On the belief that this is a law of nature, we can, I think, understand several large classes of facts, such as the following, which on any other view are inexplicable. Every hybridizer knows how unfavourable exposure to wet is to the fertilisation of a flower, yet what a multitude of flowers have their anthers and stigmas fully exposed to the weather! but if an occasional cross be indispensable, the fullest freedom for the entrance of pollen from another individual will explain this state of exposure, more especially as the plant's own anthers and pistil generally stand so close together that self-fertilisation seems almost inevitable. Many flowers, on the other hand, have their organs of fructification closely enclosed, as in the great papilionaceous or pea-family; but in several, perhaps in all, such flowers, there is a very curious adaptation between the structure of the flower and the manner in which bees suck the nectar; for, in doing this, they either push the flower's own pollen on the stigma, or bring pollen from another flower. So necessary are the visits of bees to papilionaceous flowers, that I have found, by experiments published elsewhere, that their fertility is greatly diminished if these visits be prevented. Now, it is scarcely possible that bees should fly from flower to flower, and not carry pollen from one to the other, to the great good, as I believe, of the plant. Bees will act like a camel-hair pencil, and it is quite sufficient just to touch the anthers of one flower and then the stigma of another with the same brush to ensure fertilisation; but it must not be supposed that bees would thus produce a multitude of hybrids between distinct species; for if you bring on the same brush a plant's own pollen and pollen from another species, the former will have such a prepotent effect, that it will invariably and completely destroy, as has been shown by G?rtner, any influence from the foreign pollen.When the stamens of a flower suddenly spring towards the pistil, or slowly move one after the other towards it, the contrivance seems adapted solely to ensure self-fertilisation; and no doubt it is useful for this end: but, the agency of insects is often required to cause the stamens to spring forward, as K?lreuter has shown to be the case with the barberry; and curiously in this very genus, which seems to have a special contrivance for self-fertilisation, it is well known that if very closely-allied forms or varieties are planted near each other, it is hardly possible to raise pure seedlings, so largely do they naturally cross. In many other cases, far from there being any aids for self-fertilisation, there are special contrivances, as I could show from the writings of C. C. Sprengel and from my own observations, which effectually prevent the stigma receiving pollen from its own flower: for instance, in Lobelia fulgens, there is a really beautiful and elaborate contrivance by which every one of the infinitely numerous pollen-granules are swept out of the conjoined anthers of each flower, before the stigma of that individual flower is ready to receive them; and as this flower is never visited, at least in my garden, by insects, it never sets a seed, though by placing pollen from one flower on the stigma of another, I raised plenty of seedlings; and whilst another species of Lobelia growing close by, which is visited by bees, seeds freely. In very many other cases, though there be no special mechanical contrivance to prevent the stigma of a flower receiving its own pollen, yet, as C. C. Sprengel has shown, and as I can confirm, either the anthers burst before the stigma is ready for fertilisation, or the stigma is ready before the pollen of that flower is ready, so that these plants have in fact separated sexes, and must habitually be crossed. How strange are these facts! How strange that the pollen and stigmatic surface of the same flower, though placed so close together, as if for the very purpose of self-fertilisation, should in so many cases be mutually useless to each other! How simply are these facts explained on the view of an occasional cross with a distinct individual being advantageous or indispensable!If several varieties of the cabbage, radish, onion, and of some other plants, be allowed to seed near each other, a large majority, as I have found, of the seedlings thus raised will turn out mongrels: for instance, I raised 233 seedling cabbages from some plants of different varieties growing near each other, and of these only 78 were true to their kind, and some even of these were not perfectly true. Yet the pistil of each cabbage-flower is surrounded not only by its own six stamens, but by those of the many other flowers on the same plant. How, then, comes it that such a vast number of the seedlings are mongrelised? I suspect that it must arise from the pollen of a distinct variety having a prepotent effect over a flower's own pollen; and that this is part of the general law of good being derived from the intercrossing of distinct individuals of the same species. When distinct species are crossed the case is directly the reverse, for a plant's own pollen is always prepotent over foreign pollen; but to this subject we shall return in a future chapter.
OUTDOOR SPACE: The house is on a fifth of an acre, landscaped by the New York firm Landgarden. The Japanese-style gardens in front make use of native plants. There’s also a back patio and yard, with a second Japanese garden.
He stood at Miss Temple's side; he was speaking low in her ear: Idid not doubt he was making disclosures of my villainy; and Iwatched her eye with painful anxiety, expecting every moment to seeits dark orb turn on me a glance of repugnance and contempt. Ilistened too; and as I happened to be seated quite at the top of theroom, I caught most of what he said: its import relieved me fromimmediate apprehension.

3、 Under colour of Confession, and of a most pure conscience, a faireyong Gentlewoman, being amourously affected to an honest man,induced a devoute and solemne religious Friar, to advise her in themeanes (without his suspition or perceiving) how to enjoy thebenefit of her friend, and bring her desires to their full effect.

The Woman immediately made answer, it was not true, that she wasin love with any Fryar. How? quoth Geloso, didst not thou confesseso much to the Ghostly Father, the other day when thou wast at shrift?No Sir, sayde she, but if I did, I am sure he would not disclose it toyou, except hee suffered you to bee there present, which is an Articlebeyonde his dutie. But if it were so, then I confesse freely, that Idid say so unto him. Make an end then quickely Wife (quoth Geloso) andtell mee who the Friar is. The Woman fell into a hearty laughter,saying. It liketh me singularly well, when a wise man will sufferhimselfe to be ledde by a simple Woman, even as a Sheepe is to theslaughter, and by the hornes. If once thou wast wise, that wisedomebecame utterly lost, when thou felst into that divellish frensie ofjealousie, without knowing anie reason for it: for, by thisbeastlike and no manly humor, thou hast eclipsed no meane part of myglory, and womanly reputation.[回复]
