BASCULE BRIDGES IN CHICAGO RIVER. In removing the obstructions to navigation and the flow of water through the Chicago river, the trustees of the Sani- tary District of Chicago, who have this problem in charge, are pushing their work vigorously and as rapidly as the many obstacles to be overcome will permit. The first and probably the most important part of the work consists in the ultimate removal of the center-pier swing bridges. The swing bridge at Taylor street has been entirely removed and replaced by a Scherzer rolling lift bridge, recently com- pleted. The specially obstructive railroad bridge which is near the Taylor street bridge will be removed within a few months, as the new double-track Scherzer rolling lift bridge of 275 feet movable span will soon be completed and placed in service. Contracts have been awarded and work has commenced upon the new Scherzer rolling lift bridges re- placing the swing bridges at Canal and Main streets. Bids are advertised to be submitted May 8th, 1991, for a Scherzer ’ “bridge to replace the swing bridge at Randolph street. The Scherzer Rolling Lift Bridge Co., 1616 Monadnock Block, Chicago, have also recently completed plans fora new bridge at State street to replace the present swing bridge, which was extremely obstructive to navigation on account of a sharp bend in the channel of the river at the site of this bridge. The new bridge will give a clear, unob- structed channel for navigation 140 feet wide; the movable span, center to center of bearings, will be 261 feet 8 inches; the roadways, center to center of trusses will be 4o feet 6 iiches wide, with two sidewalks each 11 feet wide. As State street is the principal retail business street of the city of Chicago, and the bridge is near the business center, it v s decided to make the outlines of the new bridge as artis- ti as possible without increasing the present cost of the s 1cture. The bottom chord is arched and the top chord Pp jects but slightly above the roadway, thus giving a deck b. dge with an unobstructed view. The new bridge, when cc upleted, will not only facilitate navigation, but will pre- ™ ta striking contrast to the present unsightly swing bi ge. The new bridge without extra cost for ornamentation w bein harmony with the growing demand for more artis- ti ridge structures at Ch'cago. The bridge is so designed tL appropriate ornamentation may be added at any time in th future, when funds are available for such purpose. Plans ha e also been completed for new Scherzer rolling lift bridges to replace the swing bridges at Harrison street and Highteenth street, and within a few weeks the Scherzer Co., wijl have completed plans for a new bridge to replace the swing bridge at Polk street. All of the above new bridges will give an unobstructdd channel of 140 feet in width, or wide enough to pass side by side two of the largest lake or ocean vessels likely to enter the harbor of Chicago for many years to come, The wide thannels provided will erable vessels to pass these bridges very rapidly, and time will also be saved as all bridges are designed to be operated by elec- tricity, and may be opened or closed within thirty seconds. As soon as these bridges are completed and placed in ser- vice, the work of removing the other obstructive swing bridges can be proceeded with, without unduly obstructing the street traffic across the bridges. After all the swing _ bridges have been removed and replaced by the more modern type of bascule bridge and the obstructive tunnels have been lowered or removed, the largest lake vessels can readily and “rapidly reach any point along the fifty-six miles of dock frontage comprising the present internal harbor of Chicago, and the delays heretofore caused by the slow passage of the vessels through the narrow opening provided by the old swing bridges will be obviated. The highway traffic will also be greatly facilitated as the present comparatively small and frequent vessels will be replaced by larger vessels, less fre- quent but carrying a larger tonnage. The large, compre- hensive plan under which the harbor improvements at Chi- cago are now being executed so vigorously, indicate that Chicago will not only retain all of its present large marine commerce, but that it will also be prepared for the larger vessels and great increase of marine commerce certain to follow the completion of an adequate ship waterway within the United States, either to the Gulf of Mexico or to the At- lantic ocean. 98 STATISTICAL REPORT OF LAKE COMMERCE.

Rep. (U. S.) 748. ; NOTES. THE Bullock-Wagner sales organization has established a district office at 1624 Marquette Building, Chicago. It will be in charge of Mr. H. B. Foster, who has for about two years served the Wagner Company as sales agent. He will have the able assistance of Mr. E. W. Goldschmidt, formerly of the Western Electric Co., in covering this most important field. THE shipments of iron ore from Cuba during 1900 reached a total of 445,679 long tons, all of which was sent to the United States. The ore was mined at the Daiquiri mines, in the province of Santiago, and the Juragua mines, It seems that the most serious difficulty which the iron ore in- dustry of Cuba has had to contend with during the past two years has been the scarcity of labor. THE Jones protective coating, manufactured by the Jones Metal Coating Co., 1456 Monadnock Block, Chicago, has been specified on the Rialto elevator being built at South Chicago by the MacDonald Engineering Co., Chicago; also on the elevators being built for the Rosenbaum Grain Co. at South Chicago, for Churchill & Co. at Buffalo, N. Y., and for the Cincinnati, Hamilton & Dayton at Toledo, O. The manufacturers state that the United States government is making tests of the paint at the Brookland navy yard. ConsvL-GENERAL GUENTHER, of Frankfort, Germany, says that the captain of a channel mail steamer, which is equipped with an apparatus for wireless telegraphy, reports that on his last trip a message was received from the French light-ship, which is anchored about twenty-five miles from Dunkirk, stating that the latter would be unable to light up the next night unless help arrived from shore. The cap- tain at once sent a second wireless message to La Panne, on the Belgian coast, from which point it was forwarded to Dunkirk by the regular telegraph line. From this place a boat was dispatched to the lightship and the necessary re- pairs were made, THE annual meeting of the stockholders of the Joseph Dixon Crucible Co. was held at the company’s main office, Jersey City, N. J., Monday, April 15, and out ofa possible vote of 7,345 shares, there were 7,285 shares voted for the re-election of the old Board, consisting of Edward F. C. Young, John A. Walker, Daniel T. Hoag, Richard Butler, William Murray, Edward L. Young and Joseph T. Bedle. President, E. F. C. Young; vice president and treasurer, John A. Walker; secretary, George E. Long were re-elected by the directors. Judge Joseph E. Bedle was also re-elected as counsel. THE Age of Steel, St. Louis, notes that steps have been taken by the Standard Oil Co. to invade another field of in- dustry. The engineering branch of the Navy is now the ob- ject of attack, and as an entering wedge the Oil City Boiler Works, of Oil City, Pa., which is understood to be controll- ed by the Standard Company, has constructed a boiler, ex- periments with which are being conducted by a board of naval officers. This board consists of Lieut. Commanders Edwards, W. M. Parks and F.M. Bayley. ‘The boiler is known asthe Hohenstein. It is a straight tube boiler, of standard navy length and dimensions, and capable of pro- ducing 1,000 horse-power. The Oil City works has spent $30,000 in the construction of the boiler and is said to have annouuced that if the experiments cost $200,000 it will be willing to spend that sym, : «
