The phenomenon observed usually in connection with the spawning of fish, at the distance of four leagues from shore. The water appears to be saturated with a thick jelly, filled with the ova of fish, which is known by its adhering to the ropes that the cobles anchor with while fishing, for they find the first six or seven fathom of rope free from spawn, the next ten or twelve covered with slimy matter, and the remainder again free to the bottom; this gelatinous material may supply the new-born fry with food, and protect them by clouding the water.
