1902-3.] Mr Wm. Murray on Salmon in American Rivers. 477 
been salmon culture by the State. In all of these substantial im- 
provement has resulted, showing that the system of administration, 
when unaided by artificial culture, has been fairly successful in 
attaining its ends. To return to the Grand River and Gaspe table, 
the conclusion from it seems to be that the best way to improve a 
Penobscot River.

{a) In 1868 the catch was estimated from imperfect data at 8000 fish. 
(6) This column is a necessarily imperfect attempt to reach approximately 
the output of fry by the U.S.F.C. into the Penobscot. Fry were bred during 
the years 1885-1888, but details of distribution are not at hand. Owing to 
similarity of names of places the exact spots where fry have been liberated in 
several of the other years have been difficult to discover, and this may have 
occasioned inaccuracy. To the column may be added a proportion of the eggs 
given by the U.S.F.C. to Maine State, amounting in all to some 3J millions, 
so far as can be discovered. 
(c) Y = Yearlings. 
( d ) It appears from a letter to the “Field,” 5/10/1901, that the yield in 
1900 was not arrived at, but was apparently less than that for 1899; while 
the yield for 1901 was 7161 fish. 
(e) Numbers of fish estimated in these years.
