The cover this week shows the colossal Statue of Liberty at New York. Composed three-fifths of iron and two-fifths of copper, the statue weighs 100 tons. An enormous concrete monolith was built to act as a foundation for the pedestal on which the figure stands.
GRAIN FROM OVERSEAS for the flour mills of Great Britain is discharged at the quayside by pneumatic elevators which may be fixed or may be run on rails along the quay. Vacuum pumps in the elevators suck the grain from the ship’s hold through pipes to a large tank known as a receiver. This has a dust extractor fitted. The grain is then stored in silos until it is required for milling.
