Here and there, no doubt, will stand quite solitary homesteads, homesteads that will nevertheless be lit and warmed by cables from the central force station, that will share the common water supply, will have their perfected telephonic connection with the rest of the world, with doctor, shop, and so forth, and may even have a pneumatic tube for books and small parcels to the nearest post-office. But the solitary homestead, as a permanent residence, will be something of a luxury—the resort of rather wealthy garden lovers; and most people with a bias for retirement will probably get as much residential solitude as they care for in the hire of a holiday chalet in a forest, by remote lagoons or high up the mountain side.
