should continually be on board, sufficiently acquainted with the river and with the indications of the weather to warn vessels, by sigual or otherwise, of approaching danger.

In addition to the light, I would place a buoy off the north-west end of the spit, and another off the south end, which I think is all that would be necessary in any ordinary weather; but in standing in from sea, I am decidedly of opinion that a stranger should not attempt to run in, unless certain of getting within the bar if there are indications of bad weather; but rather, he should seek anchorage among the islands, or else put to sea for the night; the former would be preferable in heavy weather, for, unless a good sailer, a vessel would not fetch up again, in the north-east monsoon. The tides are so strong, and at times so uncertain in direction, that the best acquainted persons cannot hope to keep a correct reckoning at night; and it would prove very rough riding, should a ship attempt to anchor between Gutzlaff and the North Sands in a gale.

I think it quite useless attempting to erect a beacon on the Sand with the means that would be available here, as the tide runs with great velocity, and I am not aware that any part of the patch has less than nine feet water on it. The flood often comes in with a heavy bore or roller, when a southerly wind is blowing; and I do not think that a sufficient foundation could be formed, to justify the expectation of a beacon standing the combined action of the wind and tide.

No doubt a beacon might be placed on the North Sand itself, where it dries in many ways; for instance, by sinking a foundation in iron tanks; but it would be at a greater distance from the channel; it would cost more to keep a light on it, and altogether it would be less useful than a floating light.-Hongkong Register.

A YOUNG SALT.

DESCRIPTION of the Monumental Tower in Honour of SIR JOHN BARROW, BART., on the HOAD HILL, ULVERstone.

[Our last volume contains an account of the ceremony which took place on laying the first stone of the edifice which is now completed and known as the Barrow Tower. The Architect, Mr. A. Trimen of the Adelphi, London, has favored us with the following description to accompany the view of it in our present number.]

The plan of the tower is circular, with a spreading base, the general form being similar to the Eddystone; the lantern however in this case is of the same material as the general structure, and forms a consistent architectural feature.

The structure is based on the solid limestone rock, of which the Hoad Hill is composed, and which was found immediately under the turf at the summit.

The ring immediately above the surface is 150 feet in circuit, being in wrought stone, and forming a set off or base, two feet in width, from

[graphic][merged small][merged small][merged small][merged small]

which the surrounding panorama, one of the most beautiful in England, may be contemplated in all directions.

The thickness of the wall at the surface is twelve feet six inches, intersected with a dry chamber five feet at the base, The wall diminishes in thickness from twelve feet six inches, to two feet at the cornice, which is formed of massive wrought limestone.

The whole of the lantern and dome, is formed of the same material, being wrought within and without.

The steps, the door, and window jambs, the several rings of set offs, are all in the durable wrought limestone of the neighbourhood. The general walling is in the same stone, and hammered to a sufficiently correct form. The lime of the mortar is from the same material, and set so hard, that, as the whole is compactly built (every stone being completely bedded in the mortar, and every joint completely flushed or filled,) in a short time the walls will form one thickness, of a most strong and lasting character.

Probably no stone and mortar with which we are acquainted, is better calculated to resist all influences of weather, than that of Furness, and this monument bids fair to stand as lasting to record, as any in the island, an event of the age.

The interior is approached from due south by a wide flight of steps, and over the entrance door is cut in bold relief, the words:

IN HONOUR OF SIR JOHN BARROW, BART.

ERECTED A.D. 1850.

The saloon or principal floor is elevated about seven feet from the summit of the hill, thus furnishing a basement beneath.

This apartment is eighteen feet nine inches in diameter, having deeply recessed windows to the cardinal points, the view from each of which can be scarcely equalled, either for sublimity or variety of beauty. A stove and range are formed in the recess of the west window, and a circular pedestal, with circular shelf table will mark the centre.

The several floors and lantern are gained by a solid flight of stone stairs, protected by an ornamental iron balustrade, cast on the spot from the valuable ore procured from the base of Hoad. The pattern is of the fifteenth century, and each exhibiting the initials J. B.

Iron girders form the skeletons of the several floors (the whole being fireproof,) and the visitor while winding the surface of the interior of the cone, is cheered by an occasional peep from the several windows with which the sides are pierced, and reminded of the reward of the beautiful prospect that awaits him at the summit.

The interior of the lantern is nine feet four inches in diameter, and perforated with eight circular openings, the same number of pilasters support the entablature and dome; around the interior are graven the words Soli Deo Gloria.

A flag-staff of due proportions will be securely fixed to the base and cornice of the lantern, from which the flag of the nation, (a line-of-battle ship's Union Jack, which, together with the flag-staff, was presented by the Lords of the Admiralty, as a mark of their respect to the memory of Sir John Barrow)-wafted by his native mountain breezes, will an

nounce to generations yet unborn, that the day of the birth of true greatness excites a nation's joy, while that of his death is felt with a nation's regret; and the tower beneath will stand as a monument of the events of a life passed in the service of his country, and extending over every hemisphere, honoured and appreciated by all classes of his fellows.

TABASCO AND ITS RESOURCES.-From a paper translated from the the Spanish, by Lieut. Mooney, R.N.

THE waters which descend from the mountains lose their force at the commencement of a gently inclined, slightly sloping plain, and deposit the soil which they have dislodged in their passage. By this constant occurrence nature has in the lapse of ages, gained from the ocean all that region in which is situated the state of Tabasco, a plain between the margin of the ocean and the torrents of the mountains. Many rivers and rivulets intersect it in various directions, which form a delta, affording the greatest facilities for the furtherance of agriculture, such is the fertility of the soil and the cheapness and commodiousness of transport, for in all the newly formed lands, the first strata are composed of vegetable earths or alluvium deposited by the waters which cover the greater part of the surface, and renovate its productive faculties.

But these stimulants so propitious to the development of plants, are unfortunately deleterious to the human race; inasmuch as the excess of heat and moisture engender, remittant fevers, diarrhoeas, and diseases more or less dangerous: to all of which the inhabitants of this part of the republic are obnoxious.

These endemic diseases will always be an obstacle to the progress of agriculture in Tabasco, being opposed to the increase of population, either by producing more mortality than without this cause would occur, or by discouraging emigration, or finally by causing the loss of much time and labour to those suffering from their effects. Notwithstanding, I think that the insalubrity of the climate of Tabasco is exaggerated, and that it is not greater than the ordinary proportion awarded to human nature, which I have arrived at by the experience of many years, and the comparison of data of different countries, the facility of acquiring such information in Tabasco being taken into consideration.

The abundance of the first necessaries of life, and the fertility of the cultivated soil ought to give us hopes of a more rapid increase of population, if means were adopted to give exit to the stagnant waters, to eradicate the jungles near the towns, and drain the marshes; in fine to diminish the causes of these diseases.

In the rainy season the rivers overflow, and the face of the country seems as a large lake, studded with islets, on which are situated the villages or estates. At times so great is the rise of water, that many of these islets disappear, as happened last year in the district of Choutalpa, its inhabitants were obliged to fly to higher situations, to save their lives,
