Lizzie made a good-natured grab at the caterpillar, and then there was a cry of pain. "Oh, begorra, begorra, I'm stung by a wasp, I am! Ow!" But she still kept tight hold of the caterpillar as she danced about.

"No," said the guide, "you're not stung by any wasp. Bring me that! There, open your hand. You see, the caterpillar stung you."

"Oh my, what a beauty!" exclaimed the children. "But caterpillars don't sting."

"Oh yes, they do," continued Ben Gile, with a twinkle in his eye; "ask Lizzie." Lizzie was looking at the palm of her hand, which showed how badly it had been stung.

"Now, you see, we'll need something to pick up these little creatures with—a pair of forceps or something of that kind. At least, you must be very careful."

"And what else do we need?" asked the children.

"A little hand lens will magnify the small parts of an insect a great deal. It will show you all the tiny hairs on the body, and the little rings and the feelers and the facets of the eyes, and many another wonderful thing."

"What are we going to put the bugs in?" inquired Jimmie.

"Lizzie will get you a small wooden box," said Mrs. Reece.

Lizzie went off grumbling something about guides and bites and insects, but soon she came back with a nice box, and in a minute all the children's heads were clustered about Ben Gile as he showed them how to line the box with a layer of cork, how to steam the insects a little if they were dry, and then how to put the long, slender pins through the chest of the insect and stick it into the cork.
