PREFACE. v jj 



cultivation of Liquorice, Rhubarb, Dyer's Madder, Weld or 

 Dyer's Weed, Fuller's Teasel, Sea Kale (Crambe muritima), 

 Cork-tree, Manna, Ash, Tanner's Sumack {Rhus Coriaria), 

 Paper Mulberry, Mulberry-trees for feeding Silk-worms, (and 

 care of the insects,) with every other plant, not already common, 

 which appeared to me of sufficient importance, either in a 

 commercial, manufacturing, or ornamental point of view, or as 

 affording any of the luxuries or necessaries of life, have been 

 treated of with due attention: and in order to accommodate the 

 Agriculturist, I have given a classical catalogue of the most 

 important and valuable grasses and other plants used in rural 

 economy; and likewise pointed out the particular kind of soil, 

 in which each plant cultivated as a grass, or exclusively on 

 account of its foliage, has been found, upon repeated trials, to 

 succeed best. 



From an experience which I have had of near thirty years 

 in practical gardening, on a general and extensive scale; 

 the particular pains which I have taken, not only to designate 

 the necessary work of every month, but also the best methods 

 of performing it; the avoiding of all unnecessary repetitions, 

 so frequent in works of the kind, in order to render it as full 

 of important matter as possible; the assiduous endeavours to 

 make it useful in every state of the Union, and to induce an 

 association of the science of Botany with practical horticulture, 

 without which the latter can never be so advantageously con- 

 ducted; it is hoped that this will be found to be the most useful 

 and valuable Gardener's Calendar hitherto published in 

 any country, but more particularly so to the citizens of the 

 United States, for whose use it has been written, and to whom 

 it is respectfully inscribed by the Author.
