THE ORCHID REVIEW. 155 



for repotting or top-dressing. Give little water to newly potted plants until 

 they have recovered from root disturbance, and their wants can be supplied 

 by occasional moistening of the surface, and with damping amongst the 

 receptacles. Cattleya and Lselio-cattlcya hybrids not in need of new 

 receptacles may have to be top-dressed, and should have the old material 

 removed and replaced with new, giving the whole a good watering when 

 finished. C. Warneri and Gaskelliana will have growth in a forward stage, 

 and may have water afforded more freely. They are both summer 

 flowering and very desirable additions to this family. The former should 

 after flowering be given a light airy position in this house, and be kept on the 

 ■dry side. C. Lawrenceana will have done blooming, and may now be kept 

 in a resting state for some time yet. When new growth commences, if 

 required, it may be repotted or otherwise renovated as its needs require. 

 Damping down the stages and floors will have to be done frequently, in 

 •order to secure a nice genial growing atmosphere, and air should be 

 given judiciously, in accordance with outside conditions. The shading 

 should be removed when possible, and the house closed early in the after- 

 noon, damping down when this is done. Little fire-heat will be necessary 

 during the day, except in dull weather, and sufficient only at night to 

 prevent the temperature from falling below 6o°. 



The Mexican House. — Most of the Lselia anceps will have commenced 

 new growth, and may now be freely syringed morning and afternoon, an 

 •operation they undoubtedly enjoy. On very hot days this can be done 

 frequently, and should be carried out until growth is nearly completed. 

 ■Give air in abundance, and shade during the hottest part of the day. 



The Cool House.— This house will have a very pleasing effect for some 

 time to come, what with Odontoglossums, Masdevallias, Epidendrum 

 Titellinum, Ada aurantiaca, Cattleya citrina, and a host of other beautiful 

 flowers which go to make such a grand display at this season. This house 

 will require to be kept well shaded for the next few months, which will aid 

 in keeping the atmosphere cool, and by judicious ventilating and damping 

 ■down tend to the promotion of free healthy growth. 



Vamda teres and V. HooKERiANAare both rather shy flowering species. 

 The former is now showing for flower, and when this is passed they should 

 be repotted. Secure each to a stick, place in boxes two-thirds filled with 

 drainage, and surface the whole with picked living sphagnum moss. When 

 finished they should be given a high position at the end of warmest 

 house. They require a strong moist heat, with plenty of sunshine when 

 growing, and a frequent application of the syringe. 



Dendrobiums. — Where a great many Dendrobiums are grown, a house 

 is usually set aside for them, and when this can be done it is very 

 advantageous. The majority will have been repotted or renovated as required
