The other species are of good quality, but owing to their scarcity in this area, have little commercial importance. METHODS OF THE DUNVILLE MUSSEL FISHERY. On my visit to the fishing grounds at Dunnville I found two gangs of men at work on the river above the town; one at a distance of about two miles, and the other some five and one-half miles farther on, near Morgan's island. In the former locality they had a pile of shells which would weigh about five tons. These were fished and shelled in about three and one-half days, by two men and two boys. The men did the fishing, while one boy ran the gasolene launch and the other removed the meat from the shells. The outfit for procuring the clams consists of tw^o scows fastened rigidly together by a plank at each end. The distance between the scows is 4 or 5 feet. The men stand on the stern plank while operating the scoops. The scoop, or dip-net is a dipper-like apparatus with a handle of from 12 to 18 feet in length. The bowl consists of a wire cage about 16 inches in depth, and is attached to a triangular iron frame, 16 inches to a side. Thus the opening of the scoop is triangular and works in the manner of a dredge. To assist in the raking of the beds by this scoop, a number of iron spikes about 3 inches long are fastened to the lower part of the triangular frame, and are set about 3 inches apart. This helps to draw the scoop into the river shown and are set about 3 inches apart. This helps to draw the scoop into the river bed. A line passes from the lower end of the scoop to the forward plank and this is of such a length as to allow the handle to stand vertically against the stern plank. The whole outfit is towe
