15. Geological Surveys of the United States. — At the recent meet- 

 ing of the American Association for the Advancement of Science, res- 

 olutions were offered, strong!}' urging the completion of geological sur- 

 veys of the several states of the Union which still remain unfinished.

 minerals, building material, fertile soil, and various productions valu- 

 able in the arts, remain unexplored, and where explorations have been 

 made, there have been delays in the publication of Reports, whi
