Of the many well-known passages between the innumerable islands of that great Archipelago, there is not one which has ever been charted with plausible accuracy; and it cannot be too strongly impressed on your mind that hydrography is better served by one accurate chart than by ten approximate sketches.
The several objects of this highly interesting expedition having thus been briefly enumerated, I have only to remind you that their Lordships do not prescribe to you the order in which they are to be executed, leaving it to your own prudence, and to your experience in those climates, so to arrange them that each part of your survey shall be complete in itself, and that each step in your progress shall be conducive to its successor.
Signed: F.BEAUFORT, HYDROGRAPHER.

SAIL FROM PLYMOUTH.
The Rattlesnake left Spithead on December 3rd, and on the 11th took her final departure from Plymouth, which place we had called at to complete her fittings, swing the ship a second time to ascertain the amount of local attraction, and receive some specie for the Cape of Good Hope and the Mauritius.

Being favoured by strong northerly winds, we reached Madeira on December 18th, after a quick, but most uncomfortable passage; during the greater part of which the main and lower decks were partially flooded, owing to the inefficiency of the scuppers, and the leaky state of nearly every port and scuttle in the ship.
ARRIVE AT MADEIRA.
December 20th.
The scenery of Madeira has been so often described by voyagers, who, from Cook downwards, have made it the first stage in their circumnavigation of the globe, as to render superfluous more than a few passing allusions.
When near enough to distinguish the minor features of the island, the terraced slopes of the mountainsides converted into vineyards and gardens studded with the huts of the peasantry, presented a pleasing aspect to visitors, whom a week's sailing had brought from the snow-clad shores of England.

Here and there a whitewashed chapel or picturesque villa lent a charm to the scenery by contrasting strongly with the patches of green upon the slopes, the deep blue of the ocean, and the delicate white of the ever-changing clouds of mist which rolled incessantly along, while the rugged summit of the island, and the deep ravines radiating towards the coast-range of precipitous cliffs, gave an air of wildness to the scene.
FUNCHAL.
The town of Funchal, said to contain about 25,000 inhabitants, is situated upon the slope of an amphitheatre of hills, behind the only anchorage of the island.

The finest view is obtained from the balcony of a church dedicated to Nossa Senhora de Monte, situated at a considerable elevation above the town.

Here one looks down upon the numerous quintas and cottages of the suburbs embosomed in gardens and vineyards, the orange groves and clumps of chestnut trees, the snow-white houses of Funchal with its churches and public buildings, the citadel frowning over the town, the calm waters of the bay with the vessels at anchor gently heaving to and fro on the long westerly swell, the Ilheo rock and batteries, the bold headlands, and the dim outline of the distant Desertas.
