ON THE 



GKOWTH OF CERTAIN CALIFORNIA FOREST 

 TREES AND THE AIETEOROLOGICAL IN- 

 FERENCES SUGGESTED THEREBY. 



BY ROBT. E. C. STEARNS, Ph. D. 



While in Napa county, daring the month of October, 

 1881, I noticed in a clearing lately made on the top of 

 Howell Mountain that, in felhng, most of the large trees 

 had been sawed across at the butt, instead of being chopped 

 down with an axe, thus making an even cross-section or 

 plane surface, and admitting of the counting of the rings 

 of growth. 



It was my intention at the time to have taken these 

 notes myself, and, further, to have made a diagram show- 

 ing the exact width or thickness of each of the annual rings, 

 in order to make ^ comparison of one tree with another
