as in the case of this Safety Detaching Hook of Mr . Walker ' s , the government of every civilised nation ought to reward him liberally for his services , ancl insist upon its adoption wherever necessary , leaving the manufacture to any maker , only exercising proper supervision to insure that no worthless imitation is sold for the
genuine article ; giving long imprisonment to any knave who sought to enrich himself by dishonest means . Although residing in Cleveland , Mr . Walker is as personally unknown to me as though he had lived all his life in Timbuctoo , and of the
Birmingham firm AVIIO manufacture his important Detaching Hooks I am equally ignorant . Not so , hoAvever , Avith the Detaching Hook itself , Avhich was satisfactorily tried at the Stanghow ironstone mines in the autumn of 1874 , in the presence of several
mineowners , viewers , miners , and delegates , and met Avith their unanimous approval . Since then it has been regularly used in several coal-mines in Wales , the county of Durham , and other places , as well as in the Cleveland ironstone mines , and has never been known to fail . It needs no very refined feelings to feel shocked at the numerous accidents one sees recorded in
the newspapers as the result of over-winding , and it is Avell enough to convict a careless attendant of an engine at a pit shaft of manslaughter when such dreadful accidents occur . But this does not bring the dead to life again , ancl is small comfort
to their bereaved friends . Now that Mr . Walker has invented ancl properly made knoAvn his invaluable discovery , should I ever be on a jury where the workmen Avhen arriving at the top of a shaft are pitched clown again ancl killed through
over-winding , I will certainly hold out for a verdict of manslaughter against the parties who have neglected to provide for the proper safety of the men Avho toil in the boAvels of the earth to enhance our national Avealth in general , and theirs in particular . The
wages paid and received is a matter with Avhich employer and employed have alone a right to interfere : the safety of the lives of my felloAv-creatures , Avhether employers or employed , —in fact all , from the Queen on the throne to the most Avorthless idler in a vagrant ward , is my business , ancl the business of every other citizen . Ancl , above
all men , the honest Freemason , who did not make a false declaration when on his initiation he solemnly declared that he was really anxious to make himself more serviceable to his fellow-creatures—though at perfect liberty to hold any theological or political opinions that may commend themselves to
his judgment—has no right to rest contented to make a good living in a whole skin , whilst his more exjiosed felloiv-men are being dashed in pieces through Avanton carelessness , though that carelessness does not immediately concern him . " I am a
