"old faithful" geyser, Yellowstone national park : Wyoming 



That dependability in Nature is not without its reward is proved by the love of the 

 farmer for his fertile fields and by the age-old worship of the never-failing sun. In the 

 greatest geyser field in the world, one has won greater honor than the rest. They do not call 

 this one ''The Brilliant - ' or "The Giant." but "Old Faithful." For many years it played with 

 great regularity every seventy minutes, but during the summer of 1915 the interval lengthened 

 to eighty-five minutes, owing, it is supposed, to the smaller snowfall and consequent lessened 

 water supply of the preceding winter.
