If, after the return of the Adelaide, you should find the weather so favourable as to permit your extending your exploration of those parts of the Strait which are yet unknown to us, you will remain for that purpose; but, at all events, you are to leave the Strait by the middle of June, or the first of July at latest, and repair with the Adelaide to San Carlos, at the north end of Chilóe, where you will find or hear of me, by the 10th of August.
In performing the above orders you will act as you may consider best for their most effectual execution, keeping in mind that the most desirable part is the survey of the Magdalen Channel.
From our experience, last year, of the weather during the months of April and May, I am in hopes of your being able to work during those months, with success; but should you meet with bad weather, you will be most careful in not exposing your people unnecessarily to the severity of the climate.
Upon detaching the Adelaide you will appoint Lieutenant Skyring to the superintendence of the service upon which she is sent, giving Lieutenant Graves instructions to that effect accordingly.

His Majesty's surveying sloop Beagle, Port Famine.
| Sir; | April 19, 1829. |
In obedience to the orders I have received from Commander Phillip Parker King, senior officer of the Expedition for the survey of a part of South America, it is my direction that you proceed immediately, in the Adelaide schooner, to survey as much of the Magdalen Channel and the Strait or Channel of Santa Barbara as you find practicable at this season of the year.
