corridor, that of construction, ought evidently 
to operate in a landscape designer, though the 
practitioner has only to design : but in design- 
ing, the execution of the design is kept in view, 
else schemes might be propounded, the realising 
of which might be impossible. It appears to 
make clear the conception of how a thing may be 
done, and likewise how it ought to be done, when 
more ways than one of doing present themselves. 
It is intimately connected with what is called 
intervention, and may possibly be identical with 
it. For everything is constructed in the mind 
before the hand is set to execute. With a few 
observations on colour, and remarks on one or 
two collateral subjects, I shall conclude what I 
have to say. Besides the power of vision, pro- 
p erly so called, and which makes us aware of the 
presence of objects, there exists a particular fa- 
culty which takes a judicial notice of colour. I 
have known persons, who, not possessing this 
faculty in a sufficient degree, mistook one colour 
for another, and could not distinguish them. 
Some persons, again, have so strong a passion for 
colour, as to delight in its contemplation, with- 
out any regard to harmony or fitness, The land- 
scape designer must possess this faculty in a pro- 
per degree : he must have not only a quick per- 
ception of mere colour, but of harmonious ar- 
rangement, and the effect of shade, and of one 
colour upon another. The vegetable world pre- 
sents every variety of colour, but the landscape 
designer has to do with but a sm all number, and 
cl lie i ly with varieties of green, and the varying 
hues of spring and autumn. Nor is this all ; he 
must be acquainted with the season at which each 
tree or shrub shoots forth and sheds it3 leaves. 
This require^ not a little study. Then comes the 
selection of sha le3 of foilage and styles of growth 
adapted to various situations and special scenery. 
Nature tells us not only in what situations cer- 
tain trees will live and grow, but she has genera 
and species for every climate, so that few posi- 
tions suited to the dwelling of man are without 
something that is gratifying to the eye ; and 
where there is deficiency, it is in his power to 
supply it. Man was not created to be idle, and 
every inducement lias been’ held out to him for 
exercising the powers with which he lias been 
endowed. The wildest wastes of Australia' are 
capable of improvement, and the only obstacle 
to its being effected is to be found in the want of 
means. Wealth is necessary to reclothe the sur- 
face ; but alas, where wealth should most abound, 
there does poverty extend the farthest. Were 
riches expended in the improvement and embel- 
lishments of land, instead of being scattered 
abroad as they too frequently are in useless and 
unsatisfactory luxury, sufficiency might be en- 
joyed by all. The variety of green tints is very- 
great, and their disposition of importance. Green 
is a mixture of blue and yellow, and the preva- 
lance of either must be studied. Evergreens 
should generally be so disposed as to form a mass 
when other trees are naked. Single pine3, firs, 
bamboos, and palms, if room be given them, 
produce a fine effect. 
When a house is to be built where trees already 
abound, difficulties will occur in choosing a situa- 
tion. It is dangerous to cut down trees before 
the building has been erected, and yet effect may 
not bo brought out so as to assist in the choice 
without thinning. It is difficult to conduct roads 
where trees stand thickly ; in such a case the 
landscape designer should proceed with great 
caution, removing first such trees as are not in 
themselves worthy of a place. Of all things con- 
nected with landscape designing’ buildings are 
often mo3t offensive ; and wo find the grossest 
defect of ta3te frequently displayed both in their 
style and position ; many persons are apt to asso- 
ciate external nature with the state of society in 
times long past. This is an error that has led to 
many trespasses against nature’s rules. A man 
will build a castle, because the situation he fixed 
for it is a commanding one. His taste leads him 
into expense, and to the sacrifice of convenience 
and comfort. D welling-houses should be ar- 
ranged for comfort, and where means are at com- 
mand ; also for elegance and grandeur, both in- 
ternally and externally. The ruins of ancient 
buildings' produce a most pleasing effect ; and 
they ought to be preserved. But it would be 
preposterous in our day to build that which is 
felt to be impressive only when in a state of ruins. 
This is a subject not altogether separated from 
landscape designing, when a professor finds build- 
ings in his way, it is his business either to hide 
or to exhibit them to the best advantage.
