Instead of digging up tlie old service pipes for their entire length, with considerable damage to streets and yards, the new method involves only a small opening in the paving where the service pipe connects with the main. Through Work has been started on the further development of the Pykara hydro-electric scheme in Madras in connection with a dam across the river near Mukurti, with the object of increasing the storage capacity. So far the work has consisted principally of surveying and boring, and the results are said to be promising.

The work done on the former date was attended with very unfortunate delays to trains, which conditions were still being felt on Thursday, the 6th. From the explanations given to the Press by the railway company it would appear that there was no delay in carrying out the vast alteration, but that the disorganisation mainly was due to a too fine adjustment of some of the electrical gear and to the method employed for working those connections which have one sot of points in one line and another set in a second line, and where both work pine timber, equal to that of good quality imported red or yellow deal of joinery grade,-can be produced in this country, but the rate of growth must not be exoessive-- that is, the timber should coiitain on, ha average twelve rings or over per inch radius. As no very slow home-growxi timber was tested, it is not possible to state whether the choicest grades of the imported qualitie^oan be produced in the British Isles. On the other hand/1where strength is of primary consideration, an average of nine rings per inch radius is permissible, though the optimum strength is not reached until the growth ha* slowed down to approxi mately twelve rings to the inch.
