Question

I could not build billycarts very well. Other children, most of
them admittedly older than I, but some of them infuriatingly not,
constructed billycarts of advanced design, with wooden frames
and steel-jacketed ball-race wheels that screamed on the concrete
footpaths like a diving Stuka. The best I could manage was a sawn-
off fruit box mounted on a frame of fence-paling, with drearily silent
rubber wheels taken off an old pram. After school and at weekends
boys came from all over the district to race on the Sunbeam Avenue
footpaths. There would be twenty or thirty carts, two thirds of them
with ball-race wheels. The noise was indescribable. There would be
about half an hour's racing before the police came. Residents often
took the law into their own hands, hosing the grim-faced riders as
they went shrieking by.
