the 29th of August, there was an earthquake on shore, which 

 was felt by those- of the party who were afloat — the vessel ap- 

 pearing to receive a severe shock. September 5th, Captainr 

 Crisp, with Mr. Lawrence, proceeded to the island of Pulo- 

 Bauka, near the north-east extremity of Tappanooly bay, and 

 afterwards to the remarkable island, called the Sugar-loaf Peak; 

 sights for the longitude, and bearings, and angles were taken ; 

 and they returned to Tappanooly, about sun-set. 9th, Mr. 

 Lawrence proceeded for Battoo Barroor Point, for the 

 purpose of laying down its position, and the prominent- 

 points of the Mansellar Islands, together with some points oF 

 Tappanooly bay. The brig Eleanor returned on the 11th from 

 Pulo Panjong. 12th, all the baggage was sent on board the 

 brig, and the remainder of the party embarked at sun-set for 

 Pulo Panjong, where they arrived on the 16th : observations, 

 were commenced by Mr. Lawrence on the following day at a 

 station near the Resident's house. On the 18th, the Eleanor 

 sailed for Bencoolen for another supply of materials for the. 

 pillar. September 19th, Mr. Lawrence proceeded, with Cap- 

 tain Crisp, to Pulo Telloor, where observations for the latitude 

 and longitude were taken, and also angles of the adjacent 

 islands, and that part on the coast between points Kurboyee 

 and Lubwaun Looloo — returned late at night. Another excur- 

 sion made on the 23d, to Pulo Pahgaugo, for the purpose of 

 laying down its position ; and it was intended to have proceeded 

 thence to the other islands near the equator, but the winds aiajd. 

 weather having been very unfavourable, they were obliged, to 

 return on the the 25th to Pulo Panjong. On the 26tb, they 

 ventured out again for Nattal, but returned the following 

 day. On the 29th, at night, Captain Crisp in one boat, and 

 Mr. Lawrence in another, sailed for Nattal, and proceeded to* 

 gether as far as Pulo Tamang, where, early on the 2d of Oc- 

 tober, the boats separated, the one with Captain Crisp pro- 

 ceeding round the west side of the island, and the other takino- 

 a direct course for Nattal — the weather and winds bein(y unfa- 

 vourable, the latter strong with a heavy sea — the boat with 

 Mr. Lawrence returned to Pulo Tamang — and on the 3d sailed 

 again, but was obliged to proceed to the Sumatran shore for pro- 

 visions, and anchored in the river at Patamm. — Next day, the 

 4th, having heard no inteUigence of Captain Crisp, Mr. Law- 

 rence wrote to the Resident, and received a reply late on the 

 5th, stating that Captain Crisp had not arrived at Nattal, ami 

 advising Mr. Lawrence to return to Pulo Panjong — the weather 

 very unfavourable at the time for vessels of any description to- 

 proceed to the northward. At sun-rise on the 6th, they sailed,^ 

 however, for Pulo Panjong, and fortunately arrived in the after* 

 noon, Captain Crisp having also returned. On the 4th, at 10
