The engine room is very large and is supplied with abundance of air, light and ventilation, which is a special re- quirement for the heat experienced in the St. Lawrence river during the summer months. The deck auxiliaries consist of one 9 in. by 18 in. bow winch situated on a flat under the main deck with special lead for chains through a hatch on the upper deck, the drum of the winch is designed to accommodate 4,000 ft. of 1% in. steel wire rope and 300 ft. of 11%4 in. chain. One 9 in. by 16 in. stern winch, and two 9 in. by 16 in. breasting winches. The breast- ing winches have drums arranged to handle the port and starboard wires and each winch is capable of accom- modating 4,000 ft. of 1% in. wire rope and 300: ft... of 134. in.. chain cable.

The engine is of. the vertical type, with two cylinders 14% in. diameter by 13 in. stroke, and like the deck auxiliaries, operates with steam at 90 lbs. The hoisting rope is of special plough steel 134 in. diameter, and the drum on the hoisting engine has been made large enough to accommodate all the rope without riding. In ad- dition to the main hoisting rope steel wire preventers 244 in. diameter are fitted to each side of the bucket lad- "POWERFUL BUCKET DREDGER BUILT FOR THE DOMIN CO., COI.LINGWOOD. ONT.

The hoisting sheaves are cast steel 4 ft. 6 in. diameter, specially arranged to take the above cable, the bottom and top blocks having five sheaves each, while a special idler sheave is fitted on the top of the bow shear legs. These shear legs and the main framing have all been specially de- signed to take care of the heavy strains which come on them owing to the massive design of the bucket ladder and the other dredging gear. A winch 6 in. by 8 in. has been in- stalled on the port side to handle the side chute. One side chute only. has been fitted in, the meantime, but ar- rangements have been made so: that in the event of the vessel having to dis- charge on the starboard side, a chute could readily be installed. For hand- ling barges two 8 in. by 8 in. 'cap- stans have been installed on the main a
