MR. LEARY is a successful emigrant who went out to Australia some years ago and is at present on several months' holiday in this country. Listeners will thus be given evidence at first hand on a question that, quite regardless of whether they have a personal and intimate interest in the subject, is of deepest import to all Englishmen. This talk is the first of a short series which will be continued at 7.25 p.m. on September 3 and 10. In addition, during the autumn months there will be a monthly talk on ' Migration,' under the auspices of the Overseas Settlement Department.
