G. K. Gilbert’s elaboration of Laccolite phenomena in Utah, see 
his Report on the Geological Survey of the Henry Mountains, The 
Powell Surrey for 1877, and also for the naming of two of the 
laccolite peaks of this range "Mount Holmes," and "The lesser 
Holmes." 
In event of particular interest while in the field was 
the encounter with a band of Hava jo^ Indians• After they had cap¬ 
tured our entire herd of stock, the recapture of the animals was 
made at midnight by our chief packer, Thomas Cooper. A full 
account of this interesting episode is included in the appended 
copy of my field note books. At about the same date the party in 
charge of Professor Gardner, in the area adjoining mine on the 
north, was attacked and kept under fire in their exposed camp until 
they were compelled to leave their outfit, take to their riding 
animals and escape. I was greatly surprised to have them appear 
suddenly over a ridge at the left of my line of march two days 
later. They were glad to ^oin me as their provisions were exhausted. 
Returning to Washington October 12, 1875, I took up the 
year’s work of study, report writing, and custodianship of collections.
