The method of underground storage has, for the time being, been shelved in this country owing to doubt as to its success here. In the Argentine it is quickly superseding all other methods except at railheads and harbours where the rapid handling ability of the vertical silo method keeps the latter in operation but even then extensions to any of these are by way of subterranean additions. By the end of 1958, 30 per cent of all grain storage will be underground and that in spite of this method only having been initiated as recently as 1942. The reason for this development is the certainty, ease and economy with which these structures can be built.
Seven historical floods were routed by the Muskingum method through the Bethulie-Prieska reach of the Orange river. The Muskingum method appeared to yield poor agreement between routed and observed hydrographs at the down-stream station.
At the request of Council, the Johannesburg Branch formed a sub-committee towards the end of 1964 to investigate ways of attracting platteland scholars to the engineering profession.

The annual general meeting and convention of the South African Prestressed Concrete Development Group is becoming famed for including in its day's activities an address by a distinguished overseas engineer. The 1965 convention did not disappoint, for on October 28 members were afforded the opportunity of hearing one of the world's outstanding engineers explain in person aspects of his philosophy and work.
