\JQ ADVANTAGE OF GRAFTING CERTAIN TREES. 



detached from the old trees, and employed as grafts, would 

 still retain the character and habits of bearing branches. 

 Experiment Having therefore planted in the spring of 1799 some wal- 



nut!* " nut trees > °* two y ears °W, in garden pots, 1 raised them up 



to the bearing branches of an old walnut tree, by placing 

 them on the top of poles placed in the earth; and I grafted 

 them, by approach, with parts of the bearing branches of the 

 old tree. A union took place during the summer, and in the 

 autumn the grafts were detached from the parent stock. 

 The plants thus obtained were planted in a nursery, and, 

 without any peculiar care or management, pioduced both 

 male and female blossoms in the third succeeding spring, 

 and have since afforded blossoms every season. The frost 

 has, however, rendered their blossoms, as well as those of 

 other trees in their vicinity, wholly unproductive during the 

 last three years, and in the spring of 1805, almost wholly

 freny« riment was made in the same year, but under many disad- 



vantages, on the mulberry tree. I had not any young plants 

 of this tree, and therefore could only make the experiment 

 with scions of one year old ; and of these I had only two, 

 which had sprung from the roots of a young tree, in the pre- 

 ceding year. These were planted in pots, and raised to the 

 bearing branches of an old tree, in the manner I have already 

 described in speaking of the walnut tree. One of these 

 scions died ; the other, which had but very few roots, suc- 

 ceeded; and the young grafted tree bore fruit the third year, 

 and has continued annually productive. In the last spring I 

 introduced it into my vinery, where its fruit ripened, in the 

 greatest state of perfection, in the beginning of the present 

 month, [January, 1807]. 

 Grafting by ap- Both the walnut and mulberry tree succeed so ill when 

 them ei,ttor grafted, unless by approach, that I can scarcely recommend 

 attempts to propagate them in any other way ; but when 

 they succeed by other modes of grafting, nearly the same 

 advantages will probably be obtained : the habit of the 

 bearing branch is, however, least disturbed by grafting by 

 approach.
