Abstract :
MR. TWIGGER : In one thing I fully bear you out, and that is the number of developments which have come along during the past few years. It is a commonplace that in all the things of life, these last twenty-five years have probably produced more changes than in any other twenty-five years in the history of this country. That is most certainly true in the case of foundry work, and I speak more in regard to cast iron. It is bewildering when one thinks of all the special types of cast iron which have been introduced in recent years, together with the vast range which has opened up by the heat treatment of cast iron. One sometimes wonders where it is going to end.
