be two feet thick, and the flues thus difpofed of ; the 

 fiill: flue to be two feet high, and nine inches broad ; 

 the fecond, one foot nine inches high, the breadth the 

 fame ; the third, fourteen inches high, and the fame 

 breadth J to be covered with brick four 'inches thick; 



and 



mend the latter for the convenience of giving air to 

 the plants, for there is no other contrivance in the firft 

 fort for adn-.itting the air, but by raifing the whole frame 

 on one fide in proportion to the quantity of air intended 

 to be admitted, and when the feafon is warm, they ge- 

 nerally raife thofe frames on both fides, and permit the 

 plants to run from under them. 



When thefe frames are made, if they are well paint- 

 ed over with the following compofition, it will greatly 

 preferve them, viz. to every fix pounds of melted pitch, 

 add half a pint of lintfeed oil, and a pound of brick 

 duft ; thefe fhould be well mixed together, and uied 

 warm ; when this dries, it becomes a hard cement, 

 fo that no mcifture can penetrate through it, and is 

 'the beft; fort of pigment for all timber expofed to the 

 weather, I have ever feen ufed ; fo that where the co- 

 Jour is not ofFenhve to the fight, it fhould be preferred 

 to every other. 



When the frames are thoroughly dry, the paper 

 fhould be palled on to the frames. The belt fort of pa- 

 per for this purpofc, is what they call Dutcb wraper, 

 this is flrong, and, when oiled, becomes very pellucid, 

 and admits the rays of light through it extremely well. 

 After the parte is well dried, the paper fliould be oiled 

 over on the outfide, which, if well done with lintfeed- 

 oil, will be fufficient, for the oil will foak quite through 

 llie paper, fo there will be no necelFity for oiling both 

 ficfes, nor for doing it over more than once. 'J he oil 

 fliould be dry before the frames are expofed to the we:, 

 otherwife the paper will tear. In the parting of the pa- 

 per on the frames, there Hiould be care taken to rtretch 

 it very fmooth, and alfo to parte it to all the ribs of the 

 frames, and alfo to the packtiircads, ro prevent the wind 

 from raifing the paper, which v.ould foon tear it, when 

 it bccartif ]'-nu\ 'l^jje
