Abstract. The importance of the technical revolution which has been on its way for some five years, the transformation of a number of farms into large concerns compelled to draw fair profit out of the land induces one who studies the space occupied by cultivated lands to give special attention to new tendencies and grant prime importance to such documents as those describing the lots of cultivated lands (« parcellaires »). The description of these documents sets problems as to the collecting of datas, the way to present the results and their cartography. In the texts below, we attempt to give indexes of parcelment so as to make the comparison easier between various complex situations among which it is advisable to lay down precise examples in a chart. The rate of evolution of these « parcellaires » is not everywhere the same. Lots of cultivated lands tend to be grouped so as to give the farmer larger surfaces and fewer lots to cultivate. Such an evolution is not always wished by farmers, nor is it always advisable. In some areas where special cultures are grown, the evolution seems to run counter. Together with the above mentioned major tendency, the functional grouping of cultivated lots leaves room to a speculative splitting of the farming concerns at a later date. It is more and more observed that the farming concerns which do not lack drive cultivate lands in the neighbouring « communes » (districts or parishes, no exact equivalent : districts administrated by a mayor assisted by a local council) ; and we are thus confronted with varied and complex situations according to the farming system and the type of management of these farming concerns.

Abstract. The outburst of farms in the departement of Mayenne : from cattle-dealers to other farmers Cattle dealers have formed extensive (puzzle) farms whose land is found on several communes distant from each other. Some other farms without any unity in space have developed together with concentration, by tenancy, purchase, retaking ; but farmers are adopting slowly those new structures, which are not wide-spread, so that the dealer's extensive farm keeps its originality.

Abstract. Much attention is currently given to the changes that have taken place in the south during the last decades both because of the profundity of these changes and because of the fact that the wide gulf which has traditionally separated the South from the rest of the nation has diminished. The diversification of the various regions of the South makes it necessary to analyse each region separately, in order bo better understand how each has been affected. In this article we will attempt to observe three completely different southern areas ; and 3 different types of changes. 1. The Ozarks, a mountainous, rural region consisting of a poor white population, has experienced during the last decade a slight increase in population owing to the impact of rural industrialization and to its settlement by the retired elderly. 2. The coastal plain of Georgia is part of the Deep South ; it was, until the beginning of World War II a veritable hunger pocket. To day emigration is almost at a halt, the average income has risen and regional differences have been stabilized. The causes for this dramatic change are being analyzed, with special consideration given to the role of the military bases in the area. 3. More than one million retired people live in Florida to day, most of them settling there upon their retirement. In order to understand the reasons which cause so many aged americans to settle in Florida, we have tried to examine a complex set of geographical, social, economical and cultural factors. 1.
