NOTE ADDED IN THE NATIONAL GALLERY FEBRUARY 7, 1929. 
The many marvels of the par'fe are now - fifty years 
after - fully described and illustrated in a multitute of 
publications. In 1871 the first scientific exploration 
was made by Hayden and a small party though Langford T s 
party had visited the geysers the year before. In 1920 
good roads had been built everywhere and there were 13,000 
automobiles registered in the park. 
In 1925 I was invited to visit the Park by the Super- 
intendent, Mr. Albright, who planned to. furnish me trans- 
portation by rail to the gate of the Park and drive me in 
-r" 
a Park automobile to every point of interest in the Park, 
but I had to decline, my duties as Director of the National 
Gallery were so exacting that the time could not be spared. 
These notes were added by me at my desk in the National 
Gallery, National Museum building, on February 7, 1929, and 
a note may here be made of the fact that recently the great 
painting by Thomas Moran of the Canyon and the Fallsof the 
Yellowstone was purchased from Miss Ruth Moran, daughter of 
the painter, by Mr. George D. Pratt of New York for ten 
thousand dollars, and presented to the Gallery.
