The first launching at the yard was a scow for the Great Lakes Dredge & Hock -Co., 1/2 it, long, 37 ft.- beam and 13 ft. deep with 10 pockets. This scow is of 1,000 yds. capacity, and is of exceptionally strong construction. The hopper bulkheads are 5£-in. plat- ing and the balance %-in. The doors are operated by power. The _ bulk- heads are closely pitched to make the scow practically unsinkable. The par- titions in the hopper are double plated or of box shape filled in with oak. The partitions when finished will be 7 in. thick. The coamings are stiffened with 12-in. oak timbers, which make the scow's upper works so strong that it would be impossible to make them unfair by any possible abuse. A du- Fic. tug was under repairs at the Whalen yard, but the workmen concluded that better dispatch could be had if the work was actually done at the dry dock plant and so the floating dock with its burden was towed to the ship yard. Sixteen plates were taken off the ice breaker. The rudder was re- paired and a new wheel installed. Fig, 4 shows the Neepawah in dry dock before the launching, which gives a good idea of the size of the dry dock. Fig. 5 shows the punch shop and mold loft and the bow of the Dunelm in dry dock.
