88 THE ORCHID REVIEW. 
CALENDAR OF OPERATIONS FOR MARCH. 
By H. A. BuRBERRY, Highbury, Moor Green, Birmingham. 
TuE temperature for the month should range as follows :— 
Tue Coot Housr.—Day, with sun, 60° to 65°; without sun, 55° to 60°; 
night, 55°; morning, 50° to 55°. 
Tue INTERMEDIATE HousE.—Day, with sun, 70° to 75°; without sun, 
65° to 70°; night, 60° to 65°; morning, 58° to 60°. 
THE Warm Hovuse.—Day, with sun, 80° to 85°; without sun, 70° to 
75°; night, 65° to 70°; morning, 65°. 
The days are now lengthening and the light becoming stronger, there- 
fore we may gradually increase the supply of water at the roots without so 
much fear of bad results following. 
Ventilate freely on all suitable occasions, both night and day, more 
especially in the Cool departments. Beware, however, of the piercing east 
winds, which are panied ti by bright sunshine, running the 
thermometer up rapidly, and ofttimes prompting the cultivator to put 
on too much air. Rather than do this use the roller blinds, which should 
now be in position, and at the same time keep the ventilators closed. 
The season of growth is now at hand, and, with more solar warmth, the 
plants will soon begin to push out new roots and growth. When this is 
seen they may be re-potted or top-dressed. Increase the supply of moisture 
tmospherically by th ghly damping down twice daily, morning and 
evening. Repotting may now be said to have commenced in earnest ; on 
every hand are to be seen plants which require attention, and many others 
are hastening on to that goal, therefore it is necessary to be on the alert to 
keep pace with the times. 
The Anguloas, I see, are pushing forth new growth and flower buds, which 
appear simultaneously. If it is necessary to repot them this month is @ 
good time to do it, for if left until they have passed out of bloom the growth 
is far advanced, which renders repotting irksome and dangerous. These 
plants grow best in pots, and the compost should consist of two parts of 
good lumpy peat to one part of sphagnum moss. After repotting, the plants 
should be watered with care, enough being given to keep the compost just 
moist, until the roots have commenced to take hold, when they may - 
watered more freely, and given occasional doses of weak liquid manure until 
the pseudobulbs are matured, when they should be well rested throughout 
the winter in the coolest house, well up to the light. 
Thunias, too, should now be repotted. They are best grown in pots: 
about four strong bulbs to a 32-sized pot. As each bulb will have its old 
sel Removed entirely away, it will require to be made firm in its position 
by the aid of a stick thrust in the compost, which should be a mixture of
