—A fringe of islands, about 700 of which are suitable for human habitation by virtue of drinking water and a harbor for boats, lies to the south and west of the mainland of Finland. About 30 of these are each large enough to support more than 50 families. At the other extreme, there are about 300 lodging only one family each. The total population of these islands runs into many thousands, but each is so isolated and the means of sustaining life are so limited that the fate of the islanders is far from enviable. Little wonder, therefore, that the population of these islands has been reduced by about 25% since 1910, owing partly to the counter attractions on the mainland and the low birth rate, about 15 per 1,000 during the last decade. The main source of income of the population is fishing. In
