An excursion to the Rocky Mountains under the guidance of the 
Ws Geological Survey followed the adjournment of the congress. 
On reaching Salt Lake the party divided, one part visiting the Grand 
Canyon of the Colorado, the other the Yellowstone Park. A remark- 
able peculiarity of this excursion was the fact that it was made at the 
expense of the visitors, the hosts charging each of them $26s.
