A. No. Honey-dew is a sweet liquid shed by a very small insect (called the aphis), and deposited in autumn on the under surface of favourite leaves.

Q. Does honey-dew injure leaves, or do them good?

A. It injures them very much, because it fills the pores of the leaf with a thick clammy liquid; and, therefore, prevents the leaf from transpiring and absorbing.

Q. What effect has honey-dew upon the appearance of a leaf?

A. After a little time, the leaf (being smothered and starved) begins to turn a dingy yellow.

Q. Are not ants very fond of honey-dew?

A. Yes; and they crawl up the loftiest trees, in order to obtain it.

Q. What is the cause of mist (or earth-fog)?

A. If the night has been very calm, a rapid radiation of heat has taken place in the earth; in consequence of which, the air (resting on the earth) is made so cold, that its vapour is chilled, and condensed into a thick mist.
