Therefore I propose that when morphological survey has not yet started, or is in its preliminary stages, these maps should be taken as starting point. In a following symposium we can discuss in what degree enlarge-ments and changes are necessary for international cooperation. I con-sider here, among others, the cooperation between Galon and Gellert over the glacial accumulation areas; the marked enlargement of the key for the Holocene and coastal regions (the Netherlands, Senegal, Surinam) including areas such as the Sahara.

2. Besides this I should like to fervently plead for a second type of maps of mountain landscapes, in which the substrate is also marked. These are of great importance on the one hand from a functional stand-point, and on the other hand for their significance in morę theoretical problems, such as slope-processes and slope development. In my opinion Jungerius’ map is here the most advanced. Omitting the 34 colors, a sec-tion of the map (fig. 2) together with the topographic basis (fig. 1) and the key is here given as an appendix. If one replaces Jungerius’ map with a morphographical map like those of our Belgian colleagues for example, then, in my opinion, there would be a very important functional map added to morphological survey. My proposal for mountain landscapes is therefore: always make three types of standard maps:

a)    A morphological map, like the Polish map on a scalę of 1 : 50,000

b)    A morphographic-sedimentational detail map (with substrate) on a scalę 1 :25,000, or on a larger scalę if desired.

c)    Finally I should like to plead for an outline map (see map 1 : 200,000 of Czechoslovakia) 1 : 200,000 of all countries.
