work in their houses at the production of these articles, and merchants go and purchase _à domicile_, there being now no shops. There are three market-places or bazaars, where prices are very low. [7] This is Dr. Barth's statement, which I have introduced from his own account. It will have been seen that Mr. Richardson (see vol. i. "Note on the Territorial Division of Aheer,") makes a much lower estimate. I may here remind the reader, that even when in his diary Mr. Richardson inserts two different and contradictory statements, I do not undertake to select one and suppress the other, except in the case of an obvious slip of the pen. Nor have I thought it necessary to burden the page by indications of slightly different assertions. A diary must necessarily abound with imperfect observations, which correct or complete one another; and perhaps the general impression left on the mind of the reader--who accompanies, as it were, the writer in receiving its various elements--is more like truth than it would be after the perusal of one absolute dogmatic statement.--ED. [8] As an illustration of the previous note, I will observe that this word is spelt in several different ways in the MS., and I do not know which is the correct one.--ED. The Sultan of Aghadez, the great Koku Abd-el-Kader, does not receive any direct contribution towards his revenues, from the people of Aghadez, but levies a kind of _octroi_ of ten mithkals on every camel-load of goods that enters the town, provisions being exempt. He has property of his own, however; receives presents at his installation; and can always raise a sum by making a razzia on any neighbouring freebooters.
