Fine example of Ransom & Doolittle's rare pocket map of California, published in San Francsico by Warren Holt.
One of the most interesting and detailed maps of the region, called by Wheat "a Nevada map of first importance." (Wheat 1071, illustrated at p. 77). The map was first issued in 1862 (copyrighted 1861). In the first several editions of the map, the Nevada-Utah borders is on th 116th meridian. In one of the 1863 editions, the border is moved to the 115th Meridian.
Rumsey notes that this is a superb map, full of interesting and exotic information. The treatment of the Land and Mining Districts in Nevada and California is remarkable, as are the depiction of the roads in Nevada to the mining districts. The map is also one of the earliest maps of California printed in San Francisco. Includes 4 pages of text.
An exceptional example of this California rarity.
