Xlils should be given them by lowering the temperature or llio atmosphere in which they ore kept, and 

 withholding water from their roots giving only just enough moisture to keep them from shrivelling. Such 

 is the kind of treatment they ought to receive from October till the end of February. During thin time the 

 temperature should range from 53° to C0 ? by night, while in the daytime it may be allowed to rise a few 

 degrees higher by the aid of smn-hcat, which will not harm the plants. During the growing season, 

 which extends from March to the beginning of October, the temperature may be allowed to reach from 

 00° to 05° by night, and from 03* to 70* by (by; and after awhile it may be allowed to rise still higher — 

 from 65* to 75° by night, and from 70* to SO' by day, with sun-heat Kven a few degrees beyond these 

 limits will not be injurious, provided the plants arc shaded. The house will require to be kept moist 

 during the growing season by watering the pathways and walls morning and evening : but during the time 

 of rest it should be kept comparatively dry, only a Utile water being distributed about the tables and 

 pathways of the house on fine days, and even thb should be applied in the morning, so that it may be- 

 come partially dry again before the evening. If too large or too constant a supply of moisture is kept up 

 during the dull winter months the pseudobulbs or stems will be liable to rot. Caltlcyas do not at 

 any time require much water at the root. Kven during their rigorous growth they should only have just 

 sufficient to keep the soil moist. It must be remembered that for the most |>art these plants grow na- 

 turally with little or no covering to their roots, except the moss or leaves that may accumulate about them. 

 Of course, when grown in pots, they require less moisture than when grown on blocks of wood. 



The Gattteg* amethgttoglwm will succeed with block treatment; but pot-cultare, with peat soil, 

 is better suited for it. as it is a large-growing kind. The pot should, in potting, be filled half-Mi of pot- 

 sherds, and over these a layer of mo** to keep the drainage open; afterwards it should be filled up with 

 rough fibrous peat, broken to about the size of a ben's egg, and on this the plant is to be placed, so that 

 it may be two inches above the pot-rim. The plants must be firmly pegged to the peat, and the stems 

 carefully fastened to a stick, in order to keep them steady, which will facilitate their rooting. The peat 

 used for potting must be dry. and the finer parts should be taken away. When the peat is thus carefully 

 selected and prepared, the plants do not so often require potting.
