it is a ditch or river, the water is carried off the place, otherwise a 

 small pond may be formed in the grounds and made ornamental 

 (see Flower Garden Water plants). The trenches for the pipes 



may be 30 ins. deep and 15 ft. 

 apart in stiff soil, 3 ft. deep and 20 

 ft. apart in lighter ground. Two- 

 inch earthenware drain-pipes 12 

 ins. long are suitable, and the cost 

 is about 30 shillings per 1000; the 

 ends may be left open. Care must 

 be taken that the bed of the trench 

 is perfectly firm <nd level. The 

 pipes may be laid in diagonal lines 

 leading to the main drain. With 



HOW TO DRAIN LAND. a P r per fall and outlet, water 



Diagonal pipes 15 to 20 ft. apart, leading cannot lie near the surface in 

 to a drain-pipe which discharges in a ground thus treated. Flower-pots 

 ditch. are provided with a bottom-hole 



in order to allow superfluous water 



to escape, but in the absence of drainage material the soil would 

 fall through. By laying crocks (broken flower-pot) over the hole 

 the soil is upheld, but water is allowed to escape. It is best to 

 choose one large piece for the bottom layer, and place it concave 

 side downward, then cover with smaller bits arranged so as to over- 

 lap. With a little clean moss or a few flaky portions of compost 

 over all perfect drainage is provided, but a few pieces of charcoal 

 are an improvement. Pots for Orchids are filled two-thirds full of 

 drainage, to allow for the large quantities of water needed. 



Drosera, Sundew (dros-era, from droseros, dewy. Ord. Drose- 

 raceae). Interesting insectivorous plants. D. rotundifolia is a 

 British plant, covered with glandular hairs that sparkle with 

 moisture. It likes a cool, moist spot, with peaty soil. Propaga- 

 tion is by division. Binata and filiformis are pretty exotic species. 

 All may be grown in pots for the greenhouse if desired, peat with a 

 surfacing of Sphagnum moss being used. 



Dryas (dry-as, from dryades, wood-nymph, referring to the Oak- 

 like leaves. Ord. Rosaceae). The best-known species is octopetala, 

 which is a British evergreen shrub, and has white flowers in early 

 summer. A trailer, it is suitable for the rockery. It thrives in 

 loam, peat, and sand, and may b;i propagated by division in spring. 

 Dutchman's Pipe, Aristolochia sipho. 

 Dyer's Green Weed, Genista tinctoria. 



Earwig. When present in large numbers the earwig is a great 

 trial to gardeners, attacking both plants and flowers. Traps of hay 

 in small flower pots inverted on stakes should be set. 



Eccremocarpus (eccremocar-pus, from ekkremes, pendent, and 

 karpos, fruit. Ord. Bignoniaceae) . The only popular species, 

 scaber, is much esteemed as a trailer, both indoors and out. It 

 produces orange flowers freely in July. It may be treated as a 

 half-hardy annual (see Annuals). It is illustrated in the Botanical 

 Magazine, t. 6408 (syn. Calampelis scaber).
