Many important experiments have been undertaken by the Station, of particular interest being those relating to soil building, the hybridization of sea-island cotton with some of the common short-staple varieties, fertilizer tests with potatoes, by which it has been shown that it is possible to raise as much as 266 bushels per acre on light, sandy soil such as that comprising the school-lands, while the average yield in the same part of Alabama is not more than 40 bushels to the acre.
Not only do these great practical difficulties lie in the way of applying the hybridization test, but even when this oracle can be questioned, its replies are sometimes as doubtful as those of Delphi. For example, cases are cited by Mr.
Very often the precise effect desired appears in due time; very often something unlooked for turns up; but nearly always the result is beautiful, whether or no it serve the operator's purpose. Besides effect, however, there is an utility in hybridization which relates to culture.

The dahlias have been derived from three or more original species, and been subjected to cultivation and hybridization in an ever-increasing scale for a century. The best varieties are only propagated in the vegetative way, by the roots and buds, or by grafting and cutting.
This is more and more apparent each year, when the fittest are still further developed by hybridization for survival and the indifferent species drop out of sight. We often think erroneously of the beauty of old-time gardens. This beauty was largely that of consistency of form with the architecture of the dwelling and simplicity, rather than the variety, of flowers grown.
Quite on the contrary, it explains the most intricate questions of hybridization, providing they do not transgress the limits of symmetrical unions. But in this realm nearly all results may be calculated beforehand, on the ground of the principle of probability. Only one more assumption need be discussed.
Cookson gave his leisure to hybridization, with such results as, in short, are known to everybody who takes an interest in orchids.
"We are glad to have the opportunity of laying before our readers the portrait of one of the most distinguished of transatlantic horticulturists, and one who, by his zeal, industry, and determination, has not only conferred lasting benefits on his native country, but has by his careful experiments in hybridization and fruit-culture laid the horticulturists of all nations under heavy obligations to him.
I advise my readers to be daring, even desperate. It is satisfactory to learn that Mr. Cookson intends to make a study of bi-generic hybridization henceforward. The common motive for crossing orchids is that, of course, which urges the florist in other realms of botany. He seeks to combine tints, forms, varied peculiarities, in a new shape.
