Perhaps the most interesting, certainly the most unexpected of 

 these, is that young Cod and Haddock have appeared so seldom in the 

 hauls, though both these species, particularly Haddock, spawn in large 

 numbers in the Gulf; their eggs occurring more regularly in the tow- 

 nets than those of other fish (p. 257); and we have never taken an}- 

 Mackerel iry in the Gulf, though Mackerel eggs are by no means rare 

 there (p. 264). Since the nets in use were all adapted to the cap- 

 ture of the small frv, and did yield considerable numbers of other

young fish, notably Sebastes, and Merluccius, it can hardly be sup- 

 posed that if Cod and Haddock larvae were as numerous as Silver 

 Hake fry the nets would consistently miss the one, and capture the 

 other. Consequently, even if the youngest pelagic stages of Cod and 

 Haddock are not as rare in the Gulf as the records suggest, there is 

 good reason to conclude that they are not abundant there during the 

 summer. Furthermore, the few records of young Cod and Haddock 

 are all grouped in the southwest corner of the Gulf (Fig. 86), though 

 their eggs were as abundant in the east as in its west side; and our
