_ description, - 506 RECORD ORE LOADING FOR A SINGLE SPOUT. The Iron Trade Review of Oct. 14 contained a description of the iron ore properties of the Nova Scotia Steel. & Coal Co. at Wabana, Newfoundland. In the description the statement was made that ore was loaded aboard ves- sels at the company's dock through a single spout at the rate of 2,000 tons per hour. This was really so sur- prising a performance that The Iron Trade Review hesitated to publish the statement without further corroboration. The system of loading ore upon ves- sels has reached a high state of per- fection on the great lakes. Over 10,000 tons 'of ore were put aboard the steam- er Corey at Two Harbors in 39 minutes recently, but this was through 33 spouts. | The statement, therefore, that the Nova Scotia Steel. & Coal Co. loaded 2,000 tons per hour through a single spout seemed incredible until an explanation of the performance was received from Thomas Cantley, general manager of the company. His explanation of the machinery and physical condition that permits this is quite interesting. He writes: As shown lby the illustrations and the loading-pier at Wa- bana has only one chute or spout, notwithstanding this, the rate of ship- ment of 2,000 tons per hour has on many instances been exceeded. We think that we are more or less con- versant with what can be done by all the principal ore-loading piers 'both on this continent and abroad, and have long been aware that we were prob- ably putting more material over a single spout than was possible in any Other installation in the world. The secret of our success in this direc- tion is not far to seek. First, we have a shore-pocket in the upper part of a "V"-shaped gulch. This pocket has a capacity of between TAE MarINE REVIEW December, 1909 Fic. 2--OreE Loapinc Pirr: 25,000 and 30,000 tons. A tunnel is driven underneath this pocket, in which is installed a large and very powerful bucket-conveyor, the buckets being fornied out of steel sheets ap- proximate "V"-shaped in section with a capacity of over one ton each, the supporting links being about 42-inch centers. This conveyor, after passing gut of the. tunnel, is carried on a trestle to the top of the pier, and drops its load directly into a small bin holding from 500 to 700 tons. The spout is attached to the outer face of this bin in such a manner as to give it considerable flexibility, that is, its outer end is capable of moving about 30 degrees on either side of the right- angle line of the dock. On its outer end is attached what we call a trim- mer, which device enables us to shoot the ore to either wing of the ship's hold. The conveyor itself will easily convey from the shore-pocket to the small pier pocket at considerably over 3,000 tons of ore per hour, and has done so daily for months. We have .

By this we mean that the lapsed time from the moment of beginning to load un- til all the cargo was aboard, and in- cludes the time lost in shifting the ship so as to bring the spout to bear on four different hatches. In other words, a steamer of 8,000 tons has been loaded in three hours and twenty minutes. This record has been equal- led in numbers of cases in vessels of other dimensions, The method of loading at Lake Superior docks by a large number ot hatches is, of course, quite different, and in some cases is a very much simpler one. BRITAIN'S GIANT CRUISER RECORD TURBINE POWER. The cruiser, or, to be more correct, the battleship cruiser, which is to be started on at Devonport Dockyard next month, is evidently to be a record maker in size, power and speed. It has been stated that the order for the turbine machinery has been placed with Messrs. Vickers Sons and Maxim of Barrow, who were the constructors of the Dread- nought's turbines, and although there is no official. confirmation of the ru- mor it can be taken to be correct. These turbines are to be no less than 70,000 I. H. P.; a record power for the world. The horsepower of the Mauretania is 66,000, giving a shade above 25 knots. This new cruiser will be some 200 ft. shorter, a few feet narrower, and yet will have 4,000 more horsepower. The present St. Vincent class of Dreadnoughts now completing have about 25,000 I. H. P., while the Invincible class, which have reeled off 27 knots have 45,000 I. H. P.
