Table 6 shows a stand farther south on the west slope of the 

 Sierras in Madera Count}-, Cal. The same species, except Douglas 

 fir, are represented here as in Table 5. The diameters run very high, 

 especially of yellow and sugar pine. 



Lower down in the foothills of the Sierras there is an open stand 

 of yellow pine which resembles that in Arizona and Colorado.
