During the years 1835 to 1841, the first geological survey of Virginia, and what is now West Virginia, was conducted under the leadership of William Barton Rogers. His geological work was produced in seven annual reports presented to the Board of Public Works, which were reprinted in 1884 as a single volume by his widow. However, the first geological map from Rogers' survey of Virginia was only published in 1876 by Jedediah Hotchkiss. Rogers gave his geological map to Hotchkiss in 1873 for use in Hotchkiss' book published 3 years later. During the following 10 years, this geological map was produced 13 more times, mostly by Hotchkiss, and each version is slightly different. Some changes are obvious, such as scale, base map, or cross sections, whereas other modifications are subtle, including stratigraphic units, title, or colors. Three versions are hand colored; the others are lithographs. The known versions, by date, are two in 1874, one circa 1875, five in 1880 and one circa 1880, one in 1881, one in 1882, and three in 1884. Interestingly, none of these 14 versions modified Rogers' original geology, although Rogers modified his original stratigraphic nomenclature. A fifteenth version, apparently done without Rogers' knowledge for the Union army in 1862, is the hand colored geological map by Thomas S. Ridgway.

Appalachian Geology

Since Guettard presented his geological map of North America in 1752, over 100 geological maps were produced that cover all or parts of West Virginia up to 1897, when the State Geological Survey was formed. Their quality, accuracy, scale, and general content vary widely, but each contributed to our growing understanding of West Virginia and Appalachian geology. This annotated, chronologic list of maps illustrates this wide diversity and steady improvement of early geological mapping.

The road-cuts and other new excavation works provide an excellent opportunity for upgrading the geological maps in Poland. Such opportunity should not be missed. Updating The Detailed Geological Map of Poland at the scale of 1:50 000 should be the priority. Ephemeral nature of the freshly cut outcrops makes this research rather urgent. It would require an adequate planning and organization. Geological mapping based on the new road-cuts and rock sections exposed by new investments should be one of the main tasks of the Geological Survey of Poland.

The career of Jean-Baptiste-Julien d'Omalius d'Halloy (1783-1875), commencing with brilliant scientific activities and proceeding to his attainment of the highest administrative and political positions, in itself demonstrates that he was an exceptional individual. His scientific career started with a long voyage through the French Empire and adjacent regions, during which he gained an understanding of the geological structure of most of Europe. The geological map he compiled based on his travel notes formed the basis of all future geological maps in the areas that he covered. After the independence of Belgium in 1830, André Dumont was made responsible for the mapping of the whole country, resulting in the publication of a 9-sheet map of Belgium in 1853 on a scale of 1:160.000. In 1878, Belgium decided to produce a more detailed map on the scale of 1:20.000, entrusting the work to Edouard Dupont., but as this appointment was controversial and the mapping at this scale was abandoned and than, the newly created Geological Survey of Belgium published a new 226-sheet map on a scale of 1:40.000. Starting from 1993, after the federalisation of the country, new geological maps of the regional states are mapped and produced.

The Geological Survey of Portugal (GSP) was created in 1857 as part of the Directorate of Geodesic, Chorographic, Hydrographical Works of the Kingdom established at the Ministry of Public Works, Trade and Industry, within a general policy of control over territory. Until its creation, Portugal lacked any sort of tradition in geological research.Despite changes in name and various restructurings, the GSP was able to produce consistent geological research that was up to international standards, releasing two editions of a geological map of Portugal in the scale 1:500,000, the first in 1876 and the second in 1899. In 1918, the Survey was once again reorganised, becoming part of the new General Directorate of Mines and Geological Survey. Portugal was then enduring a troubled period: the young Republican regime established in 1910 faced financial and political difficulties, and there was much social unrest as a result of World War I. These events deeply affected Survey activities. It is clear that between 1918 and 1948 geology and mapping were not among the Portuguese State's priorities, thus leading to a decline of geological research and mapping.

AbstractIn France a National Geological Survey was planned in 1822 by the Corps Royal des Mines, a government institution, in association with its subsidiary, the Ecole des Mines. The first objective was a rapid Survey of the whole of France, with the intention of preparing a general Geological Map of the country, to be followed by a more detailed Survey, based on the Départements. Field work for the general map commenced in 1825, and was completed in 1835 and a Geological Map of the whole of France, on a scale of approximately 8 miles to the inch was published by the Ministry of Public Works in 1841. The project was carried out entirely under the direction of the Ministry, at public expense. As a National Survey it thus preceded that of Great Britain, established in 1835, by some ten years.

Before proceeding to the special subject of this address, I have thought that it might be of interest to the Society to lay before them a brief outline of the history of geological map-making in Scotland, previous to the time when the task was undertaken by the Geological Survey. I do not, indeed, presume to enter upon any general retrospect of the literature of Scottish geology, but will content myself with selecting for remark a few of the more eminent contributors, on whose labours the present general geological maps of the country are based. These maps are compiled from the results obtained by many different geologists, working independently during the last fifty or sixty years. Some of the men whose researches have in this way been made ase of, never themselves produced any map, but their descriptions of the districts traversed by them served afterwards as a basis for the maps of others.
