Title:
U.S. Coast and Geodetic Survey Progress of Field Work Porto Rico and Virgin Islands Fiscal Year 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, field work accomplished by the agency is illustrated, using different forms of notation. Hydrography work, finished around St. Croix, is depicted in light blue. Other hydrographic surveys were completed are St. Croix and Culebra and in the straits between Puerto Rico and Culebra and Vieques using the wire drag method and are illustrated in red. 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. No topographic surveys were conducted in the region during 1926, per the map, and triangulation surveys were conducted on and around Culebra.
A key explaining the different notations employed on the map is located along the bottom border and a table in the lower left corner lists other forms of survey work completed during 1926. The table states that a seismological station and a magnetic observatory were established on Puerto Rico and that two primary tide stations were established in the Virgin Islands.
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.

All shipments are insured privately against loss and damage. All of our shipments require a signature for insurance purposes.
