 last autumn, and to be completed t/iis, which is now done at 

 GG i while the bending up of the bark-vessels at HH allows 

 the sap to deposit a new row of alburnum at II, which is also 

 seen at fig. 6, where the bending of the bark-vessels leaves it 

 free. They are soon straightened at K, by the enlargement of the 

 side of the circle, which the next spring will be made even by 

 another ro%y on the north side. F-ig. 7 shows the increase on 

 one side only, when the climate prevents exotics from receiving 

 their spring shoots in width, and this is no very uncommon 

 case. I have many specimens of the kind by me. Fig. S 

 shows the manner of forming the circles — when a tree is past 

 eighty, it then marks its lines between the others. But I have to 

 get more specimens^, which will complete my knQwledge in this 

 respect, which is yet partly but conjeccure, and therefore not 

 wholly to be trusted to. Fig. 9 is the manner in which the 

 wood-vessels draw one out of the other j but as they lengthen, 

 the upper ones soon decrease to the smallest size.

 vision of skill. Our fruit gardeners, who carry every sort of
