- 26 the splendid locks at the Soo is about 40 minutes, of which but a part is due to the filling or emptying of the lock chamber and is chiefly oc- cupied in moving the ship in and out small and making fast, opening and closing gates, etc. Twenty-five lockages even at 40 minutes each is 16.6 hours. Such a canal as this would necessarily be, bodies available as a part of the channel, can- without any large of water not be navigated by a loaded ship at over 3 miles per hour, or 75 hours without any interruptions of any sort; a total of 91.6 hours. As a matter of fact, no man who knows anything of canaling with a loaded ship would ex- pect to do even so well. The number of lockages is, however, beyond ques- tion very much underestimated. Since the terminal levels are practically iden- tical, an elevation of 200 ft. certainly means 400 ft. of lock lift, and an aver- age lift of 16 ft. would be most im- probable, if not impossible. The canal advocate will, of course, claim that the figures as to speeds and time are unfair: no. canal advocate was ever known to use anything less than five miles per hour in his estimate, and just as certainly no loaded ship The ob- jections which exist to a sea level canal was ever known to make it. at Panamaandsetforthin THe Marine Review for April, 1909, apply also in this case. And in addition, a condition has to be considered which will not exist at Panama, and that is the nav- igating. of the ship in. light trim,..a common and inseparable incident of lake business. To take a ship "flying light" through such a ditch in anything more than a light breeze is a physical impossibility. And above all, 'Iet it be lake is not asking for it and would not use clearly understood that shipping it if it were built, and the only people who are pushing it are those who have land to sell or are in some way inter- ested in its construction.

THE MarINeE REVIEW © ORE SHIPMENTS. Ore shipments during December were 519,525 tons, making the total movement for the season of 1909 41,- 683,873 tons, an increase of 395,118 tons over the record of 1907 when 41,288,755 tons were moved.

The figures compiled by THe Ma- RINE Review from the returns sent in by the various dock companies show that iron ore receipts at the Lake Erie ports during the season of 1909 were 33,672,825 tons, out of a total movement of ore by lake of 41,683,873 tons. Lake Erie docks on Dec. 1 held a balance of 8,965,789 tons, which is the largest store on hand in the history of the traffic, the previous high figure being in 1908, when 8,441,533 tons were on hand. During 1908, the total shipment by lake was 25,427,094 tons, of which Lake- Erie docks received 20,414,491 fous and held a balance on Dec. 1, 1908, of 8,441,533 tons. During 1907 the total shipment by lake was 41,- . Lake January, 1910 = held a balance on Dec. 1, 1907, Fy 7,385,728 tons. During 1906 the total shipment by lake was 37,513,595 tons, of which Lake Erie docks re- ceived 32,076,757 tons and held a bal- ance on Dec. 1, 1906, of 6,252,455 tons. The reserve of 8,965,789 on Lake Erie docks Dec. 1 is amp for winter consumption. Never in the history of the trade have 5,000,000 tons gone forward from dock to furnace during the winter season. Shipments to furnaces between May 1d, and. Dec. 1, 1909, aggregate 30,077,304 tons, compared with 17,- 453,258 tons in 1908, 29,787,018 tons. in 1907, 27,615,392 tons in 1906, 24,- 311,720 tons in 1905, 16,658,806 tons in 1904, 16,903,013 tons in 1903, 18,- 423,364 tons in 1902 and with 14,- 204,596 tons in 1901. The shipments to furnaces during the season of navigation as referred to are determined in this way: First we have the amount of ore on Lake Erie docks before the opening of navigation, May 1 last, 5,370,268 tons; add to this the receipts of the season just closed, 33,672,825 tons, and the total is 39,043,093 tons; de- duct the amount on dock Dec. 1, 8,-° 965,789 tons, and we have 30,077,304 tons as the amount that was for- warded either direct or from dock to furnace yards. It is, of course, understood that the difference be- tween the total output of 41,683,873 tons which was shipped from the Superior mines during 1909, and the receipts of 33,672,825 tons at Lake Erie ports, is ore that went to places other than Lake Erie ports, such as the furnaces at Lake Michi- gan ports. The accompanying table shows receipts at Lake Erie ports 288,755 tons, of which Lake Erie and amounts on dock during six docks received 35,195,758 tons and years past.
