PHOTOGRAPHING FISH 107 



glass so that it comes on the extreme edge of the 

 plate. Then, when the photograph of the fish is 

 made you have the name on the negative. This 

 prevents any possibility of error. The paper label, if 

 wet, will adhere to the glass, and may be removed 

 without any difficulty. 



In photographing fish that are habitually found in 

 swiftly running water, some device might with advan- 

 tage be used in order to keep the vegetation bending 

 over, all in one direction of course, thus giving the 

 effect of a current. This may be accomplished by 

 attaching a very fine thread to each plant, that they 

 may be drawn over to the proper angle. This is 

 rather a "fake" way of doing it, and not altogether 

 satisfactory. A more elaborate method would be to 

 have several large openings at one end of the aqua- 

 rium through which the water would run freely, 

 while on the other side an equal quantity of water 

 would have to be admitted. Though I have never 

 tried this, I believe it would give a good effect of 

 swiftly running water, which would not only keep 

 the plants in the desired position, but would force 

 the fish to assume a natural and lively attitude, as 

 though it were in a brook. The rapid movement 

 of the fins would, of course, necessitate a very short 

 exposure. 



With surface fish it is a good plan to have the 

 water several inches above the partition glass ; then, at
