Section I. From The Lands End To The Bristol Channel

Near the shore, between Mount's Bay and the Land's End, there are several dange rous rocks. The UTTNIHiSSTOJ-TE.— The first is the Rundlestone, a small roct about 4 yards long and 2 broad, the base of which is dry at low water, and covered before half flood. From this rock the lighthouse on the Longships, hereafter noticed, bears N. 19° W., distant nearly 4 miles; the flagstaff on Point Tol-Pedan-Penwith N. 7° E. three quarters of a. mile ; with the point distant a quarter of a mile. The ground without the Rundlestone is clear, but there are rocks and foul ground to the eastward and northward of it ; therefore a passage within it canuot be recommended to strangers. A Beacon on it was completed in June, 1843, after two summers' arduous labour; anil, like tbat on the Wolf Rock, consisted of an artificial cone, bearing a staff with a ball on its summit, at 19 feet above high water spring tides.

The tides rise 19 feet, and at low water the rock is uncovered 7 feet. It was announced on Nov. 26, 1852, that the standing beacon upon this rock, which cost such infinite pains in the construction, was carried away during a severe storm on November 23rd previous. It was reinstated in 1856. Leaw-Mean. — About 1 cable's length N.E. by N. from the Rundlestone, is a rock, called the Leaw-mean, which appears at half ebb. There is a passage between these rocks aud the raaiu, in which there are 12 fathoms of water; but it is seldom used. To sail clear without them, keep the windows of St. Levan's church open above the land : the same church shut in with the land is the mark to sail within them, and will lead clear through. About half a mile N.N.W. from the Rundlestone lies the extremity of a bed of sunken rocks, which extend thence toward the Rundlestone and Leaw-mean, having only 4 feet on them at low water.

This bed of rocks is not more than a cable's length over each way. The WOLF ROCK, a rock which is barely covered at high water in neap tides, bears from the Land's End, or the westernmost point of land, S.W. f W., 8 miles distant. Betweeu the Rundlestone and this rock there are from 20 to 36 fathoms of water. It is steep on all sides, and has vithin a cable's length of it from 30 to 40 fathoms all round. The sea makes such a roaring on it, that the noise may, in moderate weather, be heard a great way eff. This rock is 56 yards long and 38 yards broad, at low water bold all round, and always shows itself, except at high water spring tides, and a very smooth sea. From this rock the lighthouse upon the Longships appears a little within tho rocks called the Brissons (about one-third of the distance to Cape Cornwall), bearing N. 44° E., distant 7£ miles: and the Wolf bears from Tol-Pedan-Penwith S. 67° W., or W.S.W., distant nearly 7£ miles.

The Beacon. — In four summers preceding July, 1840, under the direction of the Corporation of Trinity House, and impeded by much danger and difficulty, a beacon was erected upon the rock, which was completed at the date above mentioned. This r. i. *m r. i • MOUNT'S BAY TO THE LAND'S END. beacon consisted of an artificial cone, of 18 feet at the base, bearing a mast having a large ball or globe upon its summit, at an elevation of 36 feet above the level of the sea, at high water; and mariners are to observe that spring tides rise at this station 19 feet, and that at low water of those tides the rock is uncovered to the height of 15 feet. It being of great importance that the beacon should not sustain injury, mariners have been cautioned and enjoined not to approachit on any consideration, lest their own safety as well as the security of the structure should be thereby unnecessarily endangered.

Contrary to all expectation, the pole and globe of the beacon were carried away during the memorable storms of November, 1840. This has occurred more than once, the last time in March, 1848, and is an evidence of the wonderful force of the waves. The beacon is reinstated with all practicable despatch. BEACONS near TOL-PEDAN-PENWITH— The Corporation of Trinity House* in the hope of preventing a recurrence of the melancholy and serious losses which have frequently been occasioned by vessels striking on the Rundlestone, when navigating lound the Land's End, have lately caused two beacons, in a line with that stone, to be erected at Porthwarrow, near Point Tol-Pedan-Penwith, whereby masters of vessels may navigate with greater security both to the northward and southward of that dangerous rock.

The southernmost or outer beacon is of a conical form, and painted red. The northernmost or inner beacon has a large and extended base, and is coloured black, excepting a small part of the pillar, which is painted while immediately above the base. To sail to the southward of, or without the Rundlestone ; Masters of vessels must take especial care not to bring the beacons in one, un , til the base of the northernmost or black and white beacon is wholly seen above the land, or the Longships lighthouse bearing N. by W. ; when the line of the beacons may be crossed, and vessels pass to the southward of the stone in safety. To sail to the northward or inside of the Rundlestone ; The same degree of caution must be used not to briug the beacons in one, until the white part of the inner or northernmost beacon is entirely hidden by the land, aid the Longships lighthouse just open of the land ; when ihe line of the beacons may be crossed, and vessels pass to the northward cf the stone.

To sail through the inner channel, which is considered the best, as the tide sets more regularly therein, and begins to run to the eastward (which it does for three hours only) one hour before high water on shore, shut in the Longships lighthouse with the land or keep Teller Due on with Castle Treen Point. None of tbe rocks within the Rundlestone have more than 9 feet of water on them at low water, and some have much less ; and in stormy weather, at low water, the sea may be seen breaking on them most tremendously. The tide flows at the Rundlestone at 4b 45' at the full and change days of the moon and that rock can be seen at half ebb ; till which time the tide sets to the" eastward. N.B. The beacons, when in a line with the Rundlestone, bear therefrom N. 17° E. LONGSEIPS.- About 3 miles N.N.W. £ W. from Tol-Pedan-Penwith, or the S.E. point of the Land's End, and 1 mile W.N.W. from the westernmost point, lie the high rocks called the Longships ; which extend in a North and South direction, about half a mile.

Upon the largest of these rocks stands the lighthouse, mih fixed light, which was erected in the year 1795, and the lantern of which is lighted with Argand lamps and reflectors, so as to be clearly seen from Point Tol-Pedan- Penwith to Cape Cornwall. From the light, Point Tol- Pedan-Penwith bears S.S.E. £ E., distant 3J miles; Cape Cornwall N.E. -J E. 4 miles ; the Brissons N.E. £ N. 3\ miles ; the Rundlestone S.S.E. southerly, nearly SCILLY ISLES. 3 4 miles; the Wolf Rock S.W. southerly, 7f miles; and the lighthouse of St. Agnes, Scilly, West, northerly, 25 miles. LAND'S UND.— The cape called the Land's End is so high as to be seen in clear weather 8 or 9 leagues off. When first seen at a distance it appears in two round hummocks, on the highest of which is a spire steeple : upon nearer approach, on the outermost point another spire will appear.

By these objects the Land's End may be readily known ; but at all times the Longships lighthouse will indicate its situation. Cape Cornwall lies N.N.E. f E, about 3J miles from the Land's End. Iu the bay between, called Whitesand Bay, which lies about a mile to the northward of the latter, vessels may ride in from 19 to 25 fathoms, well sheltered from E.N.E. aud easterly to S.S.E. winds; but the danger arising from westerly winds makes it little frequented. The South side of the bay is formed by Peddenmeundue Point, from which the ground is foul and rocky to half a mile N.W. TIDE. — On running between Scilly and the Lizard, attention to the setting of the tide is of great importance, especially with southerly and S.W. winds. Between the periods of high and the following low water, by the shore, the stream runs S.E., South, and S.W., or from the Wolf Rock ; whilst from low water to the succeeding high water it sets N.W., North, and N.E., or toward that rock.

This peculiarity extends to a supposed radius of 4 leagues from the rock, in an easterly, southerly, and westerly direction ; whence, as you approach either Scilly or the Lizard, the tide partakes of the influence of the land. — Captain White. TKE SCX&XrY XSXiAZvDS. — The islands of Scilly consist of a great many small isles, islets, and rocks above water, surrounded by innumerable rocks and ledges, some of which appear at half tide, others at low water, and the greater part not at all. Many have 6, 5, and 4 feet on them at low water spring tides. The channels or pas sages into the harbours are called Sounds. They are dangerous, but well known to the fishermen of the islands, who act as pilots. With an easterly wind, a number of pilot boats are on ihe lookout for vessels from the westward.

The principal islands are St. Mary's, St. Martin's, St. Agnes, with Hugh, Tresco, Bryer, and Samson. Of these the central and principal island is St. Mary's ; the southern, St. Agnes; the N.E., St. Martin's; the N.W., Tresco and Bryer. ST. MARY'S is only 2 miles in breadth. This island is composed chiefly of elevated rocky hills, abounding in mineral ore, but has some fertile spots inclosed by stone fences. Hugh (properly Heugh) Town, the only town of Scilly, is on the western side of this island, and is defended by Star Castle, which commands the fort. ST. AGNES, which is also called Lighthouse Island, lies nearly l£ miles to the S.W. of St. Mary's. It is the southernmost of the Scilly Islands, exclusive of a group of large rocks, which cannot properly be called islands. To the westward of these is that called the Gilstone, where Sir Cloudesley Shovel, in the Association man-of-war, was lost in 1707.

Shipwrecks have been too frequent about these islands. The Lighthouse is the principal ornament and great support of the island. It stands on the most elevated ground, built with stone from the foundation to the lantern. It was built in 1680, and is 53 feet high. It is a noble und commodious structure; and being plastered white, is a useful daymark to all ships coming from the southward. The light revolves and is visible every minute, and in clear weather it may be seen at more than 5 leagues off ; the lantern being 138 feet above high water mark. St. Agnes, &c. — Tke Lighthouse (A) bearing N.N.E. 3 leagues. ST. MARTIN'S HEAD is the first and highest land seen by those advancing from the N.E. It is the N.E. point of the islands, and has on it a red landmark of stone, in the form of a steeple, 40 feet in height.

It was formerly white, but is now painted red, to distinguish it from the lighthouse of St. Agnes. Between this island and the islets to SCILLY ISLES. 4 the S.E., there is a sound, through which small vessels may come in ; but few enter thai way, unless well acquainted with the marks and the settings of the tides. The S.W. DANGERS of Scilly are those called the Bishop and Clerks, composed of a high rock, called the Bishop ,■* and of several ledges to the South and East. The Bishop's Ridge, having a race upon it, lies nearly a mile to the South of the Bishop, with the lighthouse on St. Agnes bearing East, 4 miles distant. Tbe Poul Bank, a reef of 15 fathoms, lies 4 miles to the W. by S. from Gorregan (one of the southernmost islands), with St. Agnes' lighthouse E.N.E. f E., G\ miles dis tant.

Its mark is, the lighthouse on with the N.W. point of Meledgan, through the /.riddle of Gorregan. The great importance of the Scilly Islands arises from their advantageous situation, as looking equally into St. George's Channel, which divides Great Britain from Ireland, and into the English Channel, which separates England from France. From this reason many ships, when the wind is favourable, in coining in from the S.W., endeavour to make the islands, in order to steer their course with greater certainty. It is also some times convenient for vessels to take shelter among them rather than beat about at sea in bad weather, and a strong gale at East will be frequently the means of bringing in numerous vessels. Upon firing a gun, and making a waft, a boat immediately puts off from the nearest island with pilots.

In coming from the southward you will descry Scilly, in clear weather, at the distance of 6 and 7 leagues, and have 60 fathoms, with gray sand, broken shells ; you may also see the land from the southward, in 55 fathoms of water, stony ground with some shells ; but at 7 leagues distance to the northward, you will have sand and oaze mixed together. From the lighthouse of St. Agnes, the Lizard bears E.S.E., distant 14-"f leagues ; the Longships lighthouse E. \ S., distant 8 leagues ; and the Wolf Rock, E.S.E. \ E. 6J leagues. Tbe SOUNDS. — The principal sounds, or passages, formed by the Scilly Islands, are St. Mary's Sound, between St. Mary's and St. Agnes ; Crow Sound, between St. Mary's and the Eastern Isles ; Smith Sound, on the West of St. Agnes ; Broad Sound, or the S. W. and N. W. Channels ; there are, besides, on the N.W., the inlets named New Grimsby, Old Grimsby, Si.

Helen's Gap, Tean Sound, Q-c, all of which are environed by numerous dangers. ST. MARY'S SOUND and ROAD.— This sound, which extends to the N.W., between the islands of St. Mary and St. Agnes, is the safest channel, and the road is the best road in the islands. On advancing toward St. Mary's, the whole of St. Agnes must be kept open of Pe ninnis Point, 'he South point of St. Mary's. You will thus avoid the Gilstone, which lies at one-third of a mile E.S.E. from the point. The point is bold-to, and has at some distance above it an old mill without vanes. After passing Peninnis Head, a N.W. course, for about three-quarters of a mile, will iead outside the Woolsack Poiut, which has a battery upon it. Having passed the Woolpack, you steer nearly North, toward Samson, and will thus leave a conspicuous rock called the Stevel, on the starboard hand.

The last lies near Stevel Point, the westernmost point of St. Mary's, and is steep-to. The point may be known by a house upon it, with a chimney at each end. Having pasted Lite Stevel Rock, continue to the North until the landmark on St. Mar tin's Head comes open of St. Mary's Island, and bearing E.N.E. £ E.; then steer for the roads, having St. Martin's landmark on with the Crow Rock, E.N.E. J E. With the last mark you may anchor, on the best ground, in 7 fatiioms, when a rock, close to St. Mary's, called the Barrel of Butter, bears S.E. J S. But the general leading mark through St. Mary's Sound, leaving the dangers on each side, as already described, is that drawn on the chart; namely, the North end of Min carlo on with Great Minalto, bearing N.N.W. j W. This mark is to be kept on until you open St. Martin's daymark as above. * A lighthouse is now in course of construction on the Bishop, under the direction of Mr. Walker, tho engineer to the Trinity Corporation.

A structure consisting of nine iron shaft*, above 100 feet high, was completed to the base of the lantern ; but during a severe storm it disappeared. The project, however, is not abandoned. THE SOUNDS 5 As the passage is narrow, in working through St. Mary's Sound, stand no nearer to St. Mary's than with Mincarlo its breadth open to the East of Minalto, nor nearer to St. Agues than with Mincarlo its breadth to the West of Minalto. The Roads. — Should St. Mary's Roads be crowded with vessels, you may anchor inside the following marks, allowing* room to veer; they will also answer for working iu the roads. Approach no nearer to St. Mary's than with St. Martin's landmark open of St. Mary's Island, bearing E.N.E. ; nor nearer to Tresco and the rocks about it than with the South end of Samson Island to the South of the Nut Rock, bearing W. by N. ; nor nearer to Samson Island and its rocks than with Skirt Isle (the eastern part of Tresco), on with the Nut Rock, bearing E.N.E. ; nor nearer to Broad Sound than with Woolpack Point shut in with the Stevel Rock, bearing S.S.E. St. MARY'S POOL is the cove off the town and pier.

The ground is not good for holding, but it is out of the tide, and small vessels lie at anchor off the pier, in about 15 feet at low water, sheltered from all but westerly winds, being nearly landlocked, and where not so, sheltered with rocks, excepting just at high water. The leading mark in is, the interval between Bryer and Tresco open of Crow Point (the South point of Tresco) bearing N. | W. This will lead between the Crow Rocks and the Beaton Ledge, in 3 fathoms. You may anchor with the same marks on, and Star castle open to the West of Rat Isle, in 15 feet at low v*aler ; but the space is much confined, as shown by Chart. CROW SOUND lies between St. Mary's, on the West, and the cluster of small isles called the Eastern Isleson the East. It should not be attempted by a stranger, unless in case of emergency, and at tide time only.

On entering the Sound you may approach St. Mary's to within an eighth, and should not recede from it more than one-third of a mile. Bar Point, the North point of St. Mary's, which is a low, sandy point, kept open of Insidgen Isle, is the leading mark. In passing the isle do not approach too near it. Vessels entering Crow Sound from the southward, will bring the Hedge Rock, between St. Martin's and Tresco, in a line with the eastern edge of Guther's Isle, and bearing N. by W. $ W., until Bar Point, the North end of St. Mary's, bears N.W. by W. Those from the eastward may enter by the South side of the Eastern Isles, with the northernmost point of Samson open of the southernmost point of Tresco, bearing N.W. by W.fW. This mark will lead in between the Biggal and Trinity Rocks, and thence just to the South of the Hats, &c, until you bring the South point of Samson Island W. -J- N. just to the South of the Nut Rock.

With the last mark you pass over Crow Bar, just to the South of the .Crow Rock.* So soon as you open the lighthouse on St. Agnes you may steer, by chart, for St. Mary's Road. The tides here set out to the S.E. at three-quarters flood, and at three-quarters ebb run back N.W. from the entrance of the Sound to the bar, where you will meet with the tide which sets into St. Mary's Road. SMITH SOUND.— This sound, which lies on the West side of St. Agnes, is narrow and dangerous, but has deep water. In coming from the southward, foi this place, you leave St. Agnes on the starboard side, and all the western cragged rocks and islands on the larboard, keeping the Castle Bryer (a high round rock to the westward of Bryer) on with the Great Smith, another rock to the N.W. of St. Agnes. Run in with this mark until near the Great Smith; then steer over toward Annet Island, and give it a berth on the larboard side ; afterward steer away for St. Mary's Road.

The tide sets out of this sound S.E. at 4 hours flood, and continues until 2 hours ebb, running nearly the same all through the western necks and rocks, as far as the Bishop and Clerks ; but to the northward of these you will meet with the harbour tide. BROAD SOUND. — This sound is dangerous to those who are unacquainted with the settiug of the tides. There are two passages leading into it, viz., those denominated the S.W. and N.W. Channels. To go through the S.W. Channel, which is the best of the two, you must sail in between the Bishop and the Crim, the two westernmost rocks • Tbe Crow Rock appears with three horizontal divisions. When the first is covered, there is a depth of 10 feet over the bar; when the second is covered, 16 feet; and when on the wash, 21 feet. SCILLY ISLES. of Scillv, and mostly above water, which bear from each other nearly N.N.E. and S.S.W. at the distance of l| miles.

To enter the N.W. Channel, bring St. Agnes' lighthouse about S.S.E., just to the West of a large rock, called the Great Smith, which stands near St. Agues, and continue this mark on until Bar Point, the North point of St. Mary's (low and sandy), bears E. $ N. The last mark will lead to St. Mary's Roads. Should you fall in with the Bishop and Clerks at low water, for about half an hour, and no more, you will find that the stream sets to the N.N.W. ; and if you stand to the northward you will find the tide shifting uutil you are a mile to the northward of all the islands, where it sets nearly East. At the Bishop and Clerks, at this half hour's flood, the stream will set easterly through St. Mary's Road, and as far as St. Martin's Head. Be cautious of going too far to the southward among these rocks ; for as the tide flows it parts, turning away to the southward ; and if you run too far to the northward, you will find it to do the same ; it is therefore necessary to take short tacks to get out.

Should the weather be so bad that you cannot carry sail, or if you find a contrary tide, then steer in for the Bishop or Criin, and as above directed. The NUN DEEPS are a ledge of rocks, which just show themselves at low water, and lie N.E. by E. about ]£ miles from the Crim. They are exceedingly dangerous to ships which fall in to the northward of the Crim, excepting to those who are well acquainted with the N.W. channel. NEW GRIMSBY. — Neic Grinzey, or, as commonly called, New Grimsby, is an ex cellent harbour, but small and narrow. You come in from the northward between the islands of Tresco and Bryer. There are two rocks, called the Kettle and Kettlebottom, just off the point of Tresco, which show themselves always above water; you sail in by them, keeping your starboard headland close on board.

You may anchor opposite the round peaked island called Hangman's Island, within the harbour, close over to Bryer, in 5 fathoms. Above Hangman Island, if desirable, you may go and lie aground, on a sandy beach, on the town of New Grimsby. It is difficult to get out of New Grimsby Harbour when the wind is fresh from the N.W., North, or N.E. ; but, with such winds, there is, at tide time, a passage over Tresco Flats into St. Mary's Roads, and thence to sea. OLD GRIMSBY, &c.-01d Grimsby, St. Helen's Gap, and Tean Sound are tolera bly good anchorages, pretty safe, but narrow and intricate, and not to be used without a pilot. Old Grimsby and St. Helen's Pool are both good places for small coasting vessels, or such as will lie aground ; you will find 12 to 8 feet in Old Grimsby at low water spring tides.

The entrance from the northward is deep, and when your ship is in, you are all landlocked, and may go to sea with any wind. The SEVEN STONES are a dangerous reef of rocks, which appear above water, some at half tide, and some at low water. They are a mile in extent from N.N.W. to S.S.E. ; the sea always breaks upon them, and, except in very bad weather, they may be seen from a considerable distance. LIGHTVESSEL.— The lights on board the Seven Stones lightvessel were exhibited, for the first time, on the evening of Wednesday, the 1st of September, 1841, and thence forth continued nightly from sunset to sunrise. Two bright fixed lights are shown, viz. — one on the mainmast, burning at an elevation of 38 feet from the surface of the water ; and one on the foremast, burning at an eleva tion of 20 feet above the same level.
