The process of hatching was much more protracted than was anticipated; it was not till the 8th of June that the last of the eggs gave forth its little tenant. An account of the daily hatching was kept up till the time that 1000 of the eggs had arrived at maturity, but after that the hatching went on with such rapidity as to render it impossible to keep a correct record. Up to the 16th of June the trout had not been artificially fed, but for all that they looked healthy and grew fat. Mr. Ramsbottom computed that he had at least 3000 healthy salmon, rather a small percentage certainly to obtain out of the 30,000 eggs, but quite sufficient to solve the grand problem of whether or not it were possible to introduce the British salmon into Australian waters. The latest accounts tell us that the young parr are doing well, though they are not growing so fast as the trout.[4] The further progress of the experiment will be watched with great anxiety both at home and abroad. The Tasmanian Legislature have voted a further sum of £800 for the purpose of introducing another batch of ova; this sum will be augmented by £400 voted by the Victorian Acclimatisation Society; so that no means will be left untried to bring to a successful conclusion this great experiment—the ultimate result of which, I have no doubt, will be, that the salmon will become as valuable a fish in the waters of the great Australian Continent as it is in the waters of our own islands. The naturalisation of fish, to which a brief reference has already been made, is a subject that is not very well understood; but so far as practical experience goes, I have seen nothing to prevent our breeding in England some of the most productive foreign kinds. Among the fishes of China, for instance, in addition to the golden carp—now quite common here, and bred in thousands in nearly every factory pond, and which is looked upon as simply an ornamental fish—there is the lo-in, or king of fish, which frequently measures seven feet in length, and weighs from fifty to two hundred pounds, the flesh being excellent; the lien-in-wang and the kan-in, almost as good, and even larger than the other. Then there is the li-in, the usual weight of which is about fifteen pounds, and is said to be of a much finer flavour than our European carp. There are many other choice fishes of exquisite flavour, which it is unnecessary to enumerate; but I have no doubt that, besides these natives of Chinese seas, there are numerous other fine fish that might be acclimatised in our rivers and firths. The seir fish of Ceylon may be named: it is a kind of scomberoid, and in shape and size is similar to the British salmon. We must not, however, build ourselves much on the acclimatisation of foreign fish, especially tropical fish, as—although fish can bear great extremes of temperature—it would be no easy matter to habituate them to our climate. Indeed some writers think it will be found impossible to habituate tropical fish, however
