CALENDAR OF OPERATIONS FOR SEPTEMBER.

ODONTOGLOssuMS.—This is the most important batch of Orchids that com- 
mands attention this month, and it is now that the general overhauling 
should take place. I have written before this year that some would be 
ready for potting during most months of the year, but it is now that the 
majority will be ready, and it is well to start at one end and carefully select 
any that require potting or surfacing. When this is done no plant is 
missed. There will be many that want some of the back portions removed, 
and when this is done they may be repotted into a smaller sized pot. It 
is always easy to pot a plant on. 
I have never seen the collection where there are not some plants that 
are not so good as they were last year, and such will be best suited if given 
a smaller receptacle. Then specimens are found where the leads have 
approached the rim of the pot and there are none centrewards, and when 
that is the case I prefer taking it carefully apart, cutting away all the old 
bulbs, and remaking the specimens, rather than potting it on to give the 
leads room to develop. Others may have made grand bulbs, the compost 
being still in a sound state, yet without room for further development. 
Such will be best suited by only having the roots liberated a little, the 
surface material removed, and a slightly larger pot given. All must be 
treated individually, for what is right for one may be wrong for the next. 
Such a great deal depends on the constitution of the plant. 
At this potting there is sure to be a good number of back bulbs cut off, 
and if the variety is of sufficient merit to make it desirable to increase the 
stock, these back bulbs should be suspended in a warm, dry, and light 
shed, just the reverse of their growin 
soon they will emit a new lead, and as soon as the growth is visible pot it 
up and place them with the others in their own house. I have found 
quicker results from this method than when we laid them on the stage 
under the plants, and certainly we have had a larger percentage come away- 
For compost, &c., I would refer to the Cal

y of these, when well grown, are very decorative, 
ting, and although they, like many other varieties, 
ular of late, there is every reason to believe they 
will again be extensively grown. The present season is a most suitable one 
for giving the plants a thorough overhauling, potting those that require it, 
and surfacing others that are in a sound State, using a compost of good 
fibrous peat and sphagnum in equal parts, with plenty of coarse sand and small 
crocks. Ordinary pots are quite suitable for such as can be accommodated 
in One not more than seven inches in diameter, but larger plants will look 
§ quarters, and given no water. Very
