Although it has no resemblance to a Bear, the tail part has obvious resemblance to a Dipper, by which name it is known to most Americans. Therefore, because so well known, so easily pointed out, and so helpful in pointing out the other stars, this Dipper will be our starting point and shall prove our Key to the whole sky. If you do not know the Dipper, get some one who does to point it out; or look in the northern sky for the shape shown in Cut, remembering that it goes aroimd the Pole Star every twenty-four hours, so that at different times it is seen at different places.

Now, we have found the great Pole Star, which is called by Indians the "Star that never moves" and the "Home
