BOS 



as the curioussorts of hyacinths, tulips, ranun- 

 culuses, anemones, carnations, and various 

 others, may be made either along the bides of 

 walks, or detached in other parts of gardens or 

 ornamented grounds. 



Where the situations in which the borders 

 are made are of the more moist retentive 

 kinds, having clayey or gravelly cankery 

 bottoms, proper drains .should be formed 

 and conducted ajpng the fronts of the borders, 

 to the full depth of the sub soils, in order 

 effectually to convey oil' the injurious wetness 

 that may take place, and allow of a suitable 

 bed being formed for tile upper soil. This is 

 often done by paving the bottoms of the beds 

 with tiles or bricks. But a much less expensive 

 and at the same time effectual method is ad- 

 vised by the author of the " Scotch Forcing Gar- 

 dener," which is that of letting the bottoms belaid 

 in a sloping manner from the walls to the drains, 

 a fall of six inches being given, first with a layer 

 of good loam two inches in thickness, spread 

 evenly and well rolled down; then a similar 

 stratum of clean pit or river gravel applied over 

 it, and forced down in the same manner : upon 

 this another coat of loamy earth is to be depo- 

 sited to the thickness of an inch or more, and 

 well pressed :!own ; the whole being executed 

 while the materials are in a rather dry condition ; 

 the whole being afterwards a little moistened 

 and well rolled down till the surface becomes 

 glazed, the waterings and rollings being con- 

 tinued alternately till the whole acquires a shining 

 hardness, and the gravel begins to show itself 

 clearly through the loamy coat. In this way it 

 is asserted a bottom may be formed, through 

 which the roots of no trees can penetrate, and 

 which is, at the same time, perfectly favourable 

 to the growth of trees and plants. 



In constituting the borders, those substances 

 and mixtures of different materials which are 

 most adapted to the growth and success of par- 

 ticular sorts of trees or plants, will be explained 

 in describing the culture which they require. 



Where the raising and growth of most sorts 

 of culinary vegetables are the principal objects 

 of borders, there should be constantly a due 

 proportion of good vegetable mould in combi- 

 nation with a proper quantity of rich, mellow, 

 loamy earth, a suitable portion of well-rotted 

 stable-dung, according to circumstances, being 

 mcoiporated with them, to produce crops in the 

 greatest perfection. 



Such borders as immediately bound or verge 

 gravel- or sand-walks, should be planted on the 

 sides with edgings of some dwarf evergreen 

 sort of plants; such as those of box, thrift, 

 daisies, pinks, &c. but the first is the neatest 



and most durable plant for this purpose. See 

 Buxus and Edging. 



These borders should always be raised two or 

 three inches, or more, above the common 

 surface level, such as are detached being gene- 

 rally tinished off in a gently swelling or round- 

 ing' form, in order that they may afford the 

 fullest effect. 



BOSEA, a genus affording a plant of the 

 shrubby exotic kind. The Shrubby Golden-rod. 



It belongs to the class and order Pentmulria 

 Digi/i/ii/, and ranks in the natural order of 

 Dhidelph'ia. 



The characters are: that the calyx is a five- 

 leaved, equal perianthium: leaflets roundish, con- 

 cave, and erect, thinner at the edge: there is 

 no corolla: the stamina consist of live subulate 

 filaments, longer than the calyx: the anthers 

 are simple: the pistillum is an ovate-oblong, 

 cuspidate germ : the style and the stigmas are 

 two : the pericarpium i3 a globular, one-celled 

 berry; one seed, round and acuminate. 



The only species is the B. Yervamora, Golden- 

 rod Tree. 



This is a rather strong woody shrub, with a 

 stem as large as a middling person's leg; the 

 branches come out very irregularly, and make 

 considerable shoots in summer, which should 

 be shortened every spring, to preserve the heads 

 of the plants in any tolerable order: these 

 branches retain their leaves till towards the 

 spring, when they fall off, and new leaves are 

 produced soon after: the bark is reddish-brown, 

 and smooth; the wood being white: the leaves 

 are two inches long, and one and a half broad, 

 roundish, broader at the base, blunt at the end, 

 and white underneath, resting on short petioles: 

 the ribs purple. The flowers come out of the 

 ends of the twigs, on alternate pedicels, at the 

 base of which is a stipule : the calyx is purplish, 

 and six-leaved: the seed of a black colour. 



It is a native of the Canary islands. 



Culture. — The plants in this species may be 

 increased, by planting cuttings of the young 

 shoots, in the early spring months, in pots of 

 light fresh mould, placed under glasses, or in a 

 moderate hot-bed, by which their striking root 

 maybe much expedited. 



It is deposited in the green-house in assem- 

 blage with others of similar growth. 



BOSQUET, a term applied to detached 

 clumps, or other parts of gardens, pleasure- or 

 ornamented grounds, planted with a variety of de- 

 ciduous and evergreen trees or shrubs, and herba- 

 ceous perennial flowers, citherin a regularor irre- 

 gular manner. They should be laid out in forms 

 suited to the nature, extent, and particular 

 circumstances of the ground, so as to produce
