It must have been a fit of temporary obliviousness, brought about by the unaccustomed heat of the sun.
Or possibly the kif….
It affects people differently.
I must limit myself to three pipes, in future.
Chapter XVII
ROMAN OLIVE-CULTURE
Now, on the former occasion, instead of descending into the bordj from the railway line, I rode with the Tripolitan once more out of the rock-portal into the plain, that glowed with the fugitive fires of sunset. It is a treeless waste, bereft of every sign of cultivation.
And yet, if you look on your left hand as you issue from the gorge, you will perceive, at the very narrowest point, some fragments of ancient masonry adhering to the cliff; they are all that remains of a Roman dam which blocked up the valley, regulated the supply of water flowing from above, and purified it from stones and sand. The inference is clear: the plain must have been cultivated in those days. Likely enough, it was covered, like many other parts of "Africa," with olives, that drew their life from this judiciously managed water-supply.
The Oued Seldja to-day fulfils no such useful function. Once the rock-portal is passed, it unlearns all its sprightly grace and trickles disconsolately through the sands, expiring, at last, in the dreary Chott el Rharsa.
Monsieur Bordereau thinks that the ancient "forest of Africa" was composed chiefly of olive plantations, and proofs of the former abundance of these trees can be found in certain local names, such as Jebel Zitouna—the Mount of Olives—clinging to localities where not a tree is now visible; there are also sporadic oleasters growing near many Roman ruins. Strong evidence; and still stronger is this: that Roman oil-presses have actually been found, buried in the desert sand. Up to a short time ago the Arabs deliberately destroyed the olives, to avoid paying the tax on them; the French have changed all this, and though I am not aware that they go so far as did the Romans, who encouraged tree-planting by exemption from imposts, yet they have inaugurated a severe regime; one reads with satisfaction of exemplary penalties inflicted for illicit timber-cutting.
