Minneapolis, Minn. The Minneapolis Steam Company is being organized and has applied for a franchise to pipe steam through the streets of the city. The project has aroused considerable interest on the part of the civic organizations of the city. At a meeting of the Minneapolis Civic Improvement Association, a letter was read from H. C. Kimbrough, Western manager of the American District Steam Company, explaining the company's proposition. It is expected that a number of public hearings will be arranged before definite action is taken.

Des Moines. Ia.-The heating franchise asked for by the Des Moines Electric Company has been favorably acted upon by the city council and March 26 was set as the date for a special election on the proposition. The Des Moines Electric Company and the city were each to bear half the cost.

Price, Utah.-A proposal has been made by J. H. Manson to the city council of Price to operate the local municipal light plant for 25 years and as rental to pay off the $25,000 bonds with interest. In addition Mr. Manson asks a franchise for the laying of steam pipes in the business district of Price for supplying heat to business blocks and other buildings, including the court house, school house and tabernacle.

Salt Lake City, Utah.-The franchise asked for by the Utah Power & Light Company for the establishment and maintenance of a central heating plant has been granted by the city commission. The franchise is dual in form, being really two franchises. By one, permission is granted to establish a steam heating plant and give service to any part of the city. By the other, the privileges as to heating service formerly held by the Utah Light & Traction Company are transferred to the Utah Power & Light Company. The purpose of the power company is to engage in the furnishing of steam heat over as wide an extent of the city, as may practicable. To this end various heating plants in the business district will be connected and unified with those already operated in conjunction under the old franchise of the Utah Light & Traction Company. One of the first moves to this end was the purchase by the Utah Power & Light Company of the power plant of the two large Newhouse buildings-the Newhouse and the Boston-which recently changed hands. This plant served these two buildings, as well as the Newhouse Hotel, the Commercial Club and other ad

joining buildings. The power company is planning to make the Church heating plant the center of its heating system, with the Newhouse plant as an auxiliary. A 20-in. main will be laid south through the center of the blocks, between Main and West Temple Streets, from South Temple to the Kearns Building and thence to the Newhouse Hotel, thence east to the auxiliary plant and north through the centers of the blocks between Main and State Streets to South Temple Street, forming a rectangle. These mains will act as feeders for branches in various directions. Mayor Ferry was authorized to enter into a 10year contract with the power company for power to operate the pumping plant at Utah Lake, in which the city is interested.

Each time the sand runs through the hour glass at the plant of the B. J. Johnson Soap Co., Milwaukee, Wis., 14,400 cakes of Palmolive soap are producedfour cakes a second, 240 cakes a minute, 14,400 cakes an hour for every working day. This remarkable output is due, in no small measure, to the elaborate arrangements for conditioning the air on the three upper floors of the solid concrete structure that serves both as the company's factory and general offices. The three floors supplied by the system are occupied by the gneral offices. There is also a branch duct leading to the lunch room on the fifth floor.

The balance of the factory is heated with exhaust steam and direct radiation. Every effort has been made to reduce to a minimum waste spaces throughout the building and to this end the hollow supporting columns have been utilized as fresh air ducts. The designers have even gone a step further in having the distributing ducts run along the roof to the hollow concrete columns. This required careful insulation of the roof ducts, as shown in the accompanying illustrations.

With this arrangement of air supply no floor space is used for radiators on the three upper floors.

Another departure from the usual is to be noted in the exhaust system. The

used air is carried by its natural tendency to rise through ducts with openings near the floor line. This system is supplemented in the summer time by dampers, set in the skylight on the top floor. These dampers must be kept closed in winter when the fan is pumping hot air, as otherwise they would interfere with the circulation. In the summer, when the air from the fan is cooled by the air washer (the heating coils being turned off) the used air is the warmer and tends to rise and bank in the skylight. In warm weather, therefore, the double exhaust through both ducts and dampers add considerably to the flexibility and efficiency of the system.

The fan and air washer equipment is located on the roof of the building. It includes a Sirocco engine-driven fan having a capacity of 19,000 cu. ft. of air per minute. The heater is made up of a tempering coil containing 570 sq. ft. of Vento radiation and a reheating coil containing 1,140 sq. ft. of Vento radiation. The fan is driven by a vertical center-crank 6 in. x 5 in. engine. The water for the air washer is circulated by a small motor.

There have been one or two changes made since the original installation was completed. It was found that some form of local adjustment was necessary on the outlets, as some employees preferred

were met with, and sheet metal forms were constructed in advance and anchored into place in the wood forms previous to the pouring of concrete. Before pouring concrete these metal forms were filled with dry sand which was allowed to run out after the concrete was

set.

The construction of the roof duct did not offer any particular difficulties, and was carried out exactly in the manner indicated by the drawings.
