induces canker, and a host of other evils most pernicious in their 
effects through the winter. Should the plants appear to require a 
greater supply of food than can be given while in small pots, by 
flagging soon after they are watered, it is far better to shift them 
into larger, than to feed them with pans; in fact, they should be 
so circumstanced as not to require very frequent applications of 
water, which implies plenty of root room, and when water is 
given let it be in sufficient quantity to thoroughly moisten all the 
earth in the pot, rather than by the little-and-often system, which, 
from its uncertain action, is entirely condemned by all good 
cultivators; for, by following it strictly, the surface of the soil will 
present a sodden appearance, from its repeated wettings, while 
from the inadequate quantity given, the bottom of the pot will 
remain quite dry, and thus two opposed actions are going on, the 
collar of the plant is surrounded by moisture while its roots are 
dry, a more fatal position it would be difficult to suppose ; nor is 
this objection confined to the Primula, for it equally affects all 
other plants grown in pots. 
In the foregoing remarks I have abstained from enlargement 
on the ordinary management of the species, believing it to be so 
generally understood as to need no mention, and if the difference 
I have pointed out appears but small, it must be remembered it 
is of just that nature, applied at the period of the plants’ most 
active progress, to have the greatest possible effect, and should 
the hint prove serviceable to any one, the object will be obtained 
for which I wrote.

TEMPERATURE IN CONNEXION WITH HORTICULTURE. 
There is perhaps no agent in the growth of plants of greater 
power, or that should be more thoroughly under the command of 
the cultivator, than this; its effects are almost immediate, and 
according as its presence is more or less proportionate to the 
requirements of the plants, so will they luxuriate or die. As we 
are just now arriving at the most active period of vegetable ex¬ 
istence, when the influence of temperature is likely to be deve¬ 
loped to the fullest extent, and when any mistake in its
