Tourist's Map of Mt. TAMALt/Ais ani> Vicinity. — All lover.s 

 i>{ the forests and mountains of Marin County will welcome this 

 valuable map compiled by A. H. Sanborn, C. E., and P. C Knapp, 

 and issued in 1898. It shows that portion of the country extending 

 from Sausalito to Bear Valley and from the coast inland to Point 

 Reyes Station, Nicasio, and San Rafael. 



It delineates wagon roads, railroads, streji m.<, and elevations of all 

 the principal hills and ridges. The scale is four miles to one inch, 

 and the elevatious are marked in figures instead of by the conven- 

 tional contour lines. This makes the country appear flat instead of 

 mountainous, but it is h decided advantage from a practical stand- 

 point, since all the trails and the various points of interest are 

 clearly nnd accurately shown without the distracting and blurring 

 features of ordinary maps. 



Tlie tourists, mountain trampei's, and anglers will find it useful, 

 as well as the botanist, who is sure to make use of it in making 

 accurate record of the stations of rare and interesting plants. [A.
