For great changes had meantime taken place at the Kenia. New-comers continued to arrive in greater and greater numbers. At the close of the fourth year the population of Freeland had risen to 780,000 souls. A great part of Eden Vale had become a city of villas, which covered forty square miles and contained 58,000 dwelling-houses, whose 270,000 occupants devoted themselves to gardening, industrial, or intellectual pursuits. The population of the Dana plateau had risen to 140,000, who, besides cultivating what land was still available there for agriculture, gave by far the greater part of their attention to various kinds of industries. The main part of the agriculture had been transferred to a plain some 650 feet lower down, beyond the zone of forest. This lower plateau extended, with occasional breaks, round the whole of the mountain, and offered in its 3,000 square miles of fertile soil abundant agricultural ground for the immediate future. Here some 240,000 acres were at first brought under the plough after they had--like all the cultivated ground in Freeland--been protected against the visits of wild animals by a strong timber fence. The smaller game, which could not be kept away from the seed by fencing, had respect for the dogs, of which many were bred and trained to keep watch at the fences as well as to guard the cattle. This protection was amply sufficient to keep away all the creatures that would have meddled with the seed, except the monkeys, some of which had occasionally to be shot when, in their nocturnal raids, they refused to be frightened away by the furious barking of the four-footed guardians.
