FISH PHOTOGRAPHY AT HOME 185 
case proudly shows me these tench, for I shall then be 
able to offer him a photograph of them, taken when 
alive, and twenty-four hours after they were fished 
out of the mud. 
Finally, my friend Mr. Richmond has from time to 
time sent me Loch Levens, rainbows, Windermere char, 
and good specimens of commoner fish. 
When a fish arrives from a fish farm it has travelled 
in a large can constructed for the purpose, and is pro- 
bably quite fit. But often a fish brought by a friend is 
half dead, for though many people can catch fish, few 
know how to keep them alive. 
The first thing, then, is to revive the fish. Let the 
cold water tap run with full force into the bath, and 
hold the fish two or three inches under the water, with 
the bubbles of air rising all round its snout. If this is 
insufficient to revive the fish, pour a little weak whisky 
and water down its mouth, or swab the gills with cotton 
wool dipped in the same restorative. A fish is never

Once revived, place the fish under conditions to 
ensure its convalescence. This is best done by keeping 
him in shallow water, the surface of which is being 
continually disturbed; fish will keep healthy during 
long periods in water so shallow that their back fins 
appear above the surface, whereas they will die in a 
bucket full up to the brim. The reason for this is that 
in shallow water a large surface in proportion to its bulk 
is exposed to the air, and in consequence the water
