_Tommy._--Then if I turn my face towards that star, I always look to the north.
_Tommy._--Then I shall turn my back to the south.
_Mr Barlow._--You are right again; and now cannot you find the east and the west?
_Tommy._--Is it not the east where the sun rises?
_Mr Barlow._--Yes; but there is no sun to direct you now.
_Tommy._--Then, sir, I cannot find it out.
_Harry._--I believe, sir, that if you turn your face to the north, the east will be on the right hand, and the west on the left.
_Tommy._--That is very clever indeed; so then, by knowing the Pole-star, I can always find north, east, west, and south. But you said that the Pole-star never moves; do the other stars, then, move out of their places?
_Mr Barlow._--That is a question you may learn to answer yourself, by observing the present appearance of the heavens, and then examining whether the stars change their places at any future time.
_Tommy._--But, sir, I have thought that it would be a good contrivance, in order to remember their situation, if I were to draw them upon a bit of paper.
_Tommy._--I would make a mark upon the paper for every star in Charles' Wain; and I would place the marks just as I see the stars placed in the sky; and I would entreat you to write the names for me; and this I would do till I was acquainted with all the stars in the heavens.
_Mr Barlow._--That would be an excellent way, but you see a paper is flat; is that the form of the sky?
_Tommy._--No; the sky seems to rise from the earth on every side, like the dome of a great church.
_Mr Barlow._--Then if you were to have some round body, I should think it would correspond to the different parts of the sky, and you might place your stars with more exactness.
_Tommy._--That is true, indeed, sir; I wish I had just such a globe.
_Mr Barlow._--Well, just such a globe I will endeavour to procure you.
_Tommy._--Sir, I am much obliged to you, indeed. But of what use is it to know the stars?
_Mr Barlow._--Were there no other use, I should think there would be a very great pleasure in observing such a number of glorious glittering bodies as are now above us. We sometimes run to see a procession of coaches, or a few people in fine clothes strutting about. We admire a large room that is painted, and ornamented, and gilded; but what is there in all these things to be compared with the sight of these luminous bodies that adorn every part of the sky?
