Seite 134 - Manure is ineffectual towards vegetation, until it become soluble in water ; and it would remain useless in a state of solution, if it so abounded as utterly to exclude air ; for in that case, the fibres or mouths of plants would be unable to perform their functions, and they would soon drop off by decay.
Seite 84 - If the cortical layers be injured or destroyed by accident, the part is again regenerated, and the wound healed up, without a scar. If the wound have penetrated beyond the liber, the part is incapable of being regenerated ; because, when the surface of the alburnum is exposed to the air for any length of time, there will be no further vegetation in that part. But if the wound be not very large, it will close up, first, by the production of new bark, issuing from the edges, and gradually narrowing...

Seite 82 - ... upright. Our author has enumerated four properties which nature has taught trees that stand unsheltered to acquire by their own efforts, in order to suit themselves for their situation. First, thickness and induration of bark ; secondly, shortness and girth of stem ; thirdly, numerousness of roots and fibres ; and fourthly, extent, balance, and closeness of branches. These, Sir Henry has denominated the four protecting qualities ; and he has proved, by a very plain and practical system of reasoning,...
Seite 95 - Their development is most luxuriant in ground that is neither too loose nor too dense. In stiff and poor soils they are spare and scraggy; whereas in such as are at once deep and loose, the minutest fibres both expand and elongate with facility, and render the mouths that search for food to the plant almost innumerable.
Seite 410 - The general effects of pruning I have already stated to be of a corresponding nature with those of culture — that is, to increase the quantity of timber produce. The particular manner in which it does this is by directing the greater part of the sap, which generally spreads itself in side-branches, into the principal stem. This must consequently enlarge that stem in a more than ordinary degree, by increasing the annual circles of the wood.
Seite 64 - ... forced efforts to secure as much of the beneficial influence as it can, and to accommodate itself to the exigency of its situation. Thus, where light is admitted only from a single point, a plant concentrates all its powers, in stretching towards the direction of the light. Where light is shed all around, the plant throws out its branches on every side. In conformity with this principle, we find, that, in the interior of a wood, where the Trees mutually impede the lateral admission of light,...
Seite 14 - ... could be procured, placed on the eastern bank, above the water, broke it into parts with their spreading branches, and formed combinations which were extremely pleasing. The copse or underwood, which covers an island in the lake, and two promontories, as also an adjoining bank that terminates the distance, was seen coming down nearly to the water's edge. What was the most important of all, both trees and underwood had obtained a full and deepcoloured leaf, and health and vigour were restored...
