MALLEABLE CASTINGS CO. MILL. NATIONAL TOLEDO SHIPBUILDING CO. _TOLEDO BLAST FURNACE. MARINE BOILER WORKS.-- TAE Marine. REVIEW . 'acquited ~ TOLEDO'S WATER FRONT. The panoramic photograph on the present page shows very. clearly how. the riyer front at. Toledo is building up with important. industries. The National Malleable Casting<'.Co. isijone of To- ledo's oldest and soundest industries, employing from 1,200 to 1,500 men. Adjoin- ing it is the National Mill, for many years the greatest winter wheat mill in the world with a capacity of 4,000 barrels of flour per day. - Then comes the yard of the Toledo Ship Building Co., now undergoing improve- ments which will make it among the most complete yards on the lakes, with capacity for docking the largest steamer o: even the widest passenger boat with- out removing guards. This yard is being literally trans- formed 'since it was acquired from the Craigs and as a. ship yard will be entirely self-contained. The Marine Boiler Works adjoins the plant of the Toledo. Ship Building Co. Then comes the Toledo Furnace Co.'s yard, the 'pioneer company in the manufacture of pig 'iron in Toledo.. This' plant is now undergoing extensive additions. & I. ore and coal docks are now being constructed just below the blast furnace. Be- low the D., T. & J. docks is the Wheeling & Lake Erie railroad's property, with docks at Ironville,~ Gill- more's Shipyard, the Para- gon Oil Refinery, the Lake Erie-Ashville | Block _. plant, the Fishhack Plaster plant, Shepler's paper mill and the Craig Oil Refinery... Then comes the stretch of prop- erty purchased last year by the Cleveland Cliffs Iron Co. for future development. The property extending along the water front from Cherry street bridge to the Malleable Casting --Co.'s plant is controlled by rail- road interests. In:. fact, practically the whole water front: at Toledo has been hy 'corporations who realize its ee indus- trial value. been almost ~The new Dy Ve 29 LAKE CHANNEL. ° The work of constructing a 20-ft. channel in the connecting rivers of the great lakes was begun in 1893 and has continued since. The total amount of money expended in the work to, date has been $3,259,503.60. In the improve- ments in St Mary's river including the west and,.middle Neebish and: Hay lake, the sum of $5,050,655.61 has been expended to 'June, 1906.° The artifi- cially improved: channel in St. Mary's river between Lake Superior and Lake Huron is now 22% miles long, making a navigable route 11 'miles shorter. than the old route through Lake George. The sum of $1,912,523 is needed to com- plete these improvements. The sum of $1,035,577-28 has been expended to date on the St. Clair Flats canal and a new channel is now under construction there. The original depth at the Lime Kiln crossing varies from 12 € to0-76 ft. over a bottom of solid rock. The - sum expended to date in deepening the water over the crossing has amounted | to $2,762,254.47. Concerning the 20-ft. channel, Col: Charles E. L, B. Davis in his annual report says: "Phe: ir proved channels were made available in 1897, but as the water levels' have continually below the mean stage as determined at the begin- ning of the work, the actual Navigable depth has been from one to three feet less than 20 ft." A survey has been made to determine 'the cost of deepening the channel to 22 if. and 25 ft. A, 22-ft. channel can be constructed for $7,738,970. A 25-ft. channel would cost $25,038,367. ' | Mr. E. S. Wheeler, assistant to: Col. Davis, very ingeniously arrives at the total commerce of the Detroit river. He takes the freight movement through Sault Ste. Marie canal, 44,270,680 tons, and compares it with the registered ton- nage of the canal. Then he takes the registered tonnage of vessels passing Detroit, which can very readily be done. through the post office department, and gives to it the same ratio of freight carried as of St, Mary's canal. He therefore determines the commerce of the Detroit river as 55,508,000 tons for the season of 1905. i the improvement of lake chsuuele the géneral government has forged ahead of the municipalities. The depth of water in the inner harbors at the 'various receiving ports does not cor- respond to the depth. in the connecting rivers. The government has under- taken the wo-k of deepening a couple of the outer harbors. at Lake Erie ports to 25 ft, but the inner harbors, + which are under the control of the cities, are comparatively shallow.
