 a rapid and dense growth, and continues in bloom 

 almost throughout the year. 



When larger wind-breaks are required, to resist the 

 force of heavy and steady winds sweeping over the

2729. Wind-breaks running across the direction of the prevailing 



interior plains through mountain passes, the manna 

 gum, Eucalyptus viminalis, is used with advantage; 

 this species suffers much less from strong wind than 

 the more tender blue gum, Eucalyptus Globulus, which 

 is used for the same purpose iu the more equable 

 climate of the Coast Range hills. Both the red gum, 

 Eucalyptus rostrata, and the Lombardy poplar, Populus 

 nigra, var. Italica, are used iu the vineyard region near 

 Fresno, to check the force of the periodic north-winds. 

 Arundo Donax is also frequently grown around vine- 

 yards, particularly in the immediate vicinity of water. 

 The olive, European walnut, tig and almond are fre- 

 quently planted for the outside row of an orchard of 

 deciduous fruit trees, to act as a partial wind-break. 



Arundo Donax makes a charming shelter-hedge for 

 a suburban garden, being light and graceful in appear- 

 ance and not too exclusive, while answering all neces- 

 sary purposes by providing a certain amount of privacy.

WINTER GARDEN. In England, a very large glass, 

 structure suited for trees and plants that are not quite 

 hardy and require only a small amount of artificial heat 

 in winter. Winter gardens are especially adapted to 

 strong-growing plants from Australia and the Cape, as 

 acacias and araucarias. Himalayan rhododendrons, ca- 

 mellias and the hardier palms and tree ferns are also 

 favorite subjects. The term "winter garden" is practi- 

 cally unknown in America. The word is sometimes used 

 as synonymous with glass-house or conservatory.

WINTER PROTECTION, or preparing plants to with- 

 stand tlie winter (Figs. 2731-2742 ). All plants are usu- 

 ally hardy in their own habitat, but many become tender 

 when removed to a colder climate, requiring artificial pro- 

 tection. A permanent covering of snow furnishes ideal 

 protection, hut unfortunately our American winters are 

 very changeable. Continued, steady cold is seldom in- 

 jurious, but the alternate freezing and thawing towards, 

 spring are often fatal, the damage varying according as 

 the situation is wet or dry and the soil light or heavy. 

 For example, shallow-rooted plants, as Lobelia cardi- 

 nalis, will often be thrown out of the ground in clayey 

 soil. Such damage may be prevented by placing sods 

 over the plants. Qaillardias will winter safely in light, 

 well-drained soils with ordinary protection, but perish 

 if wet and heavy. The remarks in this paper are meant 

 to apply in the vicinity of Chicago. 



Winfer covering intercepts the sun's rays and retards 

 premature activity. It is as essential "to keep in the 

 cold " during temporary warm spells as it is to retard ex- 

 cessive depth of frost. More damage is generally done 

 in February and March than earlier. Roses and other 

 shrubs may be prepared for the winter any time from 

 the last half of November until well into December, 

 but anything of an herbaceous nature may be covered 

 much earlier. Where field mice are troublesome it is 

 well to defer covering until after a good freeze, so that 

 these nibblers may seek other winter quarters. Rabbits 

 are fond of the Japan quince. Spiraea Van Houttei,
