This is a beautiful example of Francis McNally's 1866 map of the World's oceans and ocean currents. It details the various oceans, continental basins, ocean currents and co-tidal lines of the world. An inset map near the lower margin features a rain pattern chart. The map is color coded according to the continental basins. Continents are named but boundaries of countries are not shown. Various rivers, seas, islands and several other topographical details are noted. This map was issued as map no. 2 in McNally's System of Geography.
Rand, McNally and Co. (fl. 1856 - present) is an American publisher of maps, atlases and globes. The company was founded in 1856 when William H. Rand, a native of Quincy, Massachusetts, opened a print shop in Chicago. Rand hired the recent Irish immigrant Andrew McNally to assist in the shop giving him a wage of 9 USD per week. The duo landed several important contracts, including the Tribune's (later renamed the Chicago Tribune) printing operation. In 1872, Rand McNally produced its first map, a railroad guide, using a new cost effective printing technique known as wax process engraving. As Chicago developed as a railway hub, the Rand firm, now incorporated as Rand McNally, began producing a wide array of railroad maps and guides. Over time, the firm expanded into atlases, globes, educational material, and general literature. By embracing the wax engraving process, Rand McNally was able to dominate the map and atlas market, pushing more traditional American lithographic publishers like Colton, Johnson, and Mitchell out of business. Eventually Rand McNally opened an annex office in New York City headed by Caleb S. Hammond, whose name is today synonymous with maps and atlases, and who later started his own map company, C. S. Hammond & Co. Both firms remain in business.
