WORLD POPULATION LIMIT. WASHINGTON, June 19. Professor Albrecht Penck. of Holland, yesterday addressed the International Congress on Soil Science. The speaker said the limit of population of the world, with all the land capable of cultivation tilled, was about 80,000,000,000. There were still vast areas to be drawn into the service of man. Also in the greater part of the world the productivity per unit could be very much increased. Many people denied that the white man could exist in the moist tropics for more than one generation or so. He believed the white man could acclimatise himself if he migrated step by step, and very slowly, from the high border regions into the inoist plains.
