  • Biological survey of the Panama Canal Zone (1912)

    Walcott, Charles D. (Government Printing OfficeWashington DC, 1913)
    At first it was intended to confine the collections to the Canal Zone proper, but as the faunal and floral areas extended to the north and south of this region, it was decided to carry the work into the Republic of Panama, a step which met with the hearty approval of that Republic. The work accomplished has been very valuable to science, including collections and observations of vertebrate animals, land and fresh water mollusks, and plants, including flowering plants, grasses and ferns. Special attention will be given during the coming season to vertebrate animals, insects, crustaceans, rotifers and other minute freshwater animals, and also to the microscopic plants known as diatoms. Includes appendix of papers that resulted.
  • A geological survey of Panama (1913)

    Walcott, Charles D. (Government Printing OfficeWashington D.C., 1914)
    The general plan of the surrey comprises a systematic study of the physiography, stratigraphy and structural geology, geologic history, geologic correlation, mineral resources(including coal, oil, and other fields), petrography and paleontology of the Canal Zone, and of as much of the adjacent areas of the Isthmian region as is feasible.
  • Biological Survey of the Panama Canal Zone (1911)

    Walcott, Charles D (Government Printing OfficeWashington D.C., 1912)
    With the cooperation of several of the executive departments, and of the Field Museum of Natural History, a party of about 10 naturalists was accordingly sent to the zone, and the results so far accomplished have been very satisfactory. Large collections of biological material have been received, including specimens of a considerable number of genera and species new to science. It also seemed important to determine exactly the geographical distribution of the various organisms inhabiting the Isthmus, which is one of the routes by which the animals and plants of South America have entered North America and vice versa. The estimated cost of the survey whichwould have to be met by the Institution is $11,000...
  • Biological survey of the Panama Canal Zone

    Walcott, Charles D. (Government Printing OfficeWashington D.C., 1911)
    exhaustive biological survey of the Panama Canal Zone-will be undertaken in the winter of 1910-11. A part of the fresh-water streams of the Isthmus of Panama empty into the Atlantic Ocean and others into the Pacific Ocean. It is known that a certain number of animals and plants in the streams on the Atlantic side are different from those of the Pacific side, but as no exact biological survey has ever been undertaken the extent and magnitude of these differences have yet to be learned. When the canal is completed the organisms of the various watersheds will be offered a ready means of mingling together, the natural distinctions now existing will be obliterated....
  • The Panama Canal Zone: an epochal event in sanitation

    Adams, Charles Francis (Massachusetts Historical SocietyBoston, 1911)
    An account of events of the Panama Canal Zone in 1911 by the author, C.F. Adams. (38 page document)
  • The Fossil higher plants from the Canal Zone

    Berry, Edward W. (Govt. Printing OfficeWashington, DC, 1918)
    Fossil flora described in the present report is too limited for purposes of exact correlation, which may be expected to be settled by the marine faunas present at most horizons in the Isthmian region. Accompanying table of distribution will show that from the oldest (Hohio) to the youngest (Gatun) plant-bearing formations there is no observable difference in floral facies. This so-called Oligocence series of formations does not represent any great interval of time. (39 page document)
  • Descriptions of new genera, species and subspecies of birds from Panama, Colombia, and Ecuador

    Nelson, Edward W. (Smithsonian InstitutionWashington, D.C., 1912)
    The first of January, 1912, E. A. Goldman, of the Biological Survey, Department of Agriculture, was again detailed on the Smithsonian Biological Survey of the Canal Zone. He returned to Panama in January and remained there until the last of June passing most of this period in collecting birds and mammals on the slopes of Mount Pirri on the Pacific side of eastern Panama, near the Colombian border...(Document contains 27 pages)
  • Two new subspecies of birds from Panama

    Nelson, Edward W. (Smithsonian InstitutionWashington, D.C., 1911)
    While working on the Smithsonian Biological Survey of the Canal Zone, Mr. E. A. Goldman of the Biological Survey, United States Department of Agriculture, collected specimens of two undescribed subspecies of birds which are characterized below. (Document contains 3 pages)
