Our next inquiry was for a sample of 000 seed itself; but, although it is well known in the trade, we have hitherto failed in procuring it. We had hoped that our seedsmen might have been able to procure some through some of their friends. The result was, that we made application to a most respectable London firm, receiving the following reply:— LONDON, _February 27, 1861_. SIR,—In reply to your favour received this morning, we take leave to say that we shall have pleasure in complying with your request for a sample of 000 turnips, if we can obtain it. But we do not keep it ourselves, nor do we know the parties who prepare it, it being something of a trade secret. We will, however, apply to some of our friends here to let us have a small quantity, but doubt if they will let us have it, as it is a matter they are rather chary respecting, and _although perfectly well known and understood in the trade, they do not care to have it known beyond_, and our asking for a small quantity will be sure to lead to the question, “What do we want it for?” We could obtain a large quantity without hesitation. We remain, &c., —— The sentence we have placed in italics will be quite sufficient to show how well the matter of 000 seeds is understood in the trade, and how easy it is to get bushels of it, no questions being asked, while a small quantity, required only for investigation, may be refused. It appears, then, that the machinery exists by which any one in the seed trade may quietly and easily commit enormous frauds. And it is plain that the very notoriety of this machinery, together with the condition of many of the samples of seed which we have examined (see Chap. VI.) prove that this machinery actually is employed by many seedsmen to the great injury of their customers. We cannot, then, be doing wrong in urging any one to make trial of the seeds he is about to buy before he sows them, or even before he purchases them. Where the experience of a number of years already exists, the character of the seedsman is a guarantee for the good quality of his goods, and experience of this kind is indeed a more perfect carrying out of the system of preliminary trial or experiment, which we recommend especially to all new customers. CHAPTER VIII. ON THE INJURIES CAUSED BY INSECTS. Root-crops are especially liable to injury from the depredations of insects. Thus the turnip may have its seed more or less destroyed by weevils. Immediately the seed appears above the ground, commences the attack by the turnip flea-beetles. The bulb is pierced by beetles, ending in those excrescences called “turnip-warbles;” and there is reason to think that even the root-fibrils are in some soils made the depositories of the eggs of insects, which give rise to extraordinary malformations.
