other 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
