Shaun wrote "The swimming hole at the Weir must have been somewhere on the tributary of the R. Arun. There is no road to the spot so there must have been access by private arrangement with the school."

"Attached map shows almost the exact location of the weir pool, which was, as you guessed Shaun, approached by a private farm track and then a path across a field. (Stephen)"

(George replied to Stephen) "I really can't remember where we walked - it seemed a long way though! Steve, I concur with you entirely on the site of the weir, and remember nipping into the village shop for a small bag of lemonade powder whilst marching crocodile fashion for our swim on hot days, and trying not to get too far behind the procession which would have resulted in some penalty - probably be banned from swimming on that day!"

After much searching of old maps, I found one from wartime days with Wisborough (excerpt):

and also a detailed up-to-date map of the exact spot (seems to marke the weir too!):-


The much-improved Google map shows that the location pointed to above was on the River Kird (tributary of the Arun). Here is Google Map's view of the spot Stephen indicates:-

My having put forward an alternative theory as to location (see lower down - a lot of wasted work now!), both Stephen and George demur and are quite certain that the spot, that decides the matter for me. Stephen:- "In my clear memory, the route to the swimming place was along the road from WL to the village and beyond, on the A272 towards Petworth. A bit west of the village green we turned left down a farm track and then at the end of that we went across fields (on one occasion allegedly containing a dangerous stallion, or as I heard it, Italian) to the very small weir pond, with a low brick wall on its northern edge and the weir gate to the east. Ordnance Survey Landranger map 197, map reference approximately TQ 045255 (i.e., almost exactly where I claimed before). The walk from the school cannot have been less than about 20 minutes, in my memory, though memory is a notoriously unreliable faculty." To which George responded: " And I think I can reassure you on this occasion about memory tricks. The swimming site was exactly as stated by you, and the distance/time from WL is about right as well even allowing for the purchase of lemonade powder from the village shop. But Rob I don't recall the demand for boys to swim naked. Was that for the gratification of certain perverted teachers!"

I replied "Your additional vote decides the issue for me. Maybe it was because you and Stephen (my elders) went to swim more than twice, as I did only? Indeed, it was Col. Kennedy who insisted that we all bathe naked in the square brick-walled pond, which Stephen describes accurately. I was there with about 10 boys and Kennedy once… it was supposed to be acquaintance with the water for non-swimmers. But the pond was some way away from the weir where swimmers went, as I recall? That pond has awful weeds growing across the bottom, most unpleasant it was then."

I wonder also if Tanyard Copse (see map above) was where Mr. Brooke-Little took us for 'wide games' - once it was flag-raiding and another time a paper chase.
