CULTURE OF THE SHAD. 167 



Massachusetts, to Theodore Lyman, Esq., who has charge 

 of the subject in that state. 



" In Connecticut I was informed by Mr. Avery that they 

 did not consider the river (the Connecticut) obstructed by 

 any works of theirs which existed in it, and that they so 

 intended to answer the state of New Hampshire, that 

 state having officially requested to know if any such ob- 

 structions existed. 



" In Massachusetts I found that they had not advanced 

 in these improvements further than we had, they being 

 just then engaged in devising plans for the Merrimac, and 

 perhaps other of their streams. 



"They, however, had given intelligent consideration to 

 the subject. 



"Mr. Lyman is well known as a naturalist, and he had 

 availed himself of consultations with Prof. Agassiz, whose 

 reputation, I need not say, is, in the same pursuit, world 

 wide. I could not learn that in the other states of New 

 England I would be able to add to the information obtain- 

 able from these high sources in Massachusetts, so I pro- 

 ceeded no further than Boston. 



" In July I met Mr. President Knight again on the dam 

 at Columbia, and there, in consultation with himself and 

 Mr. Daniel Shure, the able superintendent of the Susque- 

 hanna Canal, a plan was devised, chiefly by Mr. Shure, 

 with some modifications suggested by my New England 

 experience, which plan has been since carried out, at a 

 cost of some $5000 to that company, and I have reason to 

 hope that it will prove to be a ' success.'
