is and if possible
get that for them.

If your fish seem sickly, give them a five-minute bath in salt water
every day for a week. The kind of an aquarium above described is
intended to fill an entirely different purpose from the usual gold
fish globe. In your excursions you will find all sorts of queer
looking eggs and specimens. Some of the eggs are so tiny that they
look almost like black or white dust on the water. Another kind will
be a mass like a jellyfish with brown dots in it, still others will be
fastened in masses to the under side of a leaf in the water or perhaps
on the bottom. What are they? That is just the question and that is
why you will carefully collect them and take them home to await
developments.

Always keep an accurate note-book with dates and facts. Also keep a
close watch on your specimens. Sometimes they will hatch and be eaten
by the other bugs before you could read this chapter.

A nature student will need some part of the house that he may call his
very own. Here he can keep his specimens, his aquarium, his herbarium
and what not. Around the wall he can hang the twigs with their
cocoons, oak galls, last year's wasp and bird nests and other
treasures. He should also have a work table that a little glue or ink
will not injure and a carpet that has no further use in the household.
Usually one corner of the attic or cellar is just the place.

See to it that you do not make other people uncomfortable in the
pursuit of your hobby. You will find that almost every one is afraid
of bugs and toads and that most people live in a world full of
wonderful things and only see a little beyond the end of their noses.

There is a very practical side to nature study and the principal way
that we can make it really pay, is to know our friends from our
enemies in the animal and insect world. There are insects that chew,
suck and bore to ruin our orchards and grain crops. They are our
enemies. If we know their life story, where they hide and how they
breed, we can fight them better. For every dollar's worth of crops
that a farmer grows, it is estimated that his insect enemies eat
another dollar's worth. A little bug called the "San Jose" scale has
nearly ruined the orchards of some of the Eastern states. To fight
him, we must know how he lives. That is nature study. By study we
learn that the hop-toad is our best garden friend. He will spend the
whole night watching for the cutworms that are after our tom
