THE ORCHID REVIEW. 151 
of the old soil picked out, and re-placed with a mixture of two parts fibrous 
peat to one of fibrous loam, some chopped moss, and finely-broken crocks, 
the whole well mixed together. If any require new baskets or pans, they 
should be allowed to get dry for a few days, so that the task may be more 
easily. performed, with less risk to the roots, which will be much tougher 
when dry. In re-potting large specimens, pieces of crock should be placed 
here and there in the compost to obviate using so large a quantity of the 
latter. Careful watering should follow re-potting, but after the roots have 
taken hold of the new stuff large and frequent doses should be the rule, until 
the growths are complete, when smaller quantities, and less frequently 
applied, should be given. Red spider is very fond of the leaves of these two 
plants, and to keep these under frequent sponging is necessary. 
Cycnoches chlorochilon, ‘‘ The Swan Orchid,” requires to be grown in 
the hottest and lightest part of the stove, removed from any plants that are 
syringed, likewise Catasetums, for if water lodge in the unfolded leaves they 
are certain to damp off and ruin the growth. In the highly-saturated 
atmosphere of the stove these plants require very little water, though in 
settled, dry, hot weather a rather more liberal supply may be afforded. 
The different species of Mormodes require exactly the same treatment, but 
may be hung up at the warmest part of the Cattleya house, as a drier 
atmosphere is better suited to these. 
The concolor section of the genus Cypripedium is the most difficult to 
keep in good condition for long after being imported, and under ordinary 
circumstances one has to renew or replenish the stock whenever a chance 
of acquiring newly-imported plants occurs. Fortunately they are cheap ; 
but for all that it would be more creditable to us as growers if we could 
evolve and carry through a course of treatment that would be a permanent 
success. C. concolor, Godefroy, leucochilum, and niveum are all 
interesting, as well as pretty little plants, and given good attention, may be 
induced to thrive for a few years. 1 do not think it is so much a matter of 
compost with these, as some would have us believe, a suitable position and 
careful watering being the principal factors conducing to success. A hot, 
moist corner, where condensation does not take place through the 
temperature falling rapidly, is an ideal one to my way of thinking. In an 
atmosphere of this kind little water need be given to the plants direct, 
providing that the surroundings be kept well moistened. Almost 
innumerable composts have been advocated, but to my mind one cannot do 
better than to fall back upon our old friends, peat and moss, with ample 
drainage in the pots or pans used for the plants. C. bellatulum has a more 
robust constitution, though few manage it successfully for long. A fair 
amount of success may be obtained by placing newly-imported plants in well- 
drained pots or pans, and using for compost a mixture of one part fibrous
