 It would seem that the principle might be preserved 

 in better form by the horizontal trellis, as previously de-

The usual modes of training upon arbors is very imper- 

 fect; an upright cane being allowed to furnish shoots for 

 the side, and also arching over the top for the same pur- 

 pose. The flow of sap being towards the top, of course 

 the growth on the top will be excessive and succulent ; 

 and in its high position, being exposed to drafts, it is very 

 liable to suffer from mildew. The shoots on the side of 

 the arbor, not receiving a due proportion of the strength of 

 the vine, are almost sure to be weak in growth, producing 

 little fruit. It would be much better to plant a larger 

 number of vines, and train them on the Thomery plan, 

 so that the bearing-shoots on each individual vine shall 

 all be on a level, and no one of the shoots be allowed to 

 grow higher than the rest on the same vine. This reduces 

 them all to a perfect equality. By this means we shall 

 never be troubled with long naked canes on the sides, 

 with here and there a weak and barren shoot.
