HIAWATHA'S PHOTOGRAPHING.
69
Till it looked all squares and oblongs,
Like a complicated figure
In the second book of Euclid.
This he perched upon a tripod,
And the family in order
Sat before him for their pictures.
Mystic, awful was the process.
First, a piece of glass he coated
With Collodion, and plunged it
In a bath of Lunar Caustic
Carefully dissolved in water:
There he left it certain minutes.
Secondly, my Hiawatha
Made with cunning hand a mixture
Of the acid Pyro-gallic,
And of Glacial Acetic,
And of Alcohol and water:
This developed all the picture.
Finally, he fixed each picture
