GEOLOGIC 3IAP 



The compilation of the base for the new geologic maip by C. O. 

 Vermeule C.E. is completed, and a contract for the publication 

 of 2000 copies has been made by the state printer with the firm 

 of Julius Bien & Co. The base is now being photolithogpaphed, 

 and proofs of two sheets have been submitted. The correction of 

 the proof and the compilation and drafting of the geology are 

 rapidly, progressing, and it is expected that the new edition will 

 be ready for distribution by the close of the next calendar year.
