place, and the empty space is soon refilled. Lastly, tliis form of 

 training is very easily accomplished, and the regular inclination 

 of the stems renders the means of equally distributing the action 

 of the sap extremely simple. 



As to the productiveness and longevity of trees thus trained 

 we are perfectly satisfied, both by those which were planted by 

 us 10 years ago in the Garden of Plants at Kouen, and by otliers 

 since planted in the environs of Paris, and all of which are quite 

 equal to those treated in the ordinary way, that in this respect 

 the above plan is inferior to none. 



But as we have said, the plan can only be followed in the case 

 of Peach-trees. The following arrangement, wiiich is quite new, 

 appears to us to be ai)plicable and with similar advantages to 

 trees of other sorts. 



Double oblique Course {Jig. 3). — The only difference between 

 this and the arrangement already described is that in the latter 

 the perpendicular distance between the stems was 2 feet, whilst 

 in this it is only 1 foot. That is the space which ought to sepa- 

 rate the branches of a Pear-tree, which ha.s been taken as an 

 example in the figure. This necessity, however, gives rise to 

 another ; the trees being planted at a distance of nearly 3 feet 

 from each other, in order to attord their roots sufficient room, 

 two branches have to be developed instead of one as before. 



This sort of training is established as follows. The trees 

 should be strong maiden plants ; they should be planted ver- 

 tically with proper care in the places marked. The fir-^t year 

 nothing more is to be done than to remove portions of the .stem 

 in order to establisi) an equilibrium between it and the roots. 

 The next year a single shoot at the top of each stem must be 

 left to grow vigorously, all the others being converted into spurs 

 by the proper means. In the spring of the following year, the 

 young trees having taken goofi hold of the ground, and already 

 grown, each stem is to be inclined from its base at an angle of 

 45°. During the succeeding summer one vigorous shoot is al- 

 lowed to develope in a vertical direction inmiediately above the 

 bend. In the 4th spring the branch produced by this bud i.s 

 itself bent, half a yard above the ground, parallel to the first 

 branch. 



Care is to be taken during the next summer to maintain an 

 equal vigour in the two branches of each tree, and to promote 

 the vigorous growth of each terminal shoot by converting all the 

 others into spurs. In pruning, about 32 inches of the leading 

 shoots should be left, unless they are of unequal strength, in 

 which case the strongest is cut shorter. The same operation is 

 repeated eveiy year until the trees reach the top of the wall.
