and thoroughly damp down at least three times daily. The plants should now 
never be allowed to remain dry, but be well watered with soft water when- 
ever the compost shows dryness. A slight syringing overhead occasionally 
will also now be beneficial. Repot all species when necessary, aS soon as 
new growth commences, which may be any time from now until the 
autumn, Those not requiring it should be surfaced with fresh sphagnum 
moss. All of the small growing species such as Oncidium concolor, 
O. Forbesii, O. varicosum, Odontoglossum Rossii, O. Cervantesii, &c., are 
better suspended near the roof. 
The Cattleya and Mexican houses must likewise have no lack of 
attention. Here also damp down three times daily, ventilate carefully, and 
shade as required, remembering that Mexican house Orchids require but 
little shade. The syringe may also be employed beneficially, a gentle spray 
overhead at this season, once or twice a day in fine weather having an 
invigorating tendency, and greatly assists the plants to push quick clean 
growths. Remove the blinds as early in the afternoon as all danger of 
scalding from the sun is past, and at the same time reduce the amount of 
air, which will generate a warm, moist, and genial growing atmosphere, and 
infuse new life and vigour. Proceed with the necessary repotting as soon 
as the flowering is past. Such species as Cattleya labiata, C. Harrisoniana, 
C. guttata, C. granulosa and allies, which flower too late in the autumn 
to be then repotted, should also now be done. 
Barkerias are now starting to grow, and do best in baskets or on blocks, 
with sphagnum about the roots. They should be suspended in the Mexican 
house in full sunshine, where they will get a good current of air, and well 
syringed at least twice a day. Pleione lagenaria and P. maculata grow 
well in the same position if slightly shaded, and also enjoy the syringe. P. 
Wallichiana may be grown in a slightly cooler position, while P. Hookeriana 
and P. humilis succeed best in the Cool house. Thunias are now growing 
apace, and should likewise be near the glass in full sunlight in the same 
house, but kept somewhat on the dry side in order to ensure flowering. 
Exercise care when watering the deciduous Calanthes, as if waterlogged at 
this date they never recover. When better rooted more water may be 
given, and also a little liquid manure. Give them a light position in the 
warmest house, where the sun’s rays are broken by a thin shading. 
Cypripediums, Vandas, Saccolabiums, Renantheras, Phalznopses, 
Ancectochili, Angreecums, and Aérides will now delight in deluges of water 
at the roots. As soon as the sphagnum moss into which the plants are 
fixed—which should be fresh and in a growing state—shows the slightest 
signs of dryness by commencing to look white, it should receive a thorough 
drenching from a watering-can. It is superfluous to say that the 
aGnesES should also be kept well-saturated by frequent damping down. 
Growth will then proceed merrily, providing shading is employed during
