Progress of the State Geological Survey,
An Abstract of the Summers Work.

an Abstract OF the Summers Work.
The following abstract of Prof j. p.
Lesleys report to the board of commits
sioners at their meeting on the 4th instant,
viii give the public good idea of what the
survey corps has done during the summer
DIR. I. Sterry Hunt, appointed at the
last meeting of the board to report on the
traps and allied rocks, pursued his survey
between Easton and Chambersburg in
August and September, returned to Boston,
and will present his report in due time
after making further researches.
Mr.. MCreath has finished all the
analysis of 1874, and has made good pro-
gress in the analysis for 1875
Mr. Allen has travelled through the state
collecting and arranging data. for our vol
ume of railroad and other levels, and has
connected them with the levels of surround
ing states.
DIR. Genth has pursued his chemical stu
dies of minerals and rocks, and is at present
entirely occupied with nice and difficult
analysis of the waters of our mineral
springs.
Dr. Genth and Mr.. McCreath answer all
mineralogical inquiries made by citizens of
the state.
DIR. Lcsquereux has examined the collec-
tions of fossil plants in vrrious places and
is now writing descriptions and making
drawings, for the volume which will con-
tain his report. 1t is to be a handbook
for Pennsylvania and for the United States
EASTERN PENNSYLVANIA - LIMESTONE
IRON ORES.
Prof Prime, aided by Dr. Clarke and
Mr. Kent, has completed the limestons belt
of Lehigh county and will finish the lime
stone belt of Northampton county, before
snow falls. We shall then have complete
contour-line map, with all ore banks, ore
shows, limestones and outcrop exposures
from Alburtis to the Delaware river, with
special studies Of the larger mines.
SOUTH PENNSYLVANIA GEOLOGY AND
ORES.
Prof Frazer, aided by Mr. Lehman, and
Mr.. Edwards, has made section SURVEYS
across the South mountain, and will soon
have completed the first draft Of complete
contour-line map of the mountain mass
from side to side, and for five or six miles
north and south of the Gettysburg Cham
bersburg pike. Mr.. Frazer's district is the
most difficult in the state, as yet occupied
Much of his time has been spent in revising
his sections across York county, prepara-
tory to printing his first report of progress,
which therefore includes a good deal of
1875. DIR. Hunts knowledge of the rocks
in New England and Canada has been of
service in helping to explain some of the
difficulties &; but most of them are inherent
in the region itself and can only be worked
out in detail instrumentally, by the party.
CENTRAL PENNSYLVANIA, MAPS, GEOLOGY
AND FOSSIL ORES.
Mr. Devices has continued his survey of
every opening along the entire extent of
the fossil ore outcrops and he has nearly
finished all that lies in Union, Mif1in, Ju-
niata and Huntingdon counties, from
Selinsgrove, on the Susquehanna, to the
south end Of Black Log mountain, 4. e. the
entire length of Jack mountain and Shade
mountain, with the intermediate lines.
His report will be large, carefully made and
exhaustive.
Mr. Billen and Mr. Ashburner, Mr. De
wees aids, have been making a special sur
vey of Auchwick valley, from Black Log
Gap and Orbisonia, around the end Of
Jacks mountain, over Sideling Hill and
through Sideling Gap to Broad Top. Con-
tour lined maps and cross sections are in
various stages Of completion, and will soon
be ready for printing. They are now map
ping and studying the East Broad Top coal
basin, and Will connect it with my own
large unpublished map Of Broad Top made
some years ago, so that the whole can be
published next year.
WESTERN PENNSYLVANIA - GEOLOGY,
COAL MINES, NATURAL GAS AS FUEL.
Mr.. Platt, with the aid of his brother
Mr.. G. c. Platt, has made complete sur
vey of Cambria county, locating and de-
scribing every coal opening. He has half
finished Somerset county, and expects to
finish the whole kefore winter. His re-
port of these two counties will be similar
to his last years report on Clearfeld and
Jefferson. Mr. Young is now aiding him
into suthern Somerset.
Mr. Young, under Mr. Platt's directions,
has made coke and coal survey of the
Youghiogany and Monongahela valleys,
from Connellsville to Pittsburgh and will
have ready for the press early this winter,
large and important report on the same.
In this he will have the concurrence of Mr.
Fulton's studies Of the coke question for the
