Summary. — Research on current land-parcelling meant for the selting up of a skiing-resort at Le Praz de Lys (Upper Savoy) has proved highly interesting. It turns out first of all that the unearned increments of the land constitute the main profit for mountain people to derive from such an enterprise. Secondly, if private interests loom large, they do all the more so as the resort is to be created in mid-altitude, where private estates generally abound. Lastly, the alternatives which have been put forward are original because they imply not so much a division of the land which is largely in favour of the Common Land as a mechanism of transferring of the rights so far never resorted to, whose aim is to improve both justice and the protection of our natural environment.

Abstract. — Commercial and artisanal town since the Middle Ages, Crest had become by the 18th century a flourishing textile center wich supported the important surrounding rural areas. Today it is no more than a small industrial center comprising both traditional and modern activities, but to an insufficient extent. Crest is taking on more and more the role of a service town, with a rather limited zone of attraction

Summary. — The upper valley of rio Elqui (Central Chili, province of La Serena, latitude 30° S) was englaciated on Quaternary only in its upstream part, but two local glaciers (La Laguna and Allende) obstructed its talweg during maximum extension (Riss). Wiirmian and late glacial forms are similar to rock-glaciers of dry mountains. The weakness of present running accounts for the good conservation of quaternary moraines. Their spatial contraction between downstream rissian deposits and upstream residual glaciers leave doubts about Riss- Wiinn interglacial age reality. Therefore, although north-american qua- ternarists tendancy would be to divide the only Wiirm in many stages, alpine terminology may be retained to define precisely internal or external position of main vallums. Key-words : aridity, obturation, glacial age and glacial forms, Riss, Wiirm.
