SOU 



deep drills, twelve inches asunder. Thin 

 the plants to ten inches distance ; they 

 will grow freely, and their roots continue 

 increasing in size till September. The 

 roots may either remain in the ground 

 to be drawn as wanted, or taken wholly 

 up in autumn when their leaves decay 

 and preserved in sand all winter. 



To save Seed. Let some of the plants 

 remain where sown, when they will shoot 

 up in the spring, and produce plenty of 

 seed in autumn.

Greenhouse evergreen shrubs, from New Hol- 

 land. Cuttings of shoots, when getting a little 

 firm at the base ; sandy, fibry loam one part, and 

 two parts of sandy, fibry peat, with a little char 

 coal. Winter tenip., 40 to 48.

SCREEN. All cooling is occasioned 

 either by the heat being conducted from 

 a body by a colder, which is in contact 

 with it, or by radiating from the body 

 cooled, though circumstances accelerate 

 or retard the radiation ; and whatever 

 checks the radiation of heat from a body 

 is a screen, and keeps it warmer. For 

 screening or protecting the blossom of 

 wall-fruit, Mr. Errington states : We do 

 not know that any material is more pro- 

 per for covering than thin canvass, such 

 as is manufactured by Mr. Nathaniel 

 Hulme, of Paradise-green, Knutsford, 

 which he sells at about fivepence per 

 square yard. He generally makes it in 

 widths of three yards, which is enough 

 for most walls, so that every lineal yard 

 costs fifteenpence ; but then this can- 

 vass will last well for seven years if pro- 

 perly preserved, and a due care be exer- 

 cised. Thus it will be seen, that the 

 annual expense of protecting a lineal 

 yard of walling is not more than two- 

 pence-halfpenny, exclusive of a few ordi- 

 nary poles. We place a pole every six 

 feet, running tinder the coping at top, 

 and straddling away nearly two feet at 

 bottom. At two feet above the ground 



level an auger hole is bored in the pole, 

 and an oaken peg driven in, the end left 

 projecting nine inches forward ; and 

 when the canvass is lowered in the day, 

 it hangs in folds on this line of pegs: 

 this keeps it from contact with the damp 

 soil. Every pole has a ring dangling 

 from a staple close to the top ; and on 

 the outer face a rope of sash-cording is 

 attached to the edge of the canvass oppo- 

 site each ring ; this being passed through 

 the ring from the under side, enables the 

 operator to pull it up or let it down with 

 ease. Thus, when the canvass is low- 

 ered, the wall is uncovered, and vice versd. 

 Now, these rings and cords will add to 

 the expense ; and, since both are very 

 durable, we may, perhaps, add another 

 halfpenny per lineal yard to the amount, 

 accounting the ropes to last nearly as 

 long as the canvass. A still more com- 

 plete plan is to hang the canvass like 

 curtains, or after the manner of the 

 covering to what are termed conservative 

 walls. 



For wall-trees, now that glass is become 

 so much cheaper, the best of all screens 

 may be employed, viz., glazed frames, of 

 a length extending from the coping of 

 the wall to the surface of the soil, about 

 two feet from the stems of the trees. See 

 GLASS CASE. 



SCREW PINE. Panda'mis. 



SCREW-TREE. Heli'cteres. 



SCRUBBY OAK. Lophi'ra Africa'na. 



SCURVY GRASS (Cochlea' ria officina'Hs) 

 flourishes most in a sandy, moist soil. 

 Sow as soon as the seeds are ripe in June 

 or July, in drills, eight inches apart, and 

 half an inch deep. Thin to eight inches 

 asunder, and those removed may be 

 transplanted to abed at similar distances, 

 jiving water at the time, and frequently 

 ifterwards, until fully established. The 

 eaves are fit to gather during the follow- 

 ng spring. 



To obtain Seed. A few plants must be 

 eft ungathered from in the spring. They 

 svill run up to flower about May, and per- 

 'ect their seed in the course of the two 

 Allowing months. 



SCUTELLA'RIA. Skull-cap. (From scu- 

 tella, a little saucer; form of calyx. Nat. 

 rd., Lipworts [Lamiacese]. Linn., 14- 

 Didynamia 2-Anyiospermia.) 



Seeds and divisions in spring, and the evergreen 

 dnd> easily by cuttings under a hind-light; some 

 if the tender species are very harnu<,me, such as 

 'ordifo'lia; but the red spider must be looked 

 after.
