These holes are so placed for the purpose of stopping the wheel from revolving, if deemed desirable, by shoving a key through the prong of the iron into any one of the holes that chauces to be uppermost. A large shackle, one end of which is connected with the wheel by the axle bolt, comes in front of the wheel, and from this and the shackle at the top of the iron extends a short chain span that connects with a shackle at its end, to which also the bridle is attached. The following are some details of the measurements: Total height, 3 feet 1 inch: diameter of wheel, 114 inches; thickness of wheel, 5 inches; size of iron between wheel and beam, 1A by l.\ inches; hole for beam iron, If by g inches; lower part of foot is quite flat, Z\ bj jj inches; lower chain bridle, from axle of wheel, 1! feet 8 inches; upper bridle, 1 foot 10 inches. In this ease a Hat bar of iron is tittedinto the end of the beam (which is banded to prevent its splitting), and this iron, projecting beyond the beam, slips into an oblong hole at the upper part of the Fig. X\. Dutch trawl-head. The trawls ordinarily used by the bomschuiten have some peculiari- ties. The following is a description of oneof these trawls, exhibited at London, 1883: The beam is made of soft wood. 25IJ bet long, 3jj inches in diameter, backed by a square iron bar ;,! inch square, which is seized to the beam. Projecting from the beam ends ate iron bats which pass through the holes in the top of the head-irons. The head-iron is .". feel high ; it is straight, small at the top, but with a heavy square toot that is 1<» inches high and 4 inches square, rounded on the lower front part so that it will slip over the bottom.
