Tommy, who had hitherto enjoyed all the good things of this life, without reflecting from whom he had received them, was very much struck with the piety of this honest and contented man; but as he was going to answer, the good woman, who had laid a clean, though coa.r.s.e, cloth upon the table, and taken up her savoury supper in an earthen plate, invited them to sit down; an invitation which both the boys obeyed with the greatest pleasure, as they had eaten nothing since the morning. In the meantime the honest man of the house had taken his hat and walked to Mr Barlow"s, to inform him that his two pupils were safe in the neighbourhood.
Mr Barlow had long suffered the greatest uneasiness at their absence, and not contented with sending after them on every side, was at that very time busy in the pursuit, so that the man met him about half-way from his own house. As soon as Mr Barlow heard the good news, he determined to return with the man, and reached his house just as Tommy Merton had finished one of the heartiest meals he had ever made.
The little boys rose up to meet Mr Barlow, and thanked him for his kindness, and the pains he had taken to look after them, expressing their concern for the accident which had happened, and the uneasiness which, without designing it, they had occasioned; but he, with the greatest good-nature, advised them to be more cautious for the future, and not to extend their walks so far; then, thanking the worthy people of the house, he offered to conduct them, and they all three set out together in a very cold, but fine and star-light evening.
As they went home Mr Barlow renewed his caution, and told them the dangers they had incurred. "Many people," said he, "in your situation, have been surprised by an unexpected storm, and, losing their way, have perished with cold. Sometimes, both men and beasts, not being able to discern their accustomed track, have fallen into deep pits filled up and covered with the snow, where they have been found buried several feet deep, and frozen to death." "And is it impossible," said Tommy, "in such a case to escape?" "In general it is," said Mr Barlow; "but there have been some extraordinary instances of persons who have lived several days in that condition, and yet have been taken out alive; to-morrow you shall read a remarkable story to that purpose."
As they were walking on, Tommy looked up at the sky, where all the stars glimmered with unusual brightness, and said, "What an innumerable number of stars is here! I think I never observed so many before in all my life!" "Innumerable as they appear to you," said Mr Barlow, "there are persons that have not only counted all you now see, but thousands more, which are at present invisible to your eye." "How can that be?" inquired Tommy, "for there is neither beginning nor end; they are scattered so confusedly about the sky, that I should think it as impossible to number them, as the flakes of snow that fell to-day while we were in the wood."
At this Mr Barlow smiled, and said, that he believed Harry could give him a different account, although perhaps he could not number them all.
"Harry," said he, "cannot you show your companion some of the constellations?" "Yes," answered Harry, "I believe I remember some that you have been so good as to teach me." "But pray, sir," said Tommy, "what is a constellation?"
"Those," answered Mr Barlow, "who first began to observe the heavens as you do now, have observed certain stars, remarkable either for their brightness or position. To these they have given a particular name that they might the more easily know them again, and discourse of them to others; and these particular cl.u.s.ters of stars, thus joined together and named, they call _constellations_. But come, Harry, you are a little farmer, and can certainly point out to us Charles" Wain."
Harry then looked up to the sky, and pointed out seven very bright stars towards the north. "You are right," said Mr Barlow; "four of these stars have put the common people in mind of the four wheels of a waggon, and the three others of the horses, therefore they have called them by this name. Now, Tommy, look well at these, and see if you can find any seven stars in the whole sky that resemble them in their position."
_Tommy._--Indeed, sir, I do not think I can.
_Mr Barlow._--Do you not think, then, that you can find them again?
_Tommy._--I will try, sir. Now, I will take my eye off, and look another way. I protest I cannot find them again. Oh! I believe, there they are.
Pray, sir (pointing with his finger), is not that Charles" Wain?
_Mr Barlow._--You are right; and, by remembering these stars, you may very easily observe those which are next to them, and learn their names too, till you are acquainted with the whole face of the heavens.
_Tommy._--That is indeed very clever and very surprising. I will show my mother Charles" Wain the first time I go home; I daresay she has never observed it.
_Mr Barlow._--But look on the two stars which compose the hinder wheel of the waggon, and raise your eye up towards the top of the sky; do you not see a very bright star, that seems to be almost, but not quite, in a line with the two others?
_Tommy._--Yes, sir; I see it plainly.
_Mr Barlow._--That is called the Pole-star; it never moves from its place, and by looking full at it, you may always find the north.
_Tommy._--Then if I turn my face towards that star, I always look to the north.
_Mr Barlow._--You are right.
_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.
_Mr Barlow._--Do not you know, Harry?
_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.
_Mr Barlow._--Perfectly right.
_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.
_Mr Barlow._--But how would you do that?
_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?
_Tommy._--That"s true, indeed. My Lord Wimple"s great room that I have heard all the people admire so much, is no more to be compared to it than the shabbiest thing in the world.
_Mr Barlow._--That is indeed true; but there are some, and those very important, uses to be derived from an acquaintance with the stars.
Harry, do you tell Master Merton the story of your being lost upon the great moor.
_Harry._--You must know, Master Tommy, that I have an uncle who lives about three miles off, across the great moor that we have sometimes walked upon. Now, my father, as I am in general pretty well acquainted with the roads, very often sends me with messages to my uncle. One evening I went there so late, that it was scarcely possible to get home again before it was quite dark. It was at that time in the month of October. My uncle wished me very much to stay at his house all night, but that was not proper for me to do, because my father had ordered me to come back; so I set out as soon as I possibly could, but just as I had reached the heath, the evening grew extremely dark.
_Tommy._--And were not you frightened to find yourself all alone upon such a dismal place?
_Harry._--No; I knew the worst that could happen would be that I should stay there all night, and as soon as ever the morning shone, I should have found my way home. But, however, by the time that I had reached the middle of the heath, there came on such a violent tempest of wind, blowing full in my face, accompanied with such a shower, that I found it impossible to continue my way. So I quitted the track, which is never very easy to find, and ran aside to a holly-bush that was growing at some distance, in order to seek a little shelter. Here, I lay, very conveniently, till the storm was almost over; then I rose and attempted to continue my way, but unfortunately I missed the track, and lost myself.
_Tommy._--That was a very dismal thing indeed.
_Harry._--I wandered about a great while, but still to no purpose. I had not a single mark to direct me, because the common is so extensive, and so bare either of trees or houses, that one may walk for miles and see nothing but heath and furze. Sometimes I tore my legs in scrambling through great thickets of furze; now and then I plumped into a hole full of water, and should have been drowned if I had not learned to swim; so that at last I was going to give it up in despair, when, looking on one side, I saw a light at a little distance, which seemed to be a candle and lantern that somebody was carrying across the moor.
_Tommy._--Did not that give you very great comfort?
"You shall hear," answered Harry, smiling. "At first I was doubtful whether I should go up to it; but I considered that it was not worth anybody"s pains to hurt a poor boy like me, and that no person who was out on any ill design, would probably choose to carry a light. So I determined boldly to go up to it, and inquire the way."
_Tommy._--And did the person with the candle and lantern direct you?
