not adapted to any other uses than that of fencing and for fuel. The 

 western or coast line of mountains must become the principal source of 

 supply, in lumber for building purposes, except that which may be ob 

 tained by importation. 



The coast range consists of two principal and distinct lines of ridges 

 for a distance of nearly two hundred miles of their length ; these are 

 separated from each other by wide and long valleys that continue almost 

 uninterrupted through their whole course, and should be considered as 

 distinct ranges of one system both from their geographical position as re 

 lates to the mountains in which they are situated. The valleys have 

 recieved different names, as the Santa Clara and Salinas ; and these again 

 are subdivided and recieve local names even on the same line of plain ; 

 they can be considered strictly but one valley, the lineo f continuity be 

 ing broken by the interposition of a range of hills, not exceeding in 

 altitude three hundred feet, and even below these figures. 



This division of the Salinas from the Santa Clara is caused by a low 

 spur putting in from the Gabilan range, in a direction nearly north-west. 

 Across the northern part of this spur the PajaroEiver, an inconsiderable 

 stream, holds its course, discharging its waters into the Bay of Monterey. 

 The extend and geographical position of these two valleys would seem to 

 warrant a different arrangement than that at present existing in reference 

 to the coast range ; as they form a line as distinct and clear in the sepa 

 ration of the two principal ridges, as the valleys Sacramento and San 

 Joaquin in the separation of the coast range on the west from the Sierra 

 Nevada on the east. 



The division of the coast range proposed will be bounded as follows : 

 commencing at a, point due east of Monte Diablo on the valley San Joa 

 quin, the latter and the Tulare valley to form the east line to the inter 

 section of both ranges with the San Bernardino Mountains, near the thirty- 

 fifth degree north latitude, thence running west to a point that shall cut 

 the west base of this range, and lying on the north-western border of the 

 Salinas, thence north along the west border of the latter, and also the 

 west border of the valley Santa Clara to the south-east terminus of the bay 

 San Francisco, following the east coast of that bay to the point San Pablo. 

 This range inclusive to be denominated the Monte Diabolo, and all moun 

 tains to the west of these lines to be still termed the " Coast Mountains." 

 This division in the mountains now bearing the latter name, will become 

 the more necessary when it is understood that much difficulty now exists 

 in localizing phenomena and transactions that have from time to time 

 occurred, as well also as another distinctive feature which marks them, 

 viz : their relative age, the one being of comparative recent date to the 

 other. The term "Coast Eange" implies a line of mountains following 

 the coast only, but which, as it is used at the present time, includes a 

 chain whose eastern base is as far removed from the coast, as the foot 

 hills of the Sierra Nevada are from Bodega Bay on a line cutting through 

 the City of Sacramento to the ocean. This chain, it will be seen, is se 

 parated by broad and long valleys, as distinct in their characteristics^ as 

 the Sacramento and San Joaquin, while their length, including the bay 

 San Francisco, equals the latter and has nearly half its average breadth. 

 The geological and mineral characteristics of the two ranges are equally
