The books of the United States treasury department contain the names of 3,510 vessels, measuring 1,063,063.90 tons in the lake trade. -In classification of this fleet the lakes have more steamboats of 1,000 to 2,500 tons than the combined ownership of this class of vessels in all other sections of the country.

Bates, United States com- missioner of navigation, 46 per cent. of the new tonnage of the country was built on the lakes during 1889. This is a percentage greater than the work of the Atlantic coast and western rivers combined, and almost equal to the whole work on the Atlantic and Pacific coast. In 1890 the tonnage built on the lakes is but very little less than that built on the Atlantic and Gulf coasts. Tonnage built on the lakes during the past five years was as follows: : No. of boats.

Tonnage passing through Detroit river during 234 days of naviga- _ tion in 1889, amounted to 36,203,606 tons. Ten million tons more than the entries and clearances of all the seaports in the United States, and three million tons more than the combined foreign and coastwise shipping of Liverpool and London. eee Entered at Cleveland Post Office as Second-class Mail Matter. CC eer MARINE writers on the lakes have made some startling claims regarding the speed of fast boats since the Goodrich steamer Virginia went into commission on Lake Michigan. The Goodrich line has, a fast boat, in its twin screw steamer, as well as a craft of more elegance than anything to be found under the American flag, but no one of any knowledge regarding the cost of displacing water will countenance the claim that she can make 23 miles an hour. The Cleveland builders of the boat will certainly not look with favor on such a report, as they did not guarantee for her a speed of even eighteen miles an hour. There is not a boat on the entire chain of lakes that makes twenty miles an hour in runs of any considerable distance. ‘This speed is claimed for the side wheel steamer Frank E. Kirby, recently built by the Detroit Dry Dock Company, and Mr. F. W. Wheeler, the West Bay City builder who guaranteed 18 miles an hour for the City of Chicago, says that he is informed by the owners that she has shown, after her rebuild, 21 miles an hour, but these claims are all of an extreme nature. Such freight boats as those of the Minnesota Iron Company, the E. C. Pope and the Emily P. Weed, now leading the ore and grain carriers, are sometimes credited with more than 14 miles an hour loaded, but these assertions do not come from the men who manage them. It must be remembered that to double the speed takes eight times the fuel. NS “Mr. BLANCHARD is particularly enthusiastic over the scheme for a 20-foot channel throughout the entire lakes,”’ says one of the reports from the congressional party now at the head of Lake Superior. ‘‘He thinks that sucha channel would ulti- mately result in a demand for, and the construction of, a water- way of similar proportions direct to the seaboard.”’ This is an expression of encouragement trom the statesman who is to be the chairman of the next river and harbor committee. Mr. Blanchard will soon find many able supporters in the matter ofa waterway to the seaboard, as the leaders in the lake marine are about to take up the great question of a radical enlargement of the Erie canal. For the present, however, appropriations are needed to make all of the connecting channels of the lakes con- form to the size of the new Sault canal and Hay lake channel, and it is to be hoped that the coming Democratic congress will not delay these legitimate improvements. The story has gone out that the new patty in the House of Representatives proposes a policy of retrenchment, in contrast with the expenditures of the last congress, and that no river and harbor bill will be passed. Mr. Blanchard, and other liberal leaders in his party, can do much to overcome a disposition of this kind toward the national improvements now nearing completion in these waterways. THE war department is acting in a very strange manner re- garding the purchase of the Portage lake canals and it would seem that there is unnecessary delay in the work, notwithstand- ing its importance to the shipping of that district, in the dredg- ing and other benefits that would follow the transfer. The delay came about through the failure of one of the Portage companies to give valid title to lands adjoining the strip through which the canalruns. This title can only be obtained through quit claims deeds from certain parties now in Europe. The adjoining lands would be valuable in the enlargement of the waterways but it is not certain that they constitute a part of the property required to be conveyed under the act for the purchase of the canal. Un- der these conditions the attorney general has decided that the department can accept the canals, leaving the question regarding adjoining property to be settled later, and it was understood on the lakes that with such an opinion from the attorney general, Acting Secretary Grant and General Casey, in charge of the work would go ahead with the transfer. ‘They have not done so, how- ever, and it is now a question whether the transfer will be made this summer or not. Great Pumping Power. The current issue of Engineering of London illustrates a form of triple expansion duplex pumping engines recently made for a South Wales colliery company. ‘They are placed at a depth of about 800 feet, and deliver water at one direct lift to the sur- face. The cylinders are proportioned so as to give a practically uniform effort upon the pump pistons throughout the stroke, the variation being about 15 per cent. Great steadiness of working. is thereby secured. The high-pressure cylinders are fitted with variable cut-off gear, by means of which the cut-off may be varied from half to full stroke. The pumps are of the externally- packed, plunger type, and are capable of delivering 20,000 gallons per hour to a height of 1000 feet, ‘The engines are fitted with. Jet condensers and single-acting air-pumps. ‘The builders, Field- ing & Platt of Gloucester, have made engines of somewhat simi- lar design delivering water from a depth of 1800 feet at one lift. The mean speed of the new Thorn : just ycroft torpedo boat just completed at Poplar, England, for the Brazilian ie tie was 25.858 knots in six runs on the measured mile, while for a continuous run of two hours’ duration the speed was 25.387 knots—the nig est ever attained and continued for the time 3 My guaranteed 24 knots. . pe builder 0. ly oO Be Sy .
