I replied to my bebés that I thought the ien story a ‘‘ hoax," 
but if it would please him would soon find out if it were or not. I ac- 
cordingly addressed a letter to the editor of the paper in which the article 
originally appeared, asking him on what authority the publication was 
made. He answered that it had been written by a sub-editor (giving his 
name) who, however, had left his employ, but to whom he would forward 
my letter. A few days ago I secured a note from the sub-editor afore- 
said, in which he says: 
“To be frank with you, ‘Explorations in Utah’ was a sensa ffset tl 
coming report of Profteiés Powell in the Colorado Canons,’ d ooa Samuel necp à in 
Colorado,' both of which have since appeared. From personal observation in the region me 
us.” 
I should perhaps mention that ** Professor Scott's" explorations were 
alleged to have been undertaken under the belief that the race of the 
mound builders of the Mississippi Valley had migrated to Mexico and 
Central Mexico, and that traces of their transit might be found on the 
way. — E. G. SQUIER.
