The National Mall is a good place to visit if you want to learn about American history and be a historian. Because of all the different stones used in the construction of the memorials, it is also a good place to visit if you want to learn about rocks and be a geologist.

  “Historians and Geologists actually have many similarities. They both look at past events to better understand the present, and guess what will happen in the future. They both use tools to help them in their research. They both make timelines to keep track of events. The biggest difference is that Historians study the events of humans while Geologists study the events of the earth….”

  ROCK DETERMINATION

  “The Western Editor of Mines and Minerals will, without charge, examine and name, so far as possible, samples of rock sent him, the answers sent by postal card to the send of the specimen.  He will only undertake to name average rocks, such as can be fairly determined at sight; and microscopic or chemical analyses will not be attempted; neither is it always possible to determine with absolute precision and certainty a small sample, or one decomposed and oxidized, and with such samples the sender must be content with the provisional determination that it appears like such and such a rock.
  
  “Questions involving an opinion on mining property, for which an expert would be entitled to a fee, will not be answered, but advice that will aid the prospector will be given.
  
  “The following conditions must be observed by those sending specimens for determination:

  “Each should be distinctly labeled.

  “The name and address of the sender, written very distinctly, must be enclosed in the package.
  
  “The package should be sent prepaid to Prof. Arthur Lakes, Room 32, Barth Block, Denver, Colo.
  
  “A letter should accompany the specimens describing the locality, mode of occurrence of the rock, and other facts, and rough sketches may accompany such description.
  
  “Samples will not be returned unless by request, and where stamps are enclosed to cover postage or expressage and cost of packing.”

(Description: “Where were the women in Geology? This book is a first as it unravels the diverse roles women have played in the history and development of geology as a science predominantly in the UK, Ireland and Australia, and selectively in Germany, Russia and US. The volume covers the period from the late eighteenth century to the present day and shows how the roles that women have played changed with time. These included illustrators, museum collectors and curators, educationalists, researchers and geologists. Originally as wives, sisters or mothers many were assistants to their male relatives. This book looks at all these forgotten women and for the first time historians and scientists together explore the contribution they made to this male-dominated subject. There are individual profiles on remarkable women: Catherine Raisin, Dorothea Bate, Cuviers daughters, Grace Prestwich, Annie Greenly, Nancy Kirk, Margaret Crosfield, Ethel Skeat, Maria Ogivlie Gordon, Marie Stopes, Anne Phillips, Muriel Arber and Etheldred Bennett.”)

      Building Stones Collection: “Rocks utilized for building and ornamentation, composed primarily of material received from the Centennial Exposition at Philadelphia in 1876 and from the Tenth Census at the close of an investigation into the quarrying industries of the U.S. in 1880. Most specimens are from domestic quarries, with some foreign varieties represented, if imported into the U.S. between 1880 and 1920. A substantial portion of the original collection was transferred to the National Bureau of Standards (NBS) in the late 1940s for weathering tests. In 1989, the NBS changed its name to the National Institute of Standards and Technology (NIST). 714 specimens remain.”

  “The ‘Stone in Archaeology – Towards a Digital Resource’ project is based on the large archaeological comparative rock collection housed in the Department of Archaeology, University of Southampton. The main aim of the project has been to create an easily accessible, unique, multidisciplinary, searchable relational database which comprises the principal stones known to be used in antiquity throughout England.

  “This database allows the identification of stone samples by searching on the distinctive physical properties of a stone. The results of the search can be backed up by macroscopic and thin-section photomicrographs of each sample and any geologically relevant information. The resource also provides information regarding the use, quarry location/vicinity and distribution of the stone throughout various periods of history. The resource’s ability to be manipulated in many different ways is one of its strengths.”
