The average train load increased 129$ to 130j tons, and the net ton-miles per engine from 4181 to 426j. In dealing with the cause and prevention of accidents, in a lecture before the Junior Institution of Engineers, Mr. S. Taylor gave the result of his own experience and the information obtainable from statistics obtained -K are four lines of way for the whole of the distance by inspectors and others under the Factory Acta. In Elland to Normanton on the former Lancashire and 1928 over 154,000 accidents, including 953 fatalities, hire, except for the short length at the west end of were reported from factories, docks, buildings. &c., in Id Station, where the railway crosses the river Calder. this country, and these had been classified according to the length of line is now to be quadrupled under the principal impersonal factors which caused them, and it `pment (Loan Guarantees and Grants) Act. Another would probably surprise an audience of engineers to learn of work which, under the same Act, has been that over 108.000, or over 70 per cent., of such accidents, I by the Government is the widening from two to aud 524, or over 50 per cent., of the fatalities, were Bnes of the 1$ miles between Broadholme signal-box, due to causes not connected in any way with thp use of of Helper, near Derby, and Ambergate.

A good example of how an exhibit at the British Indus tries Fair may bring a firm business from sources quite outside its ordinary sphere of activity was to be found in the scientific and optical instrument section at Olympia. the 93,858 steam-worked trains that ran on the An old-established firm manufacturing lights for navi i Railway in January last, 66*87 per cent, arrived gation purposes and lighthouse equipment, whose principal ' destination on time. 26-63 per cent, were from exhibit was a revolving light for a navigation buoy, minutes late, and 5-26 per cent, were from 6 to 10 had over a hundred inquiries for the use of this particular : late.

The Southern Railway Magazine for giving the statistics from which the above facts 6en extracted, says that fortunately there was very 6 during the month, but heavy gales caused a - amount of dislocation and late running. Following tests made by officers of the Imperial Geophysical Survey Committee, the Tasmanian Mines Department has, says the Iron and Coal Trades Review, carried out development work in the Dundas district, and the results have borne out what the tests indicated. announcement, that the London.

Four ore bodies of copper-nickel have been discovered, and, although this development at the present stage is important more from the scientific point of view, further work may lead to something of a commercial value. There were no indications of these ore bodies on the surface, but the survey indicated that they would be found, anil they were at a shallow depth. The principal instruments used were those of the electro-magnetic type. Smaller ore bodies had been found in the district, but the Department was unaware of the existence of those discovered by the survevs. - I.cIh-i- - K.iir ..I* l":;n . !----- f | The Ganges Canal hydro-electric scheme, which m nearing completion, has cost Rs. 74.4O.O0i>.
