108 Cultivation of Shade Trees. 
habits, they will mitigate, to a flattering extent, and we have 
known residences where sickness was almost a certain attendant 
on some individual in the family before trees were placed around, 
to become the abode of health after the change. A similar cheer- 
ing result would no doubt, manifest itself in all places of similar 
character, and especially around manvfaduring establishments, 
where the smell of " putrid waters " is quite as common as their 
rise and fall, at all seasons of the year. If these places, where 
hundreds and sometimes thousands, pursue their daily avocations, 
stood embowered in shady groves, whose limits extended far along 
the river side, the result in health as well as beauty, would in a 
few years, amply repay any expenditure necessary to secure the 
good effect. 
In towns, villages, and even large cities, the increased health of 
the population, arising from the effects of foliage in purifying the 
atmosphere, should furnish sufficient inducement to cause their 
general introduction to such places. Parks, densely wooded, 
should be increased, and streets be converted into beautiful ave- 
nues, by munipical or town authorities, at the public expense, as 
a means of securing health, where individual taste and enterprise 
fail to accomplish the object. 
But it is not merely as correctors of atmospheric effluvia, that 
the culture of trees commends itself to the consideration. They 
serve to equalize the temperature, in summer by their grateful and 
cooling shade, and in winter by breaking the voilence of the 
winds. Who has not often noticed when sitting in a park on a 
sultry August day, when not a breeze of sufficient power to waft 
the lighest feather, wooed him in open grounds, that gentle 
zephyrs, borne through the tree tops, came to fan his feverish 
pulse in his calm retreat? And who, as he has set in his em- 
bowered dwelling, at the noon tide of such a day, has not been 
fanned by kindly gales from his own dear trees that almost made 
him forget the sultriness of the "August noon?" 
In winter, when fierce storms are driven in wrathful fury from 
the cold, unsympathizing north, how gently they fall upon the 
dwelling, secured from their violence by the broad arms of the
