I No. 30. By Robert Fitz-Roy, Captain of His Britannic Majesty's Surveying Sloop Beagle. You are hereby required and directed to take upon yourself the charge and command of the schooner Constitucion (tender to the Beagle), and all on board of, or belonging to her. As soon as you axe ready for sea, you will proceed to that part of the coast of Chile, near the Desert of Atacama, at which the survey of Lieut. B.J. Sulivan ended. From that part you vnU coast along and survey the shores north- ward towards Callao, and thence toward Puna, near Guayaquil. At Puna your survey is to terminate. You win thence return to Callao in the schooner Constitucion, or you will sell the said schooner, and, with your party, make your way to Callao, by the means which you consider best for his Majesty's service : combining economy with efficiency. If opportunity should offer, a measurement from Puna to the Gala- pagos woiild be very desirable.
