The lakes have more steam vessels of 1,000 to 2,500 tons than the com- bined ownership of this class of vessels in all other sections of the country. _ The number of steam vessels of 1,000 to 2,500 tons on the lakes on June - 30, 1892, was 321 and their aggregate gross tonnage 534,490.27; in all other parts of the country the number of this class of vessels was,on the saine date, 217 and their gross tonnage 321,784.6.

It is of thrilling interest and although written by one of the seamen serving life sentence for the mutiny, the account given bears the stamp of truth. Not only in this case but in many others, seamen are no doubt mistreated 'by unprincipled masters and mates. There are undoubtedly some extenuating circumstances on the other side, but a man as intelligent as the writer of the account has proven himself to be has probably been punished sufficiently for the crime, even if he was entirely to blame, by the seventeen years of imprisonment to -- which he has been subjected with a fellow seaman nnder similar sentence. The object of printing the story at this time is to show the claim for clemency which is set forth in a petition for the pardon of the men, which is now being signed for presentation to President Cleveland. © THE story from Alaska about the United States man of war Mohican being fired upon in Behring sea and disabled by the Ha- waiian merchant steamer Alexandria created coniderable interest in marine circles around the lakes. Commander Nicoll Ludlow, who is in charge of the Mohican, the flag ship of the Behring sea fleet of eight vessels, was until a year ago stationed at Chi- cago as inspector of the ninth light-house district. He is an effi- cient officer and has had his share of sea duty, but will at least be compelled to stand the fire of a number of joking letters from friends on the lakes as the result of this story, whether it proves true or not. It is avery popular belief that when the water enters the stoke hold of a sinking vessel the boilers burst. Attention has been directed to this error through discussion in English jour- nals regarding the sinking of the Victoria. Asa matter of fact tie there is not an instance on record of the boilers of a sunken steamer being found on examination to be burst. 'The cold water merely condenses the steam in the boiler, and thereby creates a vacuum, and instead of there being a bursting pressure, there is actually a collapsing pressure. What gives rise to the bursting theory is that the cold water entering the furnaces is partially converted into steam, and this follows the path of least pressure, with the result that a body of smoke, steam, and ashes is forced through the tubes up through the funnel. TERE is nothing surprising in the fact, that though ship- ments trom all other ore shipping ports are very much behind those of previous years, the movement from Marquette on June 1 was about 50,000 tons ahead of last year. Marquette's gain is explained by the low lake freight rate of 50 cents, which was the same as the rate from Escanaba,notwithstanding that the rail rate from the mines to Marquette is 20 cents lower than the rate from the mines to Escanaba. Ninety cents isa phenominally low figure for rail and lake charges on ore delivered at Ohio ports from the Marquette district. 'Therewas some ore carried by way of Marquette at that figureand avery large amount of it atg5 cents, and shippers who could in any way secure ready cash to pay the freight were, of course, alive to the advantages offered them. AN English exchange prints a list of ten vessels launched by Harland & Wolff of Belfast, Ireland, during six months end- ing June 30, last. They are all of steel, five are twin screws, and their aggregate gross tonnage is 38,146, or an average of 3,814 tons. Still, a New York contemporary discredits our statement that this is the greatest ship building establishment in the world. We are willing to take on a. fair share of home pride, but in view of such a record as this it 'is absurd to pro: claim greatness for the plants of the Newport News company, the Cramps, or any other ship building concern in America. Ir took Gen. Poe of the war department just a few days to 'overcome the objections of a Canadian collector of customs at Amherstburg to dredging a portion of the 20-foot channel in Canadian waters near Bar point. He dredged the big Lime- Kilns cut without any interference, but the light-house board raised an international question over putting two lights of a value of about $300 on the edges of this same channel. The Mineral Industry. The MARINE REVIEW has received from the Engineering and Mining Journal, New York, a volume of 628 pages entitled "The Mineral Industry, its Statistics, Technology and 'Trade for . 1892." As it is designated Vol. I, it is evidently the intention of the publishers to put forth companion volumes each year. There are chapters on aluminum, antimony, asbestos, asphal- tum and other mineralsof that class, while large portions of the book are devoted to iron, steel and copper, and the mineral production of each country is reviewed seperately. In the stat- istics Mr. Rothwell, editor of the Engineering and Mining Jour- nal, has brought together the results. of the eleventh census, the work of the geological survey, the bureau of statistics of the treasury department, the bureau of the mint, the Iron and Steel Association, etc., with modifications; and for 1892, in addition to the usual and generally accessible trade reports for iron, steel, anthracite, quicksilver, petroleum, and the gold and silver 'sta- tistics of the mint officials, has added the results of an extensive original canvas of the various branches of the industry. Among the names of the gentlemen credited with the preparation of seperate chapters are those of several well-known specialists. The enterprise shown in undertaking a publication of this mag- nitude is highly commendable, and the comparative promptness with which the results have been presented to the public is espec- ially creditable. The Imperial Statistical Bureau of Germany wrote in reference to the book that it was specially valuable on account of its early publication, enabling readers to become com- pletely acquainted, a few weeks after the close of the year, with the mineral productions of the past. The Scientific Publishing Company, 27 Park Place, New York, will mail the book on receipt of $2.00.
