have fmall front windows to this flove, to admit air by 

 them, when it cannot be done by raifing the upper 

 glafles. If your foil is wet, the whole of the ftove 

 fliould be built above ground ; but, on the contrary, if 



you 



depth, and other dimenfions, fhould be conformable to 

 that of the ftoves, which will make a regularity in the 

 building. Theie may be placed at the end of the range 

 on each hand beyond the floves ; and if there be a 

 flue carried round each of thefe, with an oven to 

 make a fire in very cold weather, it will fave a great 

 deal of trouble, and prevent the frofl from ever entering 

 the houfe, be the winter ever fo fevere ; but the upper 

 glafles of thefe houfes Tnould have either fliiitters of 

 wood, or tarpavvlins in frames, to cover them in frofly 

 weather ; and if there is a contrivance to cover the up- 

 right glafles in frofl:, either with mats, fliutters, or tar- 

 pawlins, it will be of great ufe in winter, otherwife the 

 flue muft be ufed when the froil: comes on, which fiiould 

 not be done but upon extraordinary occafions, becaufc 

 the defign of thefe houfes is, to keep fuch plants as re- 

 quire only to be preferved from frofl, and need no addi- 

 tional warmth ; but at the fame time, require more air 

 than can conveniently be given them in a green-houfc. 

 In one of thefe houfes may be placed all the forts of Fi- 

 coides, African Sedums, Cotyledons, and other fucculent 

 plants from the Cape of Good Hope. In the other may 

 be placed the feveral kinds of Ar£lotis, Ofleofpermum, 

 Royena, Lotus, and other woody or herbaceous plants 

 from the fame country, or any othej' in the fame la- 

 titude. 



Thus, by contriving the green-houfe in the middle, 

 and one flove and a glafs-cafe at each end, there will be 

 a convenicncy to keep plants from ail the difi'crrnt parts 

 of the world, which can be no otherwife maintained but 

 by placing them in diffen^nt degrees of heat, according 

 to the places of their native growth. 



The floves before dcfcribcd arc j'uch as are ufiialiy built 

 to maintain exotic plants, which will not live va Englcnutt
