The pressure of a diamond-pointed hammer on a steel part makes an indentation that tells the metallurgist how hard that piece of sicel is. This is one of the many tests in the modern auto plant's metallurgical department.

The low prices which have made Hudson and Essex famous havo largely been achieved through the simple process of using inventory materials quicker, and getting a greater output from plant machinery than is commonly done in 'Industry. Mechanical conveyance of materials has been developed to an unusual degree. So quickly are materials consumed in the unusually efficient manufacturing processes of the Hudson Motor Car Company, that the public actually goes riding in Hudson and Essex cars before the commitments for most of the raw materials are due for payment.
