THE TWINS : TUOLUMXE GROVE, CALIFORNIA 



It is a i _markable fact that the most accurate record of the world's weather, during the 

 past 4.000 3'ears, which we have is written by the trees. The patient comparisons by means 

 of delicate measuring instruments, which have been made by forest experts, reveal the fact 

 that the records written in the past quarter of a century by the United States Weather Bureau 

 and by the big trees of California tell exactly the same story. We are therefore permitted 

 by an examination of the rings of the centuries that have gone before to read of the years 

 of abundance and famine in the land. The "oldest inhabitant" may declare that the winters 

 were once colder and the summers once hotter than now; that there was more rainfall in 

 the older days than now ; but the big tree's memorv is never at fault.
