THE ORCHID REVIEW. 211 
CALENDAR OF OPERATIONS FOR JULY. 
By H. A. BURBERRY, Highbury, Moor Green, Birmingham. 
THE general management and treatment recommended for the month of 
May should still be continued, and it is unnecessary to repeat the details 
here. There may, of course, be instances where a slight departure from 
the general rule is advisable ; but this is a matter that must be left to the 
intelligence of the cultivator, who alone is in a position to judge of its 
desirability. To drawa hard and fast line, and follow it year by year, 
regardless of all changes—climatic and otherwise—is not what I should 
consider good practice. Theory is very good in its way, but it must go 
hand in hand with practice in order to secure the best results. Everyone 
is liable to have failures with some of his plants, before the road to success 
is found out ; and failures are our most efficient instructors. They incite 
us to further experiments, and these, coupled with careful observation of 
results, often lead to complete success. 
I have already in previous Calendars given general instructions on 
watering, damping down, ventilating, shading, &c., and think I have 
detailed the culture of all the more popular genera of Orchids; and it will 
therefore probably interest some of our readers if I say a few words upon 
the work that will most likely be going on here during the month of July. 
I believe professional men are generally charged with failing to enter into 
details, and this, at all events, I wish to avoid. 
THE CaTTLEYA HousE.—This house is damped down three times daily 
if bright and dry; twice if wet or cloudy. Air is admitted pretty freely, 
but the top ventilators are closed at night, unless the weather is very warm ; 
the bottom ones are closed more or less. The blinds are rolled down from 
about 9 a.m. to 4 p.m. on all bright days. If the weather is dull we do not 
keep the blinds down, but contrive to allow the plants as much sun as 
possible without scorching. For instance, when it is cloudy and sunny 
alternately, the blinds will probably be up the greater part of the day, only 
being let down when it is seen that the sun will be bright for a longer spell. 
Warmth in the pipes is only used when the nights are very cold. Cattleyas 
Mossiz, Mendelii, Schrodere, Skinneri, and probably Lelia purpurata, will 
be repotted or top-dressed before the end of the month. Cattleya labiata, 
being growing vigorously, will be given a good light position ; and C. 
Warscewiczii (gigas), likewise being growing strongly, will have the brightest 
part reserved for them. Léelio-cattleya X Arnoldiana is now in flower, 
and, like Lelia purpurata, one of its parents, will soon commence to make 
its new growth. Cypripedium niveum, C. concolor, C. bellatulum, and C. 
Godefroyz have been removed to a light shelf in this department, and ne 
showing evident signs that they appreciate it. The plants of Sobralia 
macrantha got too large for this house, and were turned out into the
