REARING THE YOUNG FRY. 175 or Mr. Furman's on Long Island, can doubt that others can raise them in other places and make them live. The beginner may accept these axioms in raising trout: — 1. No trout dies without a cause. 2. The causes of death are discoverable. 3. They can, in most instances, be removed. My own experience has invariably been to confirm these principles. I lost in my apprenticeship days as many young fry as any one else ; but with every death, say over five per cent, there appeared a distinct assign- able cause, present or remote, which could be re- moved or avoided next time; and the more I lost the more I became satisfied that the causes of death among the young fry could be discovered and avoided. My later experience has added confirmation to this opinion. And now, since I have used charcoal troughs and tanks altogether, deaths among the young trout have been, among some lots, rare occurrences, and in general have been no more frequent — over the five per cent weak ones— than among the yearlings and breeders. In one charcoal trough, in particular, containing over five thousand, there was, in the season of 1870, less than one per cent cf deaths from all causes in three months. It has been the same this year (1871). In one box of a thousand I have not taken out ten dead ones in three months. I attribute this in a great degree to the use of cha.^oal in hatching, but it con-. m^^.
