ENIGMA
I am composed of eighteen letters.
My 9-16-2 is that which covers the greater part of the world.
My 3-6-8 is an abbreviation and a title.
My 15-4-12-18 is something from which water is obtained.
My 1-10-15-4-17 is a gem.
My 11-7-13-18 is to quiet.
My 5-14-12-4 is part of a shoe.
My whole is a well known author.
—Edith Irene.
My number, definite and known,
Is ten times ten told ten times o’er;
One-half of me is one alone,
The other exceeds all count and score.
—Selected.
