STOEY of the fly 
27 
In the summer time the eggs hatch into maggots after four or 
five hours, and in about three days the maggots become full grown 
and change into pupae, which are a sort of chrysalis. In the chrysalis 
is formed the body of the new fly, which emerges after a period of from 
three to five days. Many eggs are laid in the autumn, but these eggs 
do not develop and hatch during the winter, as the cold causes the 
undeveloped flies to stop growing. Some of these exist throughout 
the winter, and begin growing when the warm days of spring come. 
Do Flies Grow? 
When the winter is past and the warm weather returns, the fly 
inside the chrysalis begins to grow again. At the right moment it bursts 
open its brown, horny case, and comes out. All that it has to do then 
is to dry its wings, after which it can fly away full-grown. When we 
see small flies and large flies together, we must not get the idea that 
the small ones are young and the large ones old. They are different 
sorts of flies, 'but are full-grown. 
A Day in the Life of a Fly 
We will now picture a day in the life of a fly. Watcli his travels. 
From the garbage can he takes his rounds into all the unclean places 
in the neighborhood. After he has gotten liis legs and body covered 
with filth laden with disease-germs, he arrives at the dinner-table, and 
worst of all, he crawls upon the baby’s bottle and upon its sweet face, 
leaving his deadly disease-germs wherever he crawls, and causes baby’s 
death. The last of our picture tells the saddest story—which is true of 
thousands of babies throughout the United States each year. 
Nothing is too dirty of bad for a fly to eat, and he will carry this 
filth right into the kitchen and dining-room, and upon your eatables 
if you let him. 
Swat the Fly 
As the fly is one of the worst agents through which disease is 
spread, it is well that we do all we can to kill his kind. And the best 
way to’get rid and stay rid of flies is) through cleanliness. 
In many places school-teachers are explaining to the pupils the 
necessity of killing as many of the flies as possible, and destroying 
their breeding-places. That the fly is a pest which carries filth and
