water from September till March ; and when the buds begin 

 to swell, water them, remove them to the coolest part of the 

 stove, and there let them begin to open their flowers, which 

 they may complete in the conservatory. While out of doors 

 they are best under a south wall or some sheltered situation, 

 where they may have all the sun : while there they will 

 rarely want any water except in long-continued dry weather. 

 Cuttings root so freely that if bits are left on the soil they 

 will strike into it from the sides ; they are, however, gene- 

 rally taken at the trimming time, and, after drying the cat 

 end, put in a pot, to be only removed as they want more 

 room. C. grandijlorus, the night-blooming Cereus, may be 

 treated in a similar way in all respects ; but until it gets 

 pretty old it seldom flowers. Continue growing and shifting 

 as it fills the pots, and when large enough let it remain till 

 it flowers. The stems are often trained up the wall of the 

 hothouse ; but the plants are better in the greenhouse at rest, 

 without water, from the time the year's growth is complete 

 to the time the buds swell, when they should be trimmed 

 back to the buds, and removed to a higher temperature ; or, 

 if they are trained on a wall, it ought to be in a conservatory, 

 not so cold as a greenhouse, nor so warm as a stove. The 

 creeping Cereus should be set on a shelf, or suspended, so that 

 its long flail-like shoots may hang downward : they flower 

 generally at the top, and, being altogether smaller, do not 

 require such large pots as the others. This sort does well in 

 the window of a living-room. The curious species may be 

 potted in moderate-sized, well-drained pots of loam and broken 

 crocks or old mortar, and require but little water, and seldom 

 to be shifted. All the Cereuses may be kept in a diy warm 

 greenhouse in winter, but do best when they have the warmth 

 of a stove during the gi'owing period.
