The letterpress text explains the benefits of this scheme, lists the objections raised and, in a partisan fashion, rebuts the objections.
The second map (190 mm x 265 mm), copied from Thomas Acherley’s (the previous item), is accompanied by the extract of the document that criticizes (again in a highly partisan fashion) his proposals, concluding that his scheme was unworkable.
In fact, it was the Blackmore scheme that was judged unviable, in that there was insufficient “drop” to create a flow from the Colne to the reservoir in London, while Acherley’s scheme, though possible, never garnered the support necessary to proceed.
