LITERATURE OF SCOTTISH ARBORICULTURE. 229 



of 2500 woodcuts, and the other four heing composed entirely of 

 octavo and quarto plates of reference. Some general idea may be 

 formed of the great labour and research undertaken by Loudon in 

 the preparation of this magnificent work, when it is stated that the 

 list of books of reference to which he had recourse in the preparation 

 of the Arboretum, and which he truthfully gives as showing his 

 different authorities, occupies no fewer than thirty-seven closely 

 printed and small-type pages of the first volume! 



Other important works upon arboricultural subjects, and filling con- 

 spicuous niches in its literature in the earlier years of the nineteenth 

 century might be named, such as the Hortus Kewensis, Miller's Dic- 

 tionary, in which are rendered, along with portraits of the plants 

 themselves, the names of their first introducers. The magnificent 

 " Salictum Woburnense," and the no less interesting treatises of Cook 

 and Hanbury, originally published contemporary with the earlier 

 editions of Evelyn's Sylva, were still regarded as authentic even about 

 the close of the eighteenth century. 



Coming down to more recent times, we find in 1842 the issue of 

 a book bearing the traces of careful study of trees and their manage- 

 ment, in Selby's " History of British Forest Trees." This work, 

 beautifully illustrated with steel engravings, is still an acquisition to 

 any library where the collection of works on trees is desired to be 

 complete. The monographs and critical notices of the various 

 species are well and carefully digested, and contain many interest- 

 ing particulars. The writer proceeds a good deal upon the style 

 and manner of Evelyn, but his facts are more modern, and the book 

 is more a handbook to the knowledge of the various trees than the 

 more elaborate work of Evelyn. 



In later years the attention of arboriculturists seems to have been 

 directed more particularly to specific branches of the science ; and, 

 indeed, as it became more a study, and the treatment of trees came to 

 be considered more with regard to the physiological laws of nature, 

 and in accordance with these, it is natural to suppose that such sub- 

 jects as pruning, transplanting, felling, draining, enclosing plantations, 

 and diseases of trees, &c, would form material for many different ex- 

 ponents, giving to the world their views in their own specific depart- 

 ment. Hence, we find such works as MTntosh on the Larch Disease,* 

 the Tree-Lifter by Colonel Greenwood,! Kbllar on the insects which
