The wind has torn up of the plant-carpet and carried it off along with the fine-soil, leaving a bare gravelly plain with isolatcd plant-covered patches. (From photo. by E. Warniing). the finer particles of soil. The vegetation on these piaces is gene- rally sparse, but its meagre development ought not to be put down to any quality of the materials themselves, it is rather due to the unstable condition and the recent formation of the substratum. Similar conditions exist on the rocky floors of the upland plateaux, except that here wind more than water has carried away the finer soil (Fig. 170). The fine-soil appears to be an excellent medium for the growth of piants. Wherever it is allowed to lie at rest, it becomes covered by a closecarpetof piants, and these through their death and decay bring about great changes in difTerent ways according to the con- dition of Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carlsbergfondet (Copenhagen, Denmark).
