    At a two brushwood fences are erected a metres apart in early spring. They are sanded over in a iew weeks (b), and a second tier of fences is placed above them (c). By the end of the summer (d) these also are sanded over. The final planting of Psamma is carried out in the autumn of the first year (e), and this is extended, in both directions, the following spring (f). By the end of the second year the dune slopes should have assumed their permanent profiles (g). The arrow points from the shore. The width planted in G from the foot of the windward slope to the foot of the lee talus is 38 metres. (From F. Solger in Dunenbuch.)
