The Lusitania's Last Voyage - Being a Narrative of the Torpedoing and Sinking of the R. M. S. Lusitania by a German Submarine Off the Irish Coast May 7, 1915 #226173

Friday noon (may 7) we made only 462 miles. This was partly accounted for by the fact that we picked up Greenwich time at Cape Clear and put the clock ahead 1 hour and 40 minutes. The reason this small run impressed itself upon my mind was that I expected that when we sighted the Irish Coast the Lucy would show a burst of top speed and that we should go flying up at not less than Q5 miles an hour. The run up to Thursday noon (may 6) had been 484 miles, and so confident was I that she would put on steam that I bought the high number in the pool (for Friday), which was 499. It was the only pool I went into and I couldn't help it, for the number sold at and at that price it looked like a bargain.
