In the summer of 1904 the writer had the pleasure of travehng 

 with Professor F. E. Lloyd, editor of the Plant World, from 

 the southern to the northern portion of Arizona, of ascending the 

 San Francisco Mountain, of visiting the Grand Canyon of the 

 Colorado, and of camping opposite Bright Angel creek b}' the 

 muddy waters of the Colorado. x\lthough only a general recon-

 ground is Franscria dimiosa. Giant cactus Cereus gigaiitciis, in the back-

 and so much that was suggestive was seen that the writer wishes 

 to recommend the San Francisco Mountain and the Grand Canyon 

 region to some botanist as a suitable and profitable locality in

 I wish to state briefl}- how the canyon and the mountains were 

 visited by us in 1904 in the hope that others may repeat the jour- 

 ney and share the pleasure of our experiences.
