Wind
The various points from which the Wind proceeds, and the amount of its force, are matters requiring daily consideration in the proper management of glass structures, and for the preservation against injury of plants and trees outside. The damage caused by a rough gale is often of a most disastrous nature; sometimes large and valuable trees are uprooted, or have their branches torn off, causing permanent disfigurement. In different localities and situations, what are known as the prevailing Winds have to be taken into account in planting operations: in some, the gales most frequently proceed from one particular point-south-west, for instance-while in others, a wood, hill, or large belt of trees may afford protection from that, but not from some other direction. Situations on various parts of the sea-coast, and also inland, will be locally affected in regard to prevailing Winds. The destruction caused by the Wind to fruit crops is, unfortunately, to familiar. Newly-planted trees of all kinds, of sufficient size to be rocked to and fro by the force of the Wind, should always be secured will stakes for the first season, after which their roots will have generally taken a good hold, thus rendering them safe. Plants in pots-Chrysanthemums, for example-are soon destroyed by a gale if not securely staked and tied. A cold Wind has a most injurious effect on the tender foliage of trees and plants in glass structures, particularly in early spring, when too frequently it proceeds from an easterly or north-easterly direction. Preventive measures should be adopted, as far as possible, beforehand, so that when the Wind's force is suddenly increased to a gale, everything may be secured against injury. Not unfrequently, the proper provision which it is necessary to make against rough weather is forgotten when trees are newly planted; or plants in pots are placed in exposed situations during a calm period; and the effects of the first rough Wind are disastrous.
