If a tres be placed in a high and expofed 
hituation, the new matter which it gcne- 
rates will be depofited chiefly in the roots 
and lower parts of the trunk, and its 
growth will be low and fturdy, and well 
calculated to refift the havy gales to 
which its fituation conftan'ly expo'es it. 
When a tree is wholly deprived of 
motion, by being trained to a wall, or 
when a large tree has been deprived of 
x's branches ; it often becomies unhealthy, 
and not unfrequently perifhes, owing. to 
the flagnation of the defcending fap un- 
der the rigid cinéture of the lifele%S ex- 
ternal bark. In proof of this he pared 
away this bark from fome very old pear 
and apple trees, and more wood was 
generated in the old trunks, within two 
years after this operation, than in the 
preceding twenty years ; which he attri- 
bites to the facility of communication 
which has been reftored between tne 
leaves and the roots, throuch the inner 
bark ‘for he has fiequently ob/erved that, 
wherever the bark has been moft reduced, 
the greatef% quantity of wood has been 
depotited, } 
Although Mr, Knight fuppofes that 
capillary attra€tion and a certain confor- 
mation of the veffels of the bark are 
caules of the defcent of the fap towards 
the root, yet he confiders gravitation, as 
the moft extenfive and ative caufe of 
motion, in the defcending fluids of trees: 
and he fees a reafon why it thould necef 
farily be fo; for if the fap paffed and re- 
turned as fively in the horizontal and 
pendent branches, as in the perpendicu- 
Jar branch, the growth of each would be 
equaliy rap:d, the former, would feon 
extend too far from its point of fufpen- 
fion at the trunk cf tne tree, and thence

This paper contains many other curious 
and interefting facts on grafting, budding, 
écc. and we are told that an examination of 
the manner in which wounds in trees be- 
come covered (for they can never be iaid 
to heil) affords further proof that the 
meduilary procefies, as thefare improperly 
called, like every cther part of the wood, 
are generated by the bark ; for whenever 
the furface of the alburnum is. expofed!’ 
but a few hours to the air, though no 
portion of it be deftroyed, Vegetation on 
that furface ceafes for ever. New bark 
is gradually protruded® from the fides of 
the wound, and thus new wood is gene- 
rated. In this wood, the medullary pro- 
ceffes are diltin@ly feen to take their 
origin from the bark, and to terminete on 
the lifelefs furface of the cold wood within 
tne wound. The concluding part of the
