Show V Flth Know Colors. "Fish know colors." said a keeper 'i at the New York Aquarium the other day. "They can distinguish between '. rod and blue, or white and green, as J well as you nnd I, Walt and I'll prove A ft." ji Ho led tho way to a tank in which ' were some red and some yellow and some green fish, and In It wero nrtl- 4 flclal grottoes painted respectively red and yellow and green. Tho keoper m rolled tho water with his hand, and tho fish fled, tho red ones to the red if grotto, the yellow ones to the jellow 3 grotto, and the green ones to the green 13 grotto. fl "They know which color shlolds ,JI them from observation best," said ho. ' H "Now I'll change the grottoes, so as to H prove my statement a second time." j He moved the grottoe to different M places in the tanks and again rolled J tho water. 9 The same thing followed as Lcforo. '! Each fish darted like a shot 'o tho Wk grotto of Its own color, where It knew N It would bo bast concealed. |
