A prominent feature on the mainland as seen from Brownsea is the little Early English church of Arne, standing on a promontory running out into the mud-banks of the estuary, and terminating in a narrow tongue of land known as Pachin's Point. At one time Arne belonged to the Abbey of Shaftesbury, and it is said that the tenants of the estate, on paying their rent, were given a ticket entitling them to a free dinner at the Abbey when they were passing through Shaftesbury. The vast size of Poole Harbour is realized when we consider that, excluding the islands, its extent is ten thousand acres, and from no other spot does the sheet of water look more imposing than from the wooded heights and sandy shores of Brownsea. At low tide several channels can be traced by the darker hue of the water as it winds between the oozy mud-banks, but at high tide the whole surface is flooded, and there lies the great salt lake with her green islands set like emerald gems on a silver targe. Eastwards from Bournemouth Pier the cliffs are bold and lofty, and are broken only by small chines or narrow gullies. On the summit of the cliff a delightful drive has been constructed, while an undercliff drive, extending for a mile and a half between Bournemouth Pier and Boscombe Pier, was formally opened with great festivities on 3rd June, 1914. Boscombe Chine, the only large opening on the eastern side of Bournemouth, must have been formerly rich in minerals, and Camden, who calls it "Bascombe", tells us that it had a "copperas house". On the eastern side of the Chine a spring has been enclosed, the water being similar to the natural mineral water of Harrogate. The whole of the Chine has been laid out as a pleasure garden, although care has been taken to preserve much of its natural wildness. Unlike most of the other chines along this stretch of shore, the landward termination of Boscombe Chine is very abrupt, which is the more remarkable as the little stream by which it is watered occupies only a very slight depression beyond the Christchurch road on its way down to the sea from Littledown Heath. Boscombe House stood formerly in the midst of a fine wood of Scotch pines. The estate is now being rapidly developed for residential purposes. The house was the home for many years of descendants of the poet Shelley, who erected a monument in Christchurch Priory to the memory of their illustrious ancestor. The house lies between the Christchurch road and the sea, and was almost entirely rebuilt by Sir Percy Shelley about the middle of the nineteenth century. The rapid growth of Boscombe may be gauged by the fact that between thirty and forty years ago Boscombe House and a few primitive cottages were the only buildings between Bournemouth and Pokesdown. Like her parent of Bournemouth, whom she closely resembles, Boscombe is built on what was once a stretch of sandy heaths and pine-woods. A pier was opened here in 1889 by the Duke of Argyll. It was built entirely by
