Here also must be noticed certain practices, wHcli experience 

 shows to be important, of which theory offers no satisfactory 

 explanation. Mr. Knight, for example, asserts that cuttings 

 taken from the trunks of seedling old trees grow much more 

 vigorously than those taken from the extremities of bearing 

 branches; and it is an undoubted fact that the Beech, and 

 other trees of a similar kind, cannot be grafted with any 

 success, unless the scions are made of two-years-old wood ; 

 one-year old wood generally fails. Some recommend taking 

 scions from the shoots produced at the extremities of healthy 

 vigorous trees. And this is much insisted upon by M. De 

 Jonghe, a very experienced practical as well as theoretical 

 cultivator. D'Albret, however, entertains a different opinion, 

 and considers the following experiment conclusive. 



" Some years," he says, " before the first transfer of the Ecole 

 des Arhres Fndtiers du Ja/rdin des Plcmtes, effected in 1824, I 

 was obliged to take grafts from more than four hundred trees, 

 of different sorts, in a state of complete decrepitude, often 

 covered with canker, &c. Such grafts put on healthy young 

 stocks all grew with remarkable vigour, and the trees raised 

 from them when from twenty to twenty-six years old, many 

 being more than thirty-six feet high, all bore fruit in prodigious 

 quantity, and were free from disease, when they fell under the 

 axe in 1841." 

 , Shoots for grafting and budding, says D'Albret, are not easily
