Progress of Horticulture for 1847. 9 



The Paiilownia, the Deodar cedar, the cedar of Lebanon, the 

 Liicombe oak, the Araucaria imbricata, and other equally 

 fine trees, are now prominent articles in the catalogues of every 

 extensive nursery establishment. Each of them have stood 

 the winter as far north as the latitude of New York, and all 

 have been tried, except the Araucaria, in that of Boston, and 

 found perfectly hardy. The latter, we hope to make a trial 

 of another winter, when the plants are stronger. Nothing 

 will add more to the beauty of a place than a good variety of 

 the finer Coniferae, such as the above kinds, the true Silver Fir, 

 Norway Spruce, Siberian Arbor Vitae, &c. 



The weeping trees, and smaller ornamental trees, grafted 

 as standards, are also fine objects for lawns, or for situations 

 where they will form prominent features of the landscape. 

 The weeping elm, beech, lime, mountain ash, oak, hornbeam, 

 ash, &c., are of the former class, and the amelanchiers, pru- 

 nuses, cratseguses, sorbuses, lilacs, &c., of the latter. 



The only thing now wanting to introduce more speedily all 

 the finer ornamental trees into general cultivation, is the 

 establishment of arboretums, or, if not arboretums, according 

 to the construction of the late Mr. Loudon, plantations of 

 specimen trees, where the habit of growth, peculiarity of foli- 

 age, general aspect, and all other characteristics, can be dis- 

 tinctly seen by the purchaser. Some definite idea can then 

 be formed of each and every tree, and their desirableness for 

 the purposes of ornamental landscape. This plan has been 

 adopted by all the leading commercial gardens of Britain, and 

 the consequence has been an immensely greater demand for 

 trees of every description. Those who rely upon the nursery 

 row to show ofi" their stock, will be left behind, and their limited 

 sales will be the best evidence of their want of industry and 

 intelligence, in keeping up with the advancing spirit of arbor- 

 icultural improvement. 



The great pertinacity with which our people adhere to one 

 thing cannot be better exemplified, than in the general desire 

 to plant elm trees in preference to all others. We certainly 

 shall not deny the magnificence of a fully grown elm ; but 

 yet we would by no means plant it in front of every dwelling : 

 there are several other trees which are equally as well, and, in 

 many instances, where the house is near to the street, much
