floor with light and shade, are the most truly natural, and, perhaps, 
the most delightful of any kind of arbour. 
To the second kind belong all those which are formed by the hand 
of man, aided by some natural suitability of circumstances, or acci¬ 
dental advantages. Thus an aged forest tree may have some appro¬ 
priate climbing plant, placed at its root, so as to run through its 
branches and foliage, and ultimately descend gracefully from their 
extremities, until it nearly touches the ground, as in Fig. 3. 
Fir. 3. 
The vast hollow trunk of an aged oak may be mantled with ivy, or 
with honeysuckle, and block seats placed within. To this order, 
likewise, belong those which are made by enclosing a space of any 
desirable form, perhaps circular, with the trunks of trees, choosing 
those which are roughest and most moss-grown, fixing them firmly in 
close array in the ground, and closing in the arched top with their 
branches. Various climbing plants may then be planted at their bases 
on the outside; amongst which ivy, in its varieties, should not be 
forgotten : these will soon cover over the whole with a dense envelope 
of foliage and flowers, while within amongst the roots of the trunks, 
and the block seats, primroses, violets, ferns, and other plants that love 
shade, and even some small American plants, will thrive. (Fig. 4.) 
The construction of this kind of arbour depends much on the chances 
of situation, and many designs or minute instructions would be, there¬ 
fore, superfluous. 
Arbours of the third kind are now but little used, indeed are 
scarcely to be seen in this country. They were usually formed with 
much attention to architectural outline of wood, or iron or copper wire 
trelliage; in the construction and arrangement of which much skill
