1-10 W TO SEND YOUR LETTERS

ON SUNDAY.
(From The Leader.)

Various expedients are offered to the public as sub-
stittites for the Post-office oa Sundays. Companies
undertake the conveyance cf letters ; news-agents in
some towns have adopted a very simple device, which
brings them in a revenue. They keep a box in their
shops open ; any customer who pleases may take the
liberty of depositing in this box letters properly
stamped, and accompanied by loose pence, one penny
to each letter ; the letters so found there are packed
up in a parcel and sent by railway to a correspondent
is the town to which they are directed; he opens the
parcel, and takes the liberty of posting all of these
stamped, oven on the Sunday ; they are found be-
times on Monday morning by the official people, and
sorted and delivered in due course.
No doubt this occasions a vast amount of labour
on the Sabbath, which was saved when all the work
was done by the practised and well-considered orga-
nization of the Post-office. But if private newsmen,
little blackguard boys from ragged schools, and other
abandoned characters in indefinite numbers, subject
themselves to the ulterior penalty of eternal torment
for the pence which the Post-office foregoes, Lord
Ashley has the satisfaction of reflecting that he has
coerced the elect few of the Post-office into "ever-
lasting redemption."

An order from the General Post-office, however,
suggests an expedient for saving this increase of
Sunday labour which he and his accomplice, Lord
John Russell, have brought. It seems that the letters
directed to Cabinet Ministers, or the officers of
Government, are not to be detained, but are still "to
be forwarded on Sunday by the ordinary dispatch."
Now, as Lord John Russell has been a party to the
hindrance of letters on Sunday ; as he avows that he
quite aware of the inconvenience; and as he is a
very Ih.nourable and well-disposed man, it is to be pre-
sumed that he will not evade any offer on this point
which might tend to mitigate the inconvenience. We
would suggest, therefore, that any persons who have
letters to be transmitted on the Sunday should direct
them to the care of Lord John Russell, and no doubt
he will see to their being properly posted early on
Monday morning.
