The Water-Telescope.
85

Any tinner can, at a moderate cost, make an instrument like the one just described.

A water-telescope will add greatly to the entertainment of a boating party or picnic, furnishing a new and novel feature that will become popular wherever it is introduced.

Mr. Fred. Holder tells me that while collecting marine animals with his father, Dr. Holder, the naturalist, they had a boat built with a glass in the hull, arranged and worked upon the same principle as a water-telescope. It was of great service where the water was not too deep. While one person rowed the other watched the bottom, which Mr. Holder describes as having the appearance of a beautiful panorama passing beneath him. Fish of all colors and forms filled the intervening space, and sometimes a "devil fish" would cross the scene, flapping its great wing like fins as it flew rather than swam through the clear water.
