"The Atlantic Telegraph fleet sailed from Queenstown, Ireland, Saturday, July seventeenth, and met in mid-ocean Wednesday, July twenty-eighth. Made the splice at one P.M., Thursday, the twenty-ninth, and separated--the Agamemnon and Valorous, bound to Valentia, Ireland; the Niagara and Gorgon, for this place, where they arrived yesterday, and this morning the end of the cable will be landed.
