Surrey autumns invest the shingled spires of these Wealden churches with a peculiar beauty. Grey and white, black-streaked and shining, weatherbeaten and weather-conquering, there is nothing in architecture lighter or more graceful than the patterned sheaths of native oak surmounting belfries which, sometimes for centuries, have called the villagers to church. But in late autumn, when the swallows and martins are practising starts for their long journey, the shingled spires turn themselves to fresh uses. On a sunny day the birds come about them in scores, pressing their bodies flat against the warm, dry wood, darting out for short flights, hawking gnats and midges, and flitting back again, keeping up through it all the sweetest and gentlest of anxious twitterings, and, when they are clinging to the chequered wood, resembling it so closely in colour and texture as to make it hard to count a dozen birds quickly. Martins near their time for going enter on all kinds of engaging habits, especially just before and just after dusk, when bands of a dozen or so seem suddenly to make up their minds to trial flights of the most amazing speed, utterly unlike their ordinary, quiet flittings. But there is nothing prettier in all the pageant of the migrants' year, than a dozen score martins with the unrest of autumn on them darting round a shingled spire.

Four castles stood along the ridge of the Surrey downs when the barons were at war, and of the four nothing worth the name of a castle remains. Farnham's keep was broken down by Cromwell: Guildford is a shell, Reigate and Bletchingley have disappeared altogether. Betchworth, never fortified for war, was built later than the others, but Betchworth is an insignificant ruin. The kings and the captains have passed, and their buildings have followed them. The castles have gone down with the palaces. Surrey never had a castle like Arundel; but she has not been able to keep even a Pevensey or a Bodiam.
