fish sunning itself at the surface of some in- 
land pond, now and then; but it is unlikely 
that a fish hawk would come down into the 
garden. 
Night herons which are apt to pay a visit be- 
tween sunset and sunrise are usually looking 
for frogs. Frogs have an omnivorous appetite, 
and whereas the little ones are probably all 
right, be suspicious of a big frog which takes 
up its residence in the pool ; and if the fish are 
disappearing, send him on his way. Be on the 
lookout for the big, oval, brown, giant water- 
bug, two inches or more long (Belostoma) a 
highly predacious creature which captures and 
sucks the juices of small fishes. It will be hid- 
ing about the edges of the pool, under stones, 
or in any rubbish there may be. It is at- 
tracted by lights, and has lately been also 
called electric-light bug. If one of these is 
found in the pool it must immediately be 
gotten rid of. 
VEIL-TAIL GOLDFISH 
Member of an extraordinarily decorative family, this gentleman seems 
almost to be guilty of conscious posing with an eye to Japanesque effect 
adapted, but the writer has found them in puddles in the wheel- 
ruts of a road in Florida, where they obviously had not been 
planted. 
U NFORTUNATELY for the purpose of the present article 
there exists little classified data as regards keeping these 
little fishes in northern outdoor waters, or their efficacy as mos- 
quito checks when so kept. Probably they are the best fish for 
that purpose, but their use is still in the experimental stage, and 
in trying them one is doing more or less pioneer work. 
Gambusia affinis, the most nearly hardy species, would be the 
best one to try. It probably would not winter successfully any- 
where north of the Mason and Dixon line, but thrives out of 
doors in summer. In the opinion of an experienced aquarist, 
any tropical or sub-tropical aquarium fish can be kept out of 
doors during the summer time, provided that the pond is 
situated in some sheltered and well protected place. 
When fishes, of whatever kind, have been installed, it is well 
to keep an eye out for their natural enemies. Birds may take 
an occasional one, but it is not likely that there will be serious 
depredation from this source. The fish hawk which comes 
up from the South somewhat before its summer food, the 
menhaden, is available off the coast, likes to pick up a big gold-

THE PEARL ROACH OR EUROPEAN RUDD 
Of peaceful inclination, like the goldfish with whom he neighbors amicably, the pearl roach will not molest 
any smaller fry that happen to be about. This makes him a desirable inhabitant of the garden poo!, despite 
a somewhat unfortunate tendency on his part to include Water-lilies and other aquatic plants in his daily diet
