as the curious sorts of hyacinths, tulips?, ranun- 

 cuhises, auernouts, carnations, and various 

 others, may be made either along the sides 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 gravellv cankerv 

 bottoms, proper drains should he formed 

 and conducted along the fronts of the borders, 

 to the full depth of the sub soils, in order 

 efTectually to convey off the injurious wetness 

 that mav take place, and allow of a suitable 

 bed beino' formed for the upper soil. This is 

 often done bv paving the bottoms of the beds 

 with tiles or bricks. But a much less expensive 

 and at the same time cft'ictual 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 w ith a laver 

 of good loam two inches in thickness, spread 

 evenly and well rolled down; then a similar 

 stratum of clean pit or river gravel applied o\er 

 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 down ; 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 w hole acquires a shining 

 hardness, and the gravel begins to show itself 

 clearly through the loamy coat. In this way it 

 is asserted a bottom mav 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 

 m descril)ing the culinre which they require. 



\A"here the raising and growth of most sorts 

 of culinary \egetables are the principal objects 

 of borders, there should be constantly a due 

 proportion of good vegetable mould in combi- 

 nation with a proper qtiantity of rich, mellow, 

 loamy earth, a suitable portion of well-rottetl 

 stable-dung, according to circumstances, being 

 incorporated with them, to produce crops in the 

 greatest ptrfeetion. 



Such borders as immediately bound or vcrsie 

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

 sides with edgings of some dwarf evergreen 

 sort of plants; such as those of boxj thrift, 

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



and most durable plant for this purpose. See 

 Buxus and Edging. 



These borders should alwavs be raised two or 

 three inches, or more, above the conmion 

 surface level, such as are detached being gene- 

 raliv finished off in a gently swelling or round- 

 ing form, in order that tliey may afftjrd the 

 fullest effect. 



BOSEA, a genus aR'ording a plant of the 

 shrubby exotic kind. The Slirubb\ Golden-rod. 



It belongs to the class and order Pentandria 

 D'lgyiiia, and ranks in the natural order of 

 Diiulelphia. 



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 five subulate 

 filaments, longer than the calvx: the anthers 

 are simple: the pistiliuiii is an ovate-oblong, 

 cuspidate germ : the style and the stigmas are 

 two: the pericarpium is 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 irregularlv, and make 

 considerable shoots in 5unnner, which should 

 be shortened every spring, to preserve the heads 

 of the plants in anv tolerable order: these 

 branches retain their leaves till towards the 

 spring, when they fall ofl", and new leaves are 

 produced soon after: the bark is reddish-brown, 

 andsniooth; 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 lurderneath, 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. 



Ciilliire. — The plants in this species may be 

 increased, bv plantmg cuttings of the young 

 shoots, in the early spring months, iii pc^ts of 

 light fresh mould, placed under glasses, or in a 

 moderate hot-bed, bv which their striking root 

 maybe much expedited. 



It is deposited in the green-house in assem- 

 blage with others of similar growl li. 



BOSOUfc-T, a term applied to detached 

 clumps, or other parts of gardens, pleasure- or 

 ornamented grounds, planted u itha variety of de- 

 ciduous and evergreen trees or i.hrubs, and herba- 

 ceous perennial flowers, eilherina 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
