used in unloading blocks of ice from cars into the storage rooms, and the platforms on east side of house, next to the high platform, are used for moving the ice either into the storage rooms or from the house to the conveyor.

Electrically operated conveyors along east side of the building at first floor level, move the ice from the receiving gravity incline at south end of the house, to the ante-room doors, or to the incline elevating conveyor, at the crusher room. The operating machinery for this low level conveyor is in a house under the high platform, and that for the

incline elevating conveyor is in the crusher house. On the elevated train icing platform is a conveyor 980 feet long, with the operating machinery located in a house at south end of the platform.

Manufactured ice is delivered in cars to either ante-room, on west side of the house, where the blocks are taken from the cars and stored in the house by hand. The cars can also be unloaded on the platform at the south end of the building and ice sent by a gravity incline to the low levels conveyor, which delivers the ice either to the ante-rooms or the crusher room.

After the block ice arrives at the crusher house, it can either be crushed and delivered to the cars of a train in carts from the elevated train icing platform, or the cake ice can be delivered by conveyor on

the high platform, alongside of a train to be iced, when the ice is taken from the conveyor by men and placed in the compartments of refrigerator cars. A deflector is located on the north side of the operating machinery house, to prevent cakes of ice from going into the machinery, if left on the conveyor, and this ice is stored temporarily on the platform and later returned by conveyor for storage in the house, or delivery to the cars. The ice runs and guides for the gavity inclines, and conveyors, are made of oak, and in some cases are metal covered. The electric lighting system of the facilities is so arranged that the plant can be operated with the same efficiency at night as in the day time.

Icing Facilities-Waterloo, Iowa.

These icing facilities are used for eastbound shipments of meat and packing house products from South Omaha, and also for fruits and vegetables from California. While some westbound shipments require icing at this station, those eastbound are much greater.

Originally the icing of cars at this point was done at a platform about 600 ft. long, located at the side of an ice storage house of 1,500-ton capacity. The method of handling the ice at this old platform and ice house was crude and entirely inadequate to meet the demands on the plant, as the perishable shipments in both directions through this station increased. The cake ice was handled into and from the house, by means of block and tackle and delivered to cars standing at the platform on run-ways, the ice being moved along the run-ways by man power. If crushed ice was required, the blocks of ice were broken in a large wooden box or bin, by means of wooden mauls handled by laborers. To meet the demand for men to operate the plant at the time of icing a train of cars, it was necessary to call on trackmen or any other labor that was available.

To provide modern methods at this plant, and save a large part of the time required for cars standing at the platform, the house and platforms were rebuilt and enlarged, installing electrically operated mechanical conveyors, elevators and crushers, with provisions for handling both block and crushed ice. This facility, built in 1917, consisted of a 10,000 ton ice storage house, with salt storage bins, a crusher room, elevating and lowering machinery, electrically operated conveyors, gravity inclines, skids, a double deck train icing platform and tracks. The house was made 57 ft. 6 in. wide and 280 ft. 10 in. long with a ceiling height of 35 ft. Half way between the ends of the building is a working space, which is 29 ft. 6 in. by 57 ft. 6 in. and the full height of the building, dividing the building into two separate storage rooms. This working space has three floor levels to match the different icing platform levels at the side of the building, which parallel the icing tracks.

The foundation of the house, footings for posts, and the floors of the storage rooms are concrete. The superstructure is of cypress and

yellow pine timbers construction. The removable sectional floor in the two storage rooms and the siding and all outside trim are cypress lumber. All other lumber is yellow pine.

The foundation walls of the house are concrete 15 in. thick and 8 ft. high. The exterior face of these walls is covered with Wesco Fiberkots, an asphalt, asbestos fibre waterproofing paint, while the interior face of the wall is furred with 2 in. by 4 in. pieces, spaced 24 in. apart. These in turn are covered with two layers of 1 in. by 6 in. D & M sheathing, with one layer of tarred felt paper between them, the first layer of sheathing being laid diagonally. The space caused by the furring strips is filled with granulated cork.

The concrete floor of the storage rooms, which is 5 ft. below the ground, slopes to a trough in the center of the room, running longitudinally and connecting with floor drains, which in turn connect with a gravel basin and then with the sewer. On the concrete floor is placed a super-floor of 2 in. by 6 in. cypress plank with a 1 in. space between, on 4 in. by 4 in. sleepers, spaced 24 in. apart.

The walls of the buildings are made up of 6 in. by 10 in. posts 18 ft. apart, supporting the roof trusses; and 3 in. by 10 in. studding, spaced 24 in. apart. The inner side of the studding is covered with two layers of 1 in. by 6 in. D & M sheathing with one thickness of tarred felt paper between, the first layer of 1 in. by 6 in. sheathing being placed diagonally. The outside face of the studding is covered with one thickness of 1 in. by 6 in. D & M sheathing, laid diagonally, and then with one thickness of tarred felt paper which is covered with siding for the finished wall. The space between the studding for a height of 10 ft. above the foundation wall is filled with burnt granulated cork, the remaining height to the roof being filled with fine wood shavings.

Framed wood trusses supported on 6 in. by 10 in. posts in the side walls carry the roof, which is made up of 8 in. by 10 in. purlines, and 2 in. by 6 in. joists spaced 24 in. The top and bottom sides of the roof joists are ceiled with 1 in. sheathing, the covering for the roof boards being prepared roofing. The space between the wall plate and the under side of the roof boards is left open and covered with No. 20 galvanized wire, 1⁄2 in. mesh, for ventilation and air insulation against sun action. On the center of the roof, extending the full length of the building, is a monitor 2 ft. wide and 3 ft. high, with louvers in each side covered with No. 20 galvanized iron wire of 1⁄2 in. mesh.

The first floor of the "working space" is of cinders, and is at the same elevation as the surounding ground. This floor is used in filling the house with ice received from the platform conveyor on the northwest or from motor trucks on the northeast, this ice being sent to elevating and lowering machines on the north or south side of the working space, by means of a set of gravity slides and switches.

The second floor of the "working space," which is 13 ft. 3 in. above the top of rail of the icing track, is made up of 2 in plank on 3 in. by 10 in joists, 12 in apart, which are carried on 10 in. girders, resting on oak
