I have named the seasons when, according to some people, these

constellations are most enjoyable. But these are not the only times when

you can see them. (If you had that seventy-five-cent planisphere, now,

you could always tell which constellations are visible and just where to

find them.) No matter what time of year you read this chapter, it is

worth while to go out and look for these marvels. You can't possibly

miss them all.

Have you ever seen a Sickle in the sky? It's a beauty, and whenever I

have seen it it has been turned very conveniently for me, because I am

left-handed. It is so easy to find that I am almost ashamed to tell. But

if you need help, draw a line through the Pointers backward, away from

the Pole star, about forty degrees, and it will come a little west of

the Sickle. The Sickle is only part of the Lion--the head and the

forequarters. Only fanciful map-makers can trace the rest of the Lion.

The bright star at the end of the handle is Regulus, which means "king,"

from the stupid old notion that this star ruled the lives of men. To

this day people speak of the "Royal Star," meaning Regulus. And at the

end of this chapter I will tell you about three other stars which the

Persians called "royal stars."

Another constellation which children particularly love is the

Twins--Castor and Pollux. But the sailors got there first! For thousands

of years the twins have been supposed to bring good luck to sailors. I

don't believe a word of it. But I do know that sailors gloat over Castor

and Pollux, and like them better than any other stars. The whole

constellation includes all the stars east of the Bull and between the

Charioteer and Procyon. But another way to outline the twins is to look

northeast of Orion where you will see two rows of stars that run nearly

parallel. To me the brothers seem to be standing, but all the old

picture-makers show them sitting with their arms around each other, the

two brightest stars being their eyes. The eyes are about five degrees

apart--the same as the Pointers.

Pollux is now brighter than Castor, but for thousands of years it was

just the other way. It is only within three hundred years that this

change has taken place. Whether Castor has faded or Pollux brightened,

or both, I do not know. Anyhow, Castor is not quite bright enough to be

a first magnitude star. Three hundred years is a short time in the

history of man, and only a speck in the history of the stars. Three

hundred years ago they killed people in Europe just because of the

church they went to. That was why the Pilgrim Fathers sailed from

England in 1620, and made the first permanent settlement in America,

except, of course, Jamestown, Va., in 1607.

There are plenty of stories about old Castor and Pollux, and, like all

the other myths, they conflict, more or less. But all agree that these

two brothers went with Jason in the ship Argo, shared his adventures and

helped him get the golden fleece. And all agree that Castor and Pollux

were "born fighters." And that is why the Roman soldiers looked up to

these stars and prayed to them to help them win their battles.

Now for the four summer constellations every one ought to know. The

first thing to look for is two famous red or reddish stars--Arcturus and

Antares.

The way you find Arcturus is amusing. Look for the Big Dipper and find

the star at the bottom of the dipper nearest the handle. Got it? Now

draw a curve that will connect it with all the stars in the handle, and

when you come to the end of the handle keep on till you come to the

first very bright star--about twenty-five degrees. That is the monstrous

star Arcturus, probably the biggest and swiftest star we can ever see

with the naked eye in the northern hemisphere. He is several times as

big as our sun, and his diameter is supposed to be several million

miles. He is called a "runaway sun," because he is rushing through space

at the rate of between two hundred and three hundred miles a second.

That means between seventeen and thirty-four million miles a day!

He is coming toward us, too! At such a rate you might think that

Arcturus would have smashed the earth to pieces long ago. But he is

still very far away, and there is no danger. Some people say that if Job

were to come to life, the sky would seem just the same to him as it did

3,400 years ago. The only difference he might notice would be in

Arcturus. That would seem to him out of place by a distance about three

times the apparent diameter of the moon.

Some people believe this because Job said, "Canst thou guide Arcturus

with his sons?" and therefore they imagine that he meant this red star.

But I believe he meant the Big Dipper. For in King James's time, when

the Bible was translated into English, the word "Arcturus" meant the Big

Dipper or rather the Great Bear. And for centuries before it meant the

Great Bear. One proof of it is that "Arcturus" comes from an old Greek

word meaning "bear"--the same word from which we get arctic. It is only

within a few hundred years that astronomers have agreed to call the

Great Bear "Ursa Major," and this red star Arcturus. So I think all the

books which say Job mentioned this red star are mistaken. I believe

Webster's Dictionary is correct in this matter, and I believe the

Revised Version translates Job's Hebrew phrase more correctly when it

says, "Canst thou guide the Bear with her train?"

Anyhow, Arcturus is a splendid star--the brightest in the constellation

called the "Herdsman" or Booetes. It is not worth while to trace the

Herdsman, but here is an interesting question. Is Arcturus really red?

The books mostly say he is yellow. They say he looks red when he is low

in the sky, and yellow when he is high. How does he look to you? More

yellow than red?

Well, there's no doubt about Antares being red. To find him, draw a long

line from Regulus through Arcturus to Antares, Arcturus being more than

half way between the other two. But if Regulus and the Sickle are not

visible, draw a line from Altair, at right angles to the Eagle, until

you come to a bright star about sixty degrees away. You can't miss

Antares, for he is the only red star in that part of the sky.

Antares belongs to a showy constellation called the Scorpion. I cannot

trace all the outline of a spider-like creature, but his poisonous tail

or "stinger" is made by a curved line of stars south and east of

Antares. And you can make a pretty fan by joining Antares to several

stars in a curve which are west of Antares and a little north. There is

an old tale that this Scorpion is the one that stung Orion to death when

he began to "show off" and boast that there was no animal in the world

that could kill him.

Another very bright star in the southern part of the sky is Spica. To

find it, start with the handle of the Dipper, and making the same

backward curve which helped you to find Arcturus, keep on till you come

to the white star Spica--say thirty degrees beyond Arcturus. This is the

brightest star in the constellation called "the Virgin." It is not worth

while trying to trace her among nearly forty faint stars in this

neighbourhood. But she is supposed to be a winged goddess who holds up

in her right hand an _ear of wheat_, and that is what Spica means.

Now for an autumn constellation--the Southern Fish. I don't care if you

fail to outline a fish, but I do want you to see the bright star that is

supposed to be in the fish's mouth. And I don't want you to balk at its

hard name--Fomalhaut (pronounced _fo'-mal-o_). It is worth a lot of

trouble to know it as a friend. To find it, you have to draw an

exceedingly long line two-thirds of the way across the whole sky. Start

with the Pointers. Draw a line through them and the Pole star and keep

clear on until you come to a solitary bright star rather low down in the

south. That is Fomalhaut. It looks lonely and is lonely, even when you

look at it through a telescope.

And now for the last story. Once upon a time the Persians thought there

must be four stars that rule the lives of men. So they picked out one in

the north and one in the south and one in the east and one in the west,

just as if they were looking for four bright stars to mark the points of

the compass. If you want to find them yourself without my help don't

read the next sentence, but shut this book and go out and see. Then

write down on a piece of paper the stars you have selected and compare

them with the list I am about to give. Here are the four royal stars of

the Persians: Fomalhaut for the north, Regulus for the south, Aldebaran

for the east, and Antares for the west.

Why doesn't this list agree with yours? Because Persia is so far south

of where we live. Ah, there are very few things that are absolutely

true. Let's remember that and not be too sure: for everything depends

upon the point of view! I hope you will see Fomalhaut before Christmas,

before he disappears in the west. He is with us only five months and is

always low--near the horizon. But the other seven months in the year he

gladdens the children of South America and the rest of the southern

hemisphere, for they see him sweeping high and lonely far up into their

sky and down again.

But the loveliest of all the constellations described in this chapter is

the Northern Crown. It is not a perfect crown--only about half a

circle--but enough to suggest a complete ring. Look for it east of

Arcturus. I can see seven or eight stars in the half-circle, one of

which is brighter than all the others. That one is called "the Pearl."

The whole constellation is only fifteen degrees long, but "fine things

come in small packages"; and children grow to love the Northern Crown

almost as much as they love the Pleiades.

THE TWENTY BRIGHTEST STARS

If you have seen everything I have described so far, you have reason to

be happy. For now you know sixteen of the most famous constellations and

fifteen of the twenty brightest stars. There are only twenty stars of

the first magnitude. "Magnitude" ought to mean size, but it doesn't. It

means brightness--or rather the apparent brightness--of the stars when

seen by us. The word magnitude was used in the old days before

telescopes, when people thought the brighter a star is the bigger it

must be. Now we know that the nearer a star is to us the brighter it is,

and the farther away the fainter. Some of the bright stars are

comparatively near us, some are very far. Deneb and Canopus are so far

away that it takes over three hundred years for their light to reach us.

What whoppers they must be--many times as big as our sun.

Here is a full list of the twenty stars of the first magnitude arranged

in the order of their brightness. You will find this table very useful.

The five stars marked * belong to the Southern hemisphere, and we can

never see them unless we travel far south. Last winter I went to Florida

and saw Canopus, but to see the Southern Cross you should cross the

Tropic of Cancer.

HOW TO LEARN MORE

All I can hope to do in this book is to get you enthusiastic about

astronomy. I don't mean "gushy." Look in the dictionary and you will

find that the enthusiast is not the faddist. He is the one who sticks to

a subject for a lifetime.

Nor do I care a rap whether you become an astronomer--or even buy a

telescope. There will be always astronomers coming on, but there are too

few people who know and love even a few of the stars. I want you to make

popular astronomy a life-long hobby. Perhaps you may have to drop it for

ten or fifteen years. Never mind, you will take up the study again. I

can't expect you to read a book on stars if you are fighting to make a

living or support a family, unless it really rests you to read about the

stars. It does rest me. When things go wrong at the office or at home, I

can generally find rest and comfort from music. And if the sky is clear,

I can look at the stars, and my cares suddenly seem small and drop away.

Let me tell you why and how you can get the very best the stars have to

teach you, without mathematics or telescope. Follow this programme and

you need never be afraid of hard work, or of exhausting the pleasures

of the subject. Go to your public library and get one of the books I

recommend in this chapter, and read whatever interests you. I don't care

whether you take up planets before comets or comets before planets, but

whatever you do do it well. Soak the interesting facts right in. Nail

them down. See everything the book talks about. Make notes of things to

watch for. Get a little blank book and write down the date you first saw

each thing of interest. Write down the names of the constellations you

love most. Before you lay down any star book you are reading, jot down

the most wonderful and inspiring thing you have read--even if you have

only time to write a single word that may recall it all to you. Treasure

that little note book as long as you live. Every year it will get more

precious to you.

Now for the books:

1. _Martin._ _The Friendly Stars._ Harper & Brothers, New York, 1907.

This book teaches you first the twenty brightest stars and then the

constellations. I cannot say that this, or any other, is the "best

book," but it has helped me most, and I suppose it is only natural that

we should love best the first book that introduces us to a delightful

subject.

2. _Serviss._ _Astronomy with the Naked Eye._ Harper & Brothers, New

York, 1908.

This teaches you the constellations first and the brightest stars

incidentally. Also it gives the old myths.

3. _Serviss._ _Astronomy with an Opera-Glass._ D. Appleton & Co., New

York, 1906.

4. _Serviss._ _Pleasures of the Telescope._ D. Appleton & Co., New York,

1905.

5. _Milham._ _How to Identify the Stars._ The Macmillan Co., New York,

1909.

This gives a list of eighty-eight constellations, including thirty-six

southern ones, and has tracings of twenty-eight.

6. _Elson._ _Star Gazer's Handbook._ Sturgis & Walton Co., New York,

1909.

About the briefest and cheapest. Has good charts and makes a specialty

of the myths.

7. _Serviss._ _Curiosities of the Sky._ Harper & Brothers, New York.

Tells about comets, asteroids, shooting stars, life on Mars, nebulae,

temporary stars, coal-sacks, Milky Way, and other wonders.

8. _Ball._ _Starland._ Ginn & Co., Boston, New York, etc., 1899.

This tells about a great many interesting experiments in astronomy that

children can make.

* * * * *

If I had only a dollar or less to spend on astronomy I should buy a

planisphere. I got mine from Thomas Whittaker, No. 2 Bible House, New

York. It cost seventy-five cents, and will tell you where to find any

star at any time in the year. It does not show the planets, however. A

planisphere that will show the planets costs about five dollars.

However, there are only two very showy planets, viz., Venus and Jupiter.

Any almanac will tell you (for nothing) when each of these is morning

star, and when each of them is evening star.

The best newspaper about stars, as far as I know, is a magazine called

_The Monthly Evening Sky Map_, published by Leon Barritt, 150 Nassau

St., New York. It costs a dollar a year. It gives a chart every month,

showing all the planets, and all the constellations. Also it tells you

about the interesting things, like comets, before they come.

Good-bye. I hope you will never cease to learn about and love the earth

and the sky. Perhaps you think you have learned a great deal already.

But your pleasures have only begun. Wait till you learn about how the

world began, the sun and all his planets, the distances between the

stars, and the millions of blazing suns amid the Milky Way!

THE END

[Illustration: THE SKY IN WINTER]

NOTE.--These simplified star maps are not as accurate as a planisphere,

but they may be easier for children. All star maps are like ordinary

maps, except that east and west are transposed. The reason for this is

that you can hold a star map over your head, with the pole star toward

the north, and the map will then match the sky. These maps contain some

constellations that are only for grown-ups to study. The Winter

constellations every child should know are:

AURIGA, the Charioteer

CANIS MAJOR, the Big Dog

CANIS MINOR, the Little Dog

CASSIOPEIA, the Queen in Her Chair

CYGNUS, the Swan

LEO, the Lion

ORION, the Hunter

PERSEUS, Which Has the Arc

TAURUS, the Bull

URSA MAJOR, the Great Bear

URSA MINOR, the Little Bear

[Illustration: THE SKY IN SPRING]

NOTE.--Once upon a time all the educated people spoke Latin. It was the

nearest approach to a universal language. So most of the constellations

have Latin names. The English, French and German names are all

different, but if all children would learn the Latin names they could

understand one another. The Spring constellations every child should

know are:

LEO, the Lion

LYRA, the Lyre

CASSIOPEIA, the Queen in her Chair

SCORPIO, the Scorpion

URSA MAJOR, the Great Bear

URSA MINOR, the Little Bear

VIRGO, the Virgin

[Illustration: THE SKY IN SUMMER]

NOTE.--Every sky map is good for three months, in this way: If this is

correct on June 1st at 10 P.M., it will be correct July 1st at 8 P.M.,

and August 1st at 6 P.M. This is because the stars rise four minutes

earlier every night. Thus, after thirty days, any star will rise thirty

times four minutes earlier, or 120 minutes, or two hours. Children need

not learn all the Summer constellations. The most interesting are:

AURIGA, the Charioteer

CANIS MAJOR, the Big Dog

CYGNUS, the Swan

LYRA, the Lyre

SCORPIO, the Scorpion

[Illustration: THE SKY IN AUTUMN]

NOTE.--This book tells how to find all the most interesting stars and

constellations without maps, but many people prefer them. How to use

star maps is explained under "The Sky in Winter." The Autumn

constellations most interesting to children are:

AQUILA, the Eagle

AURIGA, the Charioteer

CASSIOPEIA, the Queen in Her Chair

CYGNUS, the Swan

LYRA, the Lyre

PERSEUS, Which Has the Arc

TAURUS, the Bull

URSA MAJOR, the Great Bear

URSA MINOR, the Little Bear
