The church is a very fine Perpendicular building, of a warm rose colour, and it has a high battlemented tower from which three figures look out of their niches. Some very grotesque gargoyles peer down from the roof at intervals. The great treasure of the church is its screen, carved so finely that the pattern seems like lacework, and it is difficult to realize that it can be of stone. The main lines of the carving curve and spread upwards almost like the lines of palm-leaves, and the screen is coloured and gilded. There is another beautiful and delicate, though less elaborate, bit of carving which divides a little chapel from the south side of the chancel. Under the tower arch is a curious monument to Christopher Blackhall, who died in 1635, and his four wives, who are kneeling one behind the other. The dates of their deaths are very clearly marked by the different fashions of their dresses--a compact and upstanding ruff adds to the stiff precision of the first wife's appearance; while the sloping lines of a 'Vandyke' collar embellish the dress of the fourth. On the north side of the church stands the old Guildhall, and in front of it another tiny piazza, bordered by granite pillars. Inside 'linen-pattern' panelling lines the walls; there are carved seats all round the upper end, and in the council-chamber beyond are some fragments of fine moulding. Before leaving the town, a curious custom practised in the eighteenth century must be mentioned--that of taking dogs to help in catching salmon. Defoe came here in his travels in the West, and saw the fish being caught. The fish, he says, in the flowing tide swim into a 'cut, or channel,' which has a 'grating of wood, the cross-bars of which ... stand pointing inward towards one another.... We were carried thither at low water, where we saw about fifty or sixty small salmon, about seventeen to twenty inches long, which the country people call salmon-peel,' caught by putting in a net at the end of a pole. 'The net being fixed at one end of the place, they put in a dog (who was taught his trade beforehand) at the other end of the place, and he drives all the fish into the net, so that, only holding the net still in its place, the man took up two or three and thirty salmon-peel at the first time.' He finishes the story by saying that they bought some for dinner at twopence apiece. 'And for such fish, not at all bigger, and not so fresh, I have seen six and sixpence each given at a London fish-market.'
