There

can

hide

a

by

having

the

letters

For

example

，the

letters

of

“My

elephant eats too many eels” spell out the hidden message “Meet me.”

．

(r

way

to

hide

a

is

to

use

symbols

letters

substitute

number

the

of a real code

，

you must have a code book.39.( a code book

，

you might write

For

example

，“bridge”

stand

for
