From the account of the River Indus at its mouths, which is above given, it will appear that it would be accessible to steam-boats of a certain size and build; but I am thoroughly satisfied that no boat with a keel could ever navigate this river with any hopes of safety. The flat-bottomed boats are constantly grounding, but they sustain no injury; while boats differently constructed would be at once upset by the violence of the stream, and destroyed. It is not to be doubted, however, that steam-vessels could be adapted to this navigation as well as the existing boats on the river; and had not coal been found both at the head and mouth of the Indus, fuel could be supplied from the great abundance of wood which the banks of this river every where furnish. The Americans use wood for this purpose; and the supply of brushwood on the Lower Indus is abundant.
Military remarks on the Indus.
I make allusion to the navigation of this river by steam, because I am aware it is an object of interest; but, in conducting any expedition against Sinde, I feel satisfied, from what I have seen, that there would be little advantage, in a military point of view, derived from the river Indus below Tatta. It would be impracticable to march a force through the Delta, from the number of rivers; and it would be equally impossible to embark it in flat-bottomed boats, for there are not 100 of them below Hydrabad; few are of burthen, and the very largest would not contain a company of infantry. The vulnerable point of Sinde is Curachee, and a landing might be effected on either side of the town without difficulty. The Creek of Gisry, to the south-east, has been pointed out[22] as a favourable place, and I can add my concurrence in the opinion; but a force would easily effect its disembarkation anywhere in that neighbourhood. For a land expedition, the route from Cutch to Ballyaree, by the Thurr, seems to me the most feasible. While I represent the mouths of the Indus as unfavourable for conducting an attack from India on Sinde, I do not wish to be understood as hazarding at this time any opinion on like obstacles presenting themselves in an attack from its banks on India.
Supplies of the Delta.
With regard to the supplies which an army is to expect in the lower parts of Sinde, my report will be more favourable. Grain, that is, rice and bajree, will be found in great abundance. Horned cattle and sheep are numerous. The pasturage is not good, but near the sea abundant. Almost all the villages are mere hamlets; for Darajee, Lahory, and Shahbunder, which figure on the map as places of importance, have none of them a population of 2000 souls. The two first, indeed, have not that between them; and there are not ten other places that have a hundred souls below Tatta. Camels would be found in great abundance, as also horses: these are of a small and diminutive breed, but the camels are very superior. From the number of buffaloes, milk and ghee are to be had in great abundance, and all the rivers abound in fish. The country is peopled to the sea-shore; but the inhabitants are thinly scattered over its surface in temporary villages; and near many of the mouths experience great inconvenience from the want of fresh water, which they bring from a distance for themselves and cattle: the banks of the Gora form the only exception. The people consist chiefly of erratic and pastoral tribes; for though the Indus presents such facilities to the cultivator, there is not a fourth of the cultivable land below Tatta brought under tillage; it lies neglected and overgrown with tamarisk.
CHAP. V.
ON THE DELTA OF THE INDUS.
Delta of the Indus.
Herodotus said of Egypt, that it was the “gift of the Nile;” the same may be said of the country at the mouths of the Indus. A section of the banks of the river shows a continued succession of earth, clay and sand in layers, parallel to one another; and deposited, without doubt, at different periods. It would be perhaps hazarding too much to state, that the whole of the Delta has been gradually acquired from the sea; but it is clear that the land must have greatly encroached on the ocean. Nothing is more corroborative of this fact than the shallowness of the sea out from the mouths of the Indus, and the clayey bottom and tinge of the water.
Inundation.
The country from Tatta, which stands at the head of the Delta, to the sea downwards, is in most parts influenced by the periodical swell of the Indus: the great branches of this river are of themselves so numerous, and throw off such an incredible number of arms, that the inundation is general; and in those places which are denied this advantage by fortuitous circumstances, artificial drains, about four feet wide and three deep, conduct the waters through the fields. The swell commences in the latter end of April, and continues to increase till July, disappearing altogether in September: a northerly wind is supposed to accelerate it. It begins with the melting of the snow in the Himalaya mountains, before the rainy season. At other times the land is irrigated with the Persian wheel, which is turned by a camel or bullock, and in general use every where. One eighth of the Delta may be occupied by beds of rivers and inferior streams. Ten miles from the sea, the country is so thickly covered with furze and bushes, that it is incapable of being brought under tillage. Close upon the sea coast, however, there is abundance of green forage, which furnishes pasture to large herds of buffaloes. These animals reward the herdsmen with an abundant supply of ghee; but his labour is incessant, for he must bring fresh water from the interior for himself and his herd.
