We set off after leisurely breakfast, and had a very pleasant cruise, in nice weather and the odd lock. We came across a swan family just before our possibly overdue lunch, as we were coming in to moor for it. This family had an accompanying man, who explained to us that one of the cygnets had a fishing line with float, stuck in or possibly beside its beak. This looked at least uncomfortable, and this cygnet was shaking its head slightly more than the others were, we thought, and seemed to lead small waves of reciprocal head shaking, we felt. But the situation certainly looked unhealthy. The man was trying to sort it out, but was having a bit of bother with stage one, which was getting that cygnet, of the seven, to come near, and the parents not to come near. He was giving lots of feed type pellets, having too much attention from both parents, and having not much success at attracting the relevant cygnet. Various potential cygnet-catching and adult swan repelling tools at hand on Bartimaeus were discussed (variety of bags, rope, mushroom box, boat hook) and were ruled out before … or after … application. In the meantime we contacted a wild animal rescue centre, ultimately to no avail on this occasion, and in the meantime the float part was visibly dangling lower than before, and the swans and man moved away, and the rest of us being very hungry, got on with lunch. Man came back after about 20 minutes, reporting that he had freed cygnet (!) and showing us the fishing line with float (no hook, (hook stuck in skin had been a part of all of us’ worry)) and with some water weed stuck on one end which had been all the way down its gullet.
