138 THE ORCHID REVIEW. [May, rg1o. 
potted a sunny position in a warm and humid house is given, and very 
little water is required until the growths are well away and the leaves begin 
to unfold, after which the supply should be increased. A light position 
should be chosen, with moderate shading from strong sunshine. When 
grown in this way from two to five strong spikes are obtained from each 
pot, and the plants can be very easily arranged for decorative purposes. 
Calanthe xX Bryan isa hybrid which was raised in the collection of the 
late Mr. N. C. Cookson from C. vestita and C. Regnieri, and thus is a form 
of C. X Darblayana which was raised by M. Ch. Maron a few years earlier. 
The flowers are white with a dark purple eye.

CALENDAR OF OPERATIONS FOR MAY. 
By W. C. Price, Oakdene, West Didsbury. 
THE plants in all departments are now growing freely, and every encourage- 
ment should be given to help them to grow briskly. The temperatures should 
be kept as nearly as possible to the figures given below whenever the 
atmospheric conditions are at all summer-like, but*if a cold spell should 
occur, which often happens during May, and even June, a few degrees 
lower is preferable to an excessive amount of fire-heat. 
TEMPERATURES, for the next four months, without sun-heat, should be 
as follows :— 
Cypripedium House: Day, 75° to 80°; night, 75°; morning, 70°. 
Cattleya House: Day, 70° to 75°; night, 70°: morning, 65°. 
Intermediate House: Day, 68° to 70°; night, 68°; morning, 63°. 
Odontoglossum House: Day, 60° to 65°; night, 60°; morning, 58°. 
SHADING.—Where lath blinds are used, it will be necessary to use a 
second shading during the hottest months of tne year, so as to avoid 
having any plants scalded by the sun, which can easily occur where the 
sun shines directly between the Jaths.. It does not require a thick shading, 
or one that remains dark on a dull day. There are numerous methods ot 
shading the glass, such as summer cloud, &c., but the method we use, and 
find very satisfactory, is as follows : Take two balls of whitening, half a pound 
of size, in powdered form, and one pint of linseed oil. Put one gallon ot 
water in a receptacle capable of holding about two gallons, and boil it; 
then reduce the whitening to a powder and stir in gradually, lastly adding 
the size and oil. The whole of the ingredients should be added while the 
water is boiling, and kept well stirred, being afterwards thinned down to 
requirements with cold water. If allowed to stand for a day or two, it 
should be boiled up again before using, as the oil floats to the top and 
cannot be mixed again without doing so. This mixture sticks well to the 
glass for the summer, but is no trouble to get off in the autumn when no 
longer required.
