district, and naturally of an adhesive character, one 

 half the Tolume of the border should be above the 

 ordinary ground level. The most perfect drainage 

 in such cases must precede all other operations ; with- 

 out this the whole must ultimately prove a failure. 

 In ordinary cases, and where no particular suspicion 

 rests as to the retention of water, one bold main 

 drain, communicating with the porous substratum 

 (and placed one-half of its depth below the level of 

 that body), will suffice. If, however, the ground is 

 naturally damp, cross drains must be had recourse 

 to ; their frequency corresponding with the amount 

 of water to be drawn. In general, such cross drains 

 may be placed about fifteen or twenty feet apart. 



Much has been written about impervious bottoms 

 of concrete, &c. ; we, however, are decidedly opposed 

 to them. They are, at the best, doubtful on the score 

 of principle, and decidedly objectionable on the score 

 of expense. They moreover serve to render a matter, 

 perfectly sim.ple in itself, complicated ; and may serve 

 to deter many persons from attempting the cultiva- 

 tion of this luscious fruit, which is certainly within 

 reach of all who can command a wall, and can bestow 

 a little attention occasionally. 



The under-drains being established, the next thing is 

 to place a considerable body of any broken, porous, and 

 imperishable material over such drainage. Broken 

 bricks, stones, or scoriaceous matter is the sort of
