Mrs Jarrett has been in Paris tracing the English female detective sent over by the Government. She discovered the procuress Jtffries at Brussels, and offered, her a large sum to return to * ngland and give evidence as to the position in society of the houses where traffic in young girls is alleged to have been crrried on. It is reported that Jeffrie.- is willing to make startling dinclo- Rur^s, if guaranteed, against further prose •ution. i he Meih"dl*rB and their agents are sup porting Mr Ste*d. the accused editor, and a«sert that they h-tve inearthed evideice that Howard Vincent, I>irecTorof the Detec tive Department at fc CO' land Yard, recently testified before the Commission ot the House of Lords, to the tff- cfc that in many parts of London any number of girls of 14 or younger may be ob'aiued for tne vile-t purposes. In fact, he assured the Commit sion that these children were regularly sold with the full knowledge and connivance of their mothers, who looked to this means of meeting the hou>-ehold expem-es with unnatural complacency.
