Letters from Port Nicholson, dated the 21st April, reached London

yesterday. The Company's emigrant-ship Bolton, containing among

other passengers the Magistrate Mr. Butler, and the clergyman Mr. Churton, arrived on the previous day. The surveys at Lambton Harbour were making progress. A pilot has been stationed at the western head of the harbour, where a flag-staff and signal-station, visible in the offing, were to be erected. A fortress had been built on the summit of Somes Island. The second number of the New Zealand Gazette, dated 18th April, arrived by the same conveyance, (the first number having been published in London previous to the departure of the colonists.) This newspaper contains numerous advertisements, and indicates a considerable commercial progress of this new com• munity, which bed landed from England only a few weeks. The most important molts, however, is that of the proclamation of a Provisional Constitution, ratified and sanctioned by the sovereign native chiefs of the district of Port Nicholson—this part of New Zealand not having been ceded in sovereignty to the British Crown.

The Company's emigrant-ship SlaMs Castle, Captain Petrie, with one hundred and sixty labouring emigrants and several cabin pas- sengers, left the London Docks yesterday, (Friday,) and will proceed immediately, She is to be succeeded by the Lady Nugent early in October.
