JUNE, 1913, RAILWAY AGE GAZETTE, MECHANICAL EDITION. 307 DRY LUMBER SHED Two papers on this subject were read at the annual meet- ing of the Railway Storekeepers' Association in May. J. W. Gerber of the Southern Railway said in part: The proposed shed is 32 ft. in width and of any desired length, in panels of 12 fl. each. Height from the ground line to plate is 16 ft. 3 in. The posts supporting the building are set on continuous concrete foundations which also serve to carry the stringers on which the lumber is piled. The building is divided into two stories, the lower floor having a clearance of 7 ft. 3 in, the upper floor, a clearance of 7 ft. The galleries on the second Roor level are 4 ft. in width and run the entire length on either side of the building and are reached by stairways at both ends. Both ends of the shed are enclosed, and the overhang is 7 Rafters 21624 'Ctra. entire room. The lumber could, under such conditions, be held ready for use, and need not be again taken to the kiln for drying. The adoption of slate for a roofing material is to be highly recommended, nor only because of the greater saiety, but be- cause of its economy. LAYING OFF SHOES AND WEDGES BY E. T. SPIDY. Assistant General Locomotive Foreman, Canadian Pacific, Winnipeg, Man. At the Winnipeg shops of the Canadian Pacific, the standard practice for lining up and laying off shoes and wedges requires the use of several special instruments.

Push car tracks are provided on either side of the shed, and outside of the push car tracks standard gage tracks are placed for the unloading of car lots of lumber. W. E. Hatter, in his paper, said in part: In the erection of a dry lumber shed the most essential and primary feature to be considered is a scientific system of ventilation, which will permit of the drying and seasoning being thoroughly accom- plished, without in any way endangering the quality of the material contained within the building. This result can be brought about by using a mean between the solid sided building, and an open shed. A building of this type would he su constructed that a space of 2% in. would be leit between the siding boards. They should be set at such an angle, however, that it would be impossible for either rain or snow to beat through, although it would always perrit of a continuous circulation of air throughout the entire building. The feature of nest importance is that of an adequate light- ing system. It is a fact generally understood, that without proper lighting, material is slow to season, and in a great many instances it becomes susceptible to such destructive elements as dry rot, mildew, etc. By the erection of a cupola or second- ary roof, throughout the entire length of the building, the light would be permitted to permeate extensively through the build- ing, which would aid materially the working facilities, and as- sist, as well, in the preservation of the material. Particular stress must be placed upon the proper huilding of a special room, or series of rooms, in which kiln dried material may be stored, and where the conditions produced by the kiln will be retained. To properly procure this result, the room or rooms must be so constructed as to be entirely light, permitting of a series of ventilating pipes on each side of the room, or Tooms. by means of which an average temperature would be obtained, and the installation of two 2 in. steam pipes around the planing the faces, are put in place and supported by the pedestal binders.
