"Now it is the inclination of the Earth's axis, as above described, which causes the lengths of the days and nights to differ at the same place at different seasons of the year, for on reviewing the positions of the globe at A, it will be observed that the line formed by the enlightened and dark hemispheres, does not coincide with the line of the axis and the pole, but that the line formed by the darkness and the light, extends obliquely across the line of the Earth's axis, so that the north pole is in the light while the south is in the dark. In the position A, therefore, an observer at the north pole would see the sun constantly, while another at the south pole would not see it at all. Hence those living in the north temperate zone, at the season of the year when the earth is at A, or in the Summer, would have long days and short nights, in proportion as they approached the polar circle; while those who live in the south temperate zone, at the same time, and when it would be Winter there, would have long nights and short days in the same proportion." —Comstock, 1850

"Some plants, like pelargoniums, can only be kept handsomely formed and well furnished by cutting them down severely every season, after the blooming is over. The plants should be prepared for this by keeping them rather dry at the root, and after cutting they must stand with little or no water till the stems heal over, and produce yound shoots, or "break," as it is technically termed." — Encyclopedia Britannica, 1893

"Summer and Winter rays.—Let us suppose that the rays falling perpendicularly on a given extent of surface, impart to it a certain degree of heat, then it is obvious, that if the same number of rays be spread over twice that extent of surface, their heating power would be diminished in proportion, and that only half of the heat would be imparted. This is the effect produced by the Sun's rays in the Winter. They fall so obliquely on the Earth, as to occupy nearly double the space that the same number of rays do in the Summer." —Comstock, 1850

"Suppose the Earth to be in her Summer solstice, which takes place on the 21st of June. At this period she will be at a, having her north pole, n, so inclined towards the Sun, that the whole arctic circle will be illuminated, and consequently the Sun's rays will extend 23.25 degrees, the breadth of the polar circle, beyond the north pole." —Comstock, 1850

"Summer Pruning should be performed while the shoots are yet young and succulent, so that they may be in most cases be nipped off with the thumb-nail. It is very necessary in the case of trees trained to a flat surface, as a wall or espalier rail, to prevent undue crowding. In some cases, as, for example, with peaches, the superfluous shoots are wholly removed, and certain selected shoots reserved to supply bearing wood for the next year." — Encyclopedia Britannica, 1893

"Pea weevil; adult. The pea weevil (Bruchus) is often found in peas in its larval state during summer and autumn, as a pupa in winter, and in the adult form in late spring, when it comes forth to lay its eggs on the pods of the growing peas. To find the weevil in the fall, soak peas in water for a day." —Davison, 1906
