incapable of negotiating the smallest waterfall. I have seen thousands of Pacific salmon stopped hopelessly by a fall which would not hinder a small European sea-trout. It may be that the tremendous nature of the journey already completed has robbed him of the energy necessary for leaping, but experience would lead me to believe that the Pacific salmon trusts to immense powers of endurance, which enable him to travel thousands of miles against a frightful current rather than to a short journey and one or two big jumps. This fact is certainly worthy of further investigation and note, in view of the introduction into British Columbia of the Atlantic salmon. There must be numbers of rivers barred to the Pacific fish which would be quite easy of access to the Atlantic. I doubt much if the quinnat could tackle an ordinary artificial salmon ladder, though there are undoubtedly numbers of streams in British Columbia which could be rendered navigable to _Salmo salar_ by such means. A small hatchery established on such a river might at once establish the European fish in these waters. On the other hand it is very doubtful if the present attempt to acclimatise _Salmo salar_ by the introduction of small fry into the Fraser can avail much. Few could hope to survive and compete with the countless myriads of the sockeyes, while it is doubtful if the Atlantic fish could ever make its way for hundreds of miles against the Fraser current. It is not fitted for a slow journey of weeks and even months, but rather for one of some few hours with a strong leap at the end which lands it at once in the destined pool or lake. There are two other points which will strike the fishermen in British Columbia waters. One is the absence of kelts at any time of the year. The other is the fact that, though the waters are often alive with young salmon, none are ever caught on the fly. The first point is explained by the fact that these fish die after spawning. There is no doubt that this is well established, though there is something to be accounted for--namely, the large specimens of each species, which must undoubtedly either be survivors of a former run or else fish which have stayed in salt water to a more advanced age. To take the example of a spring salmon of 80lb.; this fish would, in Europe, be reckoned as at least ten years old and probably a great deal more. Are we to conclude that such a fish has never been into fresh water before, or
