Rock moss (Parmelia perlata) is worth about 70l. a ton, and is one of the innumerable lichens common to the Canary Islands; it is used in the manufacture of cudbear for the dyers. There is also a spurious kind, with difficulty distinguished from the good.
Silk is chiefly produced at Palma. There is but little exported from Teneriffe. It might, however, be produced in immense quantities, the white and red mulberry tree being indigenous and luxuriant in the middle region of the island, and the climate so mild, that the insect could be hatched and reared under wooden sheds, without any difficulty. The great defect in the Teneriffe silk is the coarseness of the fibre, from want of dexterity in winding it off the cocoons, and in regulating the heat to which it ought to be subjected during that separation.
A considerable emigration used to take place annually from the islands, and particularly from Lancerota and Forteventura, to the Spanish Main, and to Cuba, where those islanders were much in request, as labourers and muleteers; and often prospered so well as to be enabled to return home enriched: but the practice has been prohibited since the declaration of independence of Spanish South America.
There is a considerable fishery carried on from the Canary Islands, on the coast of Barbary, for a species of bream, which is salted in bulk, and sold very cheap, and in great quantities. This trade is pursued in decked schooners, or lugger-rigged vessels, of from 60 to 70 tons burthen, which rum down before the trade wind to their station, where they remain until they procure a cargo, when they beat up to the island, take in a fresh cargo of Cadiz salt, and again return to their station. They have very little intercourse with the Arab tribes of that coast, but they sometimes bring back a few lion, tiger, and leopard skins, and ostrich feathers. I am happy to learn that our knowledge of the natural history of these islands is likely to be soon very much increased, by the indefatigable exertions of P.B. Webb, Esq., a gentleman well known to the scientific world, who is now engaged at Paris in publishing the result of his researches in different branches of natural history.
In the afternoon we took in some oxen and wine, and left Santa Cruz roads at seven in the evening. From Santa Cruz to Porto Praya, St. Jago, the course is S. 26 deg. W. 920 miles.
Monday, 20th.—Having crossed the tropic of Cancer last evening. Captain Owen granted the ship's company permission to perform the customary ceremony of shaving and ducking all those who had not previously passed the tropic. Whenever a ship is intended to enter the southern hemisphere, this marine exhibition is not performed until she reaches the equinoctial line. Although this ceremony has been frequently described, I do not think it right to pass it over altogether unnoticed; I will therefore make a few general observations by way of comment on the practice.
A sea voyage is at the best a monotonous life, and a long voyage is only to be wished for by the few whose health it is calculated to improve; therefore, any little variety, that produces even but a temporary excitement, is desirable; and in this point of view only, is the old custom of shaving and ducking (which, by the bye, is a barbarous one) at all excusable.
When it is permitted to be practised, it should only be under certain regulations, as the consequences have frequently been very serious, for want of some salutary restrictions; in some cases the harmony that has existed amongst the society on board has been destroyed; actions at law, and duels, fevers from exposure daring the day's amusement, have ensued: it is, therefore, imperatively necessary that the law should take cognizance of this custom, and enforce some rigorous rules for the government of all commanders of vessels, whenever circumstances should permit the indulgence of this indefensible practice. In the first place, the ship should be always put under snug sail; and that part of the vessel, in which the scene takes place, should be completely screened in, and no cruel or offensive practices permitted. The Captain should always have the power of protecting his officers and passengers from being compelled to submit to the demands of old Neptune, by paying a small fine for the exemption: say cabin passengers, five shillings, steerage passengers half-a-crown. The sum total of these fines should be divided among those sailors who had previously crossed the line; and, if any of the sailors on board should be found to throw water, rope yarns dipped in tar, or in any other way insult, or annoy, persons who do not take a part in their proceedings, they should be punished as they would for a similar breach of discipline at any other time. There is one example, which I feel at liberty to quote, and which was nearly the occasion of a court-martial on the senior lieutenant of one of H.M. ships that arrived in Simon's Bay during my residence at the Cape of Good Hope. The circumstance was as follows:—The purser of the ship had shut himself up in his cabin, determined to resist any forcible attempt to make him undergo the ceremony of shaving; but those who were engaged in it, were resolved that he should not be permitted to escape: they accordingly forced the door of his cabin, from which they got him out, dragged him on deck, and performed the ceremony, in spite of his efforts and remonstrances. The charge against the first lieutenant was, I understood, for encouraging the persons who committed this act of violence. This formed the grounds of an application for a court-martial, which was only prevented from taking place by the intercession of some officers of rank. It is satisfactory to be enabled to add, that this barbarous and unworthy custom is rapidly falling into disuse.
Wednesday, 22nd.—A moderate trade wind, and all sail set. At daylight saw the island of Sall, bearing E.S.E. 15 miles. At half-past 5 in the afternoon saw the island of St. Jago,[[7] ] when I went to the fore top-mast head, for exercise and amusement, while others went to see the land. At 11 brought the ship to the wind, and stood off the land at a convenient distance for going into Porto Praya on the following day.
At daylight, made all sail, and stood towards the anchorage, with a light breeze and very fine weather. At noon anchored off Porto Praya, in 12 fathoms water and sandy bottom. Extreme points of the bay from W. ¾ S. to E. ¾ S. Garrison flagstaff N.N.W. ½ W.
