DEAD FISH IN THE AVON.

to IBS XDITOB or THE PBBBB. Sirln reply to a letter signed by "A. Lex,'' who advances the theory that the dead tirout seen floating down the Avon last Saturday were poisoned by deposits of tar, which were washed off the streets by recent rains, 'I would like to point out the following facts: — 1. If the fish poisoned by the film of tar, it could easily be seen on the surface of the river, were it in sufficient quantities to act as a destructive agent, but it was not apparent. ' 2. No ill effects were noticed above the Armagh street Bridge, though side channels, drain into the river above this place. Thus' it points toward some concentrated form of poison. 8. Before Saturday last there were only a few showers while the heavy rains of some six weeks ago were not • responsible for poisoning any fish. From these facts it can be easily seen that poisoning was not caused by any deposit of tdr or oil on the surface, but by something which was iij soluble form in the water and which could only be detected by analysis.— Yours, etc., I INTERESTED.
