GRASSES for lawns and grass plots 

 must be varied according to the nature 

 of the soil, and we know of no more 

 judicious selections than the following, 

 recommended by Messrs. Lawson, of 

 Edinburgh 



Avcna flavescens (Yellowish 

 Oat Grass) 



Cynosurus cristatus 



(Crested Dog's Tail) .. 



Festucaduriuscula (Hardish 



Fescue) 3 3 4 



Fcstuca tenuifolia (Fine- 

 leaved Fescue) 2 2 I 



Lolium perenne tenue (Fine 



Rye Grass) 20 20 20 



Pou nemoralis (Wood Mea- 

 dow Grass) 14 \'i 2 



Poa nemoralis sempervirens 



(Evergreen Ditto) l 1^ 2 



Poa trivialis (Rough-stalked 



Meadow Grass) 14 lj 2 



Trifolium repens (White 



Clover) 777 



Trifolium minus (Smaller 



Yellow Clover) 2 2 1 



The above mixtures are enough for 

 an acre. Where the ground is over- 

 shadowed with trees, both the kinds of 

 Festiica should be omitted, and similar 

 quantities of the two kinds of Poa 

 nemoralis substituted. The best time 

 for sowing is early in the spring. 



GRASS-PLOT, correctly speaking, is a 

 parterre, or bed of flowers, arranged 

 with grass turf between them, instead 

 of gravel. It is usually confounded 

 with Lawn, which see. 



GRATI'OLA. Hedge Hyssop. (From 

 yracia, grace ; referring to its medicinal 

 virtues. Nat. ord., Fit/worts [Scrophu- 

 lariaceoe]. Linn., Q-Diandria \-Mono- 

 !f!/niti. Allied to Mimulus.) 



Hardy herbaceous plants. Division of the 

 plants in spring; rich moist soil. Latifolia 



and tetrugonn require the protection of a 

 frame in winter.

GRAVEL WALKS, like all other walks, 

 require a good substratum of drainage, 

 and the facing about five inches deep 

 of gravel. It must have no stones 

 mixed with it larger than good sized 

 marbles, and about one-fourth of it 

 must be much finer to nil the inter- 

 stices. Pit-gravel, with a slight admix- 

 ture of clay, and the more rubbly the 

 better, is the best for binding and form- 

 ing a solid walk. The more speedily 

 it is laid down after digging from the 

 pit, the more firmly will it bind. 



The following is an excellent plan to 

 make or turn gravel walks in dry wea- 

 ther. If of a sandy or gravelly nature, 

 strew a little clay or marl upon the 

 walk. When turned over, take away 

 the large stones and place them at the 

 bottom of the soil. Immediately after 

 you level your walk, apply your iron 

 roller steadily, and let a labourer follow 

 the roller, pouring upon it water regu- 

 larly as it passes over the ground ; in 

 twenty-four hours after, if the weather 

 is dry, it will be as solid as a stone- 

 floor. 



The best method of extirpating grass 

 from a gravel walk, is to spread salt iu 

 considerable quantities over its whole 

 surface; and if after the first applica- 

 tion it is found that portions of the 

 grass still exist, let another coating of 

 salt be applied, which will effectually 

 destroy it. Care must be taken, how- 

 ever, if the walk is edged with box, that 

 the salt does not come in contact with 

 it, otherwise it will destroy the edging 

 also. 



in the early part of April, gravel 

 walks are usually turned. After the
