and lightened on the other, so as to inclose the central shoot at A, as 
it were, in a dish or cup. By this means, the vivid yellow green in the 
centre at A , will remain there , and D D D will come forward to the eye, 
whilst the other leaves will keep in their respective places. But still the eye 
will be too much attracted to the centre, and D D D will want more assistance 
to bring them as forward to the eye, as their natural situations require. 
For this, we must have recourse to some accidental circumstance, that may 
with propriety be made use of to assist them: for instance, a young broken 
shoot of the fern accidentally lying upon them, into which may be thrown 
a still more vivid yellow green than that at A, which would immediately 
fling that back and D D D would attract the eye first, especially as the con¬ 
trasting tints near them would assist and produce the desired effect. 
I mention this, as only one mode of doing it; but the various ways that 
it might be done, will occur without difficulty to a pencil guided by taste 
and judgment; for to attempt it by altering or lowering the tone of colour 
in the centre, and increasing that at B D D, &c. would not be to describe 
the plant truly, to do which its real colour must be strictly adhered to.
