GEOLOGICAL AND NATURAL HISTORY SURVEYS. 301 



Three suites of specimens are mentioned by Jackson in his iirst 

 annual report as having been collected and put up in cabinet form, 

 and the suggestion is made that one set should be sent to the Ports- 

 mouth Athenaeum and one to Dartmouth College, the remaining por* 

 tion being sufficient for the use of the legislature. Among these 

 materials was a specimen of the first bar of tin smelted in America, 

 the same having been prepared from tin ores found at Jackson, New 

 Hampshire. This bar was subsequently destroyed by fire, but a 

 second portion is still preserved among the collections of the United 

 States National Museum at Washington. 



In the first annual report the method of procedure is outlined 

 somewhat as follows: Knowing the strata to pursue a general north- 

 east course, Jackson proposed to cross them several times at right 

 angles and also to follow along their lines of strike. " These lines of 

 exploration will divide tlie territory into triangular areas, the 

 boundaries of which will be known, and various excursions across 

 them v.-ili make the knowledge of each strike more or less accurate." 



Cross sections were described from Portsmouth to Claremont 

 through Concord, from Concord to AYakefield, from Wakefield to 

 Haverhill — all measured by IMessrs. Whitne}^ and Williams. Doctor 

 Jackson personally measured another from Concord to Winchester. 

 Messrs. Whitney and Williams also traveled to the northern corner 

 of the State as far as INIount CarmeL The field work closed after a 

 tour to the AVhite IMountains. 



The second year's explorations began at Nashua, a party of assist- 

 ants exploring the southern range of towns between Nashua and the 

 Connecticut River. Doctor Jackson himself explored between 

 Nashua and Portsmouth in the opposite direction. Thence he 

 traveled to Madison, Mount Chocorua, Jackson, Randolph, Lancaster, 

 Shelbourne, back to Lancaster and Dixville Notch. Next he meas- 

 uied a section through Vermont from Lancaster to Lake Champlain. 

 Meanwhile Messrs. Channing and E. E. Hale examined the northern 

 frontier. The remainder of the year's work consisted of explora- 

 tions in Littleton, Franconia, Landaff, Orford, Lyme, Canaan, Graf- 

 ton, Amherst, and Kcene. 



The third report states that towns not previously surveyed wei'e 

 examined as far as possible. 



No library was formed. 



Expenses. — The total cost of the survey was $9,051.15, the amount 

 being appropriated at the rate of $2,000 annually for the first three 

 years and $3,051.15 for the fourth. This was exclusive of the cost 

 of publication, the figures for which can not be ascertained. A bill 

 for $2,417.35, paid in full of all claims on December 19, 1844, was 

 thought by Prof. C. H. Hitchcock to relate to the illustrations of
