plan or with pumps, according to the topography of the site 

 and the elevation of the rooms. The receiving room floor and 

 the platform which accommodates the vacuum pans, should be 

 seven to eight feet above the main floor. In order to take care 

 of storage of water, sugar, tin cans, barrels and box shocks, 

 there should be a second floor over the well room and the filling, 

 sealing and sterilizing room. The ceiling of these rooms should 

 be not less than sixteen feet above the floor. 



The rooms are so arranged as to necessitate the minimum 

 expenditure of machinery, conveyors and labor. All work rooms 

 open on the railway switch, and the storage room is accessible 

 by two elevators. The well room, where most of the steam is 

 needed, is next to the boiler room, so as to minimize condensa- 

 tion in the steam pipes. If the main steam pipes are, properly 

 insulated, this arrangement should furnish the vacuum pans with 

 dry steam. The floor in the boiler room should be two feet 

 below the main floor, in order to give additional fall for the con- 

 densation water from jacket and coils of the. vacuum pans to the 

 boiler feed tank. 



The partition between the receiving room and testing room 

 is equipped with a cabinet, opening on both sides so that the 

 sample bottles can be placed on the shelves in the receiving 

 room and taken off the shelves in the test room. 



From the weigh cans on the receiving platform the milk runs 

 direct into the hot wells, which are sufficient in number to con- 

 veniently divide the milk into batches and to heat the milk with 

 the least possible delay. The capacity of the vacuum pumps is 

 augmented by their close proximity to the vacuum pans and the 

 hot wells and by the fact that the water supply tanks are over- 

 head. The space to be evacuated is confined very largely to the 

 vacuum pan only, the milk has to be lifted by the vacuum pump 

 but a few feet and the water runs into the condenser by gravity. 



From the well room the condensed milk is transferred to the 

 tanks on the platform over the filling machines. The evaporated 

 milk is pumped from the cooling coils through the wall and the 

 sweetened condensed milk is raised to the platform in ten-gallon 

 cans on the elevator, or is forced by a pressure pump into the 

 tanks feeding the filling machines. The sealing benches are 

 equipped with self-heating soldering coppers. In the place of the
