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 Merfimac, 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 ginee carried out, at a 

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

 hope that it will prove to be g, ' success.'
