The solid axle is of a diameter through the journals of 2 ft. 2 in., a diameter across the flanges of 5 ft. 3 in., length over all 41 ft., and weight 28 tons.

The Massilon (Ohio) Bridge Company has received an order for the construction of a cantilever bridge 562 feet long and 18 feet wide, which is to be built by the New York Dredging Company at Honda, on the Magdalena River, in Colombia, South America.

Navigation on the Amoo-Darya is to be extended considerably, so that Russian steamers will proceed upward on that river to Feisabad-Kalch, which is only about 200 miles from the scene of the recent Indian frontier troubles. - Uhland's Wochenschrift.

A new process of manufacturing artificial stone has been patented in England. The stone is formed in steel moulds, which can be adjusted to any size, shape or design for which the finished stone may be required, and solid blocks weighing several hundred pounds have been easily produced.

M. Berlier, the well known engineer, has laid before the governments of Spain and Morocco a project for the construction of a tunnel under the Straits of Gibraltar. The execution of this plan would have immense economic consequences, so that its fate will be followed with interest. M. Berlier is the inventor of a new method of subterranean boring.

"The sale of the steamers 'Pennsylvania,' 'Ohio,' 'Indiana,' 'Illinois,' and 'Conemaugh,' by the International Navigation Company to the States Steamship Company for the Pacific trade leaves but five steamships flying the American flag crossing the Atlantic Ocean," says The Marine Record. "They are the 'St. Paul,' gross tons 11,629.21; 'St. Louis,' gross tons 11,629.21; 'New York,' gross tons 10,802.61; 'Paris,' gross tons 10,794.86; 'Evelyn,' gross tons 1,963.44, the latter three built in English shipyards and denationalized."

John Murphy, general manager of the United Traction Company, of Pittsburg, reports the average life of motor gears on his line as two years, and the average life of pinions, nine months. He is employing the gears and pinions of the Simonds Manufacturing Company. The service is an exceedingly severe one, on account of the many grades on the line. The average life of trolley wheels is 1,000 miles, and the conditions under which they operate are quite severe, as the company has on its main line eighteen railroad crossings. A tempered copper wheel is employed.

According to a recent correspondent of The Buffalo Express, in the Pennsylvania oil region during the last year over 300 gas engines have been placed on oil leases and are doing satisfactory work. The engines vary from 10 to 50 horse power. Every big machine shop in the oil regions is turning out gas engines. The machine shops are also using gas engines to drive their own machinery. During the last year twenty of the Standard Oil Company's pipe line pumping stations have been equipped with gas engines. In all the new stations and in old ones where new machinery is needed, the gas engine will be preferred. Where natural gas cannot be had and coal was formerly burned, gasoline is used. The pumping station engines are all provided with electric ignition.

In a recent issue of The Railway Age is published the following, based upon the last report of the Interstate Commerce Commission: "Last year the railways of the United States carried over 13,000,000,000 passengers one mile. They also carried 95,000,000,000 tons of freight one mile. The total amount paid in dividends on stock was $87,603,371 - call it $88,000,000. Of the total earnings of the railways, about 70 per cent. came from freight service and 30 per cent. from passenger service. Let us assume, then, that of the $88,000,000 paid in dividends, 70 per cent., or $61,600,000, was profit on freight service and $26,400,000 was profit on passenger service. Let us drop fractions and call it $62,000,000 from freight and $26,000,000 from passengers. By dividing the passenger profit into the number of passengers carried (13,000,000,000), we find that the railways had to carry a passenger 500 miles in order to earn $1 of profit - or five miles to earn 1 cent. Their average profit, therefore, was less than two-tenths of 1 cent for carrying a passenger (and his baggage) one mile. By dividing the freight profit into the freight mileage (95,000,000,000) we find that the railways had to carry one ton of freight 1,530 miles in order to earn $1, or over fifteen miles to earn 1 cent.

The average profit, therefore, was less than one-fifteenth of a cent for carrying a ton of freight (besides loading and unloading it) one mile."

The railroads in the United States have cost about $60,000 per mile, and probably a considerable percentage of this has not entered into the construction of the railroads and the equipment of same, says "Signal Engineer" in The Railroad Gazette. The railroads of Great Britain have cost about $240,000 a mile, and yet we claim for the United States more luxurious travel than can be found in Great Britain; and this is true so long as the travel is safe. The difference in the cost of construction in the United States and England may be found in the item of safety appliances. The railroads of Great Britain carried during the last year 800,000,000 passengers, with safety to all but five, and this was possible because the railroads, instead of expending their capital in luxurious equipment and passenger stations, chose rather to equip their lines with the most improved signaling and interlocking. The railroad companies of the United States in expending large sums for handsome and convenient terminals and luxurious cars are placing monuments before the public eye which naturally lead to the belief that every appointment of such roads is on the same high plane, and it requires much less expenditure to furnish luxurious equipment to be carried over 1,000 miles of road than it does to equip 10 miles of the 1,000 so as to make it safe; and since the expenditure for safety appliances and permanent way is not seen and felt by the passenger so long as he is carried in safety, it is not, therefore, so prominent before the public gaze as is the handsome station and the palatial car.
