Departure from Monte Video--Port Santa Elena--Geological remarks--Cape Fairweather--Non-existence of Chalk--Natural History--Approach to Cape Virgins, and the Strait of Magalhaens (or Magellan) We sailed from Monte Video on the 19th of November 1826; and, in company with the Beagle, quitted the river Plata. According to my Instructions, the Survey was to commence at Cape San Antonio, the southern limit of the entrance of the Plata; but, for the following urgent reasons, I decided to begin with the southern coasts of Patagonia, and Tierra del Fuego, including the Straits of Magalhaens.[4] In the first place, they presented a field of great interest and novelty; and secondly, the climate of the higher southern latitudes being so severe and tempestuous, it appeared important to encounter its rigours while the ships were in good condition--while the crews were healthy--and while the charms of a new and difficult enterprize had full force. {2} Our course was therefore southerly, and in latitude 45° south, a few leagues northward of Port Santa Elena, we first saw the coast of Patagonia. I intended to visit that port; and, on the 28th, anchored, and landed there. Seamen should remember that a knowledge of the tide is of especial consequence in and near Port Santa Elena. During a calm we were carried by it towards reefs which line the shore, and were obliged to anchor until a breeze sprung up.
