72 THE STATE GEOLOGICAL SURVEYS AND
In addition to the cooperative scheme described, the mineral industry
of the State has the advantage of a State Analytical Laboratory, the
director of which is the Professor of Metallurgy in the Mackay School
of Mines, and the Analyst, his assistant. The State Analytical Labora-
tory was created more than thirty years ago, and, being located in the
School, is coordinated with the work the State Bureau of Mines is
doing-as economic an arrangement as could be devised.
PRESENT MAIN LINES OF WORK
The same type of work will continue to be done; the importance of
the Hoover Dam area is at present absorbing more time and energy than
any other part of the State, because of the importance of determining
what is in that area. in the way of mineral deposits that will be needed
in the electro-chemical industry which will be created there as soon as
the cheap power becomes available.
PREVIOUS SURVEY ORGANIZATIONS
There was a State Mineralogist from 1866 to 1878. This man was
appointed by the Legislature and carried on investigations throughout
the State, and issued biennial reports.
NEW HAMPSHIRE *
There is no independent State Geological Survey organization in New
lIampshire. The State Highway Department, with offices located in the
State House at Concord, retains on its stag a geologist whose address
during the school year is the Department of Geology, Dartmouth College,
Hanover.
SCOPE OF ACTIVITIES
In the fulfilment of the duties of the Geologist., although emphasis is
given to field and laboratory studies more or less directly related to sup-
port of the highway construction plan, time is given, as occasion arises,
to studies of interest to other state departments, such as Forestry, Public
Service (water-power and dam inspection), Agriculture, and so forth.
The Geologist keeps in touch with these departments, as well as with the
Development Commission, the Governor, and with other officials or in-
stitutions seeking geologic information.

ORGANIZATION
The Geologist is appointed annually by the State Highway Commis-
sionex, with approval of the Governor and Council, and is paid a per
diem salary. The present incumbent, James W. Goldthwait, first ap-
pointed in 1917' has held office continuously cinch t.hnn The tots nmn~lnt

~ , . .. . .
Ot time usually spent is somewhat more than two and a half months a
year, mainly in July and August. Mr. Goldthwait is Professor of Ge-
ology and Chairman of the Department at Dartmouth College. During
the field season one assistant is employed, always an advanced student
in geology at Dartmouth or at the University of New E:ampshire. Oc-
casionally more assistants are needed. In 1930 there were six, including
two men with the master of arts degree, instructors in colleges; the others
were undergraduates, all engaged on detailed survey of gravel and san
deposits throughout the State.
Much of the work is in close cooperation with highway engineers, alla
consists of operating a testing laboratory, studying available materials,
locating best available supplies for particular projects, and so forth.
Some of the work is systematic research, in which geology and engineer-
ing both play a part.
APPROPRIATIONS
There are no fixed allotments or appropriations. Work proceeds under
funds for highway maintenance, charged to administration. The yearly
total recently has ranged between $1,200 and $3,000 (including field
expenses). An estimate of the distribution of expense under heads is as
follows: administration, 10 per cent; geologic work, 70 per cent; mis-
cellaneous, 20 per cent.
PUBLICATIONS
The only official publications are short annual and biennial reports to
the Commissioner. The Geologist, however, prepares occasional articles
for publication in scientific journals, and in the Department's monthly
magazine " New lIampshire Highways." Reports are also prepared for
committees on special missions in which geology plays a role, and so
forth. Publication on a larger scale is scarcely justified either by re-
sources or by present conditions of industry.
PRINCIPAL ACCOMPLISHMENTS SINCE 1911
The Department has cooperated (by funds) with the United States
Geological Survey in a complete topographic mapping of the State, now
approximately completed. Revision of older sheets has been begun.

~4 THE STATE GEOLOGICAL SURVEYS AND
Field work (chiefly reconnaissance) all over the State has afforded a
basis for checking and revising the bedrock geology map of Hitchcock
(18784.
Detailed local studies of rock structures, chiefly in connection with
highway projects or possible stone quarries for department or commercial
development have been carried on wherever such work seemed to promise
results. Several quarries have been located.
Hundreds of gravel samples have been collected, studied, and tested
by the Laboratory, and the relation of gravels to bedrock and glacial
geology has been brought clearly to the attention of state and town road-
builders. There has been quite a bit of pioneer research here.
The Geologist has frequently cooperated with the Testing Laboratory
in collecting representative sands, studying their mineral content, and
its possible relation to compression tests.
Studies have been made of highway subgrades, in relation to porosity,
frost action, etc. Data have been collected on brick clays, granite, mica
and feldspar, and other resources, but owing to economic conditions have
not been carried to the stage of publication or publicity.
The Geologist has cooperated with a special commission in securing
governmental aid in the study of coast protection at Hampton, and has
organized and collected rainfall data on mountains, during each summer
since the flood of 1927.
PRESENT MAIN LINES OF WORK
Since the new topographic quadrangles have been available, a detailed
field survey of gravel and sand deposits has been carried forward in all
parts of the State, and will soon be completed, showing location, extent,
and probable quantity and character of material available. An atlas for
the Commissioner showing these details is in preparation. This summer
will include a survey of fieldstone, as one of the future sources of road
construction on secondary highways.
The present activities of the Department Geologist are, as always,
quite varied. On the whole, they resolve themselves into giving attention
to any project on which geologic information is needed.
PREVIOUS SURVEY ORGANIZATIONS
There was no geological work in New lIampshire between the lIitch-
cock survey of 1878 and 1917.
