St Luke’s Church by the way, you know on Bold Street that was a major navigation point. This is the Liverpool docks and on this wall would be all the compass readings painted in massive big letters ’20 degrees’, ‘30 degrees’, ‘40 degrees’, North, North West or whatever it was. While the ship was passing they’d take a reading of St. Luke’s which is in line with the reading on the wall, you could see it perfectly straight. Then at the same time the prism gives them a reading onto the compass card, so you’d look there, get right in line, look down and there’s your reading. Say, on the compass card, through the prism they’d be say 021 degrees you’d see and then they’d line that up with the wall and the wall would have the same. So that’s how you took a reading from that distance.
