benefited by under-draining. Every 

 gardener knows the absolute necessity 

 for a good drainage under bis wall- 

 trees and vines, but few gardeners ever 

 think for a moment, whether there is 

 any escape and outfall for the water he 

 has drained from immediate contact 

 with the roots of the above-named fa- 

 voured trees. Every garden should 

 have drains cut, varying in depth from 

 two to three feet, according to the depth 

 of the soil, with an interval of twenty- 

 four feet between the drains ; twelve 

 feet will not be too near in clayey soils. 

 At the bottom of the drains should be 

 placed one -inch pipes ; these should be 

 well puddled over six inches deep with 

 clay, and then the earth returned. They 

 should have an outfall into a ditch, at 

 the least elevated side of the garden. 

 By having the pipes with a bore no 

 larger than an inch moles cannot creep 

 in; and that bore is large enough to 

 carry off all the water, after even the 

 heaviest rains. For full directions we 

 refer our readers to Donald's shilling 

 volume, entitled Land Drainage. 



DRAKE 'A. (Named in honour of 

 Miss Drake, botanical painter for the 

 Botanical Eegister. Nat. ord., Orchids 

 [Orchidacese]. Linn., 20-Gynandria 1- 

 Monandria. Allied to Caleya.) 



The only species is an extremely curious 

 ground orchid, having one flower on the top of 

 a slender stalk, eighteen inches long, "resem- 

 bling an insect suspended in the air, and moving 

 with every breeze." Greenhouse. Divisions; 

 peat, loam, and rough sand. 

 D. ela'stica (elastic). Variegated. September. 

 Swan River. 



DRAWN. A plant is said to be drawn 

 when it is unnaturally increased in 

 length. This is usually by an excess 

 of heat and moisture, and a deficiency 

 of air and light. 



DREPANOCA'RPUS. The Sickle-pod. 

 (From drepanon, sickle, and carpos, a 

 fruit ; referring to the shape of the 

 seed-vessel. Nat. ord., Leguminous 

 Plants [Fabacese]. Linn., \l-Diadel- 

 phia 4:-Dccandria.) 



Stove evergreen. Cuttings of young shoots 

 nearly ripe, with its leaves entire, in sand, 

 under a glass, and in bottom-heat ; peat and 

 loam, both fibry. Summer temp., 60to80; 

 winter, 50 to 55. 



D. luna'tva (httlf-monn capsuled), 12. White. 

 South America. 1792. 



DRESSING. Putting the borders in 

 order ; also manuring strawberries, as- 

 paragus, and other permanent beds. 



DRIF"T SAND is the sand washed by 

 floods into drifts or banks, whether by 

 the sides of roads or streams. 



DRILLING. Scarcely a crop in the 

 garden should be sown broadcast, for 

 drilling saves seed and labour ; and 

 although in some cases it takes more 

 time to insert the seed in drills, yet 

 this is more than compensated by the 

 time saved during the after-culture, for 

 the thinning and hoeing are greatly 

 facilitated. (See Broadcast.) 



The distance apart appropriate for 

 the drills for particular crops will be 

 found under their respective titles ; 

 they are usually made with a hoe and 

 line, but the drill-raJie is often used. 

 The teeth are set six inches apart, and 

 are broad and coiilter-formed. When 

 the drills are required to be less than 

 six inches apart the implement can be 

 worked diagonally ; but it may be made 

 with teeth moveable to any desired 

 space apart. 



Dm 'MIA. (From drimys, acrid ; re- 

 ferring to the juice of the bulbs. Nat. 

 ord., Lilyworts [Liliacese]. Linn., 6-

Little greenhouse bulbous plants from the 

 Cape of Good Hope ; elegant, though less showy 

 than the Ixias. Offsets; peat, or leaf-mould, 

 and sandy loam. Summer temp., 50 to "5; 

 winter, 35 to 45 ; potted when beginning to 

 grow, and until then kept dry after the wither-
