A FEW HINTS ON THE MANAGEMENT OF TERRESTRIAL ORCHIDE^. 149 
other, with the exception of a few which should have rather a stronger heat than the 
others, as Acanthophippmm bicolor, Eulophia Guineensis, Peristeria elata, Phajus 
maculatiis, &c., which the remarks on the separate species in this paper will 
show. 
The best sort of soil is very sandy peat and leaf mould ; the former well broken 
to pieces, and the latter sifted, and the two well mixed together. 
All these terrestrial kinds require a season of rest, or a winter, like the 
epiphytes : the best season for this is from November to the end of March. But 
to this rule there are a few exceptions : the tops of some of the herbaceous kinds 
will die down at one time, and others at other times of the year ; and whenever 
that occurs, let such plants be placed in cooler situations, and receive little or no 
water until they begin again to grow. This period of rest will be their winter. 
The general season for potting is the beginning of April; but potting must be 
done at all seasons when the plants require it. 
In potting, always drain the pots well with broken potsherds, to carefully 
prevent any stagnation, which is generally fatal to all the tender kinds. 
Water regularly as often as the plants require it, except during the time of 
wintering, when they should be kept dry, or nearly so. 
The temperature of the stove species should not exceed 95 degrees, nor be 
lower than 7^ degrees by day ; or more than 70 degrees, or lower than 60 degrees 
by night during the time of their growth : but in the season of wintering never 
allow the heat to exceed 65 degrees, or be lower than 55 degrees either night or day. 
The Greenhouse kinds are very simple in their culture, merely requiring the 
same treatment as the stove kinds, except in the heat. 
The Frame kinds will, for the most part, grow freely planted out of doors, 
during the summer season, in the same way as the hardy kinds ; but they require 
sheltering in winter from the frost and wet. A system recommended by Mr. Stewart 
Murray, of the Glasgow Botanic Garden, and inserted in the London Horticultural 
Transactions, Vol. VI. answers well He " places a glass frame 9^ feet wide, 
2ifeet high at the back, 15 inches high in front, and of any length necessary, on 
a well-sheltered border, facing the south. The original soil within the frame is 
dug out to the depth of 16 inches, and the vacuum filled up with a mixture of one 
third leaf mould, one third turfy peat, one sixth spagnum or bog moss, and one 
sixth sand ; the whole is well broke and mixed together, but not sifted. The 
roots are then planted in this ; and care is taken that those kinds which require 
little moisture, are raised something above the level of the others. When planted 
water regularly, and shade when the sun is very hot ; and admit air to prevent 
the plants drawing. After they have done flowering, and the stems have died 
down, cut off the dead parts, and top-dress them with the compost as above." 
The hardy kinds will grow freely in the open air, in a well drained, warm 
situation. Early in the spring, when they are beginning to grow, shelter them a 
a little from the cutting winds which prevail at that season. The best situation 
for the border, is an eastern or north-eastern aspect : a southern aspect is too hot, 
unless the plants are partially shaded. It is also an advantage, if the border 
devoted to them be covered with moss, should the weather prove very dry.
