damp ?

rising or from above ?
I live in a terrace of 3 storey solid stone walled miners house the ground floor is a cellar which opens onto the rear garden and is below front door (street) level
back / \ front |________| |________|____ ___|____|
the cellar is soaking 1/2 way along 1 adjoining wall and into the corner of the rear facing wall
next door (as with all the houses in our street) has a yard area higher than the cellar along this same wall but there doesn't appear to be anywhere where the water can be seeping from other than their main drain which is on the other side of their yard. about 6 feet away. could this be the source of the damp or can rising damp (there are no foundations or cavities) rise 7 feet up a wall ?
how can I find out where the damp is coming from (cheaply) ?

You could use a tracer like they use for tracing underground streams, and sprinkle some on next door's yard.
This type of construction often has a stone drain at the foot of the wall. There may be one under the edge of next door's yard, and one at the foot of your cellar wall. They are formed by putting a line of stones on edge about three or four inches in from the wall. The stone flags on top then form a channel which usually leads to the outside. Over time these channels become blocked with silt. Another favourite is someone blocking the channel putting in new drains, or utilities installing services and not knowing what all these bits of stone are for.
You can often flush out stone drains with a high pressure hose, but you have to find out where it comes out and work "uphill".

Moisture can enter a building at one point and be visible somewhere else.
Ground contains water and so there may be no one source of the damp.
If there are no obvious bursts or leaks, or breached damp course then you may just have to get your cellar re-tanked to seal out the moisture.
A camera survey can detect a broken drain.
