Death of Mr. Loudon. 407 



mation of Gardens, in 1812 ; and three works on Hot-houses, in 1817 and 

 1818. In 1822 appeared the first edition of the Encyclopedia of Garden- 

 ing ; a work remarkable for the immense mass of useful matter which 

 it contained, and for the then unusual circumstance of a great quantity 

 of woodcuts being mingled with the text : this book obtained an extraor- 

 dinary sale, and fully established his fame as an author. Soon after 

 was published an anonymous work, written either partly or entirely by 

 Mr. Loudon, called the Greenhouse Companion ; and shortly afterwards 

 Observations on laying out Farms, in folio, with his name. In 1824, a se- 

 cond edition of the Encyclopedia of Gardening was published, with very 

 great alterations and improvements ; and the following year appeared 

 the first edition of the Encyclopedia of Agriculture. In 1826, the Garden- 

 er s Magazine was commenced, being the first periodical ever devoted 

 exclusively to horticultural subjects. The Magazine of Natural History, 

 also the first of its kind, was begun in 1828. Mr. Loudon was now oc- 

 cupied in the preparation of the Encyclopedia of Plants, which was pub- 

 lished early in 1829, and was speedily followed by the Hortus Britanni- 

 cus. In 1830, a second and nearly re-written edition of the Encyclope- 

 dia of Agriculture was published, and this was followed by an entirely re- 

 written edition of the Encyclopedia of Gardening, in 1831 ; and the 

 Encyclopedia of Cottage, Farm, and Villa Architecture, the first he pub- 

 lished on his own account, in 1832. This last work was one of the 

 most successful, because it was one of the most useful, he ever wrote, 

 and it is likely long to continue a standard book on the subjects of which 

 it treats. Mr. Loudon now began to prepare his great and ruinous 

 work, the Arboretum Britannicum, the anxieties attendant on which 

 were, undoubtedly, the primary cause of that decay of constitution 

 which terminated in his death. This was not, however, completed till 

 1838, and in the mean time he began the Architectural Magazine, the 

 first periodical devoted exclusively to architecture. The labour he un- 

 derwent at this time was almost incredible. He had four periodicals, 

 viz. the Gardener's, Natural History, and Architectural Magazines, and 

 the Arboretum Britannicum, which was published in monthly numbers, 

 going on at the same time ; and, to produce these at the proper times, 

 he literally worked night and day. Immediately on the conclusion of 

 the Arboretum Britannicum, he began the Suburban Gardener, which was 

 also published in 1838, as was the Hortus Lignosus Londinensis ; and in 

 1839 appeared his edition of Repton's Landscape- Gardening. In 1840, 

 he accepted the editorship of the Gardener s Gazette, which he retained 

 till November, 1841 ; and in 1842 he published his Encyclopedia of Trees 

 and Shrubs. In the same year he completed his Suburban Horticulturist ;
