2 artificial techniques used, that is, the asserted live 



3 box and laboratory results, and the attempt to say that 



4 such results have any significant meaning in nature. 



5 For example, to say that the results of the juvenile 



g salmon live box experiments are of any consequence would 



7 be the same as saying that the death of some robins held 



g captive in a sack attached to the exhaust pipe of a car 



g would prove that automobile exhaust fumes are "doing 



jQ extensive damage" to our bird populations. Moreoever, 



jj other than the live boxes in immediate proximity of out- 



j2 falls or sludge beds^ no abnormal mortality was found. 



13 The attempts to attach any importance 



14 whatsoever to the results of the so-called oyster larvae 



15 bioassay are even more unrealistic. We cannot find any 

 Ig pertinency in the failure to rear a delicate form of life 



17 in a laboratory beaker under completely unnatural con- 



18 trolled conditions, and the lack of pertinency becomes 



19 doubly apparent when it is realized that the form of life 



20 involved is never--! repeat never--found in these waters. 



21 Would the failure to rear such a form 



22 using the effluent from a secondary treatment sewage plant 



23 mean that all cities must, therefore, evaporate and burn 



24 85 percent of their final sewage effluent? 



25 One further point. We regard the
