As Gartner found that there was sometimes an innate difference in different INDIVIDUALS of the same two species in crossing; so Sagaret believes this to be the case with different individuals of the same two species in being grafted together. As in reciprocal crosses, the facility of effecting an union is often very far from equal, so it sometimes is in grafting.
Insects act like a camel-hair pencil, and it is sufficient, to ensure fertilisation, just to touch with the same brush the anthers of one flower and then the stigma of another; but it must not be supposed that bees would thus produce a multitude of hybrids between distinct species; for if a plant's own pollen and that from another species are placed on the same stigma, the former is so prepotent that it invariably and completely destroys, as has been shown by Gartner, the influence of the foreign pollen.
In regard to the sterility of hybrids in successive generations; though Gartner was enabled to rear some hybrids, carefully guarding them from a cross with either pure parent, for six or seven, and in one case for ten generations, yet he asserts positively that their fertility never increased, but generally greatly decreased.
Brangwyn's heavy-muscled body, and his ease and grace in handling it, marked him as a man of a high-gravity planet. Besides, Hathor had a permanent cloud-envelope, and Tom Brangwyn's skin had turned boiled-lobster red under the dim orange sunlight of Alpha Gartner.
That's a big enough market and a big enough labor force to exploit the wealth of the Gartner Trisystem. We can have prosperity for everybody on our own resources. Just what do we need that we have to get from outside now?" His father stopped again and sat down on the edge of a fountain the same one, possibly, from which Conn had seen dust blowing as the airship had been coming in.
If nothing important occurs on Monday, on Tuesday I shall reach you; but, if the trouble begins, I should still like to stay near the King. You received no letter from me today, because I sent a report about the society to Gärtner, and you will learn from him that I am all right. You will receive this tomorrow, and I shall write again on Monday. Send horses for me on Tuesday.
For instance, the blue and red pimpernel, the primrose and cowslip, which are considered by many of our best botanists as varieties, are said by Gartner not to be quite fertile when crossed, and he consequently ranks them as undoubted species. If we thus argue in a circle, the fertility of all varieties produced under nature will assuredly have to be granted.
I am strengthened in this conviction by a remarkable statement repeatedly made by Gartner, namely, that if even the less fertile hybrids be artificially fertilised with hybrid pollen of the same kind, their fertility, notwithstanding the frequent ill effects of manipulation, sometimes decidedly increases, and goes on increasing.
I shall here discuss this subject with extreme brevity. The most important distinction is, that in the first generation mongrels are more variable than hybrids; but Gartner admits that hybrids from species which have long been cultivated are often variable in the first generation; and I have myself seen striking instances of this fact.
The celebrated Klenze is known throughout Europe as the first of living architects, and the favourite of his sovereign when that sovereign did not wear a crown; but we must not forget the name of Gartner, the architect who has revived the Byzantine style of building with such admirable effect.
