Title:
U.S. Coast and Geodetic Survey Condition of Field Work Porto Rico and Virgin Islands June 20, 1926.
Description:
This is a 1926 U.S. Coast and Geodetic Survey map of Puerto Rico and the Virgin Islands. The map depicts the island of Puerto Rico (Porto Rico) and the Virgin Islands. Culebra Island and Vieques Island, districts of Puerto Rico, and Mona Island, an uninhabited nature preserve, are labeled. These islands are part of Puerto Rico. Desecheo Island is also labeled, and is an uninhabited nature preserve administered by the U.S. Fish and Wildlife Service. In the Virgin Islands, St. Thomas, St. John, and St. Croix in the U.S. Virgin Islands are labeled, as well as Tortola in the British Virgin Islands.
Created for the Annual Report of the Director, United States Coast and Geodetic Survey of 1926, the 'condition' of field work accomplished by the agency is illustrated, using different forms of notation. 'Condition' means the total amount of field work accomplished to date. Hydrography surveys are depicted in light blue and have been completed around all the islands in the region. Other hydrographic surveys using the wire drag method and are illustrated in red, which have also been extensively undertaken. In wire drag surveys, a wire is attached to two ships or boats and set to a certain depth by a system of weights and buoys. The wire is then dragged between two points, and if it encounters an obstacle, the wire becomes taut and forms a 'V'. This reveals submerged rocks, wrecks, and other obstructions with more accuracy, along with an accurate reading of depth. Topographic surveys, which cover the entirety of the smaller islands and the coastline of Puerto Rico itself, are illustrated in green. Triangulation surveys are depicted by the red interconnected triangles and, with the exception of sections of the interior of Puerto Rico, have been employed extensively throughout the region.
A key explaining the different notations utilized on the map is located along the bottom border, and a table in the lower left corner lists other forms of survey work completed in the region. The table states that, in Puerto Rico alone, the only type of station which has not been established is a gravity station, whereas in the Virgin Islands, only magnetic stations and primary tide stations have been set up.
This map was produced by the U.S. Coast and Geodetic Survey for inclusion in the Annual Report of the Director of the Coast and Geodetic Survey. The director in 1926 was E. Lester Jones.

Customs:
International buyers are responsible for paying duty and taxes on delivery. DHL or FedEx will contact the buyer by telephone to arrange tax payment if it is levied. Duty varies by country and we cannot predict the amount you will be charged. Some countries are duty free, others are not. Typically, a customs duty and/or VAT tax will be assessed on all parcels to continental Europe. Sometimes duty or tax is due in China, but is seems very random. Hong Kong, Singapore, Korea, and Taiwan have never assessed duty on a map we shipped. Maps shipped to the UK should be duty free as educational materials, but from time to time duty of 5% is assessed incorrectly by the UK customs agents.
Insurance:
All shipments are insured privately against loss and damage. All of our shipments require a signature for insurance purposes.
