and soaked for two or three hours in a strong infusion of tobacco 
water, and then replanted in a fresh soil or compost, and removed to 
a situation at a distance from the former. But if the whole bed or 
border be overrun with this insect, it is best to take up all the plants, 
and having soaked them, to plant them elsewhere. The bed or bor- 
der should then be trenched up, and remain fallow to the next sea- 
son, or be planted with another crop not liable to this calamity. 
In their after management, they are said to blow at the same 
time, and require nearly the same treatment, as Auriculas, both with 
respect to soil and situation ; they are, however, more impatient of 
heat and drought, and more partial to shade and moisture. They 
may be set in the same sized pots, and in the same compost as the 
Auricula, only with the addition of more loam : or they may be 
planted on cool shady beds or borders, being very hardy, and seldom 
destroyed by the coldest and most severe season, because their parent 
is a native of this country ; but during the heats of summer they are 
frequently destroyed, unless proper precautions are taken. This dis- 
like of heat seems to indicate, that Polyanthus is rather an offspring of 
the Primrose, which requires shade, than of the Cowslip, which 
grows in open pastures ; though some seem to regard it as a variety 
of the latter. 
The roots of the wild plants, when they can be procured, may 
be taken up, divided, and planted out in the autumn, when they will 
flower in the following spring. The Auricula kinds may all be in- 
creased by seeds ; but in order to procure new varieties, choice should 
be made of the best flowers, which should be exposed to the open 
air, that they may have the benefit of the showers, with which they 
seldom produce good seeds. These ripen in June.
