Dr. John Walker devoted almost 46 long columns of his 'Sufferings' to criticise it, but admitted that he had 'never read the Act,' with the result that he refers to Vavasor Powell as Commissioner as well as Approver; Carlyle points to no portentous moral over that 'case of Wales' in Cromwell's speech of 4th July, 1653, and his explanation of the 'wolfish' men in the context is open to serious doubt; and the great historian of the Commonwealth, though admitting the importance of the Act in the politico-religious issues of the time, only devotes a little over two pages to it; judging fom the references to the foot-notes, his acquaintance with Propogation evidences does not pass beyond the shorter diatribes of Alexander Griffith.
