180 THE ORCHID REVIEW. 
certain amount of heat facilitates the process of drying in any case. Some 
flowers, however—such as Lycastes and other fleshy kinds—invariably go 
brown in drying, and we know of no method by which this change can be 
averted. The process is exceedingly simple, and the way in which the 
colours of many flowers—such as Odontoglossums, Oncidiums, and Den- 
drobiums—are preserved for a long period is remarkable. Two or three 
collections have been exhited at meetings of the Royal Horticultural Society 
within the last year or so, as was recorded in our pages at the time.

AN INTERESTING EXPERIMENT. 
Mr. T. L. Meap, of Oviedo, Florida, writes :—‘‘ I have just made arrange- 
ments to try a new experiment in Orchid seed culture. Many Orchids are 
rarely if ever found wild at less than 30 or 40 feet from the ground, even 
when other circumstances seem to favour them. So I have built a small 
platform in the top of a live oak, about 45 feet from the ground, and cons 
veniently accessible by ladders, where 1 propose to try—under varied 
conditions as to moisture and exposure—seeds of some thirty or forty 
different Orchid crosses, including pods from Vanda ccerulea and Cattleya 
citrina, which are thought difficult to manage under glass. It is said that 
resident Orchid amateurs in the city of Mexico find the adult plants to grow 
much better on the housetops than in the garden, with equal attention as § 
watering, so I have considerable hope of good results from the experiment. 
We shall hope to hear the results. It would be interesting to note the 
daily range of temperature in the two situations, and any other obvious 
differences which might suggest the cause of any variation in the results 
obtained.

CALENDAR OF OPERATIONS FOR JUNE. 
By H. A. BURBERRY, Highbury, Moor Green, Birmingham. 
THE temperatures given for last month should be maintained in all depart: 
ments, and the shading, airing, and damping down well attended to, which 
is a matter of great importance. 
On the Cattleya and Laelia houses, also the Dendrobium and other warm 
houses, the roller blinds should be removed rather early in the afternoon 
say from 3 to 5 o'clock, according to the aspect of the house—and at the 
same time the ventilation should be reduced and a thorough damping down 
given. Spraying the plants also overhead is beneficial. In fact, at this 
Season, when the weather is bright and hot, a good drenching overhea 
with soft warm water when the house is closed is often practised with very
