Hiawatha's Photographing

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.

This he perched upon a tripod -
Crouched beneath its dusky cover -
Stretched his hand, enforcing silence -
Said "Be motionless, I beg you!"
Mystic, awful was the process.
