ThePresident made an excellent address, reviewing the yearswork. The paper on Preserving Ties presented at the previous meet-ing was generally discussed. Mr. J. Kindelan read an interesting paper on Rail-joints, de-scribing a large number of joints devised and in use. NOTES AND NEWS. A New Pavement.—Some time ago an experimental sectionof street pavement composed of wooden blocks and cast-ironsupporters was laid down in Sheffield, England. The accom-panying engravings, from Iron, illustrate a further experimentin the same town on similar lines, but instead of cast-iron, asin the former case, wrought steel is used in combination withwood. In place of the cast-iron upright stud of a cruciformsection previously used at the angles of the blocks, there is. now an angle-piece of steel (fig. 1) having a base or foot whichrests directly on the concrete foundation. The advantages ofsteel over cast-iron are obvious, but the difficulty has been toadapt steel in such form as would be producible without mak-ing the cost so great as to preclude its general adoption. Thefirst piece of combined wood and iron paving has now been inuse three years, and shows little or no sign of wear. Thepiece described in our previous notice is still in use under ex-ceptionally heavy traffic. The third piece, which comprisesabout 100 square yards, has been laid down in Queen Street,Sheffield, where there is a great amount of traffic. Half of it isin cast-iron, but of much lighter construction than that in SavileStreet, the other half is in steel, as shown in fig. 2 of our en-gravings. It has been in use seven months. This pavementis made by the Carmaxill Road Paving Company, of Sheffield. Heating Metals by Electricity.— An
