With the wax and other patterns in position, a sheet iron mold box was placed around them and packed with a mixture of 1-3 fire clay, 1-3 ground fire brick, and 1-3 fire sand, provisions having been made _ for leaving a small hole at the bottom of the mold to permit of the escape of the heated wax. This opening was also used as a means of preheating the broken sections previous to pour- ing the Thermit steel, the flame of a powerful gasoline torch being directed into it and so permitting of the hot gases passing directly over the frac- tured parts, and so out through the riser. While the parts were being heated a crucible containing 260 lbs. of Ther- Hut, 50. lbs. of soft mild. steel punchings and 5 lbs. of carbonless metallic manganese was placed in position above the pouring gate, and, as soon as the parts to be welded had been brought to a red heat (in about two hours), the hole at the bottom was plugged up with a dry sand core, and the Thermit in the crucible ignited. The ensuing chemi- cal reaction lasted about half a min- ute, then the superheated thermal steel was tapped into the hole, where it filled the space originally occupied by the wax. The mold box was allowed to stay in position over night, in order' to permit of a thorough annealing of the weld. Upon its removal in the morn- ing, it was found that perfect amal- gamation had occurred between the Thermit steel and the metal of the stern post, much to the satisfaction of the officials of the boat and of the ship yard. The weld was performed under the personal direction of G. E. Pellissier, engineer of the Goldschmidt Thermit Co. of 90 West street, New York City, and H. C. Fletcher, of the same company. The Atlantic Works, East Boston, Mass., will soon launch the steam- boat Betty Alden for the Nantasket Steamboat Co. She will be launched -by Miss Betty Alden, a lineal descend- eat of John and -Priscilla: Alden, whose names have been perpetuated in Longfellow's poem. The Hudson Bay Co. has let the contract for the construction of two stern-wheel steamers for its Skeena river service. The hulls will be built by Alex Watson, Victoria, B. C., and the Polson' Jron Works, Toronto, Ont., will buiid the machinery. The vessels will cost about $80,000. 'TAE Marine REVIEW LACKAWANNA TERMINAL NEW YORK.

This will unquestionably be the most powerful light ever produced from a single fixture, and from its position on the upper part of the descent lamps, the whole forming a striking picture from the river. The most impressive feature of the exterior of the station, however, and one which will make the tower the most conspicuous object at night on the LOWER CABIN OF LACKAWANNA FERRYBOAT BINGHAMTON. tower, will illuminate a considerable stretch of the Hudson river. Besides being a most impressive spectacle, this experiment will prove of no lit- tle commercial value in demonstrat- ing the possibility of lighting large
