We had made the side trip to the White Canyon, principally 
in order to see these remarkable bridges, compared with which the 
one in Virginia is almost nothing, but we found that the flora was 
very interesting and decided to stay for a few days’ collecting. 
Armstrong Canyon turned out to be one of the best collecting 
grounds we had on our trip. At least one plant, a species of 
Anticlea, is new to science 
Fic. 41. Two small cliff-dwellers’ houses. 
On our return trip we stopped over a day collecting in Mr. 
Scorup's pasture, the only part of the Elk Mountains that had 
not been grazed over so thoroughly by cattle, and hence had 
kept more than other parts its original flora. We owe Mr. 
Scorup thanks for all the favors shown us. Thanks are also 
due Nielson Brothers. On oe to Monticello, we too 
another route in part. We took the usual trail down the south 
slope of Hammond one down the lower part of the same 
found ntisally large cottonwoods (Populus acuminata). One of 
these measured 14 feet in circumference. Near the head of 
Dry Wash we found one of our best collecting grounds.
