The location must be somewhere temperate as we see a tree bare
of leaves, so let's assume it's somewhere like Yorkshire.
What time of day is it?
It must be about noon. Yorkshire is about 54 degrees North, so
the maximum height of the sun at noon near the equinox is about
36 degrees, and the shadows seem to be less than the height of the
objects casting them, so the sun must be very high in the sky for
early Spring or late Autumn.
Is it early spring or a late fall(autumn)?
Spring, because the farming activity looks like preparation of the
ground rather than harvesting. However, whatever is being done seems
to leave no mark, since the farmer and tractor are in the middle of
the field, yet neither left nor right is there a visible difference
showing the part already worked on.
Is this river navigable?
Obviously. There's a boat in it. But navigable is a relative term. It's
very unlikely to be navigable for an aircraft carrier.
Which direction does the river flow? (North, East, South or West?)
Since it's close to noon, the sun must be to the South, and the
river is flowing left to right, so it must flow South.
Is the river deep or shallow at the side where the boat is?
Compared to what? It's probably about waist deep. Where rivers are
straight they tend to slope down from the bank. The presence of the
jetty proves that it's not deep enough to get the boat right up to
the side. It looks like there's a float on the boy's fishing line, so
within the reach of his ability to cast, the water must get deep enough
that the hook is still above the bottom - probably over 3m. Note that
the total length of a fishing line on a river is irrelevant, as it
is often used to cast futher away from the bank rather than to get deeper.
Is there a bridge across the river somewhere nearby?
It's impossible to tell. The people using the boat suggest that they
cannot use a bridge, but that may be be because they're going to an
island in the river whereas the bridge is further downstream and only
goes to the other side. Also, there could be a railway bridge which
is not open to foot traffic.
How far is the railroad from here?
It's very difficult to tell. The man on the left might be a railway
worker, but even if he is, he's carrying quite a large case in his
left hand, so he could be travelling some considerable distance
from it. Either that or he has an extraordinarily large lunchbox.
Do birds fly North or South?
Some do, some don't. Some overwinter in England, having come from
further North, some spend the summer in England and overwinter
in Africa. The ones in the picture are flying more-or-less West.
