.hardened oil. Spider and limps are the chief 

 insrct pests ; they may be kept in check by timely 

 fumigation. 



Andi-eimus may be treated in similar fashion, 

 except that harder pruning is necessary to counter- 

 act its very straggling habit. Less water should 

 be given to this than to most of the other Cytisuses ; 

 very little- indeed is needed during the winter. It 

 does best if confined to small pots. 



Standard Cytisuses, worked on clean :>' or I' 

 stocks of the Laburnum, make handsome shrubbery 

 plants.

DABOECIA. 



A small genus of hardy evergreen shrubs (ard. 

 Kricacese). They are dwarf growing, and thrive 

 in peat in shady places. Propagation is by cuttings 

 and layers. 



Principal Species :

 Menziesia polifolia).

 flowers. 



There are several 'other forms varying little from 

 the type.

DACRYDIUM. 



A genus (ard. Conifcra) of greenhouse Conifers 

 ranging in height from If/ to 100'. They flourish 

 in a mixture of loam, peat, and sand, and may be 

 propagated from cuttings of young wood in verv 

 sandy peat beneath a bell-glass. The chief 

 economic value lies in the hardness of the wood of 

 I'ranklini, which is valuable for spars. Taxoides 

 yields a beverage resembling Spruce beer. 



Principal Species : 



araucaroides, 20'. elatum, 20'. 



cupressinum, 20'. Frankliui, iflO'. 



DACTYLIS. 



A strung-growing, hardy perennial Grass (ord. 

 Gramineae), often known as the Rough Cocksfoot 

 Glomerata flowers in June ami July, the spikes 

 being 'A' high. Propagation is by seeds and divi- 

 sion. It thrives in damp places. There is a 

 dwarfer form with variegated foliage, glomerata 

 variegata, that is extensively used in summer 

 bedding ; it has a light, silvery appearance. As 

 this is not so hardy as the wild form, some plants 

 should always be wintered in cold frames. 



DADDY LONG LEGS. 



One of our commonest summer insects is the 

 Crane Fly (Tipula oleracea), better known by its 

 popular name of Daddy Long Legs. This huge, 

 gnat-like insect, with six long, many-jointed legs, 

 and pair of gauze wings, is the parent of that most 

 vicious garden pest, the Leather Jacket giub. 



These grubs attack all the Cabbage family 



Lettuces, Beans, Potatoes, etc. consequently the 

 insects should be destroyed whenever found, to 

 prevent egg deposition. On grass or farm land 

 heavy rolling keeps the pest in check, but in 

 gardens trapping by means of sliced Carrots, 

 Potatoes, or Parsnips (each wit h a skewer attached) 

 buried just below the surface of the soil, is a good 

 remedy, provided the traps are regularly inspected 

 and the grubs killed. A weak solution of gas 

 liquor, with lime added, is said to be a ivmely: 

 this is applied through a watering-pot. The 

 Leather Jacket is occasionally confused with the 

 wireworm. (See WlKEWOBM.) 



D^EDALACANTHUS. 



Four species of this genus (ord. Acanthacese) 

 receive some attention from gardeners. They 

 require stove treatment, and are effective when 

 well grown. Propagation is by cuttings in very 

 sandy soil under a bell-glass over bottom heat, 

 early in the year ; also by seeds. Soil, mellow 

 loam, leaf mould, peat, and coarse sand.
