 they have an admirable appearance. Twelve 

 inches of interval is also required between 

 the ascending stems, and not less than two 

 trees should be planted to train on the same 

 wires. These Spiral Cordons bear remarkably 

 well, and for pot culture are unrivalled. The 

 sun and air have free access to the open centre ; 

 the leaders are kept down, and the spurs on them, 

 with due respect to the outrageous verticals, are 

 easily managed. They should, in the case of 

 pots, be pinched in more closely, as it is difficult 

 then to allow a clear twelve inches of interval. 

 The outgrowing shoots are, of course, not in-
