you to liavc the mould severely frozen in the 
pots, as by the end of the bloom, 1 
expect, is formed, although very low in the 
heart of the plant, and to get them severely 
frozen, would be risking too much with those 
choice sorts you intend to exhibit for a prize, 
or even to keep for your own amusement 5 
for if the mould in the pots be very wet at this 
season, the severe frost takes more ea.sy hold 
of it, and is one cause why they should be kept 
dry ; and if severely frozen it tends to injure 
the bloom in the spring ; but if there is likely 
to be a continuation of frosty weatlicr, and the 
plants have been close shut down for three 
weeks (it may now be the 18th day of January) 
if so, I should recommend the snow to be taken 
off the mats (if any) and the lights taken off 
for a few hours only in the day, or give plenty 
of air behind, as a little light and free air will 
greatly refresh them ; if the sun should break 
out for two liours, by all means let them en- 
joy it — it will nourish them at this cold season 
of the year — as consider they very likely have 
been closely shut down for more than three 
weeks, .and are in absolute want of a little 
atinosphei'ic air. Although the weather is 
sharp and frosty, a little fresh air wdll not by 
any means injure your plants ; in fact it freezes
