Look ahead of you: when did you ever see an Ar- 
chimedean screw more beautifully marked out than by 
that group of bubbles? They are very light, indeed, 
and seem thus gracefully to struggle into the upper

for insects for food. To those bubbles the arrow-fisher- 
man hastens for game; they are made by the fish that 
he calls legitimate for his sport. 
In early spring the fish are discovered, not only by 
the bubbles they make, but by various sounds, uttered 
while searching for food. These sounds are familiar-

Fish thus exposed are in groups, and are called a
