296.     [MAP]. FRANKLIN & BAKER SILVER MINING COMPANIES. Plan of the Franklin & Baker Silver Mining Cos’. Properties of Colorado; [below lower neat line at right] Lith. by S.B. Linton, 148 S. 4th. St. Philadelphia; [inset at lower left] Longitudinal Section on the Vein of the Baker Silver Lode Scale 300 Ft. To 1 inch; [inset at lower right] Profile Section of Proposed Tunnel of the Franklin Silver Mining Co. Scale 100 Ft. to 1 inch; [compass rose in image at upper left]. N.p., n.d. [Colorado, ca. 1868]. Lithograph map (showing mountains in hachure system, rivers, creeks, gulches, cities, connecting roads, proposed line of a branch of the Pacific R.R., lode locations), with original full hand coloring, neat line to neat line: 38.8 x 71.6 cm; overall sheet size: 45.3 x 77.5 cm. Creased where formerly folded, a few splits at folds (minor losses), a few other minor holes or paper weaknesses, lower blank margin with a few chips, lower left blank corner wanting, but generally a very good copy, fresh overall, with wide margins and bright colors.

     Although labelled a mining plan, this sheet consists primarily of a topographical map illustrating the important mining regions contained within the Clear Creek Valley, which extends from Denver to the headwaters of Clear Creek just below Loveland Pass. Major topographical features and selected mines in the Idaho Springs and Central City areas are shown, plus numerous towns and mining camps, some long lost and forgotten, such as Grass Valley City, Mill City (now Dumont), Golden Gate, Lincoln City, and Mountain City. Absent from the map is the town of Silver Plume (established in 1870).

     The Baker Lode is described by Hollister (The Mines of Colorado, 1867, pp. 257 and 260-262) as having an “uncommonly rich average yield for a lode of such enormous dimensions.” The site of the Baker Mill, later known as Bakersville, is situated near the lode at the lower left edge of the map, just below the present-day Loveland Ski Area. Topography is rendered using a simple hachuring system that gives the region a hilly appearance, belying the true nature of the rugged mountainous terrain. No original copies found in OCLC (only color photoreproductions from the British Library copy are listed). Not in Ellis, Rumsey, or online.

     Lithographer-engraver S. Benton Linton worked at 148 S. 4th Street in Philadelphia. Tooley’s Dictionary of Mapmakers (revised edition, Vol. III, p. 140) notes his Map of the Township of Cheltenham (1867), a political map of Philadelphia and Pennsylvania (1867), and Map of the States of California and Nevada by C.D. Gibbes et al. (San Francisco, 1869). Phillips (America, p. 707) notes Linton’s 1876 map of Philadelphia and vicinity. Anthony Wayne Vodges lists two of Linton’s maps (Geology, Paleontology, and Mineral Resources of California, Sacramento, 1904, pp. 203 & 238). There are other recorded maps by Linton, but he is not listed in Peters’ America on Stone.
