You can
create all sorts of messages by putting the same words together in different
ways. Some kids paint fine. Some fine kids paint. Paint some fine kids!
Animals give messages to one another too. Without words, how do they
do it? Some use scents, not sounds. For instance, tropical tree ants
make ten different kinds of smells. They combine the smells in various
ways, like words in a sentence. Different mixtures give information
about nests, food, and enemies. How brilliant!
