"THERMOS FLASK" MILK TRAIN

Glass-lined steel tanks on the thermos principle are being tried on American milk trains.

Each car is really a gigantic double thermos flask of steel and glass, holding 2.-)00 gallons of milk, which is pumped in and chilled down to a'lout. 40 degrees. There are two such thermos bottles on each car, and between ihe two tanks is an agitator driven by a motor which keeps the contents well stirred.

These tank curs in the Western states arc replacing the hundreds of dairy milk cans which are responsible for a good deal of waste in transport.

In appearance the future milk train "will look something like a series of oiltankers.

Apart from economy, the hygiene and convenience of tbe latest form of milk transportation is obvious, because the glass lining \\_hieh is fused into the metal case at a high temperature is smooth and easily scoured with hot water and soda, and refrigerating facilities are part of the equipment of the cpiv milk train.

Three of these milk-tankers will give the accommodation of seven ordinary caxs loaded "with 10-gallon churns.
