230 REPORT OF THE COMMISSIONERS OK 



ridiculous story started by persons of no principle, to the effect that many pounds of 

 trout were sold from the weir. It is unfortunate that the experiment could not have 

 been conducted during such a season as the present (1900), when all conditions of 

 Nature have been quite propitious, and we have not had one rain during the entire 

 spring that would have been strong enough to have vitiated in the least any of the 

 desired results. We were anxious to make as much of a study as possible of the 

 movements of fishes as well as of the lampreys, and consequently kept the following 

 records very carefully. A summary is given at the end. Beginning with May 1st, 

 two columns are given to each date. The first is for the morning catch, which was 

 taken out about 6 A.M., having run into the trap during the night; the second is for 

 the evening catch, taken out about 6 P.M., and having run into the trap during the 

 daytime. It will be observed that most fishes and lampreys move up at night. 

 " Clearness of water" is given in relative numerals, " t " meaning quite clear, and "5" 

 extremely muddy ; intermediate numbers stand for grades of turbidity. " Height of 

 water" is also according to an optional standard. In the tables ." m " is used to 

 designate male, and "f " is used for female. Where no sign is prefixed, the surface 

 of the water was above this mark, and where the minus ( — ) sign is prefixed, it was 

 below the mark.
