Between it and the Arghandab, at least six cuts occur: these are met with generally in threes, and are at different elevations; the inner one being close at the foot of the hills; great labour must have been required to make them. Numerous villages, some with flat roofed houses occur.
Arundo, Salsola, Plantago, P. coronopoid, Cnicus, Juncus, Veronica exallata, Santalacea, Mentha, Lactucoides, Chenopod. 2-3, Panicum, Samolus, Ceratophyllum; Salix occurs near the river; apricots, apples, pomegranates, damsons or plums, bullaces, pears, mulberries and raspberries in the gardens.
The shingle found about all the hills in Khorassan, can scarcely be derived from any source but disintegration, it slopes too gradually and uniformly for upheavement. If my idea is correct, the mountains will at some period be buried in their own debris, of course inspection of the shingle will at once point out whether this is true or not, more especially in all those places where the rocks are of uniform structure. There is a curious desert to the south and southwest of Candahar, elevated a good deal above the valley, quite bare, and stretching a long way to the westward: it is seen for forty miles along the Girishk road.
Curious reflection.—Observed in ghee used as lamp-oil, a bubble ascending from the surface of the water on which it floated, met by another descending; the deception of this is perfect. That it is due to reflection, is apparent from the variation of the length of the descent, according to the angle under which it is viewed. When viewed from beneath at a very oblique angle, the descent is complete, but if viewed parallel to the surface, no appearance of the sort occurs. The reflection is due to the surface of the ghee which appears to be more dense than the rest, probably more oily; this mathematical reflection may suggest others of a moral nature, touching our liability to mistaken views of things, from observing only one side.
Old Candahar is about three miles to west of the new town; it is immediately under a steep limestone range, running about southwest, and not exceeding 500 feet in height. It bears marks of having been fortified, and at either extremity remains of forts are still visible. The fort of forty steps is at the north end of the range. The town is in complete ruins; indeed none of the edifices are visible except those that occupy the mound of stones, (with which they are partly built) probably the site of the citadel. On three sides, the town is fenced by two respectable ditches, the outer one about 50 yards wide; both are now, especially the outer, beds of marshes; they were supplied by cuts from the Arghandab river. Wells exist however. There is one white mosque in good preservation. The works were strong, and much better than the very indifferent ones of new Candahar; and the walls of the town were prolonged up the face of the hills.
About Candahar, conical houses occur, probably for granaries. A curious mosque cut out of the rock in situ, is seen on the Girishk road, with a flight of steps leading to it, cut in like manner out of the rock. There is also in the same quarter the fort of Chuhulzeenat, or forty steps; a work not of very considerable extent; and as in other Asiatic countries I have visited, troughs are cut in rocks for separating grain from the husk. But there is no work to be seen indicating vast labour or any genius.
Some remains of good pottery may be picked up; and the earth of which the works, etc. were made, is filled with remains of coarse pottery.
27th.—Moved four miles to Shorundab, the country is very barren: not much Joussa: the water is brackish at our present encampment, which is within sight of Babawallee.
28th.—Proceeded to Kileeyazim, ten and a quarter miles, marched at 2 P.M. and reached the place at 6 P.M., the camels arriving one hour afterwards: the ground is generally good, throughout stony, difficult in places and undulated, particularly in two situations occasioned from cuts. There is a square fort, situated at the halting place with a tower at each corner, and on north face two; as well as towers at the gate: but without windows. Joussa is abundant, as also grass along the cuts. Salsola rotundifolia, a Chenopodia, and a curious prickly, leafless Composita and Joussa occur, the latter most common, Artemisiæ sp. Also rock pigeons and the raven. Halted one mile to the east of the fort.
29th.—Proceeded to the Turnuk, near Khet-i-Ahkoond, distance fifteen and a half miles. The country continues the same, no cultivation to be seen before reaching the Turnuk. The road tolerable, over gravelly or shingly ground: it was at first level, until we reached a mountain gorge, when it became undulated. Passed the dry beds of two streams, the second the larger: its banks were clothed with Vitex instead of Tamarisk. At the entrance of gorge a fort similar to that of yesterday was passed. Scarcely any change in vegetation. Artemisiæ one or two, Centaurea spinosa, Salsola cordifolia and aphylla? are the most common plants, Euonymus and Malpighiacea? Polygonoides, occurred along the nullah, a pretty species of the plant, Antheris globosis petaloideo-terminalis, in profusion in some places, literally colouring the ground: close to it another very distinct species, foliis connatis, floribus albis, a Rubiaceous crystalline looking plant, another novelty; all the plants about the hills at Candahar continue: Dianthoid, Statice, Pæderia villosa. Cultivation along the Turnuk, melons in small trenches, the crops are now cut, Jhow or gaz along the bank: but there is not much water. The hills around are apparently of limestone, very picturesque, and presenting very fine cliffs. The valley of the Turnuk is here very narrow, and the country very arid looking, completely burnt up. Joussa rather scarce, doob grass occurs along the river, the water of which is discoloured.
