rivers east of the Alleghanies ; because if they should increase 

 they would soon extend to all the tributaries of these streams. 



The speaker, to illustrate his meaning in this particular, 

 proceeded to explain the peculiar and tortuous conformation of 

 the water-shed of Pennsylvania. There would be no difficulty, 

 by this means, in supplying the streams east of the Alleghanies. 

 Black bass had been placed in the Delaware and Susquehanna 

 Rivers some seven years ago by private individuals, and the 

 result has been that both of those great streams are now supplied 

 by that magnificent fish, a thing worth ten times all the money 

 spent by the State of Pennsylvania on fish culture. 



The presiding officer here invited a continuance of the dis- 

 cussion. 



Mr. Seth Green remarked that he could explain the cause 

 of the disappearance of the shad, this being because the waters 

 were over-fished. He thought there should be a close time for 

 shad, at least forty-eight hours in a week. He said that one 

 reason why the shad do not ascend the fish-ways in great 

 numbers, is that they are generally netted at the foot of the 

 dams, or in close proximity thereto, and this frightens away 

 those that are not caught. He thought that the fish-way 

 invented by Mr. Brewer of Muncy, Penn., was the best one 

 now in use. It had been tried in New York, and had worked 

 with great success. It was built to face the dam, and not on the 

 side, as most others are constructed. Ways built like this the 

 fish will find, but those on the side they will seldom find. 



Mr. Weber expressed the belief that, as a general thing, the 

 fish would not use a straight fish-way, but that a semicircular 

 fish-way, such as the one adopted by the Massachusetts Fish 

 Commission, would prove of the greatest practical utility.
