Horneman states 1500 warriors, or _men bearing arms_, as the _data_ for estimating the population of the country: he must mean to say, _men capable of bearing arms_, or there are no _data_, and he means nothing. Calculate a population on the widest latitude from such data, and apply it to a well-cultivated district of 127,360 square acres, and there will not be more than one cultivator to at least 50 cultivated acres: for the women, our journalist has otherwise engaged. They (as he tells us,) are employed in manufacture, and chiefly in that of wicker-work and baskets, which they work with great neatness and ingenuity. These statements carry self-contradiction. These lands cannot be so extensive, or cannot be so cultivated. Thus from Mr. Horneman’s own account, we may infer, that the rich spot of country termed the Oasis of Siwah, must be of much less extent indeed, than that which he directly states. Observing particular expressions in the Journal relative to this subject, the cause of error may possibly appear. The traveller says, “the territory of Siwah is of considerable extent; its principal and most fertile district is a well watered valley of about fifty miles in circuit, _hemmed in by steep and barren rocks_.” Now, referring to other descriptions of the fertile district or Oasis of Siwah, it is to be remarked, that such rich and productive spot of country is no where described, as _immediately_ bounded and hemmed in by steep rocks and mountains. Diodorus, lib. xvii. speaking of the Oasis of Ammon, says, it was surrounded on all sides by barren and arid sands: so too, Mr. Brown mentions the fertile soil or Oasis, of from four miles and an half in breadth, to six in length, as bordered and encompassed by “_desert land_;” intimating _plain_. In truth, it is such desert border of plain, which further on is bounded by rocky mountains. Mr. Horneman appears to have made no excursions from the town of Siwah, further than _of a mile and a half_ to the ruins, and _of one mile_ to the catacombs of _El-Mota_. From all these considerations, it may be surmised, that our traveller looking from Siwah, or its adjacencies, to the hills or rocks surrounding him at a distance, comprized in his estimate of rich country, the whole intermediate plain, not having directed due inquiry or consideration in the ascertaining of, to what extent within the area of that plain, the rich and cultivated soil might reach? Or, perhaps, he _did_ make enquiries; but of some patriotic Siwahan, who thought proper to exaggerate the richness and extent of his petty commonwealth, and confirm his hyperbole, by pointing to the lofty boundary in view: or, perhaps, from not sufficiently understanding the dialect of Siwah, (as the traveller himself allows,) he may have confounded the ideas of _country occupied_, and of _territory claimed_.
