2 SOUTHERN CALIFORNIA ACADEMY OF SCIENCES 
TRANSACTIONS FOR DECEMBER, 1904. 
I, ACADEMY SESSION, 
At the regular monthly meeting of the Academy, held Monday eve- 
ning, December 5, at the State Normal School, President Dozier presided. 
The Secretary, Mr. B. R. Baumgardt, delivered a lecture on ‘‘The 
Grand Canon of the Colorado,’’ illustrated by the lantern, with slides 
from photographs taken largely by himself and Mrs, Baumgardt, and 
colored by the latter. 
Disclaiming any attempt to fully discuss the geologic and dynamic 
causes of the canon topography, the lecturer introduced a graphic ex- 
planation of the marvelous erosive and transportative power of moving 
water. The picture illustrations, with his lucid and eloquent descrip- 
tions, brought clearly to view the extent and character of the work 
‘done by the Colorado in rock-sculpture and denudation under the peculiar 
conditions prevailing in its track. This collection of slides is par- 
ticularly interesting from its comprehensive character and its delineation 
of both the details of structure and their massing in broad prospective. 
More than usual in similar exhibitions, the very difficult feat of pre- 
senting the idea of distance and real proportion was accomplished. Vivia 
portrayal of the facts by word-pictures left a memorable impress of 
reality, due to the intimate contact of the speaker with his subject in 
the field. EDITOR.
