The pioneer in geophysics has, in most cases, used empirical methods on his first jobs in the field. Frequently, such an initial campaign has been successful in that valuable evidence has been obtained as to the position of a new ore‐deposit. Thereupon the method has received recognition so that additional parties have gone into field work; also, analytic methods have then been applied to show why the particular method succeeded in some cases and now far it would be likely to succeed in border‐line problems. After a discussion of the difference between empirical and analytic procedure, the author reviews the history of one geophysical project—the search for iron ore in the Lake Superior region by magnetic methods—describing the empirical efforts and the subsequent analysis. He then suggests that failures on certain other jobs might be less if the analysis be made earlier, and that there will be an economy, if this analysis be made before field work begins.

The Malagueta Coast can serve as a classic example of a region which was integrated into the world economy as a result of world demand for its resources—spices and labor in the fifteenth/sixteenth centuries, and again in the nineteenth century palm oil, cocos fiber, and labor—and has sunk into oblivion once the demand ceased. It is similar with Liberia's rubber and iron ore industry of the twentieth century. I had wanted to write this paper, which reconstructs the discovery and commercial exploitation of the coast through a systematic analysis of published maps and reports, ever since I walked and paddled along this coast in 1968. Furthermore I intend to review the discovery of the coast in the perspective of overall Portuguese policy and politics (interior and foreign). Last, but not least, this is to help students of Liberian and West African history with a review of the early sources—among which maps are by far the most abundant.The Portuguese legacy to Africa is enshrined in coastal toponymy until today. Avelino Teixeira da Mota in his “Topónimos de origem portuguesa” focused on Portuguese names still surviving in the nineteenth century, but I will focus here on contemporary fifteenth- and sixteenth-century nomenclature and what it might reveal about the African discoveries. The Portuguese initially were attracted by gold at the Rio d'Ouro (later Spanish Sahara), then slaves, and eventually malagueta—a substitute for Indian pepper—commodities known on the Lisbon market and which served to name the coasts: malagueta, marfim, ouro, esclavos. Diogo Gomes was the first to actually see Malagueta on the Gambia in 1445, but the malagueta coast was not discovered until after Henry's the Navigator's death in 1460.

The article presents the history of iron ore mining and production in present-day Poland and takes into account mining and production techniques and the influence of mining on the development of the surrounding areas. Examples of development are presented for the most important iron ore mining centers established since the period of the so-called Roman influences—Lower Silesia in the region of Tarchalice and the Świętokrzyskie region in the area of Góry Świętokrzyskie (Świętokrzyskie Mountains). The oldest traces of underground iron ore mining in Poland date back to the 7th–5th century B.C., and iron production dates back from the 1st century B.C. in the Częstochowa region where economically significant iron ore exploitation started in the 14th century and lasted until the 20th century. Studies showed that the development of iron ore mining in today’s Poland was associated with significant events in the country’s history, for example, with the expansion of a network of fortified castles in Silesia or with the industrial revolution. In each case, the increase in iron production resulted in the development and growth of the surrounding areas.
