WAS WROUGHT IROX A WEAK FACTOR IX THE INDUSTRY? persisted in spite of the formation in 1919, of the British Iron Manufacturers' Research Association. The industry did not, in fact, decline after 1900 faster than those on the Continent and in America. The mistake was to preserve the industry to a greater extent than economically necessary after the advent of cheap mild steel. This was no doubt influenced by the large production and export of British forge pig iron for which there was, of course, a falling demand. There will always be a demand, to a limited extent, for wrought iron on account of its special properties, but it will remain a small item in the total output of the iron and steel industry. The wrought iron industry has, however, left a special inheritance which it is worth while noting in relation to the next chapter of this study—steel production, for the mistake was made of basing the steel industry on the location and lay-out of the iron industry.
