OF THE V I N E. 
Parallel to the drain adjoining the front of your Hot-houfe, 
another drain Ihould be made at the diftance of about 1 8 or 20 
feet, and this ought to be funk fix or eight inches below the 
level of the former drain ; the bottom floor of the vinery will 
then admit of an eafy defcent, lo that the water may readily be 
drawn oft from the roots of your Vines. 
When the foil comes under any of the above defcriptions, 
a bottom floor fhould be made to prevent the Vine-roots from- 
penetrating it : This floor mufl; be made of fuch materials as 
chippings of ftone, coarfe gravel, broken bricks, &c. and thefe 
mufl be laid quite as low as the bottom of both the drains, and 
to the thicknefs of eight or ten inches. They fhould be well 
beaten together and made fmooth. 
Over thefe materials, or foundation, there fliould be put a 
thin layer of fine loamy foil, quite free from fwarth or flones. 
This fliould be well watered, and worked over with a fpade till 
it is quite foft, fo as to have the appearance of a fluid mafs ; 
for then it will entirHy fill up the chinks in the under-bed of 
ftone, 6 cc. and alfo form a covering, and unite with it fo tho- 
roughly, as to make and compofe a firm bed, almoft as impe- 
netrable as a rock.'

* This method of tempering foil is in general practice with engineers and perfons 
employed in making navigable canals or large pieces of water. It is by them 
termed “ puddling,” and is deemed the beft expedient hitherto found out to render 
ground water-proof.
