A PAPER TELESCOPE.

This is probably the largest paper telescope in Great Britain. The body

of the instrument is entirely covered with thick brown paper, its length

being 25ft., and the object glass 12in. in diameter. With this

apparatus, the mountains on the surface of the moon appear with great

clearness. The group represents a family studying astronomy. The girl

standing by the side of the gentleman looking through the telescope

holds a Nautical Almanac in her hand, and is aiding the observers with

details from its valuable records.
