and will only need shading during the middle of the day if the house is 
properly ventilated. 
SEEDLINGS.—I have already referred to the various methods of sowing 
the seed, and will now endeavour to make a few remarks upon the subsequent 
treatment of the seedlings. Where seed was sown earlier in the year, it 
should now be showing signs of vitality, and forming: little green globules. 
‘These eventually become pointed, and in due time tiny roots are formed. 
At this stage they can be pricked off into what is known as store pots, but 
at one time thimble pots were employed, which were plunged in some 
moisture-holding material. Several seedlings are placed in the former and 
one in the latter. The last-named method has its advantages, as the 
‘seedling has a separate existence from the start, and it can be moved on 
when ready without disturbing other seedlings, but they occupy more space, 
and thus it is only practicable where small quantities are raised. 
PREPARATION OF STORE POTS.—These should be filled one-third of their 
depth with drainage, over which is placed a thin layer of the usual potting 
mixture. Whatever is used for the top layer it must be cut up rather fine, 
and a tolerably firm and even surface made. It may consist of a mixture 
of osmunda fibre, peat, and sphagnum moss, with a few partly-decayed leaves 
-or Belgian leaf soil, while many choose sphagnum alone. When preparing 
the latter it will be necessary to pick off the large heads, or the seedlings will 
-quickly be over-grown. The surface should be just. below the rim of the 
pot, and each must be given a thorough watering. After a few hours have 
lapsed they will be ready for the seedlings, providing the soil has become 
warm. A convenient distance between each seedling is a quarter of an 
inch, or less if very small, and when the operation is finished a light spray 
may be given to keep them in their positions. The receptacles in which 
the seed was sown can be returned to the raising case, if it contains any of 
‘the little green globules and sufficient has not been pricked off. 
SUBSEQUENT TREATMENT.— Where there is enough space the store pots 
-can be arranged in the seedling case for a few weeks, and failing this they 
should be placed near the glass in the warmest house. A moist atmosphere 
is necessary, and the pots must be sprayed over occasionally, while they 
should be protected from all strong sunlight. If the conditions are 
favourable the seedlings will soon increase in size, and in a few months be 
large enough to go three or four in-a thumb pot; but it is advisable to pot 
them off singly as soon as possible, then their individual requirements ca” 
be fully dealt with. 
ODONTOGLOSSUM AND OTHER COOL-GROWING SEEDLINGS.—Jhe 
procedure in regard to potting and soil is much the same as fot 
Caeyys &c., but a cooler house is needed. A.temperature of 55° ' 
‘60° F. is best for these plants, and they must. be carefully shaded at all
