the fish other than shad are concerned they have been successful in 

 Pennsylvania. 



Mr. Graham : I referred especially to shad. There is a great field 

 for some inventive mind, because no one has as yet invented a means 

 whereby the shad will go up. 



Mr. Meehan : During tbe last few months of my tenure of office I 

 was bitterly criticised for putting in a fishway at this dam 60 feet high, 

 which was "utterly useless because the shad would not go through." 

 Possibly it might be interesting to know that on the York County side 

 of the dam — the right bank of the Susquehanna — is a pile of rocks 

 that readies within 10 feet of the crest of the dam. We noticed last 

 spring that there were two or three pools in tbe river formed by a 

 series of rocks, and a number of shad succeeded in getting to the 

 topmost pools, or within 10 feet of the crest of the dam. I got in com- 

 munication with the company owning and controlling this big dam 

 (McCall's dam); and when 1 went out of office they were preparing 

 plans for an artificial series of rock pools to be made clear to the crest 

 "I" tbe dam; so that the shad could reach one pool from the other. We 

 had hopes it would be effective in letting some shad at least go up into 

 the river above. There was a fair prospect of it at any rate, from 

 what we had seen. 



Secretary Bower: Just a word anent tbe Cail fishway, of which 

 mention was made. After many years of experimentation and investi- 

 gation, the Bureau of Fisheries has adopted what is known as the Im- 

 proved Cail Fishway. The original Cail fishway has been modified 

 by Mr. Hector von Bayer, the architect and engineer of the Bureau of 

 Fisheries. Whenever he receives any communications on the subject 

 the interested persons are referred to this particular form. It is de- 

 scribed in a pamphlet issued by the Bureau about two years ago. Draw- 

 ings, blue prints and directions are furnished on application. 



Mr. W. O. Buck, Neosho, Mo.: There is a fishway on the Penob- 

 scot at Bangor designed by Mr. Atkins, which he told me was exam- 

 ined at one time by himself and the state commissioners and found to 

 contain salmon in every pool. It is intended especially for salmon 

 and consists of a double spiral of pools on the plan of the Cail fishway. 

 He considerd it a success for salmon. 



At the head of a branch of the Penobscot in the town of Orland 

 there was a small fishway to enable alewives to pass a dam some twelve 

 feet high, arranged on somewhat the same principle, that is, in pools; 

 being a narrow sluice divided by transverse partitions having openings 

 "ii alternate sides of the sluice by which the water fell from one pool 

 to the next. Both of these I understand to be of the Cail fishway 

 pattern. 



Mr. Atkins' article on lishwavs published in one of the earlier re- 

 ports of the U. S. Fish Commission — 1 think that for 1878 — was a 

 very complete summary of all the fishways in use at that time. The 

 article would be a valuable reference in studying different styles of 

 fishways.
