go MARVELS OF FISH LIFE 
does not remain here, for continuing his progress he 
swings round, almost invariably the same way each time, 
and comes to rest within an inch or two of the place 
from which he started. 
The whole manceuvre is an uninterrupted glide, and 
it is difficult to realise the speed at which the trout is 
moving until an attempt is made to photograph a rise 
as seen from below the surface of the water. The two 
illustrations shown were taken on a bright day, and the 
photographic working details were :— 
Exposure, ,}, of a second; lens aperture, f4; plate 
speed, H and D 400; distance of lens from the fish about 
seven feet, and yet the fish going across shows consider- 
able movement. In explanation of the two photographs : 
the top one shows the trout having completed the rise, 
and the fish is seen end on in the act of coming round. 
The bottom illustration shows him going across. He 
then swung round once again, and was in position for 
the next fly. 
It may seem extraordinary that a trout will come 
back time after time to the same place in the water when 
apparently that place is no better than a foot or two 
higher up, but every dry fly fisherman will confirm the 
fact that he does so. 
The power of controlling their movements is well 
seen when a worm is thrown into the water, and two 
fish rush at it from different parts of the pond. Arriv- 
ing at the food about the same time a collision seems 
inevitable, but I have never seen trout actually strike
