Beside these two precious products, Chaldaea produced excellent barley, millet, sesame, vetches and fruits of all kinds. It was, however, deficient in variety of trees, possessing scarcely any but the palm and the cypress. Pomegranates, tamarisks, poplars, and acacias are even now almost the only trees besides the two above mentioned, to be found between Samarah and the Persian Gulf. The tamarisk grows chiefly as a shrub along the rivers, but sometimes attains the dimensions of a tree, as in the case of the “solitary tree” still growing upon the ruins of Babylon. The pomegranates with their scarlet flowers, and the acacias with their light and graceful foliage, ornament the banks of the streams, generally intermingled with the far more frequent palm, while oranges, apples, pears, and vines are successfully cultivated in the gardens and orchards. [Illustration: PLATE 5] Among the vegetable products of Chaldaea must be noticed, as almost peculiar to the region, its enormous reeds. [PLATE V.] These, which are represented with much spirit in the sculptures of Sennacherib, cover the marshes in the summer-time, rising often to the height of fourteen or fifteen feet. The Arabs of the marsh region form their houses of this material, binding the stems of the reeds together, and bending them into arches, to make the skeleton of their buildings; while, to form the walls, they stretch across from arch to arch mats made of the leaves. From the same fragile substance they construct their _terradas_ or light boats, which, when rendered waterproof by means of bitumen, will support the weight of three or four men.
