THE ROOTS OF GRAPE VINES. 181 



can be taken up and removed, if circumstances should 

 at any time render it necessary, without disturbing the 

 roots of the other vines. 



7th. The cross-walls being all finished, they had 

 better be left for the space of three or four days for 

 the brick-work to become dry and firmly set, after 

 which, the materials, being prepared in the manner al- 

 ready mentioned, may be deposited in the spaces betwixt 

 the walls. 



They should be filled in by the hand, in moderate 

 quantities at a time, and place carefully and compactly 

 together, clear up to the tops of the walls, so that the 

 under sides of the flooring-bricks, when laid, may be

 ends will then rest on the cross-walls, for which pur- 

 pose they are expressly built. 



Now it must be particularly observed that that row 

 or course of bricks that runs from the front of the house 

 to the back, which is the centre row of each compart-

 roots planted, is not, when put down, to be cemented 

 with mortar or anything else, but laid edge to edge and 

 fitted in closely, without any joints being made, other 

 than those which the bricks themselves make, so that 

 they can easily be taken up, and laid down again, at 

 any time when it may be thought necessary, for the 

 purpose of increasing the moisture of the bed of ma- 

 terials by adding water or liquid manure. The whole
