The scales which form the female catkin are of a whitish green; the bractea on the back is slightly reddish on its upper side; and the stigma, which has two points, is of a bright red. After fertilization, the scales augment in thickness; and, becoming firmly pressed against each other, they form by their aggregation a fruit, which is three years before it ripens.
"Of these, Mother is heir to five hundred and fifty acres, leaving one thousand one hundred acres to be divided among sixteen of us, which give sixty-eight and three-fourths acres to each. This land is the finest that proper fertilization and careful handling can make. Even the poorest is the cream of the country as compared with the surrounding farms.
The chain of circumstances is as follows: the quality of the clover fields, furnishing the best food for cattle, depends largely upon the visits to the clover-blossoms by wild bees, that accomplish the fertilization of the flowers by carrying pollen upon their bodies from one plant to another.
But if the germ-plasm has this constitution and relation to the rest of the body, how is any variation possible? Different individuals of any species have slightly different congenital tendencies. Hence in the act of fertilization two germ-plasms of slightly different structure and tendency are mingled.
It is not known exactly when this discharge of ova takes place, but it is believed to coincide more or less with the monthly period. If, however, fertilization of the ovum takes place, it is not discharged, but remains in the uterus.
These ashes would under other circumstances have to be purchased at a cost of perhaps two dollars a barrel, and as five barrels at least to the acre are required for good fertilization, these ashes gave us the first credit upon the books. Following the burners came the manure spreaders; five carloads of manure had been purchased and was delivered before it was needed.
I go about the house, up steep, worn stairs, down again and out into a garden where there is a single strawberry and I think staminate and pistillate plants should be set out to insure fertilization. Always I think of the closed door and presently I return to the house and enter the room behind the stove. On the floor is a green veil of firm texture.
In this way, it is made sure that some of them will travel up through the uterus and oviducts, arriving in the neighborhood of the ovaries. FERTILIZATION. Convincing observations upon the lower forms of life, especially upon fishes, have shown that when the germinal cells come near to each other, the ovum attracts the spermatozoon.
Many ignorant overseers of large land holdings knew little of fertilization or replenishing the soil and they too, when they had exhausted one part of the proprietorship, moved on to another, which they cleared by burning.
Here too, is a field where the young botanist can do really valuable work, for while much is known and has been written on the subject, much remains unknown. There are many books that give valuable and delightful information about cross-fertilization. The method of fertilization of the flowers satisfactorily accounts for the great amount of pollen produced.
