half way up. They are to be treated as 

 *'r2(/e?s," and to be made to cover all the 

 naked part of the wall or trellis, until over- 

 taken by the Forsyths, as they slowly ad- 

 vance to their growth. The French trees 

 should be set ofl' from the wall or trellis 

 sufficiently, so that the Forsyth branches 

 may pass behind their stems as they extend 

 laterally, and thus the wall will be com- 

 pletely filled with fruit in the course of time. 

 The mode of 'pruning these trees is alto- 

 gether difierent from that practiced on the 

 Forsyth trained trees to create fruit-bearing 

 shoots, and by the time these last have at- 

 tained their full growth, the French trained 



will have disappeared altogether, as their 

 branches have been successively cut off as 

 their horizontal-trained neighbors encroach- 

 ed upon them. 



At this slate of the trees, when the For- 

 syths will have the whole wall to themselves, 

 and when they have attained the utmost 

 height that you wish, say eight or ten feet, 

 and the sets of lateral branches are com- 

 pletely formed, the upright leading shoot 

 should be cut out, so that the laterals may 

 receive the additional sap, which has hither- 

 to been consumed by the leading shoot.

How far analogy may be depended upon, 

 for aid or guidance in our researches into 

 the hidden, or the unknown, of the vast 

 field of nature, is a point requiring to be set- 

 tled. How far it is allowable to go, and 

 where it may be necessary to stop, with 

 this mode of reasoning, needs to be defined. 



It will not be disputed, on the one hand, 

 that analogy is good as between similar 

 things ; and it is not denied, on the other, 

 that it is bad as between things dissimilar. 

 Analogy would fail us were we to attempt 

 to reason by it from mind to matter, or from 

 matter to mind. It will not hold, or but re-
