M. LILLEY, Staunton, Va.
This is instrument is semi circular plate, with
needle box attached to the diameter and the circular
edge graduated in degrees and there being nova
BILE limb adade attached to the centre of the plate
with verniers at both ends, the bearing of line
be read for any number of degrees or minutes
The plate is divided form. with the scale of
the aldade traverse table of lines instead of num-
bers which gives at the latitude and departure
of any course and distance run. IA
The table answers the same purpose for ascertain
ing heights and distances the required distance is
read from the plate without the trouble of referring
to the logarithmic tables.
1t gives the horizontal measurement of the lines of
survey and where there is local attraction the lines
be traced independent of the neede there being
two pair of sights, enabling the surveyor to form at
once the angle required by the bearings of the
The variation of an old line is easily calculated on
it, and for such work as leveng for mill-races or
draining land 1t answers every purpose of the level
There is an attachment for solving oblique TRAN
giles, which gives the base and perpendicular of the
triangle from which the area be ascertaned very
readily and it also gives the bearing and distance of
the closing line in division of land.
The instrument can be used with either the sights
or telescope. -r

The Surveying Instrument exhibited to me nv Col
Liley is combination of the Surveyors Compass with
protractor serving traverse table 1t gives at
the latitude and departure of any course and dis
lance run and has several other useful and ready an
plications in ordinary surveying.
The principles on which it works are verv obyous
and so far from being complicated it rather serves to
illustrate the nature of the survey Much labor ofca
cuahon and plotting NAV be saved by its use, and,
when well made and correctly graduated 1T will giye
reliable results. A. d. BAcHE, Supt q. 8. C
