If thefe Trees be covered with the Glaffes, it will contribute very much to forward their Blossoming; for tho' their Bloffoms will not be deftroyed by the Frofts, yet the more the Frofts come at them, they will both be the drier, and more hard to open.

If the Weather be tolerably mild, the Trees ought not to be hindered from the Benefit of the Showers till the Buds begin to ftir; but afterwards the Glaffes fhould be kept constantly over them till the Influence of the Sun is fomething confiderable.

But the Doors which are at each End of the Frame, fhould, in the mean time, be set open, when the Wind does not blow too fharp, and the Sun fhines any thing warm: and if this does not happen in the Space of a Fortnight, then the Doors at both Ends may be opened, and Mats of Bafs or Canvas should be hung up over the Door-ways, to correct the Winds, and give the Air leave to circulate in the Frames.

As for Cherries; about three Changes of Dung will be fufficient to bring them to a due Ripenefs in February, fuppofing each Parcel remains a Month at the Back of the Wall.

But as for Apricocks, Grapes, Nectarines, Peaches, and Plums, if April proves cold, the forcing Heat must be continued till May is fettled; but fome of the Glaffes fhould be opened in the Morning, in March and April, when the Wind is ftill, and the Sun warm; and they should be permitted to receive the Showers that fall, while the Fruit is growing; but while they are in Bloffom, no. Rain fhould come near them, because if there should be any Moifture lodged in the Bofom of the Flowers, and the Sun fhould fhine hot thro' the Glaffes, it would be apt to destroy them.

.

The Dung that comes from these Frames, having loft its Heat, may be laid in Heaps to rot for the meliorating of stubborn Grounds.

Another thing which ought to be obferved in planting Fruit in these Frames, is to plant thofe Fruits which come forward, together; and those which come late, by themfelves; because it will be prejudicial to the forward Fruit to give them any more Heat, when they have done bearing; when at the fame time the later Fruits fet amongst them may require more Heat, and to be continued longer; fome of them, perhaps, requiring an artificial Heat till May.

There may also a Row or two of fcarlet Strawberries be planted near to the Back of this Frame; and these you may expect will be ripe by the End of February, or Beginning of March.

As for the Vines; they may probably be brought to bloffom, and have ripe Grapes, in May.

There may also be here-and-there planted a monthly Rofe-tree, and Hyacinths, Jonquils, Narciffus's, Polyanthus's, and alfo early Tulips, might be planted in the Borders. RONDELETIA.

The Characters are;

It hath a falver-fhaped Flower, confifling of one Leaf, which is tubu lous, and refis on the Empalement ; which Empalement afterward becomes a roundish coronated Fruit, divided into two Cells, containing many small Seeds.

We know but one Species of this Plant; which is,

RONDELETIA arborefcens, tini facie. Plum. Nov. Gen. Tree-like Rondeletia, with the Face of Laurus Tinus.

This Plant was discovered by Father Plumier, in America, who gave it this Name in Honour to Gulielmus Rondeletius,

Rondeletius, a famous Phyfician of
Montpelier.

The Seeds of this Plant were fent to England by Mr. Robert Millar, Surgeon, who collected them on the North-fide of the Island of Jamaica, where the Trees grow plentifully, as alfo in feveral Parts of the Spanish Weft-Indies.

This Plant, being very tender, cannot be preserved in England, unlefs it is kept in a warm Stove. It is propagated by Seeds, which fhould be fown on an Hot-bed early in the Spring; and when the Plants are come up, they should be transplanted into separate small Pots, and plunged into a moderate Hot-bed of Tanners Bark, where they must be treated in the fame manner as hath been directed for the Pereskia; and in Winter must be placed in the Tan-bed in the Stove, where these Plants will I thrive, and in two or three Years will flower; when they will make an agreeable Variety amongst other tender Exotic Plants.

ROSA, The Rofe-tree.

The Characters are; The Flower is compofed of feveral = Leaves, which are placed circularly, and expand in a beautiful Order; whofe leafy Flower-cup afterward becomes a roundish or oblong fleshy Fruit, inclofing feveral angular hairy Seeds to which may be added, It is a weak pithy Shrub, for the most part befet with Prickles, and hath pinnated Leaves.

The firft Sort of Rose grows wild in the Hedges in moft Parts of England: the Fruit of this Tree is made into a Conferve for Medicinal Ufe; but this is feldom cultivated in Gardens.

The fecond, third, and fourth Sorts do alfo grow wild in divers Parts of England; and are rarely preferved in Gardens, unlefs for Variety-fake.

The fifth Sort is a Variety of the fourth, and is preserved by fome for the Beauty of its ftriped Leaves.

The fixth Sort is found wild in Scotland, and has been by many fuppofed to be the fame as the fourth Sort, but only differing therefrom in having variegated Flowers: which is a great Miftake; for I have obferved, where the two Sorts were

cultivated

cultivated on the fame Soil for many Years, and yet retained a confiderable Difference in the Size of the Plants, the Scotch Sort being not half fo large as the other; yet the Flowers were much larger, the Leaves were lefs, and the Branches much weaker, than those of the fourth Sort.

The last Sort here mentioned was raifed from the Seeds of the Scotch Rofe; and altho' the Flowers were plain-coloured, yet the whole Appearance of the Plant continues the fame as the original Kind, which is a plain Proof of its being different from the fourth Sort.

The Sweet-briar, although wild in fome Parts of England, yet is preferved in moft curious Gardens for the extreine Sweetness of its Leaves, which perfumes the circumambient Air in the Spring of the Year, especially after a Shower of Rain. The Flowers of this Sort, being fingle, are not valued; but the Branches of the Shrubs are cut to intermix with Flowers to place in Bafons to adorn Halls, Parlours, &c. in the Spring of the Year, the Scent of this Plant being agreeable to moft Perfons.

The double-flowered Sweet-briar is preserved on the Account of its beautiful Flowers, as well as for the Sweetness of its green Leaves.

All the other Sorts of Rofes are originally of foreign Growth, but are hardy enough to endure the Cold of our Climate in the open Air, and produce the most beautiful and fragrant Flowers of any Kind of Shrubs yet known. This, together with their long Continuance in Flower, has justly rendered them the most valuable of all the Sorts of flowering Shrubs; befides, the great Variety of different Sorts of Rofes will

make a Collection of Flowers, either for Bafons, or in the Garden, without any other additional Mixture; and their Scent, being the moft inoffenfive Sweet, is generally esteemed by most Persons.

But in order to continue thefe Beauties longer than they are naturally difpofed to laft, it is proper to plant fome of the monthly Rofes near a warm Wall, which will occafion their Budding at least three Weeks or a Month before thofe in the open Air; and if you give them the Help of a Glafs before them, it will bring their Flowers much forwarder, especially where Dung is placed to the Back-fide of the Wall (as is practifed in raifing early Fruits). By this Method I have feen fair Rofes of this Kind blown in February, and they may be brought much fooner, where People are curious this way.

You should alfo cut off the Tops of fuch Shoots, which have been produced the fame Spring, early in May, from fome of thefe Sorts of Rofes which are planted in the open Air, and upon a ftrong Soil: this will cause them to make new Shoots, which will flower late in Autumn; as will alfo the late removing the Plants in Spring, provided they do not fuffer by Drought, as I have feveral times experienced; but particularly in the Year 1718. when I had Occafion to remove a large Parcel of these Plants in May, juft as they were beginning to flower: in doing of which, I cut off all the Flower-buds, and after having opened a Trench in the Place where they were to be planted, I poured a large Quantity of Water, fo as to render the Ground like a Pap; then I took up the Plants, and placed them therein as foon as pof4C 4

fible,

sible, that their Roots might not dry; and after planting them, I watered the Ground well again, and covered the Surface over with Mulch, to prevent its drying; after this I repeated watering the Plants all over two or three times a Week, in the Evening, until they had taken Root in about three Weeks time, the Plants shot out again, and produced a great Quantity of Flowers in August and September, which were as fair as thofe produced in June. This is the only Sort of Rose for this Purpose, there being no other Sort which will flower both early and late, except this.

The next Sort of Rofe which flowers in the open Air, is the Cinamon, which is immediately followed by the Damask Rose; then the Blufh, and York, and Lancafter come; after which, the Provence Dutch hundred-leaved white, and most other Sorrs of Roses, follow; and the latest Sorts are the two Musk Rofes, which, if planted in a shady Situation, will feldom flower until September; and if the Autumn proves mild, will continue often till the Middle of October.

The Plants of thefe two Sorts fhould be placed against a Wall, Pale, or other Building, that their Branches may be fupported; other wife, they are fo flender and weak as to trail upon the Ground. These Plants fhould not be pruned until Spring, becaufe their Branches are fomewhat tender; fo that when they are cut in Winter, they often die after the Knife. These produce their Flowers at the Extremity of the fame Year's Shoots, in large Bunches; fo that their Branches muft not be shortened in the Summer, left hereby the Flowers fhould be cut off. Thefe Shrubs will grow to be eight

or nine Feet high, and must not be checked in their Growth, if you intend they should flower well, so that they should be placed where they may be allowed room.

The lowest Shrub of all the Sorts here mentioned, is the Scotch Rose, which rarely grows above two Feet high, fo that this must be placed among other Shrubs of the fame Growth. The red Rofe and the Rofa Mundi commonly grow from three to four Feet high, but seldom exceed that; but the Damask, Provence, and Frantfort Rofes grow to the Height of feven or eight Feet; fo that in planting them great Care should be taken, to place their feveral Kinds, according to their various Growths, amongst other Shrubs, that they may appear beautiful to the Eye.

The Francfort Rofe is of little Value, except for a Stock, to bud the more tender Sorts of Rofes upon; for the Flowers will feldom open fair, and have no Scent; but its being a vigorous Shooter, renders it proper for Stocks to bud the yellow and Auftrian Roses, which will render them ftronger than upon their own Stocks; but the yellow Rofes will feldom blow fair within eight or ten Miles of London, tho' in the Northern Parts of GreatBritain, they flower extremely well. This Sort muft have a Northern Expofure; for, if it is planted too warm, it will not flower.

All the Sorts of Roses may be propagated either from Suckers, Layers, or by budding them upon Stocks of other Sorts of Rofes; which latter Method is only practifed for fome peculiar Sorts, which do not grow very vigorous upon their own Stocks, and fend forth Suckers very fparingly; or, where
