talogue of the iftost 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 par- 
ticular pains which I have taken, not only to designate the neces- 
sary 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 pos- 
sible; 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 ad- 
vantageously conducted; it is hoped, that this will be found to be 
the most useful and valuable Gardener's Calendar hitherto pub- 
lished 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.
