Feed them and observe their interesting habits. Spiders may be found in attics, cellars, sheds, and barns, on garden flowers, on fences and old walls, under stones and boards, under the bark of decaying logs, etc. In these places will also be found small, round masses of eggs wrapped in silk cocoons. These also should be gathered and allowed to hatch out in the school.
