Presently the work of transfer was ended, the tenders cast off, and at 1.30 P.M., with the screws churning up the sea bottom again, the Titanic turned slowly through a quarter-circle until her nose pointed down along the Irish coast, and then steamed rapidly away from Queenstown, the little house on the left of the town gleaming white on the hillside for many miles astern. In our wake soared and screamed hundreds of gulls, which had quarrelled and fought over the remnants of lunch pouring out of the waste pipes as we lay-to in the harbour entrance; and now they followed us in the expectation of further spoil. I watched them for a long time and was astonished at the ease with which they soared and kept up with the ship with hardly a motion of their wings: picking out a particular gull, I would keep him under observation for minutes at a time and see no motion of his wings downwards or upwards to aid his flight. He would tilt all of a piece to one side or another as the gusts of wind caught him: rigidly unbendable, as an aeroplane tilts sideways in a puff of wind. And yet with graceful ease he kept pace with the Titanic forging through the water at twenty knots: as the wind met him he would rise upwards and obliquely forwards, and come down slantingly again, his wings curved in a beautiful arch and his tail feathers outspread as a fan. It was plain that he was possessed of a secret we are only just beginning to learn--that of utilizing air-currents as escalators up and down which he can glide at will with the expenditure of the minimum amount of energy, or of using them as a ship does when it sails within one or two points of a head wind. Aviators, of course, are imitating the gull, and soon perhaps we may see an aeroplane or a glider dipping gracefully up and down in the face of an opposing wind and all the time forging ahead across the Atlantic Ocean. The gulls were still behind us when night fell, and still they screamed and dipped down into the broad wake of foam which we left behind; but in the morning they were gone: perhaps they had seen in the night a steamer bound for their Queenstown home and had escorted her back. All afternoon we steamed along the coast of Ireland, with grey cliffs guarding the shores, and hills rising behind gaunt and barren; as dusk fell, the coast rounded away from us to the northwest, and the last we saw of Europe was the Irish mountains dim and faint in the dropping darkness. With the thought that we had seen the last of land until we set foot on the shores of America, I retired to the library to write letters, little knowing that many things would happen to us all--many experiences, sudden, vivid and impressive to be encountered, many perils to be faced, many good and true people for whom we should have to mourn--before we saw land again.
