THE ORCHID REVIEW. 83 
conceded to the wishes of the Orchid Committee in having paintings made 
of the plants certified, which have now become a very valuable record in the 
past four years, but then the Committee has paid half their cost to procure 
records whereon to base their judgment for the future in their voluntary 
- Jabours. No one can over-estimate the use of this proceeding, and a Society 
which could afford to paint all new and worthy forms of species or new 
hybrids, whether certified or not, would amass the grandest record of Orchids 
ever got together. Individuals can doa great deal, but a Society can do 
far more, when it is properly managed, and perfect records could then be 
made. “ Argus ” once expressed a wish for a list of Odontoglossum crispum 
varieties. Has any complete list ever been compiled that any grower could 
purchase? No! And why not? How many hundreds of thousands of cris- 
pums are there now in cultivation, and yet there is no complete authentic 
information regarding them that he or I can consult to see if our newly 
bloomed prodigy is like any of its predecessors. If there is any ‘“‘go” in 
the Orchid growing fraternity, let us try to make a Central Institution, and 
the sooner we begin the better, or this century will be where the last one is, 
(before we or our great grandchildren have one)—gone !

CALENDAR OF OPERATIONS FOR MARCH.

Now that the season of growth is rapidly advancing, the temperatures 
should be all owed a rise of a few degrees in all departments. The following 
figures will be a very good guide :— 
Coot Housr.—Day, 60° ; night, 50° to 55°: 
INTERMEDIATE HovusE.—Day, 65°; night, 55° to 60°. 
East Inpian HousE.—Day, 70°; night, 60° to 65°. 
The atmospheric conditions should quite naturally follow the temper- 
atures, and gradually become more exciting and favourable to free 
and healthy new growth. Damping down of the paths, stages, and walls 
may now quite safely take place two or more times a day in accordance 
with the amount of fire heat required. Still exercise great care mm the 
Matter of ventilation. The cold winds at this season are very searching, 
and rather than have the ventilators opened too wide it would be far safer 
hot to open them at all unless the weather is mild. 
The sun is now gaining a good deal of power, and during clear days will be 
Sufficient to warm up the houses without the aid of fire heat. Sometimes, 
however, the sun pops out unexpectedly when the pipes have already been 
Warm enough to maintain the required temperature. In such a case the houses
