Although there is little of beauty in the quarries that honeycomb the hills to the west of Swanage, the industry that is carried on is of much interest as a surviving guild or medieval trades union. One of the laws of the "company," unbroken from immemorial time, is that no work may be given to any but a freeman or his son who, after seven years' apprenticeship, becomes a senior worker upon presenting to the warden a fee of 6_s_. 8_d_., a loaf of bread and a bottle of beer. The guild meet every Shrove Tuesday at Corfe to transact the formal business of the year. Each quarryman and his partner, or partners, hold the little independent working allotted to them apart from the remainder of the quarry. This obviously prevents blasting and each block of stone is cut out by manual labour. [Illustration: TILLY WHIM.] Purbeck marble is famous all over southern England, and many historic buildings, from the Temple church in London to Salisbury and Exeter Cathedrals, are enriched by the beautifully polished columns of this dark-coloured limestone. The caves at Durlston, with their intriguing name, are simply abandoned quarries, although all sorts of fanciful legends have grown up about them. To any one familiar with the plan of the working of a quarry, the sloping tunnel that gives access to the cave will prove the origin to be artificial. Nevertheless, Tilly Whim is romantic enough to please the most fastidious of the steamer contingent and the scene from the platform of rock in front of the old workings is as wild and natural as could well be imagined. As for the open-air schoolroom above on Durlston Head a description is hardly necessary. That the pedagogic master mason was not without the saving grace of a sense of humour is proved by the once plain block of stone provided for those who would perpetuate their own greatness, now literally covered with names and initials. The staring red and white "castle" that crowns the cliff is a restaurant built to accommodate the day visitor, but if the evidence of discarded pastry bags and ginger-beer bottles that at times litter and disfigure the cliff and caves is to be regarded, the castle is not as well patronized as it should be. This unseemliness is kept under by what appears to be a daily clean up, though the writer has never met the public benefactor who makes all tidy in the early morning hours before the steamers have discharged their crowds. Possibly this is the same individual who keeps the tangle of blackberry and tamarisk pruned down so that while resting with "Sir Walter Scott" or "Shakespeare" we may duly admire the view across Swanage Bay.
