MAGNETIC SURVEY OF TASMANIA. 789 
Azimuths.—Right edge of a rock on Mt. Roland (see 
figure III., plate II.), A, 30° 8’ 46". Spike on gable of 
weatherboard house, 6, 76° 31‘ 39". 
Magnetic station from M.S. mark.—Distance, 102-6 feet, 
azimuth, 76° 31' 39". 
Directions for findmg M.S. Mark.—Buried. Proceed east 
from Latrobe towards Deloraine, along the main road, till 
the west boundary-fence of the racecourse recreation reserve 
is arrived at. Measure north along that fence (from S.W. 
corner) a distance of 430 feet 8 inches. From the point on 
the fence so reached measure exactly at right angles to the 
fence (towards the east) 112 feet 4 inches. The M.S. mark 
is at the point so found. In November, 1902, on uncovering 
the concrete block, it was found broken, and the Muntz 
metal mark had been removed. The square plan of the 
block was, however, quite plain.

Considerable, difficulty was experienced at this station in 
finding a site which, while geologically suitable, would permit 
of observations of ithe azimuth of a distant object of a per- 
manent nature being taken. The site finally selected is 
some few miles east of Stanley, beyond the Black River. 
The underlying rocks are indurated sandstones and schists. 
probably of older Paleozoic age. 
Azwmuths.—Telegraph wire insulator, a, 1219 23! 11,", 
Cairn on Nut, B, 179° 8‘ 26''; c, (described below in the 
““dtrections’”’), 2379 8' 26. 
Magnetic station from M.S. mark.—Distance, 14-6 feet; 
azimuth, 301° 23' 117’, 
Directions for finding M.S. mark-—Buried. Proceed 
from Stanley towards Wynyard to the small creek (f in the 
figure, plate III.) 0:76 mile beyond the middle of the Black . 
River bridge. X,Y, arecottages. T,, I',,ate telegraph posts 
on the north side of the road; T,,1,, T',, telegraph postson 
the south side. c,d are two stout wooden pegsa chain apart, ¢ 
being directly under the telegraph wire and d close by road.
