After finding Arcturus  (using the technique described in The Big Dipper, Key To The Night Sky), move to the second brightest star in Bo÷tes which is in the middle of the kite shaped constellation.  From this star moved toward the east a small distance until you encounter a semi-circle of faint stars which outline the constellation Corona Borealis, The Northern Crown.


 Figure 21: June constellations near the meridian.

        Continue your eastward direction and you will see four faint stars arranged in a lopsided quadrangle.  This asterism is known as The Keystone Of Hercules and is the abdomen of the constellation named after Hercules the mythical son of Zeus.  Figure 21 may be used in your efforts to pick out the other stars in this large but rather faint constellation.
