One bright morning in early June, on the way from 

 Fyffe to Slippery Ford on the Lake Tahoe stage route, 

 we flushed a Plumed Partridge from the roadside, and 

 my companion remarked that he had flushed a partridge 

 from that place two days before. A search for a nest 

 began among the manzanita bushes and " mountain 

 misery," which latter was thick, nearly ten inches high. 

 After a short hunt we discovered the treasure hidden 

 well at the base of a tall cedar and guarded by the 

 pretty white blossoms and green leaves of Chamsebatia.
