192 The American Geologist. September, 1904. 
The Little bridge, of which a cut is herewith shown, taken 
by permission from the Century MagarAne, is a mile and half 
below the Caroline bridge. Its dimensions are not so large as 
those of the Caroline and Augusta bridges. It has a span of 
two hundred and eleven feet, four inches. The under side of 
the arch is one hundred and forty-two feet above the bottom 
of the canyon. The crown of the arch is eighteen feet, eight 
inches thick and the roadway is thirty three feet, five inches 
in width. "The slenderness of this aerial pathway and the 
fact that the canyon here opens out into a sloping valley be- 
yond rendered it possible for the camera to give a proper im- 
pression of loftiness. Indeed, judging from the photographs 
alone one might suppose this to be the highest of the three 
bridges, whereas in fact it has but little more than one-third 
the altitude of the wonderful Augusta arch. It was compara- 
tively easy to reach the top of this bridge, and among Long's 
notes I find the following: 'Rode our horses over. I am the 
first white man who has ever ridden over this bridge.' '' 
The foregoing descriptive notes are condensed from the 
interesting account by Mr. Dyar, who used the notes made by 
Mr. Horace J. Long who in company with a cattle man named 
Scorup visited the region March 13, 1903. Mr. Scorup had 
seen the bridges in the fall of 1895, but they were discovered 
earlier in the same year by Emery Knowles. 
The region is one of the Cliff Dwellers, and abounds in their 
remains. It is evidently destined to become one of great inter- 
est. The Century Magazine is to be thanked for the beautiful 
but simple presentation of these natural wonders to the atten- 
tion of the public. n,,h. w.

This communication is of much interest to palseontologists in mak- 
ing them acquainted with a new fauna of Cambrian time in soutliern 
Europe.
