34 INDIAN MARINE SURVEYS. 



had, in addition to the parent vessel's mileage, run some 11,500 

 miles of similar soundings. This total mileage, however, was far 

 from completing the shores of India. As a matter of fact, at that 

 time only 1,715 miles or one-third had been charted sufficiently for 

 safe navigation out of a total length of 5,100 miles, consequently 

 much remained and even now remains to be done before the coasts 

 of India can be said to be adequately surveyed. 



The localities specially needing attention have been specified in 

 a very valuable memorandum by Commander Carpenter, which is 

 attached to the Marine Survey Eeport for 1888-89, and a brief 

 notice of these requirements is here desirable, and will form a fitting 

 conclusion to the present chapter. 



The mouths of the Indus have not been examined since 1877, 

 when they were surveyed by Lieutenant A. "W". Stiffe, and are 

 continually reported to be shoaling seaward. A re-survey will 

 have to be done astronomically with a mark boat as a guide to the 

 line of soundings. The original survey was made as far back as 

 1848-49, and the examination in 1877 was only over the most 

 projecting portion, which, however, is that which most specially 

 requires attention from time to time. 



The Gulf of Cutch shows signs of increasing trade, and before 

 long the ports of Mundra, Tuna, Eojhi, and Salaya creek will require 

 charting on scales sufficiently large for harbour improvements. 

 The gulf was well surveyed for open navigation in 1852 by 

 Lieutenant (now Commander) A. D. Taylor.* but the plotting on 

 the chart requires fitting in with the land triangulation. 



The coast of Kathiawar from Dwarka point to Gogha in the 

 Gulf of Cambay is fairly well shown, and an improved chart to 

 Diu head is to be compiled, but Jafrabad, between Diu and 

 Goapnath, requires charting on a large scale, and the whole coast 

 needs sounding off. It was surveyed by Lieutenant Ethersey, I.N., 

 in 1837, in a pattimar. The operations now called for would occupy 

 two years. 



The Gulf of Cambay is practically unsurve} r ed, with the exception 

 of a portion from Bhaunagar creek down to Perim island and 

 across to Broach, which represents about one-seventh of the whole 

 area. The head of the gulf is shallowing up and becoming less 

 navigable every year, and this is resulting in the banks at its
