Today’s map is an antique map of Puget Sound, Washington. Puget Sound is a sound in northern Washington, with several large cities such as Tacoma and Seattle along its coastline. The sound is comprised of a very complex network of waterways going between Washington and Canada. The sound is quite large, with an area of approximately 1,020 square miles (2641.788 square kilometers).
The map is in great condition, apart from some small stains on the upper part of the map. The dimensions are approximately 40.5 inches wide, & 32.5 inches long.
In this article we will discuss the map itself, the translation of certain sections of the map, & analyze this antique nautical map. With that being said let us delve into the interesting & biodiverse area of Puget Sound.
The Chart Itself
As the map is in English, there is no need for translation. The chart is centered around Puget Sound, & lacks colour. It has much detail with almost every curve in the shoreline, each peninsula, & each island outlined perfectly. The names of various areas of Puget Sound are clearly outlined on the map, with most areas marked.
The map has 3 different compasses on it, which would point the reader wherever they wish to go, no matter where they are in Puget Sound. These compasses are located in the upper left corner, the middle of the chart, and the upper right corner.
An Analysis Of The Chart
This chart was designed in 1891 by the United States Coast & Geodetic Survey,
one of the precursors to the National Atmospheric & Oceanic Administration. The United States Coastal & Geodetic Survey was the first scientific Agency made by the United States Government, established in 1807. The Agency was unfortunately abolished in 1970 when it was merged with several other agencies to create the National Oceanic & Atmospheric Administration. The map is fairly accurate as to how Puget Sound appeared at the time. Although it was made for militaristic use, it was likely also used by civilian sailors. It is not clear how this map was made, however, the most popular method at the time was Lithography. The lithographic method was most popular for map making between the early 1820s, & the early 1930s.
In the lithographic method, the artist will draw directly onto a printing surface, such as zinc, or copper, until they are satisfied with the drawing. After this, the surface will be covered with a chemical etch, which will bond it to the surface. With this process, the blank areas will attract moisture to the plate & repel the lithographic ink, while the areas that are drawn on will hold the ink. Water is then wiped onto the unpainted areas to help prevent the ink from deviating. After the map wanted is inked, the paper is laid over it & covered with a tympan, & the tympan is pressed down. Finally, these materials pass through the scraper bar of the litho press. Afterward, an exact copy of whatever was supposed to be printed is revealed.
