558 TRANSPLANTING LARGE TREES. 



injured, the soil good, and that they he kept well sheltered, 

 and watered. 



" In choosing the tree to be transplanted, its age and 

 species must be duly considered. For instance, it is useless 

 to remove a tree that is sixty or eighty years of age, as it 

 will never produce as fine foliage as it did before its re- 

 moval, nor will it make any remarkable progress in size. 

 It is better only to remove those not more than fifteen years 

 old and under without any earth-ball at all, taking especial 

 care to preserve all the roots intact. The best age for trans- 

 planting larger trees is from twenty to thirty years. The 

 number pf species ordinarily removed is limited, as only the 

 more common kinds of trees are subjected to the process, 

 no one caring to run the risk of losing a rare and valuable 

 tree. In Paris, experiments made on various species have 

 given the following results : — 



" Success nearly always certain : Elms, Planes, white 

 and red, Horse-chestnuts, Limes, Ailantus, Catalpa, 

 Paulownia, Celtis, Planera, Sophora, and Willows. 



" Success uncertain but sometimes satisfactory : Poplars, 

 Sycamores, Maples, Alders, Mulberries, Beech, Ash, Mag- 

 nolias, American Walnuts, Cercis, Diospyros, and several 

 other exotic trees not yet sufficiently experimented 

 upon. 



" Success very rare : Robinias, Crataegus, Hawthorns, 

 and nearly all the Rosacese, Birch, Laburnum, and many 

 Leguminosae, Oaks (European and American), Pavias, Elms, 

 and Gleditschias." 



With respect to the value of this machine as compared 

 with any in use in England, there can be no doubt that the 

 Paris machine is the best. Trees are there removed daily 

 without the least difficulty or fuss, that, if removed in this 

 country, would probably be honoured with a notice in the 

 local papers. The best of our English machines must be 

 taken to pieces for the removal of every tree : the beams 

 have to be taken off in order to bring the wheels in position, 

 then they have to be replaced in position, as well as the 

 lifting apparatus. Besides, the machines are unwieldy and 

 awkward. The advantage of the French machine is, that
