G. Hull. The site of the new combined office, laboratory and home is on the Beleura Hill, overlooking Mornington, bayside holiday resort about thirty miles out of Melbourne. The choice of such a site may come as a surprise to many, but it is the considered opinion of Mr. Hull that there is much to be said for decentralisation, especially as regards a business such as the publishing of "Australasian Radio World," which is largely carried on by mail. In an ideal country setting, with a view extending over Port Phillip Bay from Melbourne to the Heads on one side, and over the rolling hills from the Dandenongs to the Western Port Bay on the other, a brick home has been planned with all the usual features of a country home on the ground floor, but with all the city conveniences as well. Upstairs a large attic is divided into an office, studio, radio laboratory, workshop and photographic darkroom. Mr. Hull hopes to be settled in the new home within a month or six weeks. Working under such ideal conditions he intends to launch an intensive editorial campaign, backed by a technical development programme. At the same time he hopes to be able to catch up with his somewhat overdue task of acknowledging the many hundreds of letters which are at present on hand. - A. G. HULL.
