could you explain "color slide" for me~thanks! Introduction to Poetry Billy Collins I ask them to take a poem and hold it up to the light like a color slide *what is "color slide"? or press an ear against its hive. I say drop a mouse into a poem and watch him probe his way out, or walk inside the poem's room and feel the walls for a light switch. I want them to waterski across the surface of a poem waving at the author's name on the shore. But all they want to do is tie the poem to a chair with rope and torture a confession out of it. They begin beating it with a hose to find out what it really means.
