Exercise 6. Give a written translation of the following passage.

 

The technique of making steel had not fallen into oblivion. In Anglo-Saxon literature many references are made to steel and also to ‘steeling’. Conversion of soft wrought iron into steel by cementation continued to be practised. The technique seems to have been improved by the Danes locally to satisfy the demands of small economic units.

The conquering Normans were greatly impressed by the industrial efficiency they found in England. German skilled workers were accustomed to reside in England because of the high level the Anglo- Saxon had attained in metal - making. For example, knives made in England, were valued much in France during the Middle Ages.
