PiSn-WAYS. 



In order that we mi^'lit better make the examination re- 

 ([uired in section 2nd of chapter 150^ Laws 1874, avo selected 

 a time when the Potomac River was very low, to make a sur- 

 vey of the Great Falls 



President Artliur P. Gorman, who has ever manifested the 

 g-reatest interest in the work of the Commission, kindly placed 

 his packet at our disposal, and furnished us with the neces- 

 sary transportation u}) the canal. We invited the Commis- 

 sioners of Fisheries of Virginia to make the survey with us, 

 as both States are e(|ually interested in having- an efficient 

 fish-way constructed over this barrier, to the ascent of fishes 

 from the tide water to the upper portions of the KStates, drain- 

 ed by the Potomac and its tributaries. Colonel A. Moseiy 

 representing his Commission accordingly met us at George- 

 town, J). C, on the 12t]i of July, and we proceeded up the 

 .canal in President Gorman's boat, accompanied by liis courte- 

 ous Paymaster, Mr. Gambrill. By taking the route by water, 

 we were able to examine the Little Falls, and other points on, 

 the river. Major Richard Randolph, Engineer of Baltimore 

 and Ohio Railroad, had kindly promised his valuable aid 

 gratuiously, and liad secured for us the services of two of his 

 .assistants, Messrs. (jordon and Jones, who, under his able 

 guidance, ran the necessary lines, and took the levels. We 

 are greatly indebted to Major Randolph for his experienced 

 advice, and his assistance in making this important ]n-elimi- 

 nary survey, and beg to submit his rep-crt :

 the thousand islets of the fishing grounds; mounting and de- 

 ■scending the numerous rapids with almost the same facility
