10. Have you ever seen the little wax balls on the tubes of the plant-lice? If so, did you note when and why they were produced?

11. Have you ever seen an ant attacking the enemies of plant-lice? Describe.

12. How do you think this relation of ants to aphids affects agriculture?

13. Study what the ants do for the aphids which infest your rose bushes. Do you infer from this that it is well to exterminate the ant colonies in your flower garden?

LEAFLET XXII.
THE BIRDS AND I.[29]
By L. H. BAILEY.

The springtime belongs to the birds and me. We own it. We know when the Mayflowers and the buttercups bloom. We know when the first frogs peep. We watch the awakening of the woods. We are wet by the warm April showers. We go where we will, and we are companions. Every tree and brook and blade of grass is ours; and our hearts are full of song.
