 risburg, 1912. — Under a cooperative agreement between the 

 Federal and State Surveys, topographic and geologic survey work 

 in Pennsylvania has been in progress for several years. There 

 have been issued 137 topographic sheets, covering 51*7 per cent 

 of the state; 31 quadrangles have been surveyed geologically; 

 and five bulletins dealing with oil, gas, paint, ores, and graphite 

 have been issued. Included in the report for 1910-12 are the 

 following papers: The York Valley Limestone by M. L. Jandorf, 

 chiefly economic (pp. 50-129); Geological origin of the Fresh- 

 water fauna of Pennsylvania, by A. E. Ortmann (pp. 130-149); 

 and a peridotite dike in Fayette and Greene Counties, by Lloyd 

 B. Smith (pp. 150-155). The last mentioned paper gives addi- 

 tional details regarding this interesting intrusion, described in
