Rh 380 AGRICULTURE [FLAX. When it is desired to save the seeds of Italian or common ryegrass, the crop, after being mown, is allowed to lie for a day or two in swathe, and is then neatly gathered into sheaves, bound, and stooked, precisely like a crop of oats. When sufficiently dried, the seed is either thrashed out in the field, the straw stacked like other hay, and the seed spread thinly over a granary floor, and turned several times daily until it is dry enough to keep in a bin or in sacks ; or the sheaves are built into small round stacks, which stand until the seed is wanted, when it is thrashed out by machinery like grain. Of late years we have frequently secured considerable quantities of useful hay by mowing seeds that had been pastured by sheep in the early part of the season. In July we run the mowing-machines over such fields, taking care to set the cutting-bar high enough to leave the fresh-grown herbage untouched, and to remove only that of older and taller growth. The mown stuff is left untouched for two or three days ; is then drawn together by the horse rake, and put into cocks for a short time, or carted at once to the rick-yard as weather permits. In this way much herbage that would otherwise go to waste is converted into useful winter fodder, and a fresh-grown clean pasture secured for lambs or other stock. CHAPTER XIV. CULTIVATED CROPS CROPS OF LIMITED CULTIVATION. Under this head we shall notice a variety of crops which, Lowever valuable in themselves, and important to the farmers of particular localities, are, from one cause or other, not adapted for general cultivation. Section 1. Flax. Flax is probably the most important of these crops. In deed, from the rapid growth of our linen trade, the growing demand for linseed and its products, and the fitness of the soil and climate for the successful growth of flax, it is not without cause that its more extended cultivation has been so strenuously urged upon our farmers, and that influential societies have been organised for the express purpose of promoting this object. Viewed merely as an agricultural crop, the cultivation of flax is exceedingly simple, and could be practised as readily and extensively as that of the cereal crops. The difficulty is, that before it can be disposed of to any advantage, it must undergo a process of partial manufacture ; thus there is required not only an abundant supply of cheap labour, but such an amount of skill and personal superintendence on the part of the farmer as is incompatible with due attention to corn and cattle husbandry. If a ready and remunerative market were available for the fibre in its simple form of flax straw, this, in combination with the value of the seed for cattle feeding, would at once hold out sufficient motive to our farmers to grow it statedly and to any required extent. Until this is the case, its culture cannot extend in the corn-growing districts of Great Britain. In Ireland and parts of the Highlands of Scotland, where there is a redundant popula tion much in want of such employment as the flax crop furnishes, and where the climate is suited for its growth, it is highly desirable that its culture should extend, and probable that it will do so. Flax prospers most when grown upon land of firm texture resting upon a moist subsoil. It does well to succeed oats or potatoes, as it .requires the soil to be in fresh condition without being too rich. Lands newly broken up from pasture suit it well, as these are generally freer from weeds than those that have been long under tillage. It is usually inexpedient to apply manure directly to the flax crop, as the tendency of this is io produce over-luxuriance, and thereby to mar the quality of the fibre, on which its value chiefly depends. For the same reason it must be thickly seeded, the effect of this being to produce tall slender stems, free from branches. The land having been ploughed in autumn, is prepared for sowing by working it with the grubber, harrow, and roller, until a fine tilth is obtained. On the smooth surface the seed is sown broadcast by hand or machine, at the rate of 3 bushels per acre, and covered in the same manner as clover seeds. It is advisable immediately to hand-rake it with common hay-rakes, and thus to remove all stones and clods, and to secure a uniform close cover of plants. When these are about 3 inches long the crop must be carefully hand-weeded. This is a tedious and expensive process, and hence the importance of sowing the crop on land as free as possible from weeds of all kinds. To obtain flax of the very finest quality the crop must be pulled as soon as the flowers fall, but in the improved modes of steeping, whether by Schenck s or Watt s patent, the value of the fibre is not diminished by allowing the seeds to mature. It must not, however, be allowed to become dead ripe, but should be pulled whenever the seeds appear, on opening the capsule, to be slightly brown-coloured. The pulling requires to be managed with much care. It is performed by men or women, who seize a small quantity with both hands and pull it by a slight jerking effort. The important point to be attended to is to keep the butts even as successive quantities are seized and twitched from the ground. When a convenient handful has been pulled it is laid on the ground, and the next parallel to it at a foot or so apart. The next handfuls are laid across these, and so on until a small pile is made, after which another is begun. After lying in this position for a few days, the seed-vessels or bolls are separated from the flax by lifting each handful separately and pulling the top through a ripple or iron comb fixed upon a piece of plank. As many of these handfuls as will make a small sheaf are then laid very evenly together, and bound near both ends with bands formed of a few stems of flax. These sheaves are set up in stocks, and when dry enough to keep without heating are stacked and thatched until an opportunity occurs of disposing of the flax straw. Sometimes the flax is bound into sheaves and stooked as it is pulled, and treated exactly like a grain crop. In this case the seed is separated from the straw by passing the head of each sheaf between iron rollers. The only objection to this plan is that the bolls of separate sheaves get so entangled in each other as to render it exceedingly difficult to handle them in carrying the crop, and in building and taking down the stacks, without dis arranging the sheaves and wasting much straw and seed. It would be tedious to enter here into a minute detail of the ordinary method of separating the flax fibre from the woody part of the stem. Suffice it to say that in the ordinary practice the sheaves or beets of flax straw are immersed in a pit or pool filled with clear soft water. The sheaves are kept under water by laying boards upon them loaded with stones to keep them down. Here the flax undergoes a process of fermentation by which the parts are separated. About nine or ten days are usually required for this purpose, but this is much influenced by the temperature. A good deal of skill and close watching is required to know exactly when it has been watered enough. The flax is now taken from the pit and evenly spread upon a smooth, clean, recently-mown meadow, where it lies for about ten days more, receiving several turnings the while. When the retting, as this is called, is perfected, the flax is carefully gathered up when perfectly dry, and again tied into sheaves, in which state it is stored under cover until the breaking and scutching can be overtaken. All this necessarily requires much skilful watching and nice manipulation, more, as we have already said, than is
