asked the Secretary of State for War what proportion of Class Z reservists have failed to reply to their call-up notices to date; and how many notices have been returned to his Department as untraceable.

Some 7.4 per cent. of reservists warned for recall have not yet acknowledged the receipt of a warning notice. Acknowledgments are, however, still being received. In addition, 1,734 warning notices, or some 0.9 per cent. of the whole, have been returned as untraceable.
