penman. The old building on the right, it must be understood, is
not a mere accessory, but is an essential part of the picture. The
matter of surroundings is the first we have to decide upon, and
these ought always to be disposed with reference to the particular
form of composition which the subject may suggest. Were we dealing
with the foreground building alone there would be no difficulty
in adjusting the oval or the diamond form of composition to it.*
As it is, the difficulty lies in the long crested roof-line which
takes the same oblique angle as the line of the street, and the
influence of this line must be, as far as possible, counteracted.
Now the heavy over-hang of the principal roof will naturally cast
a shadow which will be an important line in the composition, so we
arrange our accessories at the right of the picture in reference
to this. Observe that the line of the eaves, if continued, would
intersect the top of the gable chimney. The dwelling and the tree
then form a focus for the converging lines of sidewalk and roof,
thus qualifying the vertical effect of the building on the right.
As the obliquity of the composition is still objectionable, we
decide to introduce a foreground figure which will break up the
line of the long sidewalk, and place it so that it will increase
the influence of some contrary line, see Fig. 59. We find that by
putting it a little to the right of the entrance and on a line
with that of the left sidewalk, the picture is pleasingly balanced.

We are now ready to consider the disposition of the values. As I
have said before, these are determined by the scheme of light and
shade. For this reason any given subject may be variously treated.
We do not necessarily seek the scheme which will make the most
pictorial effect, however, but the one which will serve to set
off the building to the best advantage. It is apparent that the
most intelligible idea of the form of the structure will be given
by shading one side; and, as the front is the more important and
the more interesting elevation, on which we need sunlight to give
expression to the composition, it is natural to shade the other,
thus affording a foil for the bright effects on the front. This
bright effect will be further enhanced if we assume that the local
color of the roof is darker than that of the walls, so that we
can give it a gray tone, which wil
