The great value of the levels with Stadia points in taking discharges will
be referred to in the next Chapter; they
stadia level* and Berthon boats. were a l s0 of great service in carrying lines
of levels through tamarisk thickets, and over bad ground where it was very
difficult to chain with any accuracy.
The Berthon boats were also of very great value in taking cross sections of
rivers and getting across flooded lands, and the work could not have been
carried out effectively without them.
Every levelling party should be provided with a plane-table to sketch in
detail along the traverse line and thus add greatly to the value of the levels.
A Survey of India pattern clinometer should be supplied with the plane-table
for making rough cross sections.
For work across waterless tracts water was taken in pakhal ; large leather

side of a camel. The only convenience of a
pakhal is that when empty a dozen or twenty can be loaded on to one camel,
and thus transport is economised. This "said their merits are disposed of;
and only a long list of disadvantages remains to be recorded. We found, just
as the Russo-Afghan Boundary Mission of 1884 discovered, that mushak^ i.b.)
goat skins, are much more reliable and satisfactory. When crossing the desert
to Khw&ja ’Ali they were supplied with water by the Afghans, who brought it in
mushak from the river; their own pakhal brought from India leaked and were
useless. In building the boundary pillars we bought up all the mushak that
were to be bought, and could only get enongh to load half a dozen camels. The
mushak is water-tight and handy, but the supply available is small, and they are
: cfiffi 011 ^ to get in India as in Seist&n ; in Sukhur in December 1902 only
about 30 could be bought ; they were obtained from the milk-sellers, who use
them as floats for swimming the Indus to their herds on the islands.
1 J he t°t khal sh ?uld be made by experienced men (preferably bhisties) of good
: leather, and sewn with a needle of smaller size than the thong used, otherwise
the seams will always leak. The pakhal must be soaked for some days before
1 is used, and must never be allowed to dry while in use. Goat’s fat is the best
