For these reasons cases of atavism given without recording the circumstances, or the precautions that guarantee the purity of the fertilization, should always be disregarded. And moreover another proof should always be demanded. The parent which yielded the seeds might be itself a hybrid and liable to reversions by the ordinary laws of the splitting up of hybrids.
Those who have thoroughly assimilated the idea to be gained by a comprehension of this separation of the sun, will now be able to interpret correctly the significance of the process of plant fertilization, when it is said that “the plant previous to fructification is in a ‘sun state,’ and afterward in the ‘moon state.’ ” Indeed, it may be said of even the smallest occurrence in the world that it can be fully understood only when the reflection of great cosmic events is recognized in it.
The men dig shallow holes and set each plant upright, while the women follow, filling the hole with water and then pressing earth in with fingers or toes. The former is planted on the hillsides, where it matures in three or four months. The plant seldom reaches a height of two feet, and the bolls are small, doubtless due to lack of care and suitable fertilization.
Catalogne remarks in his valuable report that if the fields of France were cultivated like the farms of Canada three-fourths of the people would starve. Fertilization of the land was rare. All that was usually done in this direction was to burn the stubble in the spring before the land went under the plough. Rotation of crops was practically unknown.
The ox may select the richest pasture; but never dreamed of creating a rich pasture by the culture and fertilization of which he is the chief source. The tiger chooses and slays his prey; but does not know how to propagate, develop, and safely mature the animals on which he feeds.
But these were only occasional admixtures, since after artificial fertilization of the typical specimens the strain at once became absolutely pure, and remained so for a series of generations, as long as the experiment was continued.
Apparently it was a scientific paper on a rather unusual subject, "Spontaneous Generation of Life." It was in longhand and read: *Many thanks for the copy of the paper by Prof. Betallion of Dijon on the artificial fertilization of the eggs of frogs. I consider it a most important advance in the artificial generation of life. *In the printed book this is shown as handwritten
Before pregnancy can take place there must be a meeting and fusion of the vital elements of the two sexes. This fertilization of the ovum or joining of the male and female elements is called conception. It is brought about by coitus, by means of which the semen of the male is deposited in the vagina of the female. When this occurs the woman conceives and enters upon a period of pregnancy.
Granting these premises, we may now ask as to the results of the fertilization of hybrids, when this is brought about by their own pollen. We assume that numerous pollen grains fertilize numerous egg cells.
Vegetables which behave like your tomatoes and string beans, making too much growth and not enough fruit, do not need fertilization. The land is perhaps too rich already, or you may have used too much water. Use less water so that the plants will make a more moderate growth, and they will be fruitful if the season is warm enough in the later part of summer.
