VOL. 40. CLEVELAND, MAY, 1910. NEW YORK No. 5 European Ore Carrying Steamship HE steamship Vollrath Tham, -lately constructed by R. & W. Hawthorn, Leslie & Co., of Hebburn-on-Tyne, to the order of the Rederiaktiebolaget Lu- lea-Ofoten, has had incorporated in its design many novel features and ranks as one of the most interesting types of 6 in., and a deadweight capacity of 8,000 tons. She has been fitted by the North- eastern Marine Engineering Co., with triple-expansion engines, and steam is supplied by three cylindrical boilers, working at a pressure of 180 lb. There are two ballast pumps, capable of hand- ling 600 tons per hour. On her trials, to quick and economical loading and dis- charging, and, in substitution of the ordinary holds, she has been divided into a series of hoppers and discharging holds, as will be gathered by a refer- ence... to, the line engravings, Figs. 2 and, 3i Before the construction of the vessel 0 Fic. 1--Ture Ore CARRYING STEAMER VOLLRATH THAM. vessels now being used for iron ore transport. P The vessel, which is seen in Fig. 1, has been built to the British Corporation highest class, has a length over all of 390 ft., a length between perpendiculars, over stem and stern post, of 376 ft, a breadth of 56 ft. 6 in. a depth of 33 ft. the Vollrath Tham attained a speed of over 10 knots, and on the occasion of her maiden voyage, in ballast, from the Tyne to Narvik, the average speed ex- ceeded 1034 knots, per hour, whilst the speed, loaded, has~ since averaged 914 knots. The vessel has been specially designed to carry iron ore with a view was commenced, a series of prolonged experiments were carried out at the Hebburn shipyard with a quantity of the actual ore in order to ascertain the most efficient mechanical device for operating the doors, the correct angle of slope for the various ridges and the proper size for the chutes having previously been
