come up at the same time; sorts may differ in this respect, but especially do old and new seeds vary as to their germinating powers: two-year-old seeds taking four or five days more to come up than a new sample; thus giving a greater chance for the ravages of the flea-beetle than where the seed all comes up quickly.
Now, as a practical application of these remarks, we here quote from an article in the Agricultural Gazette of May 24th, 1862.
Who among seedsmen does not profess to offer the seeds of swedes and turnips from selected bulbs? And though it is quite true that the practice is not so universal as is the profession of it, yet the general assumption of its being so on the part of seed growers and sellers is an admission that it would be for the advantage of the buyer of seeds were the roots from which seeds are to be grown carefully selected. And on the other hand, let the observant agriculturist take a journey on any of our great lines of railway (in early summer), and he will be struck with the many patches of bright yellow flowers which he will not fail to notice on either hand. In nine cases out of ten, these are fields or portions of fields of turnips, either the Swedish or common kinds, which, from the abundance of keep, it has been thought would be more profitable to seed than to eat off, especially as they have so rapidly grown out of the way. Are these patches of selected bulbs? We happen to know, from a more than ordinarily careful examination, that not one per cent. of seeding-patches are from selected roots; but they are seeded just as they grew, and we do not know of a single instance where in such seeding the objectionable roots have been removed; but we do know of plenty of cases where the worst part of a field has been saved for seed, doubtless as the most profitable way of dealing with it under the circumstances wrought out by the spring of 1862.
Of course, this will all come into the market, and too much of it, under a stereotyped declaration of ‘from selected bulbs.’ That all the seed grown in 1862 will be sown in 1863 is simply impossible; but no matter, it will find a market somehow, some time. With such facts as these before us, who can wonder that any plant should become degenerate? Let some of the seed of this year be watched,[17] and we will answer for its evil results; and if these be facts, it then behoves the farmer to look well to pedigree in the matter of his seed.
But even here, his forethought must not end; for however select the parent may be, there is still something in ‘bringing up;’ for, however good the sort of turnip, we shall not grow its seed in perfection by selection merely, but we should transplant well-chosen roots, and so put them in a new scene, away from subjects which might contaminate them. This is indeed to bring them up in a good school, for which their seed will amply repay the trouble and expense.
CHAPTER IV.
ON DEGENERATE ROOTS.
If the reader revert to page 6, Fig. 3, he will see that the progress from a wild to a better root-form is marked by a more fleshy, but still a much forked, or finger-and-toed example. Now as it is held that a clear unbranched outline is essential to a well-formed root crop of every kind, whenever a crop becomes fingered-and-toed, it is looked upon as a disease. It must be understood that we are here speaking of finger-and-toe as distinct from anbury, which latter is a decidedly diseased condition, whether caused by insects or resulting, as some affirm, from a defect in the soil.
The difference in the two states may be briefly summed up as follows:—
| Finger-and-Toe. | Anbury. |
| Root simply branched or forked, with tapering fleshy rootlets; occurs in turnips, parsnips, carrots, and mangold. (See figs. 1, 2, 3, 5, 6, 7, 8, 9, 10.) | Root infested with irregular nodular protuberances, or with tumours suspended by roots, having very much the aspect of rows of ginger; occurs in turnips alone. (See fig. 12.) |
The example of a root at page 6 is a good form of a parsnip progressing from wildness to a better cultivated form. We now offer an engraving (fig. 5) of a hollow-crowned crop parsnip, fingered-and-toed, and evidently of a very objectionable form, as it will be seen on comparison how nearly alike are figs. 3 and 5.
