Collector's notes: This map is just a portion of Butler's Map of the State of California. Streeter calls that the earliest recorded state map of California. There are at least two states of that. The first gives Butler's address as Clay Street; the second gives Post Office Building. The first was in the Streeter auc., no. 2659. Streeter copy. Call earlier state A; later state B. On state A a branch of the upper San Joaquin has the name Chouchillas. On state B this has been removed and a new river off of the San Joaquin just below the town of Mariposa has been added and named Chouchilla. Just below that has been added the river named Frezenau. A creek running off that has the name C. Gold G.. On state B running north from the San Joaquin just west of Washington City is a line called Fine G. Gulch. On state A, between the Mariposa and Merced rivers is a river named Little Mariposa R.; this has been removed on state B. On state A, running off to the south from the south branch of the Tuolumne is a Moccasin Run, a Rattlesnake C. and beween Rattlesnake C. and the south branch of the Tuolumne is Gold V. On state B, the course of Moccasin Run has been changed, and the name changed to Mocca.Flat. Rattlesnake now runs off to the north from Mocca. Flat and beyond that and parrallel is a Cobbs C; Gold V. has been removed. On state A, Camp Seco is located a little north and east of the town of Sonora. On state B, this has been removed and now Camp Seco is found between Mocca Flat and the south branch of the Toulumne. Stanford copy is a pocket map.
