In the warehouses of Timbuctoo, are accumulated the manufactures of India and of Europe; and from thence the immense population that dwells upon the banks of the Niger is supplied. There is no doubt that we could furnish the articles they want, upon much lower terms than they can obtain them at present; and, in return, we should furnish the best market they could have for their gold, ivory, gums, and other rich products, and raw materials.

Now, it certainly appears to me, and I think it must appear to every man who takes the trouble of investigating the subject, that, provided Government would give proper support to the enterprise, this important communication might easily be established. For this purpose, nothing more is necessary than to take a fortified station upon the African coast, somewhere about the 29th degree of north latitude, near the confines of the Marocco dominions, to serve as a safe magazine or emporium for merchandize. From this station it would be easy to maintain a direct correspondence with the opulent merchants of Timbuctoo; regular caravans might be established to depart at fixed periods; the protection of the Arabs can at all times be purchased at stipulated prices, which may be considered as premiums of insurance, or as a tax for convoy, and thus in a little time these caravans might carry out merchandize, to and from Timbuctoo, with as much regularity and safety, and with less expense, than our fleets convey our goods to and from the West Indies.

The expense of such a fortified station as is here proposed, would be very moderate, in comparison with the advantages it would produce; and it would be easy to draw out a plan for it; but I do not think it would be proper to go into a detail here,--"non est hic locus."

It has been well observed, that commerce is the key of Africa; and I shall only add, that if the plan I have suggested were carried into execution, these interesting regions of Africa, that have heretofore baffled the attempts of curiosity and enterprise, and remained for so many ages a "sealed book" to the inhabitants of Europe, would soon be explored and laid open. This is an object that cannot be indifferent to a prince, who has so evidently evinced a desire to patronise science, and who is undoubtedly desirous to encourage, to facilitate, and to increase, still further the vast geographical discoveries which have added such lustre to the reign of his august father.

To return to Mr. Jackson's book. This work contains, besides the information that more directly concerns the statesman and the merchant, much interesting matter for the natural and moral philosopher, as well as for the general reader. The author makes no pretension to fine writing; his style is plain, unaffected, and perspicuous, and there is as much new, authentic, and important matter in the book, as in the hands of the French writers of African travels, (Golberry, Vaillant, and Savary, for instance,) would have been spread over three times the space. Upon the whole, it is the most valuable work of the kind that has appeared for many years. I hope the author will reap the reward which his labours have so well deserved.

Sir,

The venomous spider (Tendaraman). This beautiful reptile is somewhat similar to a hornet in size and colour, but of a rounder form; its legs are about an inch long, black, and very strong; it has two bright yellow lines, latitudinally crossing its back; it forms its web octagonally between bushes, the diameter being two or three yards; it places itself in the centre of its web, which is so fine, as to be almost invisible, and attaches to whatever may pass between those bushes. It is said to make always towards the head, before it inflicts its deadly wound. In the cork forests, the sportsman, eager in his pursuit of game, frequently carries away on his garments the tenderaman, whose bite is so poisonous, that the patient survives but a few hours.

Charmers of serpents (Aisawie).--These Aisawie have a considerable sanctuary at Fas. They go to Suse in large bodies about the month of July to collect serpents, which they pretend to render harmless by a certain form of words, incantation, or invocation to Seedy ben Aisah, their tutelary saint. They have an annual feast, at which time they dance and shake their heads quickly, during a certain period, till they become giddy, when they run about the towns frantic, attacking any person that may have a black or dark dress on; they bite, scratch, and devour any thing that comes in their way. They will attack an unjumma, or portable fire, and tear the lighted charcoal to pieces with their hands and mouths. I have seen them take the serpents, which they carry about, and devour them alive, the blood streaming down their clothes. The incredible accounts of their feats would fill a volume; the following observations may suffice to give the reader an idea of these extraordinary fanatics. The buska and the [238]el effah are enticed out of their holes by them; they handle them with impunity, though their bite is ascertained to be mortal; they put them into a cane basket, and throw it over their shoulders: these serpents they carry about the country, and exhibit them to the people. I have seen them play with them, and suffer them to twist round their bodies in all directions, without receiving any injury from them. I have often enquired how they managed to do this, but never could get any direct or satisfactory answer; they assure you, however, that faith in their saint, and the powerful influence of the name of the divinity, (Isim Allah,) enables them to work these miracles: they maintain themselves in a miserable way, by donations from the spectators before whom they exhibit. This art of fascinating serpents was known by the ancient Africans, as appears from the Marii and Psilii, who were Africans, and showed proofs of it at Rome.
