(Communicated. ) We appear to be retrograding of late in more ways than one. Tenders are called for the conveyance of Her Majesty’s mails to this place once a-week, for a period of two years, commencing ou Januaary 1 next. During the past 12 years wo have had the mails delivered twice a-week, with two out ward mails per week; but henceforth (as per notice of tenders) we shall have to ho content with fewer privileges. Our paper messengers also will arrive only once a week I would most assuredly advise that an expression of opinion be given by the residents on this subject. If silence is maintained, the signification will be consent to the meditated change. In matters of this kind the authorities are guided by returns, irrespective of anything else, and as it is not to be supposed that they can be informed of all the circumstances, it be hoves the people to enlighten them. A respectfully-worded memorial from tire mine-holders, station-holders, and others, pointing out the great disadvantages of the proposed change, should have the desired effect. At any rate it would show that the people were alive to their own interests, and if the worst came they could console them selves witli the fact of having made an attempt to prevent the perpetration of so great an injustice. There are divers rea sons assigned for the intended change, but the probable cause is that, of late, the bulk of the correspondence which should pass through our post-office is carried by private hands, and posted elsewhere, few c iring to trouble our not over-obliging postmaster. One instance will suffice; Some time ago a letter, addressed to one of the station managers, found its way to the post-office, but, having a docket upon it for 2d., it was thrown by, and (after the prescribed term) was sent to Wellington as an unclaimed letter, and returned to the writer. Again, some think that the changing of the post master so frequently tends to help on the retrogade step. Some time ago the post master left for Clyde, Cromwell, and Ban nockburn, and appointed the manager of the Cromwell Company to act in his stead for a period of some weeks ; but as the newly-appointed post-master had made him self rather conspicuous in the late strike, very few patronised the post-office.
