also an overflow spout at the top of this bin, discharging into a reserve bin of 24 tons capacity on the first floor. This bin is of frame construction, on a concrete foundation. The reserve bin is connected with the concrete conveyor pit, so that when the bin on the third floor is empty, salt may be taken from the reserve bin for the refilling of the higher bin. The salt is taken from the bottom of the bin on the third platform in carts, and carried to salt boxes of 600 lbs. capacity, located on every third post of the platform, just under the floor of this platform. These boxes are filled from the third floor platform and the salt for cars is taken from the bottom of the boxes by workers on the second floor platform.

Of the platform conveyors, there are two on the first floor platform, extending from each end of the long platform to the working space, with the operating machinery for each located in small frame houses, built on the platform, one each side of the working space. On the second floor platform, there are two conveyors extending from the ends of the platform to the working space, with the operating machinery in frame houses located at each end of the long platform. The third floor platform has no conveyor; the crushed ice and salt on this platform are handled in the carts propelled by man-power. These conveyors are operated by electric motors and can all be run in the same direction, sɔ that it is possible to carry cake ice from one end of the platform to the other. Between the two conveyors at the working space, is a connection platform with ice runs, over which the cake ice is handled by men when traveling from one conveyor to the other.

The ice runs and guides for the gravity inclines and conveyors are of maple and in some cases are metal covered. A deflector is located on the south side of the north operating machinery house, and another on the north side of the south machinery house to keep cakes of ice from going into the machinery if they are left on the conveyor. This ice is stored on the platform temporarily, the conveyor is reversed and the blocks are returned either to the house for storage or placed in the car bunkers.

The electric lighting system in the facilities is so installed that the plant can be operated with the same efficiency at night, as in the day. •

Icing Facilities—Jackson, Miss.

The icing facilities at Jackson, Miss., are used chiefly for icing northbound shipments of fruit and vegetables. As this business increased at this point, it was found necessary to provide more adequate platform space and conveyors than were there originally. Also it was thought advisable to provide better track arrangements and save the time required to switch the cars to and from the old platform.

The manufacturing plant furnishing ice at this station is located to the west of the right-of-way, and the old platform with a stub track each side was located on the wayland close to the property line. This required

a switch engine to handle cars to and from the platform. By the new plan, the train icing platform was made about twice as long as the old, and the location moved to the east, providing train icing tracks on each side of the platform, connected at each end with main tracks, which make it possible to handle the trains direct to the icing platform with the road engines.

The facilities lie north and south and consist of a cross-bar double chain, inclined elevating conveyor, a gravity ice slide across the tracks supported upon a double Howe truss bridge, an elevated ice crusher house, salt storage and handling facilities, a high icing platform, part of which is double decked and having car icing tracks on each side, and platform ice conveyors. This installation, which handles 8,260 tons of ice per year, does not have an ice storage house, as the ice is brought direct from the plant of the manufacturer to the platform, by the conveyors, as needed.

The cake icing platform, which is 13 ft. 3 in. above the rail, 12 ft. wide and 1,652 ft. long, with icing tracks on each side, is of yellow pine lumber construction. The platform, also the roof over it, are supported on 8 in. by 8 in. posts on concrete footings. These posts are spaced 14 ft. apart, and are braced both ways below the platform, with 3 in. by 3 in. plank. The 2-in. plank floor is supported on 3 in. by 10 in. joists, spaced 16 in. apart, which in turn are carried on girders of two pieces of 4 in. by 16 in. timbers, set into the side of the posts. The roof over the platform is ready roofing on 1-in. D & M sheeting, which is supported by 2 in. by 6 in. joists, 20 in. apart, on 2 in. by 10 in. girders, set into the outside face of the posts.

A conveyor located on its center line and extending practically the entire length of the platform, allows cars on either side to be iced. This conveyor is divided into two equal parts with operating motors and machinery located midway between the ends of the platform. It is reversible, so the ice may be conveyed continuously in either direction.

At the north end and under the platform is a salt storage house on a concrete foundation, 42 ft. long and the same width as the platform. This house contains a storage bin 28 ft. by 11 ft. 6 in. and a working space 14 ft. by 11 ft. 6 in. The salt bin has a capacity of 50 tons, and is filled by hand from cars at the side of the bin, through wooden doors hinged at the top.

The salt house is made of 3 in. by 10 in. studs, spaced 16 in. apart and lined inside with 2 in. D & M plank. The outside is covered with drop siding. The floor is made up of 2 in. D & M plank laid on 10 in. by 4 in. strips spaced 16 in. apart, over a subfloor of 2 in. D & M plank on a 3 in. by 10 in. floor, with the joists spaced 16 in. apart. The ceiling joists are 2 in. by 6 in., spaced 16 in. apart; over them are laid 1 in. D & M roof boards, covered with ready roofing. The salt is shoveled by hand from the storage bin into an elevator hopper, in one corner of the working space. The elevator, which is an electric driven chain bucket type, elevates the salt to a two-ton bin above the crusher house floor level, or about 28 ft. above the top of rail.

The ice crusher room is 11 ft. 6 in. wide and 42 ft. long with a 9-ft. ceiling at the low point. The construction of this room is the same as of the icing platform as to joists and girders, but the floor is made up of two layers of 2 in. D & M plank with one layer of ready roofing paper between. The floor pitches to the west, on which side are three floor drains connected to a drain pipe which discharges the water upon the ground below.

The walls of this room are made of 2 in. by 6 in. studs, spaced 24 in. apart with 1-in. D & M sheeting on each side, the outside of the wall

being finished with siding with one layer of tarred felt between the sheeting and the siding. The space between the wall studding is filled with burnt granulated cork from the floor to the ceiling. All of the windows have double sash and the doors are insulated cold storage doors, and were manufactured by the Stevenson Cold Storage Door Company. The ceiling is made up of two layers of 1-in. D & M boards with one layer of tarred felt between, which are nailed direct to the roof joists. The roof joists are 2 in. by 8 in., spaced 20 in. apart, and are supported by a continuous plate which is carried on the wall studding. The roof boards
