y followed him down the garden walk. On reaching the fig tree, Mr.
Harvey saw that nearly all its leaves had been eaten off, with most of
the bark and young branches. Thomas and Samuel were very sorry, and John
said he would kill every locust he met, from that day forward. Mr.
Harvey examined the tree, and found, that although much damage had been
done to it, yet with proper care, it might be restored. "We ought to
have covered it with a net," he said to the boys.

While his father was talking with Thomas and his cousin, John was
stooping on the ground, hammering something with a stone. At last Mr.
Harvey turned round, and asked John what he was doing.

"I am killing these fine locusts that I have caught," replied John.

"Stop, my son," said Mr. Harvey, "that is foolish conduct, and very
wicked. You are giving way to anger and revenge, two of the worst
passions that a youth can indulge."

"But, father, they will eat more trees."

he would send a servant to place a screen over it. When they came to the
house, John reminded his father of his promise concerning the locusts.
Mr. Harvey took from a shelf several large pictures of insects, and
laying one on the table, asked his son what he thought it was.

"It looks like a large grasshopper," said John.

"It is the locust of the East," replied his father. "These locusts are
shaped almost exactly like the long-winged grasshoppers that fly about
our fields; but they are two or three times larger. What do you think
this picture is?"

"It seems to be a great cloud of dust."

"It is a swarm of Eastern locusts. Hundreds of thousands fly thus
together, darkening the air, and driving every thing before them. When
alighting they cover the earth for more than a mile round, and eat every
green thing to the very roots. The noise of their wings is like thunder.
They leave the country like a desert, so that the terrified people look
forward to misery and famine. Men, women, and children, turn out w
