of them. Cuttings of half-ripened shoots of C. alba, taken oflf in 

 spring, and inserted in a mixture of equal parts of silver-sand and 

 leaf-mould, firmly pressed in well-drained small pots or shallow pans, 

 supplied with a bottom-heat of 70°, and covered with bell-glasses, will, 

 if duly looked after in the way of shading from sunshine and supply- 

 ing them with water, emit roots in from four to six weeks, and be 

 ready for potting off into small pots in eight weeks from the time of 

 being put in as cuttings, C. alba is the strongest grower of any of 

 the species in cultivation, and being easier to propagate by cuttings 

 than the others, it is employed as a stock on which to graft the weaker- 

 growing kinds. In twelve months from the time the cuttings were 

 put in, they will be strong enough, if rightly treated during that time, 

 to receive the grafts of the sorts that it is desirable to increase. The 

 methods of grafting and subsequent treatment up to this time, when 

 the union of stock and scion is complete, are the same as those recom- 

 mended in the case of Azaleas in last month's issue of the ' Gardener.' 



Established plants should be repotted about the beginning of April, 

 and when doing so, drain the pots efficiently and carefully, making the 

 fresh compost moderately firm about the roots of the plants. Any 

 cutting back or pruning of the shoots that may be thought necessary 

 to keep the plants in shape, should be done at the same time. After 

 being repotted, place the plants in a position where they can have a 

 slight shade from sunshine, and where a temperature of from 60° to 

 70°, with plenty of atmospheric moisture, can be kept up. Let the 

 plants remain in this position till the end of May, and then remove 

 them to a cold pit or frame, plunging the pots in a bed of ashes, as 

 near to the glass as the size of the plants will permit. A slight shading 

 should be applied to the glass, and the pit or frame should be kept 

 rather close for a week or so after the plants are placed therein. Here 

 the plants may remain till the first week of September, when they will 

 be commencing to flower, and should be taken into the greenhouse 

 and have a position where they will receive as much light as possible. 

 Correas require to be carefully attended to with water at all seasons. 

 They are easily injured by over-watering, and stagnant water about 

 their roots kills them in a very short time. While the plants are in the 

 cold frame or pit, they will be benefited by an occasional application 

 of liquid manure ; the dose, however, must not be strong. As a rule, 

 the roots of hard-wooded plants are much easier injured by an over- 

 strong application of liquid manure than those of soft-wooded and 

 quicker-growing plants. 



Correas must also have due attention in keeping them free from 

 insects. Brown scale will attack them, and must not be allowed 

 to make headway on the plants. If permitted to do so, it is difficult 

 to get the plants clear of the pest again. Correas when in flower may 

 be employed as table-plants in the dwelling-house ; and for this pur- 

 pose, plants of the right size of C. brilliant and C. Harrisii are very
