NOTES ON THE RATE OF TRAVEL. 
Observations on this point are obviously unsatisfactory and unreli- 
able. While the times and places of release and of capture of given 
fish may be accurately determined, it can not be stated in any case 
what route the fish has taken or how long it may have been in a locality 
before it was caught. Without laying undue stress on this subject, 
the records of a few cod which were caught a short time after their 
release may be examined. It is evident that the sooner a fish was 
captured and the less time it thus had to roam, the more accurate was 
the basis afforded for determining how fast it moved. 
Some fish appear to have moved rapidly away as soon as released, 
while others remained in the vicinity and, when caught, had traveled 
only a few miles. 
The tagged cod recaptured in the shortest time after liberation (No. 
820) was released in Vineyard Sound, 3 miles SSE. of Tarpaulin Cove 
light, on December 24, 1898, and was caught 4 miles south of Newport, 
R. I., on December 26, 1898. The distance between these two points, 
by the most direct water route, is 33 miles. 
Quite a number of fish each season were taken on the shores of Long 
Island within a comparatively short time after being liberated. Thus, 
No. 360, released January 22, 1898, 2 miles NW. of Gay Head light, 
was caught February 4, 1898, off Westhampton Beach, New York; 
time, 13 days; distance, 131 miles. No. S 10, released January 25, 
1900, 1 mile SW. mouth of Woods Hole Harbor, caught February 
12, 1900, 3 miles off Amagansett, New York; time, 18 days; distance, 
88} miles. No. S 43, released on the same day as the preceding, 
caught February 7, 1900, 2 miles off the same place; time, 13 days;
