Note 45 — Chapter VII

As the walls afford valuable space for the growth of the choicer kinds of hardy fruits, the direction in which they are built is of considerable importance. "In the warmer parts of the country, the wall on the north side of the garden should be so placed as to face the sun at about an hour before noon, or a little to east of south; in less favoured localities it should be made to face direct south, and in the still more unfavourable districts it should face the sun an hour after noon, or a little west of south. The east and west walls should run parallel to each other, and at right angles to that on the north side."
