stubborn organic remains in the soil, 

 on the principle that putrescent sub- 

 stances hasten the process of putre- 

 faction in other organic bodies with 

 which they come in contact. Salt, in 

 a small proportion, has been demon- 

 strated by Sir J. Pringle to be gifted 

 with a similar septic property, and 

 that lime rapidly breaks down the tex- 

 ture of organized matters is well known. 



There is no doubt that rich soils, or 

 those abounding in animal and vege- 

 table remains, are less liable to change 

 in temperature with that of the incum- 

 bent atmosphere than those of a poorer 

 constitution. This partly arises from 

 the colour of the soils. Some manures, 

 as salt, protect plants from suffering by 

 sudden reductions of temperature, by 

 entering into their system ; stimulating 

 and rendering them more vigorous, 

 impregnating their sap, and, conse- 

 quently, rendering it less liable to be 

 congealed.

MARGINS of streams and other waters 

 must always accord with the pleasure- 

 grounds in which they are placed. Art, 

 therefore, must imitate each in its 

 proper place, not always by a studious 

 picturesque arrangement of the mar- 

 ginal accompaniments in each case, 

 but by excavating the groundwork, 

 planting the trees and shrubs, and 

 leaving the rest to the motion of the 

 waves of the water. After the effects 

 of one winter, stones or gravel may be 

 deposited in spots suitable for stony or 

 gravelly shores. 



MARGYRIOA'RPUS. (From margaron, 

 a pearl, and karpos, a seed-vessel ; re- 

 ferring to the pearly succulent fruit. 

 Nat. ord., Sanguisorbs [Sanguisorba- 

 cese]. Linn., %-Diandrla \-Monogynta. 

 Allied to Cliffortia.) 



Stove evergreen shrub. Cuttings of half- 

 ripened shoots, in April or May, in sand, under 

 a bell-glass, and in bottom-heat ; sandy peat, 

 with pieces of charcoal. Winter temp., 48 to 

 53 ; summer, 60 to 85.

 and anthos, a flower; dedicated to the 

 Virgin Mary. Nat. ord., Plttospornds

 1-Monoyynia. Allied to Sollya.) 



Greenhouse deciduous climbers. Cuttings of 

 young side-shoots, in sand, under a bell-glass, 

 in May ; sandy loam, fibry peat, with potsherds 

 and charcoal, to keep the soil rather open. 

 Winter temp., 40 to 45.

 the flowers, which last hardly a day. 

 Nat. ord., Irlds [Iridacece]. Linn., <\- 

 Trlandrla \-Monoqynia. Allied to Iris.) 



Marica has been long known, therefore we 

 retain it, but the true name is Cipura. Her- 

 baceous evergreens. By seed, sown in a slight 

 hotbed, in spring; by offsets, in abundance, 

 though seed ripens very freely; sandy loam, 

 peat and leaf-mould ; they require the protec- 

 tion of a greenhouse or a cold pit in winter.
