The advantage which the landlord derives from such improvements seems at no time to have been greater than what was sufficient to compensate the original expense of making them. In the ancient husbandry, after the vineyard, a well-watered kitchen garden seems to have been the part of the farm which was supposed to yield the most valuable produce. But Democritus, who wrote upon husbandry about two thousand years ago, and who was regarded by the ancients as one of the fathers of the art, thought they did not act wisely who enclosed a kitchen garden. The profit, he said, would not compensate the expense of a stone wall; and bricks (he meant, I suppose, bricks baked in the sun) mouldered with the rain, and the winter storm, and required continual repairs. Columella, who reports this judgment of Democritus, does not controvert it, but proposes a very frugal method of enclosing with a hedge of brambles and briars, which, he says, he had found by experience to be both a lasting and an impenetrable fence; but which, it seems, was not commonly known in the time of Democritus. Palladius adopts the opinion of Columella, which had before been recommended by Varro. In the judgment of those ancient improvers, the produce of a kitchen garden had, it seems, been little more than sufficient to pay the extraordinary culture and the expense of watering; for in countries so near the sun, it was thought proper, in those times as in the present, to have the command of a stream of water, which could be conducted to every bed in the garden. Through the greater part of Europe, a kitchen garden is not at present supposed to deserve a better enclosure than that recommended by Columella. In Great Britain, and some other northern countries, the finer fruits cannot be brought to perfection but by the assistance of a wall. Their price, therefore, in such countries, must be sufficient to pay the expense of building and maintaining what they cannot be had without. The fruit-wall frequently surrounds the kitchen garden, which thus enjoys the benefit of an enclosure which its own produce could seldom pay for.
That the vineyard, when properly planted and brought to perfection, was the most valuable part of the farm, seems to have been an undoubted
