his farm, when he is clearing it ; a reserve which may 

 assure him, for the future, plenty of fuel, and timber for 

 building. To this I will add, that round the house a 

 shrubbery should be retained, and carefully cultiva,ted, 

 to afford shade and coolness, as well as to add to the 

 beauty of the surroundings of the abode. 



To give such advice to the settler, is to show others 

 the necessity and the advantage of setting out trees 

 round their houses and their appurtenances. Any pro- 

 perty, however mean ' its appearance when situated 

 on a naked spot, will, if situated in the midst of a pretty 

 grove, planted with taste and discernment, look com-

I will not treat this subject at length, as it might 

 seem to be unconnected with this work. Still, I must 

 bring forward one argument in favour of planting orna- 

 mental trees in towns and villages, and round single 

 houses. Trees, regarded from a sanitary point of view, 

 have a salutary effect. They prevent the land shaded by 

 their leaves from being too much heated by the sun, and 

 thus hinder the formation of a quantity of fetid gases, 

 whose emanations infect and vitiate the air of our towns 

 and larger villages. They retain, too, a healthy coolness 

 during the great heats of summer ; they preserve, in 

 some degree, the moisture of the air and soil, and afford 

 a shelter to the insectivorous song-birds, whose melody 

 delights us, and who deserve on every account all the 

 care which we can give them. 



I append a list of the forest-trees best suited to orna- 

 mental purposes, among them two or three -exotics 

 (foreigners) which are among the most useful for that 

 purpose, and the good qualities of which seem to adapt 

 them to our ends ; —
