We publish several letters bearing on the New Land Regulations, which appear in the columns of the Independent. Two are addressed by Messrs. Sewell and Wake field to Messrs. Brittan and Tancred, who are made—-with all respect be it written— the pegs to hang dissertations on, in which Sir George Grey and his recent doings are denounced. To do these gentlemen justice they have adopted no half measures, but have com menced an active warfare against his Ex cellency. With the legal skill of the former, combined with the, large experience of the latter arrayed against him, we think his Ex cellency will have considerable difficulty in meeting and parrying their attacks, or satis factorily shewing to the public that he is ei ther authorised by the letter or justified by the spirit of. the Act in forestalling the functions of the Parliament of New Zealand. The general feeling at Wel lington, as here, is, that however desi rable it may be for the interests of the Colony that the price of land be so re duced as to hold out attractions to Immi grants, yet. that it was the province of the General Assembly, representing the opi nions of the people, to decide that question. That it was not for the Executive to step in at the eleventh hour and forestall their decision by taking advantage" of a vaguely worded clause in the Constitutional Act, and thus to render their controul over the Waste Lands a nullity and a sham. It was never so intended by the Imperial Parliament, nor, indeed, we should hope, by Sir J. Paking ton ; and we shall refuse to believe he would either suggest or sanction such a vi olation of the spirit of the Act, until his Ex cellency produces the instructions heassumes to possess, and which Mr. Sewell has applied for officially to the Colonial Secretary, but hitherto, to our knowledge, without success. Even admitting the new regulations to be beyond all question advantageous to the colony—granting them even to be framed in accordance with popular feeling—to have brought them forward at such a time as this, is an act of deliberate hostility to the Settlers, to whom, especially, it should have been left to decide on the necessity of making, in so hasty and indecent a manner, such important organic changes materially affecting their interests.
