עמוד 7 - God Almighty first planted a garden; and, indeed, it is the purest of human pleasures. It is the greatest refreshment to the spirits of man; without which buildings and palaces are but gross...
עמוד 296 - ... thought them liable to be injured. But, when I had learned, that bodies on the surface of the earth become, during a still and serene night, colder than the atmosphere, by radiating their heat to the heavens, I perceived immediately a just reason for the practice, which I had before deemed useleu. Being desirous, however, of acquiring some precise information on this subject...
עמוד 284 - ... situation in which it is kept, is of importance. It should, if possible, be defended from the sun. To preserve it under sheds would be of great use ; or to make the site of a dunghill on the north side of a wall. The floor on which the dung is heaped should, if possible, be paved with flat stones ; and there should be a little inclination from each side towards the centre, in which there should be drains connected with a small well, furnished with a pump, by which any fluid matter may be collected...

The expansion of water during its congelation, at which time its volume increases...
עמוד 263 - And when the leaves are fully developed, the ground is shaded, and any injurious influence, which in the summer might be expected from too great a heat, entirely prevented ; so that the temperature of the surface, when bare and exposed to the rays of the sun, affords at least one indication of the degrees of its fertility; and the thermometer may be sometimes a useful instrument to the purchaser or improver of lands.
עמוד 275 - The great object in the application of manure should be to make it afford as much soluble matter as possible to the roots of the plant : and that in a slow and gradual manner, so that it may be entirely consumed in forming its sap and organised parts.
עמוד 223 - In the same manner the flowering has its regular time : the mezereon and snowdrop push forth their flowers in February ; the primrose in the month of March ; the cowslip in April ; the great mass of plants in May and June; many in July, August, and September ; some not till the month of October, as the meadow saffron ; and some not till the approach and arrival of winter, as the laurustinus and arbutus.
