306 BULLETIN 109, UNITED STATES NATIONAL MUSEUM. 



E. C. Eastman, of Concord, had 300 additional copies of the final re- 

 port, with the exception of volume 3, printed at his own expense. 



The annual was printed in connection with the usual legislative 

 documents and distributed with them to all applicants. The final 

 report was distributed by vote of the legislature somewhat as follows : 

 One copy each to every town and academy in the State; six copies each 

 to the New Hampshire Historical Society, New England Genealogical 

 Society, Dartmouth College, and tlie State College; 100 copies to 

 scientific institutions and individuals and others specified, including 

 seven to the Smithsonian Institution. The balance was placed in the 

 hands of the trustees of the State library for sale and exchange. 



The provisions for the sale of these documents were somewhat pe- 

 culiar. A certain number of copies, equal to the number of repre- 

 sentatives and senators, were authorized to be sold at $4 each or $16 

 for the set, to citizens of New Hampshire, who were required to pre- 

 sent certificates of residence in the State, signed by the selectman of 

 the town in which they live. No provision was made for sale in any 

 other way by the State. The cost of publication was $33.85 a set. 



Benefits. — Among the benefits enumerated are : First, a knowledge 

 of the mineral resources of the State, which had aided in the de- 

 velopment of gold, silver, copper, lead, and zinc properties, besides 

 quarries of granite and mica; second, the published accounts relative 

 to the White Mountains were the means of adding several thousand 

 dollars annually to the revenues of individuals; third, the additions to 

 science lay mostly in the classification of the metamorphic and crys- 

 talline rocks of northern New England and the establishment of the 

 distinction between the Atlantic and Appalachian systems of eleva- 

 tion carried out through the eastern United States; fourth, studies in 

 lithology; and fifth, discussions leading to the doctrine of the ter- 

 minal moraine, descriptions of the lenticular hills of drift, later called 

 drumlins, and the discovery of the true origin of the eskers, etc. 



From the study of the rocks themselves a triple succession was 

 thought to have been discovered: First, gneiss; second, feldspathic 

 mica schists; third, hydromica and chlorite schists. Purely local 

 names meaning nothing by themselves, thej' were correlated with the 

 extensions of the terraces into Quebec, Laurentian, and Huroniaa 

 applied to the first and third, v/hile the middle division was consid- 

 ered of enough importance to have the local name employed — Mont- 

 alban. All were called Eozoic* in preference to any of the terms of 

 later suggestion for the entire group. It will thus appear that min- 

 eral characters were used to distinguish the divisions. The foliated 

 igneous rocks were not separated from the related gneisses. Many 

 nuartzites, mica sthists, and slates were referred to the Paleozoic 

 column for stratigraphical reasons. Well-defined Silurian fossils
