PRACTICAL VALUE OF THE EXCURSION 



It calls fresh attention to the conclusions of geology concern- 

 ing the building of the earth and the development of life-forms. 

 It reveals to many a new world of the imagination. Science 

 has swept into oblivion the whole brood of mythological 

 monsters, centaurs, griffons, chimeras and dragons, that once 

 delighted the lovers of the terrible and strange, but now it is sub- 

 stituting the monsters of geological lore. It arouses new interest in 



"The fairy tales of Science and the long result of Time." 



It will stimulate a more healthy interest in science for its own 

 sake. 



4. Let us hope that this expedition may arouse such lasting 

 interest in scientists and the patrons of public museums in the 

 wonders of the West that it may be but the first of a long series 

 of similar vacation excursions which may prove of mutual 

 advantage to all engaging in them and to the public at large.
