Dibbling continued. 



represents the position of the Dibber for pressing the 

 soil against the roots; b, its position when this is com- 

 pleted ; and c, the Dibber removed, leaving the hole for 

 watering. The next illustration (d) shows a more careful 

 way of planting, on a email scale, by making a hole with 

 a Dibber, afterwards arranging the roots and filling in 

 by hand. A long Dibber is often used for planting Po- 

 tatoes; it is large enough to make a hole for the set 

 to drop in, and has a cross handle, for the use of both 

 hands, and a projecting piece of iron or wood which 

 serves the double purpose of forming a tread and in- 

 suring an equal depth to all the holes made. For 

 inserting cuttings or young plants, small tapering pieces 

 of wood are employed. 



DICENTKJL (from dit, twice, and ientron, a spur; in 

 allusion to the double-spurred flowers). STNS. Capnorchit 

 and Dielytra (often written Dielytra). OBD. Fuma- 

 riaceae. Very ornamental hardy herbaceous peren- 

 nials, with tuberous, horizontal, or fibrous roots. 

 Flowers pink or yellow, in terminal racemes ; petals 

 four, the two erterior ones equally spurred or gib- 

 bous at the base. Leaves stalked, multifid. They 

 are all of easy culture in moderately rich, light soiL 

 Increased readily by dividing the crowns, in early 

 spring; or by cutting the fleshy roots in short 

 lengths, and inserting them in sandy soil. D. spec- 

 tabdis is very beautiful when forced in early spring, 

 but the forcing must be very gentle, and the plants 

 kept as near the glass as possible. A moist tem- 

 perature of SOdeg. to 55deg. will be sufficient. As 

 a rule, it is much preferable to have fresh plants 

 every year, returning those which have flowered 

 under glass to the open border. The roots should 

 be placed in a compost of sandy loam, in well- 

 drained pots, as soon as the foliage dies off, and 

 transferred to a cold frame until introduced into 

 the house. After flowering, the plants should be 

 removed to a cold frame, to be shifted out in the 

 borders when severe frosts are past. Snoceesional 

 batches may be brought in as occasion requires, 

 and, with little trouble, the flowering period can be 

 prolonged from February to June. Plenty of water 

 is necessary when the plants are in full growth, 

 and occasional doses of liquid manure may be employed 

 with advantage.

 general cultivation. D. picta thrives in a warm part c
