was an increase in the sale of Admiralty publications, and of charts 

 of Indian ports and anchorages. Many acknowledgments were 

 received from the maritime public of the practical utility of an office 

 where reliable charts and information were procurable. 



Seventeen new charts were issued during the year referred to, 

 and the large number of 17,268 Admiralty and Marine Survey 

 charts corrected. Among the special reports prepared during the 

 year, and reprinted in the Annual Report, were the following : —

 It contains some useful observations and suggestions in regard to 

 92 lights, from Karachi to Coco islands. A supplementary report 

 in the same volume deals with the question of the relief and supply 

 of Indian lighthouses and their periodical inspection. 



Owing to the untimely death of Mr. Morris Chapman, I.N., the 

 temporary abolition of No. 2 Boat party, and the postponement of 

 the surveys of Beypur and Cochin had become necessary ; and as 

 Lieutenant Jarrad's health was impaired, arrangements were made 

 for him to remain at Bombay and for an amalgamated party 

 under him and Lieutenant Petley to take up the survey of the Bombay 

 harbour, which the experience of the previous year had shown to 

 be necessary. 



The first survey undertaken, however, was that of Karwar, which 

 was plotted on the 6-inch scale by Lieutenant Petley ; but owing 

 to the inefficiency of the small steam cutters at the disposal of the 

 party, the survey could not be extended so far to the north and
