Mountains granite prevails, having mica slate and gneiss dip- 
ping to the east in Maine; similar rocks occur on the west side, 
together with ‘‘Cambrian,” all inclined towards: Lake Cham- 
plain. The Green Mountains are made out to be an immense 
mass of quartz rock. There seems to be an important element 
of truth in this representation, while the details cannot be relied 
upon. In the neighborhood of the White Mountains the older 
rocks make their appearance, but granite does not constitute the 
central axis of the White Mountains; the strata are not uniformly 
regular in their dips outward from the axis, and the Green 
Mountains are not made of quartzite. 
It is difficult to find accurate reports of the cost of Jack- 
son’s survey, but it would appear probable that the explorations 
and studies cost less than $10,000, and the expense of publica- 
tion was met by other appropriations. Owing to the wish to 
reduce the size of the last item of expenditure, the map has no 
coloration, so that it is difficult to pronounce upon its value. 
The Second Geological Survey.—in 1868 the legislature passed 
an act providing anew for the geological and mineralogical sur- 
vey of the state, for which the sum of $3500 was annually 
appropriated. It was stipulated that brief annual reports show- 
ing the progress of the survey should be made, and ‘when the 
survey shall be completed, a report of the same, accompanied 
by such maps and drawings as may be necessary to elucidate 
and exemplify the same, shall be published under the direction 
of said state geologist.” 
On the eighth of September 1868 the writer was appointed 
state geologist by Governor Walter Harriman. The work was 
prosecuted for ten fiscal years, the. time used for exploration 
being somewhat less than would appear from the records. So 
far as the survey had a connection with the state government, 
its enabling act carried two favorable provisions: (1) It was not 
necessary to go before the legislature every year with a request 
for a new appropriation. If this had been the case, probably the 
life of the survey would not have extended beyond three years. 
(2) Only brief reports of progress were expected annually.
