In a quiet, level headed approach to his problem, Mr. Stamp indicates, without ever quite saying how to solve it, that the world land question is not truthfully marked either by the fear of over-population or by the need to develop so-called ""under developed"" areas. Rather, it is surrounded by the need to determine the true nature of ""under developed"" and the proper population needed for maximum production with maximum efficiency. To illustrate, one of his examples is the vast increase in numbers hat could be fed if the U. S., Canada and Argentina were to raise produce per farm are to the level of that in Northern Europe. Extreme care must be taken in the development of the yet untouched lands of Africa and the tropics so as to let them mature in the deepest possible accord with their natural tendencies, and, population wise, forced cultivation is not necessary for a well fed world. Mr. Stamp has had a wealth of training- an establisher of the Land Utilization Survey in Britain in 1930 and as an extensive traveller, worker and teacher in Asia, South and North America. Land for Tomorrow is the result of a series of Patten Foundation lectures at the University of Indiana, in 1950. Although one can always point to the absence of regard for the human element when theorizing about how best to move people around, this is an interesting and very readable study-a good companion piece to Josue de Castro's The Geography of Hunger (see P. 723-Dec. 15 bulletin).
