THE DRAWING OF THE SEINE. 157 



gence as Mr. Romanes believes. This view of the in- 

 tellectual status of fishes is further strengthened by the 

 consideration of their possession of a color-sense; and 

 here I cannot do better than again quote from a recent 

 work by the same author. 



In his " Mental Evolution in Animals," * Mr. Romanes 

 remarks : " As further proof that a well-developed sense 

 of color occurs in fish, I may remark that the elaborate 

 care with which anglers dress their flies, and select this 

 and that combination of tints for this and that locality, 

 time of day, etc., shows that those who are practically 

 acquainted with the habits of trout, salmon, and other 

 fresh-water fish, regard the presence of a color-sense in 

 them as axiomatic." As one "practically acquainted" 

 with some sixty species of fresh-water fishes, represent- 

 ing a dozen or more distinct groups, I am reminded, by 

 the above quotation, of many occurrences witnessed dur- 

 ing my rambles about the Delaware River, or its tribu- 

 tary creeks, that have a bearing upon the subject. Be- 

 sides recognizing the differences in insects by their colors, 

 have fishes any knowledge of the fact that tiieir own 

 colors may or may not be protective? Are they aware 

 that it depends upon themselves whether these colors 

 shall be a safeguard, or a source of danger? That we 

 are warranted in giving an affirmative reply is shown, I 

 think, by their habits, and particularly by the fact that 

 to a certain extent they have the color of their bodies 

 under their control.
