REPORT OF COMMISSIONER OF FISH AND FISHERIES. XXVII 
9.—FISHERY CENSUS OF 1880. 
In the report for 1879 an account was given of the arrangements en- 
tered into with General Francis A. Walker, Superintendent of the Tenth 
Census, for procuring an exhaustive review of the fish and fisheries of 
the United States. The plan of investigation which was there given 
in full has been steadily pursued, and a large amount of material aceu- 
mulated. 
Although Mr. Goode, who is in charge of this investigation, was very 
largely preoccupied, from February until July, by the preparation for 
the Berlin Exhibition and by his absence in Germany, the field-work 
was nevertheless continuously prosecuted by the various special agents, 
so that by October Ist the Great Lake region, the Gulf of Mexico, and 
the Pacific coast had been substantially completed. The work on the 
Atlantic coast had proved so much greater than anticipated that Messrs. 
hk. E. Earll and Capt. J. W. Collins were obliged to prolong their field 
labors and to hurry over the latter part of their work more than they 
would have preferred to do. 
Upon the return of Mr. Goode to Washington from Berlin he directed 
this investigation from Newport, as has already been intimated. Harly 
in October his headquarters were moved to Washington, and the work 
of writing up the final report was energetically entered upon, several 
of the assistants reporting at Washington for this work as fast as their 
field duties were completed, and others compiling their data at such 
places as were most convenient to them. 
Mr. Ludwig Kiimlein being obliged by his business engagements to 
withdraw from the work, his notes were placed in the hands of F, W. 
True for compilation. 
In addition to and co-ordinate with the field work, an extended line 
of inquiry had been pursued by means of circulars and lists of ques- 
tions. A very large number of replies to these having been accumu- 
lated, those of one single inquiry numbering over 30,000, the work of 
arranging and compiling them was assigned to Mr. Charles W. Smiiey, 
who, with several assistants, had had the entire charge of their issue. 
A force of from twenty to thirty clerks was detailed to his assistance 
from the Census Office by General Walker. 
By the close of the year the reports on several subjects had been 
completed ready for the press, and many others were in a satisfactory 
state of advancement.
