ing, but rainbow possibly differ from other trout in this 
respect, for when these fish were resting during their 
spawning operations, they were always ready to feed, 
and on one occasion I threw in fifty meal-worms one 
after another, not one of which was allowed to reach the 
bottom, and the last was taken as keenly as the first. 
During the spawning, no fish were permitted to come 
near the redd, but in addition to driving them off, the 
male rainbow constantly made excursions over the pond 
with the deliberate intention of biting and chasing the 
other fish, and there was hardly a roach in the pond 
that had not been marked by him. 
The observation of various trouts as seen from below 
the surface of the water also enables one to appreciate 
their agility, and the perfect control that they have over 
their movements. When a trout lying near the bottom 
rises to a fly on the surface, he comes like a flash of 
lightning, and so rapid are his movements that even 
with an exposure of 5}, of a second, it is impossible to 
get more than a blurred image. But should a trout take 
up a position a foot or so under the surface of the water, 
it is possible to watch closely his movements as he rises 
to a fly, and also obtain fair photographs with a quick 
exposure.

comes up at an angle of about forty-five degrees, and 
sucks it down, and then as he again descends, he breaks
