And here lies the danger of the opium crop: should a shower of heavy rain descend the product is absolutely nil, the exuded opium being all washed away by the rain. All around Ispahan, where there is good land, and it is not exhausted, nothing can be seen for miles but these fields of white poppies, and the scenery is thus rendered very monotonous.
The Persian farmer is fully alive to the value of manure, and makes it in a very simple manner. All the wood-ashes collected from a house, and the rest of the refuse-heap, are placed in the open street in a circular ridge mixed with mould. Into this is poured the contents of the cesspools, which are allowed to sink into the thirsty heaps of earth and ashes. The “koot,” or manure thus formed, is removed to the fields, allowed to dry in the sun, then mixed with more earth, and after a month or two scattered equally over the soil and dug in.
Barley—which is used for the feeding of horses and mules, to the exclusion of oats, which are never grown—rice, and wheat, are cultivated largely. The barley of Persia is very fine; the wheat grown is the red variety. Beans, pulse, clover, sesamum, maize, cotton, castor-oil plant, cunjeet (a sort of colza), and nokōd, a grain like a pea, which is much used in cookery; potatoes, lettuces, spinach, are all largely raised. Tobacco, olives (near the Caspian), melons, and cucumbers form the rest of the crops; and millet is also grown.
Quite one half of the barley is cut as grass for the horses, and not allowed to ripen. Tares are grown for the same purpose and cut green.
The harvest of wheat and barley is cut with the sickle, the whole crop being cast pell-mell in a heap in the centre of the field, perhaps some twenty feet high; there it is allowed to lie for a month, or till it is convenient to the owner to extract the grain. This is done by laying round the heap a small quantity of straw with the ear on, and going over it with a kind of car made with heavy beams and running on rollers fitted with sharpened edges of iron; a boy rides on this, and, with a rope and a stick, guides a pair of oxen, or a mule and a horse, or a mule and a donkey, which draw this very primitive machine. As the straw gets broken, more is added, and the broken straw and ears dragged to the side with the grain entangled among them; the weather being very dry, the grain generally all falls out ere this crushing process commences. The straw is in this way crushed into pieces some two or three inches long. When the whole heap has been gone over, the farmer waits for a windy day; when it comes, he tosses the heap in forkfuls in the air. The cut straw is carried a yard or two, and the grain being heavier falls straight to the ground and is removed: the straw is now termed “kah,” and is stored; it is the ordinary fodder of the country, hay being seldom used, save by the rich.
It is also useful as a packing material and to make the “kah-gil” (“gil,” clay), a kind of plaster with which all houses, save those built of burnt bricks, are smeared, and with which all roofs in Ispahan, Teheran, and Shiraz are carefully coated: it is not until Ghilān, on the Caspian shore, is reached that we come to tiled roofs. Mud bricks are also made with mud and old or spoiled kah. It is doubtless for this that the Jews desired straw of the Egyptians to make their bricks.
Sheep are never fed on clover in sitû, it is considered too precious (it is cut and dried in twists some two yards long); but they are, however, allowed to graze on the stubble of wheat and barley, and so manure the land.
The greater part of the country is irrigated (save near the Caspian, where the water is in such excess that men may be seen ploughing up to their knees in it); consequently the fields are made up into small squares or parallelograms by trenches raised with the spade; these parallelograms run on each side of a small trench, from which the water is admitted, and as fast as one is opened and filled from the trench, it is stopped, and water admitted to another, and so on until the whole field is thoroughly soaked. Of course it is impossible to ride over a recently watered field, as, if the soil is light, one’s horse is soon up to his girths.
Land in Persia is of value according to the quantity of water it is entitled to, and the great cost of a crop is usually not the amount of labour bestowed or the rent paid, but the quantity of water purchased.
