From John R Denyer
To J S Salt
London
Commenced ice breaking but progress likely to be slow due to thickness of ice which must be very considerable in the upper levels, being 6 inches in some of the levels in this valley. Charge made by Mr Parker of inconvenience and delay to Fly Boats by the ice in T&S Canal while other canals remained navigable is not well founded.
