CALENDAR OF OPERATIONS FOR SEPTEMBER. 
By H. A. Burperry, Highbury, Moor Green, Birmingham. 
THE temperature in all departments should now be reduced by a few 
degrees. Let the thermometer in the East Indian house during bright sunny 
weather range between 75° to 85°; in dull weather between 70° to 75° will 
suffice; at night, about 70°, and morning, about 65°. The temperature for 
the Intermediate, Cattleya, and Mexican houses should be 70° to 75° with 
sun; without sun, 65° to 70°; night, about 65°, and morning, about 60°. 
Of course the thermometer will often indicate a higher figure when exposed 
to the influence of the sun, but it will do no harm; on the contrary, pure 
sun-heat is at all times to be courted, and is most beneficial when properly 
tempered by the admittance of fresh air. 
Expose the plants to more light and sunshine by shading only when it 
is quite necessary to prevent scorching, and pay strict attention to the 
matter of ventilation. Both light and air are indispensable in order to well 
ripen the newly grown pseudobulbs. Twice a day will now be often enough 
to perform the operation of damping down if done thoroughly. 
The temperature for the cool house must still be kept as low as possible, 
both night and day. These plants particularly enjoy the cool, dewy night 
air, which must not on any account be excluded. Plants of Odontoglossum 
crispum and others which have recently flowered, and are again pushing 
new growth, should be repotted, if necessary, when the new growth is from 
one to two inches high. The old compost generally becomes exhausted 
after about two years. It is unwise to disturb these or, indeed, any other 
Orchids by repotting when the new growth is far advanced, and more
