asked the Postmaster-General whether the extra precautions taken in June, 1930, to safeguard mailbags during transit have had the effect of reducing cases of theft?

The number of these thefts, which is very small in comparison with the number of bags conveyed by railway, naturally fluctuates from time to time. I cannot say that the number of losses has been reduced recently, but the measures taken have resulted in the bulk of the losses being traced and a number of persons have been convicted.
