Summary. The part on the Danube Delta which is in Roumania is a perfect example of regional planning which combines the exploitation of seasonal and permanent resources, both traditional (navigation and fishing) and recent (the reed industry and tourism). The delta is progressing towards biological stability, but the demographical and social changes are only beginning, because of the fact that young people are flocking to the region, and of the development of migratory movements, and of the creation of a new pattern of population distribution and of the new town of Maliuc. The impulse coming from external pressures will, in the near future, be reinforced by the work being carried out at Sulina and in the Roumanian part of the river valley.

Summary. The action taken by the Italian government, especially that within the framework of financial aid to the south, in order to remedy regional under-development in Mezzogiorno, has alredy extended over more than fifteen years. It began with the agrarian reforms of 1950, and with a widespread attempt to modernise the region and to create indispensible basic economic structures. This was followed up by considerable help given to private investers. Finally, since 1965-1966 a scheme has been set up for the « Planning of Co-ordination of Public Investment in Mezzogiorno », which has its emphasis on industrial development. However, the problems of reforming agricultural structures and of increasing agricultural production, which are still of considerable importance in the south, are far from being solved. In this respect it seems interesting to follow the progress of the first successes achieved by the co-operative movement in the principal sectors of the agriculture of Mezzogiorno, with the help of the « Ente » of development.

Summary. This work is an analytical and quantitative essay on the different ways in which the glacial streams of the Haute-Arve are supplied. For the decade (October 1954 -September 1964) during which the mass-balance of the glaciers was slightly negative - the amount of liquid precipitation staying between 30 % and 40 % ; the snow- melt, at its height in April 70 % decreased until September when it glacial-melt began in May and increased until September when it reached 60 %. The differences in altitude of the various surfaces largely explains the discrepancies between the quantities in the neighbouring glacial streams.

Summary. The 1966 population census in Algeria provides an essential document, coming as it did twelve years after the last proper census, and in that the population had been modified in an exceptional way, both in number and in composition. The crude results seemed to be as useful as they could possibly be (taking into account the difficult conditions in which the operation had to be carried out), in spite of the unequal response to certain questions and no answer at all on certain interesting points, but the analysis of it promises to be long and difficult work. The first data stress the importance of the tendency to group - which locally marks a beginning of a « flight from the land ». The relatively large towns, which are increasing both in number and size pose the problem that it is difficult to define their character as being urban or rural, in a country where the distinction between town and country cannot be made by using criteria which are applicable in Western Europe. which are increasing both in number and size,, pose the problem that it is difficult to define their character as being urban or rural, in a country where the distinction between town and country cannot be made by using criteria which are applicable in Western Europe.
