is most difficult in a house containing plants of different natures and at ‘ 
different stages of their growth to give all fair treatment, and while we may s 
all know what is good practice, most of us know how difficult it is at times 
to put it into execution. To raise plants in sheath above the others will 
give them more airy surroundings, but the complete solution would be to | | 
place them together away from actively growing plants, so that they could 
be treated separately. If our summer was twice as long and more to be 
relied upon, we could give the plants longer to grow, and the optimum 
growing conditions would not have to enter so much into our calculations. 
PoTTING.—It has been to me something of a problem to know the best 
time to repot these Cattleya hybrids which flower during late summer. 
Root-action continues after the blooming period, although no new growth 
appears until next spring. It seems to me that those plants which flower 
up to the end of September should be repotted after flowering. These long- 
bulbed Cattleya hybrids grow very quickly. C. X Atalanta will start to 
grow in April, and show the sheath by the end of May. By the middle ~ 
-of June the sheath will be right up, although the leaves will grow and the | 
bulbs lengthen and thicken after that. To repot this plant in April would 
be manifestly unreasonable, as it would have to re-establish itself, make its 
growth, and flower, all within a period of, at the most, five months. If this 
plant be repotted on flowering and carefully watered, it will re-establish 
itself quickly, and the autumn-made roots will not get torn away from the 
pot at the very time that the plant has particular need of them. We do not 
like to see Cattleyas flowering and making a new pseudobulb at the same 
time, but it is not unusual in favoured localities for Cattleya Triane to 
make up a pseudobulb quickly in the beginning of the year and flower 
simultaneously with the one made normally the previous summer. I have 
seen Cattleya Mossiz flowering and showing the sheath in the growths for 
next year’s blooming. In a case of that kind one must wait until the bulb 
is finished and repot (if necessary, of course) when rooting from the finished 
bulb. This is better than disturbing the plant when right in the midst of 
its growth. C. Mossi# and the early-flowering species can safely be 
repotted when the flowering bulb for the next spring is completed in sheath 
if the next growth is too far advanced to be deemed safe for a shift when the 
plant has flowered. But I might say, inter alia, that this impulse to get Om : 
has not been a source of concern at Streatham. A fog which leaves 4 
deposit in your nose, and which makes your eyes smart—which coats the 
glass like pitch, and takes the leaves of the geraniums now and then during 
the winter, curbs any plantine frolic of this kind in the spring-flowering 
Cattleyas. 
COCHLIODAs.—Since the appearance in 1904 of Odontioda x 
Vuylstekez, Cochliodas have been very much in demand by raisers, ocCUPY”
