DR. BARTLETT.

The books of wise writers, are useful to make us more easily understand what we see and experience; but our own eyes may teach us a great deal. The Book of Nature, the heavens, with all the stars and planets; this earth on which we are, with all its productions and creatures, is the best book; but others will serve as guides.

CHARLES.

See, Sir, I think it is lighter.

DR. BARTLETT.

Observe now, how the stars begin to grow dim, before the approaching light of the sun.

WILLIAM.

I thought always that the stars went away, when it was day light.

DR. BARTLETT.

There are some which have their appointed revolutions; and others which are stationary; these we call the fixed stars.
