Mr., Chance has mapped the Dela-
ware and Lchigh Water Gaps, and
constructed sections through the roof
ing slate belt, hydraulic lime and glass
sand formations. Mr.. Hall, after ar
ranging the cabinet ofiossils, examined
the fossil localities in Westmoreland,
Warren and vcnango counties and in
the Juniata district, spent month
with q volunteer party Of collectors on
the Lohigh and Delaware rivers.
The number Of analyses called for
by the assistants to illustrate their re-
ports demanded an increase of force in
tho laboratory at Harrisburg Mr..
Ford has therefore been employed us
assistant, which will double the capaci-
ty of the laboratory turning out work.
RAILROAD LEVELS.
Mr.. Allen, attached to Mr.. Frazer
last year, has been detailed for special
service, viz Tho collection and man
agement Of all the railroad and canal
levels in the State. lie will have for
publication in the winter, several
thousand levels at fixed stations on
railroad, canal and turnpike lines
This is not only necdful for the work
of the survey, but excites great interest
among engineers apd surveyors. 1t is
the intention to include in the list,
alphabetically arranged, all stations
leveled by the survey corps.

wieldly volumes Of geological surveys
they are Of very convenient, handy
size, printed on good paper, in cleal
type, and the workmanship reflects cred
it on the Stateprintcr. They are stcre
otyped, so that editions can bo pub
lished at any time to meet the demand

unusual fullness; each is sold sepa
rately, and persons who get them a.

excellent feature of this survey, as
/, there are really no preliminary reports
to be thrown aside and superseded by

drawing and finishing to secure th'
best appearance for the books, and {
great deal of correcting, amplifyinl

worker.

the geological reports, but the worl
of publication is, in fact, much NOR,
advanced than was ever the case will
any other geological survey in thu
same time There is no question bu
the general result will be satisfactory
to the people of the State and thu
scientific world.
