There is another reason why the Conservatives are imperatively called upon to unite. Recent disclosures of a very startling nature have forced upon us the conviction, that the Whigs are worse than weak, and that they cannot be depended on as steadfast guardians of the crown. There is more in the famous letter written by Mr Thomas Young, formerly private secretary to Lord Melbourne, than meets the eye. We attach no undue importance to this epistle--we shall not stoop so low as to examine the motives and intention of its author. His own attempted explanation is, if possible, more damning than the treasonable missive itself. We could only, were we to exhaust our whole powers of illustration, repeat what has been already stated in the masterly article of the _Standard_. It is as clear as day, that at the time of the passing of the Reform Bill, the underlings of the Whig administration were cognisant of a hideous project for a violent and bloody revolution, and that, to take the mildest point of view, they concealed that knowledge from their masters. Franks were obtained _from the Home Office_, for the purpose of suborning the loyalty of at least one officer, high in his Majesty's service, and proposing to him the odious part of a leader in a popular insurrection. Whether that letter, written as it probably was in the fullest confidence, ought or ought not to have seen the light, especially after the lapse of so many years, is a matter with which we have no concern. That is a question which is only personal to Mr Young and his correspondent; but we have the document, and the whole nation is entitled to inquire into its tenor. And never, upon any accusation of so grave a nature, was a more miserable defence preferred. In fact there can be, and there is, no escape from the legitimate conclusion. At that time a section of the Whigs were ready, for the sake of carrying their own scheme, not only to have connived at, but to have lent their whole influence to a popular outbreak and rising, which might, in all human probability, have been subversive of the constitution of the country. Lord Melbourne might not have known of that letter: we go farther, and state our positive opinion that he was utterly ignorant of its existence, because, however we may have differed from him in politics, he is a man whose personal honour and loyalty have always been free from a stain. We believe--and are glad in stating it--that he was utterly ignorant of the vile treason which was hatching in his own department; but we shall not extend the same shelter of belief to others of his unpatriotic party. That treason was meditated is plain; and very thankful shall we be if the higher order of the Whigs shall take the pains, by disavowing and repudiating the acts of their subordinates, and by withdrawing from those implicated the unmerited rewards of their sedition, to clear themselves from the heavy suspicion which this document undoubtedly affixes on their loyalty. It is a
