THE PRACTICAL GARDENER. 



as in the formation of resting-places, much taste may be dis- 

 played, from the neat Doric bridge of polished stone to the 

 rude mountain-bridge of unhewn timber ; the one suited for 

 the dressed lawn, and the other for the wilderness or dingle. 



ARBORATUM. 



The arboratum is a division of the pleasure-gi'ound dedicated 

 to the cultivation of a collection of useful and ornamental trees. 

 It is to be regretted that so few specimens are to be met with 

 in this country of this extremely useful and interesting part of 

 gardening. Such however is the case, and we know not of 

 one complete collection in the country. The arboratum may 

 be situated in any convenient part of the pleasure-ground, if 

 large ; but if small, the distribution of the trees should be 

 blended through the lawn, shrubbery, and flower-garden ; and, 

 if planted with taste, will add much to the general beauty of 

 the whole. In their arrangement, some attention should be 

 paid to a particular mode of classification, so that at least all 

 the species of one genus may be brought together. The 

 fimilies which constitute the principal mass of this collection, 

 are —
