These vintage glass fishing net floats were attached to the top of the net while lead weights were used to hold the lower end of the net down in the water. They would string out a long section of the netting to trap fish. The netting would be formed into a round circle, or pulled on to the beach so the trapped fish could be sorted. This float is 12 inches wide with a circumference of about 42 inches. The glass is free of any cracks or holes. The rope has a loop on the top that can be used for suspending the float. Because of the knotting of the rope, the ball will sit in an upright position and not roll around.  A pontil on the bottom of the float indicates it was hand blown.
