APPENDIX. 205 



" The stem of the plant was about a foot in height before 

 any branches set out; on one of the branches, above two 

 feet from the junction with the stem, a root was put out. 

 As soon as this had grown about a foot long, I placed a pot 

 under it. As soon as I found this pot filled with roots, I 

 determined to try whether if supplied plentifully with water 

 it would support the whole plant. 



" In August 1816, 1 left off watering the original large pot, 

 and supplied the smaller one very freely with water ; I kept 

 it in this state for about eight months, till the earth in the 

 large pot was so completely dry, that I was satisfied the 

 plant could receive no nourishment from it. The shrub 

 continued quite as healthy and vigorous as when supplied 

 with water at the original root. In the spring of 1817, I 

 took off the large pot in which the original roots were, and 

 exposed the roots to the full rays of the sun, by gradually 

 shaking off the dry earth from among them ; this had no ill 

 effect on the plant, as it still remained perfectly healthy ; 

 it, however, had the effect of making roots be put out freely 

 all over the plant, much more so than had hitherto been the 

 case. 



" In the latter end of the summer of 1817, I placed a root 

 in a third pot, which was put out from a branch about three 

 feet from the junction with the stem, and on the opposite side 

 of the plant from that which had supported it for some time 

 past. As soon as I found this pot filled with fibres, I sup- 

 plied it freely with water, and kept the other small pot dry, 

 as I had done before with the original root. I found the 

 plant still continue equally vigorous as before. In the 

 spring of 1818, I took away the second pot, which I had 

 for some time kept dry, and exposed the roots gradually, as 

 I had formerly done with those in the original pot. 



" The third pot, which now alone supported the plant, was 

 four feet from the lower end of the stem, and very near to the 

 extremity of the branch, the original roots, and the second 

 set of roots, both hanging loose in the air. The plant, how- 

 ever, remained in this state for nearly a year in perfect
