From his shoulder Hiawatha
     Took the camera of rosewood,
     Made of sliding, folding rosewood;
     Neatly put it all together.
     In its case it lay compactly,
     Folded into nearly nothing;
     But he opened out the hinges,
     Pushed and pulled the joints and hinges,
     Till it looked all squares and oblongs,
     Like a complicated figure
     In the Second Book of Euclid.
