2 INDIAN MARINE SURVEYS. 



the survey during the year 1876-77. The Admiralty chart of 

 Tavoy river was also found to be very erroneous, but during a brief 

 stay Commander Taylor was enabled to take observations and 

 soundings which resulted in a more reliable chart being pro- 

 duced. At Junkseylon he met Captain A. de Richelieu, Siamese 

 Royal Navy, commanding the gunboat " Coronation," from whom 

 an excellent preliminary survey of that island was obtained, and 

 published at Calcutta.* 



In July Commander Taylor proceeded, with Navigating Sub- 

 Lieutenant E. W. Petley, R.K, to False Point to report how the 

 sum of Rs. 30,000, applied for as a loan to the Port Fund, could best 

 be spent in the interests of the port. On this an elaborate report 

 was submitted to Government. In the following March he was 

 deputed to Goa with instructions to visit the harbours of Karwar 

 and Marmagao and report on their relative merits as shelter-giving 

 anchorages during the S."W". monsoon. On careful consideration, 

 Commander Taylor came to the conclusion that Marmagao was 

 superior as a natural harbour, and in some respects as regards the 

 practicability of making improvements quite equal to Karwar. Two 

 officers, Xav. Lieutenant Jarrad, R.X.. and Mr. Falle, were sent to 

 survey Madras roadstead, and a careful sectional survey of the 

 part of the roadstead and beach abreast of the native town was 

 commenced by them and continued by Lieutenants Hammond and 

 Pascoe on the scale of 600 feet to 1 inch. 



Lieutenant Jarrad's next work was to connect, astronomically, 

 Diamond Island, Rangoon, and Amherst Pagoda, the three principal 

 stations in the Gulf of Martaban essential to the reproduction of 

 a new chart of that locality. An elaborate sectionally sounded 

 double elephant sheet survey of Moulmein river approaches was 

 excellently carried out, comprising 10.3 square miles of water 

 closely examined, and 36 miles of coast trigonometrically laid 

 down. An important correction of the true bearing of Double 

 Island lighthouse from Amherst point was obtained by Lieutenant 

 Jarrad, who discovered the former to be If miles westward 

 of its true position, notwithstanding that it had already been 

 shifted a distance of 4J miles to the eastward of the positions 

 shown on the Admiralty charts. His next step was to commence a
