ITS WORTH TO THE STUDENT 



Great credit is due Prof. Wilbur C. Knight for his 

 untiring efforts and skill in conducting the expedition, and all 

 members of the party appreciate his work and feel under great 

 obligation to him. 



The thought was indeed most happy which led the Union 

 Pacific Railroad to organize the expedition as it did. 

 Every member of the party returned to his work invigorated 

 in body, enthusiastic in spirit and furnished with an increased 

 fund of illustration for teaching and material for investigation. 

 So that every student who comes in contact with these tourists — 

 and they number thousands will profit by the generosity of 

 the Union Pacific. Further than this some contributions to 

 scientific knowledge will result. Consequently the Union 

 Pacific Railroad is to be congratulated upon having contribu- 

 ted to the progresss of civilization in this regard also, and to 

 it is due the heartfelt thanks of others than those who were 

 the most immediate and evident gainers in this generous and 

 well planned expedition.
