“QLieutenant Melville, commencing in the north of Zanskar (or 
Zaskar) surveyed a large portion of it, including all the large glaciers, 
to the west, as well as those, at the head of the Butnai river. Some 
of these glaciers were 15 to 7 miles in length. Total progress very 
good, and with the trigonometrical points now available he will be 
able to complete the sketch of Zanskar during the ensuing season. 
Whilst surveying, Lieutenant Melville made some very successful and 
characteristic photographs of glaciers, and of the country generally.” 
7. The Coast Szrtzes,* between Calcutta and Madras was placed 
under the superintendence of Captain Basevi, Bengal Engineers, in 
the autumn of 1860, the exigencies of the department having requir- 
ed his transfer from the Trans-Indus frontier all the way to the 
Madras Coast.—His operations commenced in the vicinity of Vizaga- 
patam, and were proceeding towards Rajahmundry, when on approach- 
ing the hill of Kapa in the Rampa estate, he found that his signallers 
had been driven away from the hill with threats of violence, and that 
the inhabitants of the district were assembling to prevent him from 
ascending. The estate is rent free, and the people are a lawless set, 
though under the control of the Godaveri Magistracy. Captain 
Basevi, having obtained an extra Military Guard and a body of Po- 
lice, made his way to the summit of the hill without molestation, 
and took the necessary observations. One day, the people set fire to 
the grass on the hill, which was about 8 feet high, and a Rajah 
brought intelligence that they were collecting to attack the Survey- 
ors; but the fire was extinguished, and the attack was not attempted. 
Captain Basevi’s chief apprehensions were for the signallers, whom he 
had to leave behind at the station, but a guard was left with them, 
and they were unmolested. 'The only serious inconvenience occasion- 
ed was in having to construct the station on a block of laterite sever- 
al feet below the hill, for the summit was covered with dense jungle 
* On the Coast Series, the principal operations consist of 42 triangles, arrang- 
ed so as to comprise one double and five single polygons, and one quadrilateral. 
Twenty-one triangles were measured during the first season with a 2-foot Theo- 
dolite by Barrow, giving a mean triangular error of 0”.65, and an equal number 
measured the next season, with a similar instrument by Troughton and Simms, 
gave a mean error of 0”,37,—Azimuthal observations on Circumpolar Stars were 
taken at three stations.
