Edwards, A Trystan
It is gratifying to have the courtesy of the Institution extended, and a vote of thanks tendered for my paper, even though it received so little approval of the points raised.
THE Editor of The Structural Engineer has suggested that my long career must have brought me in contact with many matters that might prove interesting to its readers
and has asked for an account of my reminiscences. I have not had an eventful life, but it has been a long and busy one, and my memory being still good I have pleasure in recalling the days that have gone by.
Professor Henry Adams
SOME preliminary experiments were carried out comparing the tensile strength at the end of twenty-eight days of a typical Portland cement with that of a spent shale-lime mixture. The spent shale, which was waste material obtained from the Pumpherston Oil Co., was powdered and treated as a puzzolanic material, being mixed with an equal quality of powdered lime, and then gauged in the ordinary way.
