Narrative of the surveying voyages of his majesty's ships Adventure and Beagle (vol.2- Appendix): between the years 1826 and 1836 : describing their examination of the southern shores of South America, and the Beagles's circumnavigation of the globe

APPENDIX. 177 round, and some oval, but all green when taken out of the maw yet by long keeping they turned of an ash colour." No. 25. By Robert FitzRoy, Captain of H.M. Surveying Sloop Beagle. You are hereby required and directed to take charge and command of the schooner Constitucion, and the party placed by me under your orders. Directly the vessel is ready for sea, you will proceed to survey those parts of the coast of Chile which lie between the parallels of thirty-one and thirty -five : and on or before the 3 1st of July, you Avill endeavour to meet me in Callao Roads.

At many places the landing will be bad. Do not on any account land then in a boat. Go near only in a boat ; land on a balsa. On so straight a coast, subject to a continuance of cloudy weather, views of the land may be particularly useful. Mr. King is added to your party, because he draws such views very correctly. Do not delay in attempting to get deep-sea soundings, when not hove-to for other purposes. Be very particular in noticing characteristic appearances of the land about anchorages ; and such peculiarities of marks, or other- wise, as may help to guide a stranger. Notice where and how wood and water are to be procured. Let Mr. King keep a journal for you, to be given afterwards to me. No log will be required by me ; but let that journal contain every note which you consider likely to be useful. I shall be anxious to send away a tracing of your work, as soon as possible after your arrival at Callao. Remember that Paposo is the northernmost inhabited place over which the government of Chile has authority. In approaching vessels or places on the coast of Peru, be particularly on your guard. Inquire about the earthquake and waves of the 20th of February. At each place make the chief Authority acquainted with your busi-
