ae MARINE Vou. Vi. Building the New Navy. Through courtesy of the Railroad and Engineering Journal, New York, two interesting sketches are shown in connection with this article. The first is the Columbia, cruiser No. 12, and for some time known as the "Pirate," on account of her commerce destroying powers. She is 412 feet on load line, 58 feet beam, nominal draft 23 feet, displacement 7,550 tons, hav- ing machinery of 23,000 horse power, which is expected to drive her 22 knots anhour. She has three screws driven by three triplg engines, having cylinders 42, 59 and g2 inches by 42 in- ches stroke. With the central screw working alone 14 knots is ww ee Sin 7 REVIEW. CLEVELAND, OHIO, THURSDAY, SEPTEMBER 15, 1892. No, tt. Lake Freight Matters. On Monday iast there were 11,996,227 bushels of corn and wheat in Chicago elevators and 1,424,000 bushels of wheat at Duluth. Duluth wheat is delayed about fifteen days, as had been expected,and has not yet begun to arrive freely, but under a heavy pressure of receipts, Chicago has begun to take capacity at the rate of nearly a million bushels per day and at an advance of a quarter of a cent a bushel over the rates that have prevailed for three weeks past. This movement has strengthened the lake freight market generally, but there is as yet no substantial assurance of high fall rates. Iran ore shippers are paying $1.05 freely from the head of Lake Superior and shipments have relaxed but little. They are opposing an advance in other rates, on the claim that they are well up on the season's shipments and that " wild " ore charters will not be a factor in the freight market for the balance of the season. 'The iron market has shown some improvement of late, however, and the heavy movement of ore for three weeks past is evidence that dealers are more desirous now of increasing shipments than they were a month ago. Duluth grain shippers have for several days past been offer- ing 3 cents on tonnage to arrive, but the conditions surround- ing this part of the fall trade are not what they were at this expected, with two side screws 17 knots, and with all three 20 to 22 knots is counted upon. Six of the ten boilers are double ended, 21% by 15% feet. A sister ship is also under construc- tion at the Cramps' yard. The other illustration shows the:Ammen ram, building at the Bath Iron Works and nearly ready for launching. She. is 243 feet over all, 43 feet beam and 15 feet deep; displacement 2, - ¥ 050 tons and horse power of engines 4,800. Seventeen knots is _her estimated speed. The vessel is designed upon the longitu- dinal and bracket system, with an inner bottom extending from _the collision bulkhead to the stern. The longitudinals and gir- ders supporting the deck are continuous, converging to the stem casting and to the stern; the frames and beams are intercostal.. The depth of the longitudinals and the vertical keel throughout their length is 24 inches; the girders supporting the armored deck are 15 inches. The vertical keei, two longitudinals, and the armored shelf on each side of the vertical keel are water- tight, forming transversely six compartments, which are divided longitudinally by water-tight frames. By this means the space -between the inner and outer skin is subdivided into seventy-two compartments. The transverse and longitudinal bulkheads be- tween the inner skin and deck armor divide this space into thirty compartments, making a total of 102 compartments in the vessel. time a year ago. Then one big grain firm, controlling about 150 country elevators, started the ball rolling by contracting for a very large amount of tonnage at 4 cents. This business was done mainly by one firm of dealers who were in a position to do such a thing, on account of the country elevators in which they were interested. As is well known, they profited hand- somely by their undertaking, but there is no contracting of this kind now. 'The lake movement of grain from the head of Lake Superior will not be more than two-thirds that of last year at an outside, as the crop is proportionately smaller. The main draw- back to grain shipments, however, is the unsatisfactory con- dition of the export trade, and it is this that causes most un- certainty as to freights. Ina circular letter sent out last week a firm of Buffalo brokers expressed anxiety regarding the ability of Buffalo elevators to again handle the grain this fall, Fears of a repetition of the serious trouble last fall were enter- tained, on account of delay brought on by the recent strike, but little attention has been given as yet to this feature in the business.
