than fix Feet long, are too heavy 

 to move, efpecially if the Frames 

 are made of a proper Strength to 

 fuftain the Glafs. Thefe Frames 

 mould be contriv'd in fuch manner, 

 as that the upper Row may Aide 

 down j and by making on one Side 

 three fmall Holes in the Wood-work 

 which fupports the Frames, at about 

 a Foot Diftance, and having a fmall 

 iron Pin to fix into them, the top 

 GlafTes may be let down one Foot, 

 two Feet, or three Feet, according 

 as there may be Occafion. Trie 

 lower Row ! of GlafTes may be con- 

 trived fo as to take eafily out : but 

 as they muft lie (loping, and the up- 

 per Row muft: bear on them, they 

 cannot be contriv'd to Aide up- 

 ward ; nor indeed will there be 

 any Occafion of their moving j be- 

 caufe it is much better to let the Air 

 in at the Top, than in the Front of 

 the Tree:-. 



The Hoping Timbers, which are 

 to fupport the Glafs-frames, muft be 

 failen'd at Bottom, into the Ground- 

 plate in the Front of the Border, 

 and at the Top into ilrong iron 

 Cramps fix'd in the upper Pare of 

 the Wall for that Purpofe. Thefe 

 Timbers mould be made of Fir, 

 which will not twill as Oak and 

 fome other Wood will, where it is 

 laid in fuch Pofition. They muft 

 be made fubftartial, otherwife they 

 will not laft many Years, efpecially 

 as they are defign'd to be moveable. 

 On the Top of thefe mould be fix'd 

 a Ilrong Board, under which the up- 

 per Row of GlafTes mould run. The 

 Ufe of this Board is, to fecure the 

 upper Part of trie Glafies from be- 

 ing rais'd by the Winds, and alio to 

 keep the Wet from getting to the 

 Trees : therefore it mould be joinM 

 as clcfe as pofftble to the Wall, and 

 mould project ^ about two Inches 

 over the Glafs-frames j which will 



he enough to throw the Wet on the 



GlafTes, and likewife to fecure them 

 faft down. 



The Breadth of thefe Frames for 

 the Glafies may be about three Feet, 

 or a little more, according as the 

 Divifions of the Length of the Wall 

 will admit ; for a fmall Matter m 

 their Width is of no Confequence, 

 provided they are not too wide to be 

 eafily moved ; for when they are 

 wider than a Man can eafilv reach 

 with his Arms, to manage, they 

 will be very troublefome to carry 1 

 from cne Place to another. The 

 Bars of thefe Frames, which are to 

 fupport the Glafs, mould be piae'd 

 lengthwife of the Frames ; for when 

 they are plac'd acrofs, they flop the 

 Moifture which is lodg'd on the In- 

 fide of the GlafTes, and caufe it to 

 fall in Drops on theBorders at every 

 Bar ; which will be very injurious 

 to any Plants which are put there ; 

 and, if it falls on the Trees, will 

 greatly damage them, efpecially 

 when they are in BlofTom. The 

 Lead into which the GlafTes of thefe 

 Frames are fix'd, mould be very 

 broad, and the Joints well cement- 

 ed ; otherwife the Wet will find an 

 eafy PafTage thro', and do great Da- 

 mage to the Fruit. 



At each End of the Range of 

 GlafTes, there will be an angular 

 Space between the Glafies and the 

 Wall, which mult be clofely ftopp'd 

 to prevent the Air from getting in, 

 which might greatly .injure the 

 Fruit. Thefe are by fome Perfons 

 clofely boarded up; but if they are 

 clofed with Glafies, fo contriv'd as 

 to open to let in Air at proper times, 

 it will be of great Advantage ; be- 

 caufe when the Wind may be toi 

 ftrong againfl the Front-glafTes, on-; 

 or both of thefe End-glaiies may b? 

 open'd, according to the Warmth of 

 the Air inclpyi'i which will be
