Show I, j THE AUTOMOBILE i A MINE HELPER t Since- transportation is ono of tho im-' im-' , , nortant factors In mining-, tho introduc-1 introduc-1 , tlon of tho automobile for this purpose Is I ' suggested. "For traveling over hlRh altl- ! tudes In quick limo and safety. It has I ' been shown recently by experiment in Colorado that tho automobile, driven ,1 1 throuph mountainous regions, covered a I distance of 175 miles at a little less thun 'if. 20 miles an hour. 1 1 Xow an attempt la being made to provo ' tho superiority of the automobile for tr.i- versing the great desert of Death valley.
