On the whole, the linen trade of Belgium, notwithstanding its extensive preparation of machinery, and the extraordinary demand for its flax, must be regarded as in anything but a safe or a permanent position. In those stronger articles which can be made from flax of English growth, the English considerably undersell her already; an important trade is, at this moment, carried on in the north of Ireland in exporting linen goods to Germany, whence they were formerly imported into England, and whence they are still sent into Belgium, where the damask trade of Courtrai, which has been perpetually declining since 1815, is now, all but superseded by the weavers of Saxony and Herrnhut; and the tickens of Turnhout, by those woven from the strong thread of Brunswick. The contemplated measure of the French government, to impose a heavy duty on the importation of linen-yarn, will, if persevered in, be most prejudicial to the spinners of Belgium, as more or less, it must inevitably diminish their consumption. On the other hand, as England herself may be said to grow no flax for her own manufacture, and that of Ireland is not only far inferior in quality to the Dutch and Belgian, but inadequate to her own consumption, and every year increasing in demand and rising in price,--so long as Great Britain is thus dependant upon her own rivals for a supply of the raw material to feed her machinery, at an expense of from 8 to 10 per cent, for freight and charges, in addition to its high first cost, and whilst she must, at the same time, compete with them in those continental markets, which are open to them both, the spinning mills of Belgium cannot but be regarded otherwise than as formidable opponents. Nor is this apprehension diminished by the fact, that Belgium, which a few years since had no machinery for spinning yarn, except what she obtained from other countries, or could smuggle from England at a serious cost, is now enabled to manufacture her own, and has all the minerals, metals, and fuel within herself, which combined with industry and skilled labour, are essential to bring it to perfection. For the present, the English manufacturer, has a protection in the cost of his machinery alone--the factory of the _Société de la Lys_ cost £80,000 to erect, which supposing its 10,000 spindles to be in action, would be £8 per spindle, and as only the one half of these are at present employed, the actual cost is sixteen pounds; whilst an extensive mill can be erected in Ireland for from £4 to £5, and in England for even less. The difference of interest upon such unequal investments, must be a formidable deduction from the actual profits of the Belgians.
