Lesson 2-1 Spare that spider
Why, you may
wonder, should spiders be our friends? Because they destroy so many insects,
and insects include some of the greatest enemies of the human race．Insects would make it impossible for us to
live in the world; they would devour all our crops and kill our flocks and
herds, if it were not for the protection we get from insect-eating animals．We owe a lot to the birds and beasts who
eat insects but all of them put together kill only a fraction of the number
destroyed by spiders．Moreover, unlike some of the other insect eaters, spiders never do the
least harm to us or our belongings. Spiders are not insects, as many people
think, nor even nearly related to them．One can tell the difference almost at a glance, for aspider always has eight legs and an insect never more than six.
