The article presents titles and abstracts of various research articles, related to geography. "A Canoe Journey in Southeastern Labrador," by Henry G. Bryant is about Labrador, which with its large unexplored areas and comparative accessibility, presents an attractive field for the pioneer explorer. The Atlantic seaboard is desolate owing to climatic conditions produced by the Labrador current. In addition to that, the article presents information on various other abstracts related to geography.

The article presents information on the papers that were submitted by researchers Earney and Mason on iron ore pellets published by the "Annals," in September 1969. Both papers contain some questionable statements and data. The paper by Mason contains a number of factual errors, and the statistical data used for analysis are inaccurate and, in some cases, practically meaningless. Some of the points that were noticed in the papers are presented in the article. The modest increase from fourteen to seventeen million tons between 1955 and 1960 was dramatically outstripped by pellet production in 1965 as output more than doubled from seventeen to thirty-eight million tons. These figures apparently are not from any publication of the U. S. Bureau of Mines, contrary to the implication given by Mason.

Geographical researcher John C. Hudson's recent paper on "A Location Theory for Rural Settlement," is an important addition to the sparse literature on this aspect of geography, especially as he emphasizes the need to give further consideration to the process of settling in order to understand settlement form. One can expect that Hudson's theoretical contributions and methodology will be employed in other empirical investigations. There is a need in the measurement and interpretation of rural settlement patterns both on a theoretical and on a more local descriptive level, to differentiate between the patterns created by farm holdings and those resulting from farmhouse distributions.

Most cities are influenced by those cultures which they serve and represent. At the same time, the cultures are influenced by their respective cities. This mutual relationship among cities and cultures constitutes a complex of processes of functional interrelationships. The geographic approach to these processes leads to the delimitation of twelve major world-regions and several sub-regions that are characterized by the areally varying processes associating cities and cultures. A system of world-regions of this nature is proposed in the present paper. The proposed system places every city of the world into a hierarchy of functional regions, far beyond the city's own hinterland. Every city is then visualized as a molder and reflector of its cultural environment. In addition, the following implications of such a regional system on the field of urban geography are discussed. First, the urban geographer is able to contribute to regional studies by considering the influence the cities have upon a given region. Secondly, the urban geographer adds another aspect to the research on any city by purposely studying the city as the expression of the surrounding cultural realm. Thirdly, the proposed regions are a tool for systematic and comparative study on the regional variation of cities from one culture-region to another.

This paper reviews ideas of American geographers on geographic land form analysis and proposes a framework within which geographic land form studies can be identified and related to other land form studies. The following approaches are identified as geographic 1) descriptive analysis of the present land form, 2) functional analysis of land form, 3) analytical studies of the covariation of individual land form elements; and 4) analytical studies of spatial variations in land form. Selected methods used in such studies are summarized and evaluated. Special emphasis is placed or descriptive methods. [ABSTRACT FROM AUTHOR]

This paper, by showing various applications of infrared imagery, is intended to stimulate thinking among geographers toward the potentiality of airborne infrared imaging systems as geographic research tools. By making use of the capabilities of airborne infrared systems the researcher will gain valuable supplemental information which in many cases is unattainable from conventional aerial photography. The geographer interested in earth science investigations will find infrared imaging systems quite valuable in the determination of certain geological formations and structural features. Hydrographic features, owing to the variation in land-water heat capacities, show quite well on most infrared imagery. Certain types of vegetation may be differentiated more readily in the infrared, than in the visible, portion of the electromagnetic spectrum. Other applications to archeological research, rural applications, such as wildlife inventories, and urban investigations, such as commuter studies are also suggested. High resolution infrared radiometers are already being used to great advantage in meteorological studies from orbital altitudes. By applying infrared imaging devices in their research geographers, while gaining valuable supplemental information, may provide data useful in systems development. At present, the geographer may find it difficult to apply infrared sensors to his research because of the relative expense of the system or U.S. Department of Defense security classification of the imagery, but he should be prepared to employ this new tool as more infrared imagery is declassified and more systems come into use.

This paper presents three methods for mapping levels of economic development and applies each to the case of India. First, to provide a substantive addition to knowledge about the economic geography of India; second, to demonstrate that even within nations generally recognized simply as "underdeveloped" one can meaningfully map differential sub-levels of development; and third, to stimulate critical discussion of the various methods by which maps of economic development can be made. The chief statistical problem is how best to combine the several series of individual indices into a single set of areal ratings.

Over wide areas of the earth the railroad has been a decisive instrument in the creation of many of the most important patterns of human geography. Railroads are clearly phenomena of prime geographical interest, yet if it is true that "each means of transport has its own technological characteristics and its spatial layout, or network," it is equally true that their understanding of the inherent geographical implications of these characteristics and networks is far from satisfactory. The following paper attempts to add a further dimension to this common quest by focusing upon the comparative genetic character of two railroad networks.

This treatise is a summary of the temperature aspect of climate only. Concise statements of the ways in which certain aspects of climate differ from place to place are given in some texts and treatises dealing with meteorology and climatology. The aim of this paper is to point out and explain those relations which correspond, in so far as the nature of the subject permits, to the laws of other sciences. Some of the "laws" that have been included are, laws concerning the heating and cooling of the earth, distribution of heat in point of time, distribution of heat over the earth, delay of heating and cooling, diurnal range and seasonal range.

The article presents some comments of geographical researchers on the research papers submitted by them. Just because settlers prefer to locate farmhouses close to a road does not mean that in doing this they also choose non-central locations with respect to the rest of the farm. Working land on both sides of a road is quite common. Also, the tendency of farmhouses to cluster along a highway can be discerned via machine map reading techniques. Quadrant sizes smaller than the period of the road network would detect these. And such linear clusters would not, of course, be related to the settlement processes that are discussed in "A Location Theory for Rural Settlement," by J.C. Hudson.
