and impart a charm of no ordinary cha- 

 racter. 



It may therefore be said to those who 

 have not yet found a place for a collection 

 of ornamental grasses, that they are still 

 without some of the most useful, attractive, 

 and graceful of ornamental plants, whether 

 for the purpose of gathering for summer 

 and winter bouquets, or for imparting a 

 light and graceful appearance to the bor- 

 ders. 



That the plants may develop their true 

 characters, thin out sufficiently to afford 

 space for the growth of each, and this 

 should be done as soon as the plants can 

 be handled. All the varieties may be 

 gathered and dried for winter decoration.

Gratings. 



Generally, it will be desirable to con- 

 struct gratings and the sides of walks for 

 the removal of the surface-water ; in no 

 case, however, should these gratings com- 

 municate directly with the ,, 

 drains, as the sand soon 

 chokes them up. They 

 should consist of a well (c) 

 formed of brick, a foot or 18 

 inches square, and of suffi- 

 cient depth to leave a space 

 (B) of one foot or 18 inches 

 below the level of the 

 drain (A), for the deposition of sedi- 

 ment ; if this space be well cleared out 

 occasionally, the drains will work for 

 years without choking. 



Gravel Walks. 



Full instructions for the formation of 

 these will be found under Garden l^qths 

 and Walks : at present it is only 

 necessary to make some few remarks 

 upon their management. Few things are 

 more essential to a good garden than well- 

 kept gravel walks. Leaves and all ex-

traneous matter may be cleared away by 

 frequent sweeping. Weeds also may be re- 

 moved by hand-hoeing ; care at the same 

 time must be taken that the surface of the 

 walk is hard and level, and for this constant 

 rolling is desirable. When necessary, the 

 colour may be refreshed by turning, and 

 by the addition of a little fresh gravel ; 

 salt-and- water carefully used for destroying 

 weeds will at the same time much improve 

 the appearance of the gravel. 



Green-fly. 



Fumigate with tobacco the plant in- 

 fected, and syringe it well afterwards with 

 clean water, or, if it is not possible to 

 fumigate, wash the plant with strong 

 tobacco water by means of a soft brush. 



Greenhouse. 



Glass structures of even the smallest 

 kind would, a very few years ago, have 

 been considered a piece of great extrava- 

 gance for any but the affluent. But now, 

 on the contrary, there are few who would 

 consider the garden as complete without a 

 glazed house of some kind, however small, 

 or however plainly made it might be. For 

 any handy man who can use carpenter's tools 

 the construction will present no very great 

 difficulty, as maybe seen from the article that 

 immediately follows this. Putting up the 

 framework or skeleton, as it maybe called, 

 painting, glazing, fitting with shelves, and 

 even with a heating apparatus, and furnish- 

 ing with a suitable flooring, can all be 

 easily accomplished, and the result both 

 in appearance, and in the raising and 

 maintenance of flowers and seeds for 

 the garden that require protection at 

 the outset, will be satisfactory in many 

 respects. Technically speaking, the 

 greenhouse may be defined as a house 

 which is supplied with means of obtaining 

 artificial warmth therein. If there be no 

 heating apparatus it is known as a cool
