232 PARKS AND PLEASURE-GROUNDS. 



reference to tlie scientific principles on which its arrange- 

 ment is based. We trust the reader will not be repelled by 

 the terminology^ which it must be owned has a somewhat 

 formidable look, but which no one has ever imagined 

 could be materially simplified, and at the same time 

 retain its exactness. Even the unbotanical reader, by 

 running his eye along the English names, will be able 

 to form a pretty correct conception of the materials of 

 which an arboretum is composed. Persons about to un- 

 dertake the execution of such work will find in the fol- 

 lowing Synopsis the general outlines of an arrangement 

 which they may modify or abridge according to the 

 special objects they have in view. To those who may 

 think om- labour useless, we shall only say that we should 

 have considered a much slighter sketch a boon the first 

 time we were called to lay out an arboretum. 



As already stated, we prefer Dr. Lindley^s arrange- 

 ment of the Natural Orders, as most suited for the efifec- 

 tive adornment of an arboretum ; accordingly we have 

 borrowed the following syllabus of classification, with 

 some very slight modifications of the genera, from the 

 second edition of his ' Vegetable Kingdom.^ The reader 

 who desires fuller information regarding the alliances, 

 orders, and genera, will find it amply supplied in that 

 admirable work. Of course, in regard to the species, 

 he must have recourse to books containing detailed de- 

 scriptions, or to the larger catalogues which have been 

 published by Loudon and others. Loudon^s ' Arboretum 

 Britannicum'' and ' Encyclopaedia of Trees and Shrubs' 

 may also be consulted with advantage, or rather may 

 be regarded as means essential to success. We refer 

 throughout to his Natural Orders, exhibited in his ^ En- 

 cyclopsedia of Trees and Shrubs,' as affording detailed
