already flowered. And there is another ornamental shrub, which 
will readily flower in the autumn, either by a late removal in the 
spring, or by pruning back in April or Maywe mean the 
Althea frutex ; which is a rare and pleasing sight in the fall of the 
year, when flowers are rather scarce. 
There are, doubtless, several other flowering shrubs which by 
art may be made more floriferous than they naturally are ; and 
even many of our most showy herbaceous flowers, as is well 
known, may be expedited in flowering by early sowing and pro¬ 
tection ; and many by pruning or cutting back may have their 
flowering and beauty prolonged. Even mignonette, candytuft, 
and other similar border-flowers, are rendered longer attractive 
by timely cutting-in. 
The above are only a few of the expedients to which the flower- 
gardener who aims at making the finest display on his beds and 
borders at all times may have recourse. And as it often happens 
that the owners of the best kept flower-gardens only see them 
occasionally, or at certain times in the year, the manager should 
study to have the finest show of flowers he can at the time of the 
owner s visits. An excellent flower-gardener of our acquaintance 
cuts off* almost all his finest border-flowers a month or six weeks 
before he expects the family to arrive, in order that a second 
bloom may come forth when most required. J. 
CHANGE OF AIR AND SOIL NECESSARY TO PLANTS. 
Flowering plants, as well as all those which are cultivated for 
their fruit, leaves, or tubers, become more vigorous and luxuriant 
when removed to a new place or country, than if kept in the 
country in which they have been raised. This circumstance has 
been so long observed by cultivators, that several rules of practice 
are founded upon it. A change of seed from the hill to the 
valley, and from the valley to the hill, is found profitable manage¬ 
ment. An exchange of seed between Kent and Northumberland 
is advantageous to the farmers of each respectively. The same result 
follows the exchange of bulbs or tubers. Foreign seeds, and all 
the different descriptions of roots, do better if imported and 
planted in this country, than if cultivated at home ; and the same 
is the case when English seeds, &c. are carried to the continent.
