used. It is not advisable, nor necessary, to pot full- 
grown plants every year. Some may go for two or 
three years, but they must be assisted by weak liquid 
manure during the growing season. A little soot added 
to the manure water is found to benefit ferns greatly. 
Some of the ferns suitable for greenhouse culture are — 
Adiantum decorum. 
Asplenium bulbiferum. 
Asplenium caudatum. 
Blechnum latifolium. 
Davallia canariensis. 
Gleichenia dicarpa. 
Polypodium pectinatum. 
Pteris cretica. 
Pteris tremula. 
Woodwardia radicans. 
Chrysanthemums. — This is one of our most valuable 
classes of greenhouse plants. Though grown for a con- 
siderable time in the open air, yet they require the pro- 
tection of the greenhouse. They come into flower at a 
time of the year when most of the other plants have 
finished flowering for the season. 
They are propagated by cuttings, the young shoots 
which are produced from the root at the base of the 
stem being most suitable for this purpose. These may 
be taken when the plants have finished flowering. Short- 
jointed ones about 2 or 3 in. long should be chosen. 
After taking off the leaves at the base, and cutting them 
through with a sharp knife just below a joint, they should 
be inserted round the sides of small pots, which have been 
well drained and filled with a compost of sand and leaf 
mould in equal proportions. Four or five may be put 
into a 60s pot. The pots may then be placed in a cool 
propagating case or in a box covered with glass and 
paper to prevent undue loss of moisture until rooting has 
taken place. When they have rooted well, they may
