Mr. F. BINNS, M.P., proposing a vote of thanks to the Author, said he always found that the most useful and popular papers were the ones which dealt with the things that really mattered in the day to day work of the engineers concerned. The present paper was one of these, and having done similar jobs he knew the absolute necessity for laying down a basis on which to proceed because the state of muddle into which one got if one had not laid down such a system made it quite impossible to do a job of speedy building. The paper set out planning as it should be.
