One had but to stand before it and wish to see what any person was doing, and at once a scene would flash upon the magic canvas which showed exactly where that person was, and like our own moving pictures would reproduce the actions of that person as long as you cared to watch them.

So today, when Dorothy tired of her embroidery, she drew the curtains from before the Magic Picture and wished to see what her friend Button Bright was doing.

Button Bright, she saw, was playing ball with Ojo, the Munchkin boy, so Dorothy next wished to see what her Aunt Em was doing.

The picture showed Aunt Em quietly engaged in darning socks for Uncle Henry, so Dorothy wished to see what her old friend the Tin Woodman was doing.
The Tin Woodman was then just leaving his tin castle in the company of the Scarecrow and Woot the Wanderer.

Dorothy had never seen this boy before, so she wondered who he was.
