Bituminous and Asphalt Rocks of the United States. The 
Twenty-second Annual Report of the U. S. Geological Survey, 1901, 
part 1, pages 211-452. inclusive, contains a report on Bituminous and 
Asphalt rocks of the United States by George H. Eldridge. 
On page 259 of this report he makes a statement that the region 
around Higginsville and Odessa are the only portions of Missouri 
where bituminous rock has thus far been found. Now if he had con- 
sulted the Missouri geological reports or the persons most familiar with 
Missouri geology his published report might have been more complete 
and correct. I have mentioned the occurrence of bituminous rock in 
seven published volumes between 1872 and 1898 recorded in authorized 
state and United States publications and in periodicals and journals of 
scientific societies. I mentioned it in five places in the Missouri geo- 
logical report fur 1872 and fourteen places in the geological report for 
1873-74. in Vol. 8, for 1895. are three pages and in Vol. 12, for [898, 
there are four pages devoted to the discussion of bitumen in .Mr-
